Every substance around you is made of one or more chemical elements, or types of atoms. Substances that are made of only one chemical element are elementary substances. Substances that are made of two or more chemical elements bonded together are compounds.
Every chemical element is represented by its own symbol. For some elements, the symbol is one capital letter. For other elements, the symbol is one capital letter and one lowercase letter. For example, the symbol for the element fluorine is F, and the symbol for the element beryllium is Be.
The symbol for each element in a substance is shown in the substance's chemical formula.
An elementary substance is represented by a chemical formula that contains only one symbol.
The symbol may be followed by a subscript. A subscript is text that is smaller and placed lower than the normal line of text. A subscript is included when the atoms in the elementary substance are bonded to form molecules. The subscript tells you the number of atoms in each molecule.
For example, the chemical formula for the elementary substance oxygen is O2. The formula has a subscript of 2. This subscript tells you that there are two atoms in the molecule represented by this chemical formula.
The chemical element represented by the symbol O is also called oxygen. So, the formula O2 tells you that each molecule of O2 contains two oxygen atoms.
A compound is represented by a chemical formula that contains multiple symbols.
For example, in the compound beryllium fluoride, there is one beryllium atom for every two fluorine atoms. This combination is shown in the compound's chemical formula, BeF2. In the formula, the symbol Be represents one beryllium atom. The symbol F followed by the subscript 2 represents two fluorine atoms.

Question:
Complete the statement.
Silane is ().

0. an elementary substance
1. a compound

[Assistant]
You can tell whether silane is an elementary substance or a compound by counting the number of symbols in its chemical formula. A symbol contains either one capital letter or a capital letter followed by one or two lowercase letters.
The chemical formula for silane is SiH4. This formula contains two symbols: Si for silicon and H for hydrogen. So, the formula tells you that silane is made of two chemical elements bonded together.
Substances made of two or more chemical elements bonded together are compounds. So, silane is a compound.
Therefore my final answer is: 1

An object's speed tells you how fast the object is moving. Speed depends on both distance and time.
Distance tells you how far the object has moved. One unit used to measure distance is the mile.
Time tells you how long the object has spent moving. One unit used to measure time is the hour.
Think about objects moving for the same amount of time. The object that is moving the fastest will go the farthest distance in that time. It is moving at the highest speed.

Question:
Compare the motion of three geese. Which goose was moving at the highest speed?

0. a goose that moved 675miles north in 10hours
1. a goose that moved 575miles west in 10hours
2. a goose that moved 765miles north in 10hours

[Assistant]
Look at the distance each goose moved and the time it took to move that distance. The direction each goose moved does not affect its speed.
Notice that each goose moved for 10 hours. The goose that moved 765 miles moved the farthest distance in that time. So, that goose must have moved at the highest speed.
Therefore my final answer is: 2

There are four kinds of sentences.
A declarative sentence is a statement. It tells about something. A declarative sentence always ends with a period.
I have an older brother and a younger sister.
An interrogative sentence is a question. It asks something. An interrogative sentence always ends with a question mark.
How tall are you?
An imperative sentence is a command. It makes a request or tells someone to do something. An imperative sentence usually ends with a period. If the command shows strong feeling, it ends with an exclamation point.
Read the first chapter by next week.
Look out for that car!
An exclamatory sentence is like a statement, but it shows surprise or strong feeling. An exclamatory sentence always ends with an exclamation point.

Minerals are the building blocks of rocks. A rock can be made of one or more minerals.
Minerals and rocks have the following properties:
Property | Mineral | Rock
It is a solid. | Yes | Yes
It is formed in nature. | Yes | Yes
It is not made by organisms. | Yes | Yes
It is a pure substance. | Yes | No
It has a fixed crystal structure. | Yes | No
You can use these properties to tell whether a substance is a mineral, a rock, or neither.
Look closely at the last three properties:
Minerals and rocks are not made by organisms.
Organisms make their own body parts. For example, snails and clams make their shells. Because they are made by organisms, body parts cannot be  minerals or rocks.
Humans are organisms too. So, substances that humans make by hand or in factories are not minerals or rocks.
A mineral is a pure substance, but a rock is not.
A pure substance is made of only one type of matter.  Minerals are pure substances, but rocks are not. Instead, all rocks are mixtures.
A mineral has a fixed crystal structure, but a rock does not.
The crystal structure of a substance tells you how the atoms or molecules in the substance are arranged. Different types of minerals have different crystal structures, but all minerals have a fixed crystal structure. This means that the atoms and molecules in different pieces of the same type of mineral are always arranged the same way.
However, rocks do not have a fixed crystal structure. So, the arrangement of atoms or molecules in different pieces of the same type of rock may be different!

Question:
Select the one substance that is not a mineral.

0. An antler is made by a living thing. It is a solid.
1. Chrysotile is a solid. It is a pure substance.
2. Pyrite is not made by living things. It is formed in nature.

[Assistant]
Compare the properties of each substance to the properties of minerals. Select the substance whose properties do not match those of minerals.
An antler is made by a living thing. But minerals are not made by living things.
So, an antler is not a mineral.
Pyrite is a mineral.
Chrysotile is a mineral.
Therefore my final answer is: 0

All organisms have pieces of hereditary material called genes, which are passed from parents to offspring. Genes contain instructions for building the parts of an organism. An organism's genes affect its observable traits, including its appearance, its behavior, and which diseases it may have. Genes may have different alleles, or forms, that can cause different versions of a trait.
For example, flower color is a trait in pea plants. The gene for this trait has two possible alleles. Each allele is represented by an uppercