Answer Key for the Week of 5/18/2020

 A Trip to the Movies
 1. There are ​6 rows​ in the theater. Each row has 9 seats so 54 ÷ 9 = 6 rows.
 2. Kris is in ​seat 15.​ Since there are 9 seats in each row and Kris is 4 rows in
 front of Joe, Kris is 36 seats in front of Joe. 51 − (4 × 9) = 15
 3. Lisa is in ​seat 22.​ The seat to the left of Joe (he is facing the screen) is
 seat 49 = 51 − 2 . She is 3 rows in front of Joe, so she is 3 × 9 = 27 seats in
 front of seat 49. (51 − 2) − (3 × 9) = 22

4. There are ​12 seats ​in each row in the second
 theater. Because seat 100 is directly in front of seat
 88, we can subtract 100 − 88 = 12 to find the number
 of seats in each row.
5. There are ​10 rows​ in the theater in all. Seats 100 -
 102 are in the 9th row because the row starts at seat
 97 and ends at seat 108 since 12 × 9 = 108 .
6. There are ​120 seats​ in the theater in all. Since the
 9th row is the next-to-last row in the theater, there
 are 10 rows in theater with 12 seats in each row so
 12 × 10 = 120 .

 Photographs Previous Week’s Sudoku

1. Diagram 1’s ​small photographs are ​2” x 3”.​ The
 6” height is split in half making each small
 photograph 3” high. To keep things in proportion,
 the small photograph width must be 2”.

Interpreting Figures of Speech, Allusions,
and Connotations
ELA RL.7.4, RI.7.4, L.7.5a, ELD PI.7.6, PI.7.8

Authors will include figures of speech, allusions, and words with connotative
meanings in their writing. It is up to you to analyze how an author’s choice of
words affects the meaning and tone of a text.
A figure of speech is an imaginative way of using words to express ideas that are
not literally true. There are several kinds of figures of speech. The most common
are similes, metaphors, and personification. All of them are types of comparisons.
A simile compares two unlike things using the word like or as.
 • T hat cheese smells like dirty socks.
 (The writer compares cheese to socks, using the word like.)
 • Juan is as hungry as a bear.
 (The writer compares Juan to a bear, using the word as.)

A metaphor compares two unlike things without using like or as.
 •H  is smile is a ray of sunshine.
 (The writer compares a smile to the sun.)
 • The prairie’s mane of long, yellow grass rippled in the breeze.
 (The writer compares the grass to an animal’s mane.)

Personification describes an object, animal, or idea as though it were human. It
compares non-human things with humans.
 • T he old house’s floorboards groaned under his weight.
 (The writer compares floorboards to people, who can groan. Objects do
 not groan.)
 • The mountain goat danced across the meadow.
 (The writer compares a mountain goat to people, who can dance.
 Animals do not dance.)
Interpreting Figures of Speech in Context When you come across a figure
of speech you don’t understand, ask yourself these questions:
 • What is the context for the figure of speech?
 • What two things is the figure of speech comparing?

Read these sentences and the underlined figures of speech.
 1. I was having a horrible time at the school dance. The ice cream smelled like
 the inside of the janitor’s closet.
 2. The cake was a dried-out kitchen sponge. Even worse, I felt too shy to talk
 with anyone.
 3. Suddenly, the sun broke through the clouds as I saw Maya waving to me
 from across the gym.
 4. Before I knew it, Maya and I were dancing. Suddenly all the gymnasium’s
 fairy lights were winking just at me.

Interpreting Figures of Speech, Allusions, and Connotations continued

Here are one student’s interpretations of the figures of speech.

 1. The context tells me the narrator is having a bad time. This
 simile compares the smell of the ice cream with the smell of a
 janitor’s closet. The figure of speech means that the ice cream
 smells bad. It tells me one reason why the narrator is having a
 bad time.

 2. This metaphor compares a cake with a kitchen sponge. The
 figure of speech means that the cake is dry. It tells me another
 reason why the narrator is having a bad time.

 3. The context tells me that something happens to change the
 narrator’s bad time. The sun doesn’t literally break through
 the clouds, but it seems that way to the narrator when he sees
 Maya waving at him, because now he is no longer having a
 bad time.

 4. The context tells me that the narrator is now having a good
 time. This figure of speech personifies the lights decorating the
 gym. It compares the lights with people winking. The figure
 of speech means that the gym seems like a friendly place.
 Because the narrator is having fun, everything around him
 seems friendly.

An allusion is a reference to a well-known person, place, event, or idea from a
source such as religion, mythology, literature, history, science, or popular culture.
Writers use allusions to communicate rich meaning in just a few words. Here are
the key steps to getting meaning from an allusion in your reading:

 1. Notice an allusion. Often, an unfamiliar proper noun or adjective will
 signal that a writer is making an allusion, as in “He’s such a Romeo.” Because
 allusions carry so much meaning, don’t skip over them if you don’t
 understand them right away.
 2. Identify the source and meaning of the allusion. Take a moment to look
 up the allusion online or in a dictionary or ask someone about it. Find out
 where it comes from and to what it refers.
 3. Connect the allusion to the text. Think about how the allusion fits the text
 you are reading and why the author might have chosen it. Many allusions
 contribute to the tone or point toward the theme of a piece of writing.

 ALLUSION SOURCES
 SOURCE EXAMPLES
 The Bible • The birth, life, death, and resurrection of Jesus
 • The creation of the world
 • Adam and Eve in the garden of Eden
 • Moses leading the Israelites out of Egypt
 Classical literature • The Odyssey, including the story of the Cyclops
 and mythology • The myth of King Midas and the golden touch
 • Fairy tales, such as “Cinderella” and “The Three Little
 Pigs”
 • Aesop’s fables, such as “The Tortoise and the Hare”
 Shakespeare and • Romeo and Juliet, Hamlet, and other well-known
 other classics Shakespeare plays
 • Beowulf
 • Gulliver’s Travels
 • More recent classics, such as 1984 and To Kill a
 Mockingbird
 History, science, • Key events such as the American Revolution and World
 and popular culture War II
 • Inventions such as the light bulb and telephone; the
 space program
 • Popular characters such as Superman and the Simpsons

Identifying Allusions Read this passage, watching for clues about allusions it
may contain. Then notice how one student answered the questions that follow
the passage.

 Mayor Ford, with the carelessness of Icarus, flies toward the sun
 of supporting too much downtown development. Warnings from city
 planners, like those of Daedalus, are ignored. The resulting traffic
 problems will bring the mayor crashing back to Earth.

 1. Which words in this passage are clues that an allusion is being used?

 Icarus, flies toward the sun, Daedalus, and crashing back to Earth
 may all be clues.

Copyright © by Houghton Mifflin Harcourt Publishing Company

California Standards Support and Enrichment 3 Interpreting Figures of Speech, Allusions, and Connotations
Interpreting Figures of Speech, Allusions, and Connotations continued

 2. Which sources could you consult to understand this allusion?

 I searched online for Icarus and Daedalus and found out that
 they’re from a Greek myth. I read the myth online: Against his
 father’s warning, Icarus flies too close to the sun using wings held
 together with wax. The sun’s heat melts the wax, so his wings fall
 apart and he falls from the sky.

Words have two kinds of meaning. A word’s denotation is its literal meaning—
one you can look up in a dictionary. A word’s connotations are the ideas and
feelings associated with it. Connotations may be positive or negative. By
choosing words with particular connotations, an author conveys both meaning
and tone, or an attitude toward the topic. Consider these sentences:
 T he cat slinked into a corner and fixed us in an icy stare.
 The cat tiptoed into the room and watched us with curious eyes.

In the first sentence, the words “slinked” and “icy stare” make the cat seem sneaky
and unfriendly, conveying a negative tone toward the cat. In the second
sentence, the words “tiptoed” and “curious eyes” make the cat seem gentle and
intelligent, creating a much more positive tone.

Interpreting Connotations Read these sentences and look for words with
strong connotations. Then see how one student analyzed the impact of each
author’s word choices.

 1. The carnival delighted our senses with an array of colorful sights, festive
 sounds, and delicious smells.
 2. The carnival assaulted our senses with blinding lights, a jumble of repetitive
 noises, and the smell of greasy foods.

 1. The author uses the words delighted, colorful, festive, and
 delicious to describe the carnival. These words have positive
 connotations. The author’s attitude is that the carnival is
 exciting and fun.

 2. The words assaulted, blinding, jumble, repetitive, and greasy
 have negative connotations. This author’s word choices
 suggest that he or she finds the carnival overwhelming and
 unpleasant.

Practice and Apply Read the following passage, and answer the questions that
follow it.

 from “Antaeus”
 by Borden Deal
 The laborious earth just lay there during the cold months, inert
 and lifeless, the clods lumpy and cold under our feet when we walked
 over it. But one day it rained, and afterward there was a softness in the
 air, and the earth was live and giving again with moisture and warmth.
 That evening T.J. smelled the air, his nostrils dilating with the odor
 of the earth under his feet. “It’s spring,” he said, and there was a
 gladness rising in his voice that filled us all with the same feeling. “It’s
 mighty late for it, but it’s spring. I’d just about decided it wasn’t never
 gonna get here at all.”
 We were all sniffing the air, too, trying to smell it the way T.J.
 did, and I can still remember the sweet odor of the earth under our
 feet. It was the first time in my life that spring and spring earth had
 meant anything to me. I looked at T.J. then, knowing in a faint way the
 hunger within him through the toilsome winter months, knowing the
 dream that lay behind his plan. He was a new Antaeus, preparing his
 own bed of strength.

Questions
 1. What figures of speech are used in this passage?
 2. What allusion is used in the passage? What does it mean in this context?
 3. How do the figures of speech and allusions affect your understanding of
 the text?
 4. What words in the passage have positive or negative connotations? What
 tone or attitude do the words convey about winter and spring?

 Galileo Lesson

 Central Historical Question:
 Was Galileo really a heretic?
 In 1633, scientist Galileo Galilei was
 Materials: convicted of heresy by the Inquisition.
 He was forced to recant his beliefs and
 • Background PowerPoint spent the rest of his life under house
 • Heliocentrism and the Catholic Church Timeline arrest. Students may be surprised to
 learn Galileo's crime: teaching the sun,
 • Documents A & B
 rather than the earth, is at the center of
 • Documents C & D the solar system. In this lesson,
 • Guiding Questions students explore three primary sources
 and one New York Times article to
 answer the question: Was Galileo really
Instructions: a heretic?

1. Warm-up: Is the earth or the sun in the center of the solar system? How do we know?
 a. Hopefully we remember that the sun is in the center of the solar system. We
 should know this because of scientific discoveries. Scientists have conducted
 extensive research on this topic.
 b. Consider: If you didn’t know about any of these scientific studies and only knew
 what you could see or observe, would you think that the sun or the earth orbits
 the other?
We might say it seems like the sun moves around the earth. We can’t feel the earth
moving, and it looks likes the sun moves across the sky throughout the day.

c. Remember that in early modern Christian Europe, most people, even very smart
 people, believed the earth was the center of the universe and the sun moved around
 the earth.
d. During the Scientific Revolution, some people, notably Copernicus, began to challenge
 this belief. One person, Galileo, became very famous for this belief because it got him in
 trouble with the Catholic Church.

2. Background PowerPoint and Timeline
 a. Take out Heliocentrism and the Catholic Church Timeline and review as you view
 the PowerPoint presentation.
 b. Make sure to note the following key points on each slide:
 i. Slide 1: Galileo. During the 17th century, European scholars increasingly
 tried to understand the natural world through science. Galileo Galilei was
 one of these scientists, and he is sometimes called the Father of Scientific
 Reason.
 ii. Slide 2: Models of the Solar System.

 STANFORD HISTORY EDUCATION GROUP sheg.stanford.edu
1. Geocentrism is a model that places the earth at the center of the astronomical
 system. In this model, other bodies in space orbit around the earth. Geo comes from
 the Greek word for earth.
2. Heliocentrism is a model that places the sun at the center of the astronomical system.
 In this model, other bodies in space orbit around the earth. Helio comes from the
 Greek word for the sun.
3. We know that the earth orbits the sun, which is at the center of the solar system.
 Across centuries some astronomers debated models of their known universes. We
 know that some early Greek and Indian astronomers challenged aspects of the
 heliocentric model. Some medieval Islamic and western European astronomers also
 raised doubts about the model. But in 17th-century Italy, people didn’t know that the
 solar system was but a tiny piece of a much larger galaxy and universe. In Galileo’s
 time and place, nearly everyone believed that the earth was at the center of the
 universe (geocentric model). Even very smart people did not believe the Earth orbited
 because they couldn’t feel it move.
 iii. Slide 3: The Problem. The heliocentric model seemed to contradict the Bible. This
 passage from Joshua is an example.
iv. Slide 4: Copernicus. Copernicus was one of the first medieval European scientists to
 challenge this idea, but he knew how radical his theory was, so he waited to publish
 his book until right before his death.
 v. Slide 5: The Council of Trent. The Catholic Church convened the Council of Trent in
 1545 to stop the spread of Protestantism and to revive the Catholic Church. The
 council decreed that only the Catholic Church could interpret the Bible and
 established the Holy Office of the Roman Inquisition to persecute heretics. A heretic
 is someone whose beliefs go against the Church’s official beliefs.
vi. Slide 6: Giordano Bruno. Giordano Bruno was another scientist who supported the
 heliocentric model. Additionally, he correctly theorized that the sun is just one of
 many moving stars and that the universe contained many planets orbiting other
 stars. In 1600 he was tried before the Inquisition and burned at the stake. We don’t
 know the exact charges he was found guilty of, and in addition to his astronomical
 theories, he held many religious beliefs contrary to the Church’s doctrines.
vii. Slide 7: Galileo. Galileo was born in Pisa, Italy in 1564. He was a religious man and
 even wanted to be a monk at one point. Instead, he studied motion and physics at
 the University of Pisa. The more he studied, the more he started to believe the
 heliocentric theory. In 1609, he built a telescope. The observations he made from
 the

STANFORD HISTORY EDUCATION GROUP sheg.stanford.edu
telescope convinced him that Copernicus’s heliocentric model was right, and Galileo
and began teaching the model to his students.
viii. Slide 8: Conflict. In 1615, The Church warned Galileo to stop teaching the
 heliocentric model. In 1616, the Church banned the works of Copernicus and
 others that supported heliocentrism. Galileo continued to write and publish ideas
 about his theory. Pope Urban VIII told Galileo he could discuss Copernicus’s
 theory, as long as he didn’t say it was absolutely true. His 1632 book, Dialogue
 Concerning the Two Chief World Systems, came too close to arguing the theory
 was true, and he was brought before the Inquisition as a heretic the following year.
 ix. Slide 9: Central Historical Question. Using these facts and two documents (one
 from Galileo and one from the Church) you are going to decide for yourself: Was
 Galileo really a heretic?
 x. Wait to view Slides 10 & 11 until after you make your judgment.
3. Document A: Galileo’s Letter (1615)
 a. Take out Document A: Galileo’s letter to Duchess Christina defending his
 beliefs.
 b. Read the document and answer questions.
 c. Consider:
 i. Context: We should recognize that in 1615, the year of this letter, the
 Church warned Galileo to stop sharing his beliefs in public. Therefore,
 it makes sense for Galileo to write a letter defending these beliefs. Also
 the Church executed Bruno for similar beliefs in 1600, so Galileo might
 have wanted to prevent the same thing from happening to him.
 ii. Close-reading: Galileo’s beliefs about the sun and earth seemed to go
 against some passages in the Bible. However, Galileo believed people
 were interpreting those passages incorrectly.
 iii. Context: This might be a more difficult question. The Catholic Church
 probably won’t accept Galileo’s defense. He did not believe he was
 going against the Bible, but he was also interpreting passages of the
 Bible on his own. The Church was very nervous about people doing
 this because of what had happened with Martin Luther and the
 Protestant Reformation.

4. Document B: Cardinal Robert Bellarmine’s letter (1615)
 a. We are now going to read the Catholic Church’s point of view in a letter from
 Cardinal Robert Bellarmine. This is not a direct response to Galileo’s letter to
 Duchess Christina, because Bellarmine never saw that letter, but he
 addresses many of Galileo’s points.
 b. Take out Document B and read the document and answer the questions in
 pairs. As you read the letter, you should see if

STANFORD HISTORY EDUCATION GROUP sheg.stanford.edu
Bellarmine made any of the points they predicted when discussing the
 context of Document A.
 c. Consider:
 i. Close reading: Bellarmine says it is obvious from human experience
 that the earth stands still and the sun moves. Plus this is what the
 Bible says. Not only does the Bible say this, but all of the Church’s
 leaders have interpreted these passages literally. Therefore,
 according to Bellarmine, Galileo’s interpretation of these passages
 must be wrong. Further, Bellarmine suggests the real issue was
 denying any part of the Bible. His concern was that if people denied
 one part of the Bible, they could deny more, or even all, of it.
 ii. Context: New Renaissance ideas, the Protestant Reformation, and
 increasingly powerful monarchs were already challenging the
 Catholic Church’s power in Europe. If the Church began to admit
 that it might be wrong about one thing, it could have opened the
 door to people challenging other Church doctrines. The Church
 feared it could lose even more power.
 5. Judgment

 ci. Now that you have read these two documents and the facts from the
 timeline, you are going to make a judgment about Galileo: Was he really a
 heretic?
 i. Remember that a heretic is someone whose beliefs go against the
 teachings of the Church. Therefore, we should not try to prove
 Galileo’s theory was right. Instead, we should focus on the issue of
 heresy.
 ii. Galileo’s trial focused on whether he was a heretic. Based on the
 evidence in the lesson, you should formulate your own rulings in
 response to the question of whether Galileo was a heretic.
 cii. Complete the Judgment section on their Guiding Questions.
 ciii. Reflect: Was Galileo really a heretic?
 i. Yes, Galileo was a heretic: He went against the teachings of the
 Church. The Church told him to stop teaching the heliocentric
 model, and he did it anyway. He tried to interpret the Bible on his
 own, which the Church said individuals could not do.
 ii. No, Galileo was not a heretic: He may have gone against a few of
 the Church’s rules, but he still believed in the Bible. He said that the
 Bible was true, but people might not understand everything it says.
 He said that people were interpreting the Bible incorrectly, not that
 the Bible was wrong.
 civ. How do you think the Catholic Church ruled in 1633?

STANFORD HISTORY EDUCATION GROUP sheg.stanford.edu
a. Documents C and D show us how the Catholic Church’s position on science and
 the Galileo issue has changed over the centuries. These documents provide more
 context about Galileo’s case.
b. Read Documents C & D and answer the Guiding Questions.
 i. Document C: Galileo was found guilty of teaching a model
 (heliocentrism) that went against the Bible. He was also guilty of arguing
 something could be true even if the Church believed it contradicted the Bible.
 ii. Document D: Pope John Paul II admitted that the Church’s treatment of
 Galileo was wrong. He said the Church used the knowledge it had at the time
 and misinterpreted the Bible. It made something that was scientific into
 something about faith. This was basically what Galileo had argued.

7. The Ruling
 a. Return to the PowerPoint
 i. Slide 10: What happened to Galileo? Under the threat of punishment
 and torture, Galileo agreed to recant, or take back, his beliefs and
 was sentenced to house arrest. He died in 1642.
 ii. Slide 11: After Galileo. In 1661 Isaac Newton taught Galileo and
 Copernicus’s ideas in England.
8. Final Discussion: Context
 a. Why was it easier for the Church to admit Galileo was right in 1979, than it
 was in 1633?
 b. Based on this controversy, how was the historical context of the 17th century
 different from 1979?
 c. How might people understand and study our beliefs in 300 years?

Document A: Galileo’s Letter (Modified)

Galileo wrote the following letter to Duchess Christina of Tuscany in 1615.
In this letter, he defends himself against the charges of heresy.

Some years ago I discovered in the heavens many things that had not
been seen before our own age. The novelty of these things . . . stirred up
several professors against me. They hurled various charges and published
numerous writings filled with vain arguments, and they made the grave
mistake of sprinkling these with passages taken from places in the Bible,
which they failed to understand properly.

The reason given for attacking the opinion that the earth moves and the
sun stands still is that in many places in the Bible one may read that the
sun moves and the earth stands still. Since the Bible cannot err, it follows
that anyone who claims that the sun is motionless and the earth movable
takes an erroneous and heretical position.

With regard to this argument, I think in the first place that it is very pious to
say and prudent to affirm that the holy Bible can never speak untruth-
whenever its true meaning is understood. But I believe nobody will deny
that the Bible is often very complex, and may say things which are quite
different from what its bare words signify. . . .

I do not believe that the same God who has given senses, reason and
intellect has intended us to not to use them. . . . He would not require us to
deny sense and reason in physical matters of direct experience. . . . Can an
opinion be heretical and yet have no concern with the salvation of souls?

Document B: Cardinal Bellarmine
Cardinal Robert Bellarmine was in charge of dealing with difficult issues
connected to the Church’s power and beliefs during the Galileo controversy. He
wrote the following letter to Paolo Antonio Foscarini in response to Foscarini’s
book defending Galileo. Historians don’t believe Bellarmine ever saw Galileo’s
1615 letter (Document A).

As you know, the Council [of Trent] prohibits interpreting the Scriptures contrary
to the common agreement of the holy Fathers. And if you would read not only the
Fathers but also the commentaries of modern writers on Genesis, Psalms,
Ecclesiastes and Joshua, you would find that all agree in explaining that the
sun is in the heavens and moves swiftly around the earth, and that the earth is
far from the heavens and stands immobile in the center of the universe. . . .

It would be just as heretical to deny that Abraham had two sons and Jacob
twelve, as it would be to deny the virgin birth of Christ, for both are declared by
the Holy Ghost through the mouths of the prophets and apostles. . . .

I say that if there were a true demonstration that the sun was in the center of the
universe and the earth in the third sphere, and that the sun did not travel around
the earth but the earth circled the sun, then it would be necessary to proceed
with great caution in explaining the passages of Scripture which seemed
contrary, and we would rather have to say that we did not understand the
Scripture than to say that something was false which has been demonstrated.
But I do not believe that there is any such demonstration; none has been shown
to me. . . . [One] clearly experiences that the earth stands still and that his eye is
not deceived when it judges that the moon and stars move.

Document C: Condemnation of Galileo (Modified)

In 1632, Galileo, who had been teaching and writing about the idea that the Earth
moved around the sun, was summoned to Rome to stand trial. After questioning
the relevant witnesses, the judges issued the following condemnation of Galileo.

You, Galileo of Florence, were denounced in 1615, by this Holy Office, for
holding as true a false doctrine taught by many, namely, that the sun is
immovable in the center of the world, and that the earth moves . . . also, for
explaining the Scriptures according to your own meaning. Therefore . . . by the
desire of his Holiness and the Most Eminent Lords, Cardinals of this supreme
and universal Inquisition, the two propositions of the stability of the sun, and the
motion of the earth, were qualified as follows:

 1. The proposition that the sun is in the center of the world and immovable
 from its place is absurd, philosophically false, and formally heretical;
 because it is expressly contrary to Holy Scriptures.
 2. The proposition that the earth is not the center of the world, nor
 immovable, but that it moves is also absurd, philosophically false, and,
 theologically considered, at least erroneous in faith.

Therefore, in the most holy name of our Lord Jesus Christ and of His Most
Glorious Mother Mary, We pronounce, judge, and declare, that you Galileo . . .
have made yourself suspected by this Holy Office of heresy, that is, of having
believed and held the doctrine (which is false and contrary to the Holy and Divine
Scriptures) that the sun is the center of the world, and that it does not move from
east to west, and that the earth does move, and is not the center of the world;
also, that an opinion can be held and supported as probable, after it has been
declared contrary to the Holy Scripture.

Document D: New York Times Article (Modified)

In 1979, Pope John Paul II ordered an investigation of the Catholic
Church’s treatment of Galileo. The following article from 1992 summarizes
the conclusions of the investigation.

Vatican Science Panel Told By Pope: Galileo Was Right

Moving formally to right a wrong, Pope John Paul II acknowledged in a
speech today that the Roman Catholic Church had erred in condemning
Galileo 359 years ago for asserting that the Earth revolves around the Sun.

The address by the Pope before the Pontifical Academy of Sciences closed
a 13-year investigation into the Church's condemnation of Galileo in 1633,
one of history's most notorious conflicts between faith and science. Galileo
was forced to recant his scientific findings to avoid being burned at the
stake and spent the remaining eight years of his life under house arrest.

John Paul said the theologians who condemned Galileo did not recognize
the formal distinction between the Bible and its interpretation.

"This led them move a question which in fact pertained to scientific
investigation into the realm of the doctrine of the faith.”

Though the Pope acknowledged that the Church had done Galileo a wrong,
he said the 17th-century theologians were working with the knowledge
available to them at the time.

Eat your veggies: NASA expands plant-growing
program on space station

As people prepare their gardens for spring, NASA is trying something a little different: a vegetable
garden in space.

On Tuesday, an Atlas V rocket blasted into space from NASA's Cape Canaveral Air Force Station. It
carried supplies and scientific equipment to the International Space Station (ISS). Onboard was a
new experiment, the size of a mini-fridge. It's called the Advanced Plant Habitat (APH).

Astronauts will use the APH to expand their ability to grow vegetables and other plants on the
station, some of which will end up on the menu.

Healthy Food Source For Astronauts

The ability to raise plants in space has been a NASA priority for years. Future human expeditions
to Mars would require a reliable food supply. Astronauts would need food for long periods both
during the trip to, and on the surface of, the Red Planet. Experiments like APH will be an
important test for finding the best ways to prepare veggies outside Earth, says Chris Wolverton.

 This article is available at 5 reading levels at https://newsela.com.
He's a professor of botany—the study of plants—at Ohio Wesleyan University in Delaware, Ohio,
and currently is studying plant gravity on the ISS.

For now, most experts believe astronauts will bring food from Earth to stay fed, Dr. Wolverton
tells The Christian Science Monitor. Plants, especially leafy greens, are excellent at making
vitamins and other nutrients that keep humans healthy, he says.

The new Advanced Plant Habitat is actually an expansion of a previous NASA idea from 2015,
known as the Vegetable Production System (also known as "Veggie"). The Veggie program soon
produced lettuce for the ISS crew. It was the first food grown by NASA in space specifically for
astronauts to eat.

LED Lights Used To Grow Plants

The success of Veggie encouraged scientists to go even farther with the APH project. The old
Veggie system had indoor plants that lived in the unfiltered air of the space station. The new APH
system will allow astronauts to more fully control the environment inside the growing room. APH
will also have brighter LED lights, which mimic the light of the sun. Some of these lights shine
more powerful white and infrared light, and they can potentially quadruple the plants that were
grown with the old Veggie system.

"It's really a way for the scientists to modify the environment: the light, the water, the
atmosphere," program manager Bryan Onate told reporters in March. Scientists will learn lots of
important information about future food production on Mars, Onate says.

APH isn't just about what's on the astronauts' dinner table. The unit comes equipped with a
variety of sensors and cameras. These will be used to monitor plant growth and give information
on how plants adapt to a non-Earth environment. Microgravity, radiation, and other space-related
changes can affect the growth of living things in unexpected ways. If future astronauts are going to
be using crops grown in space as their main food source, scientists want to know about any
possible challenges now.

Gravity Challenges In Growing Plants

One of the major problems with growing plants in low gravity, Wolverton says, is due to the way
water moves. It tends to form into droplets rather than into a steady flow, he says. In turn, when
these droplets form on a plant, they can burst at a moment's notice, which floods the plant and
chokes it of its needed oxygen.

There are other challenges, too. Without normal Earth gravity, plants can even have trouble telling
which way is up, he adds.

"Gravity is a major signal to plants that tells them which way to grow," says Wolverton.

For its first experiments, the APH system will be tested with two kinds of seeds. First, astronauts
will attempt to grow arabidopsis, a small leafy vegetable in the same family as cabbage. They'll also
try to grow a type of wheat. If all goes as planned, arabidopsis will be the main crop for APH's first
experiment, which has been designated Plant Habitat 1.

Preparing For Martian Expeditions

Eventually, scientists hope astronauts will be able to use the system to grow larger and more
nutrient-heavy plants. But ultimately, the goal of APH and other projects like it is simply to
determine the possibility of plant growth in environments other than Earth. This will prepare
them for Martian expeditions, says Edward Guinan. He's a professor of astronomy and
astrophysics at Villanova University in Pennsylvania.

"To grow plants in Mars' cold climate, plants will need to be sheltered in greenhouses," Dr. Guinan
tells the Monitor via email. "The amount of sunlight (solar radiation) on Mars is about 50 percent
of that of the Earth since Mars is 1.5 times further than the Earth from the Sun."

Lack of light, increased radiation, and unfriendly Martian soil could pose significant challenges for
plants in an alien world. But without experimentation, there's no way to know for sure how Earth
vegetables would live on Mars.

"Certain plants might do better than others," Guinan adds. "The experiments on the International
Space Station (ISS) will help answer some of these questions."

Farming on Mars: Special "aerogel" sheets
might make it possible

MSSS/handout/EPA

Astronauts bound for Mars someday have something to look forward to. When they sit down to
dinner on the barren red planet, they can have fresh food grown on Mars.

The harsh environment on Mars has always made growing food a difficult prospect, but scientists
believe they have figured out a solution to the problem. Sheets of material can transform the cold,
dry surface into land fit for farming.

Mimicking Earth's Greenhouse Effect

The "aerogel" sheets work by mimicking Earth's greenhouse effect. The energy from the sun is
trapped on Earth by carbon dioxide and other gases. Spread out in the right places on Mars, the
sheets would warm the ground and melt enough ice to keep plants alive. They could be important
for supporting people with food grown on Mars rather than food brought from Earth.

 This article is available at 5 reading levels at https://newsela.com.
Robin Wordsworth worked on the sheets at Harvard University in Cambridge, Massachusetts. He
said, "If we want to make sustainable habitats on another planet using present-day technology,
this approach could be very useful." It can be done on a small or large scale, he said. "The area
covered could be anywhere from a few square meters to large regions of the planet."

If humans ever decide to spread beyond Earth, as the late scientist Stephen Hawking said we must,
then growing food in alien worlds will be a skill that has to be mastered. However, on Mars the
conditions are not favorable. The planet is bitterly cold and dry and bombarded by radiation. The
soil contains potentially toxic chemicals and the wispy atmosphere is low on nitrogen. Plants need
nitrogen to grow.

In the past, scientists and science fiction writers have proposed "terraforming" barren worlds. It's
an approach that calls for the whole atmosphere to be rebuilt. In 1971 the American astronomer
Carl Sagan suggested that vaporizing the northern polar ice cap on Mars might release enough
water into the atmosphere to do the trick. More modest ideas have involved erecting greenhouses
instead.

Creating A Fertile Oasis Without Harming Mars

The aerogel sheets do not solve all of the problems. Still, they could help future space residents
create a fertile oasis where plants and other organisms using photosynthesis can take root on other
planets. The plants would grow only beneath the sheets. So the risk of harming the rest of Mars
with foreign life forms would be minimal, Wordsworth said.

The researchers studying the sheets included scientists at NASA and the University of Edinburgh
in Scotland. The aerogel used to make the sheets is made up of 97 percent air. The scientists
showed that sheets of the aerogel 2- to 3-centimeters (about 1 inch) thick blocked harmful
ultraviolet rays. They also allowed visible light through for photosynthesis and trapped enough
heat to melt frozen water locked in Martian soil.

Placing the aerogel shields over icy regions of the Martian surface "could therefore allow
photosynthetic life to survive there," the researchers wrote in Nature Astronomy. The sheets could
be laid directly on the ground to grow water plants. They also could be suspended to provide room
for land plants to grow beneath them.

Wordsworth said, "The best place to try this is similar to where you'd want to land humans" on
Mars. Those are places that are not too close to the equator of Mars and not too close to the poles.
Yet they need to be "close enough to the polar caps that near-surface ice deposits are still scattered
around," he said.

"You can imagine this being used in a number of ways." The quickest and easiest would be a small
test with a robotic lander, he said. Later it could be used to feed people on Mars. "In the longer
term it could be used in support of human exploration missions, and eventually to produce long-
lived habitats," he said. The goal would be to have the habitats support themselves as much as
possible, he said.

 Writing Prompt: Explain how scientists plan to grow plants on Mars. What difficulties
 might they experience growing plants on Mars? How could growing plants on Mars harm
 the planet and why would researchers be concerned about this?
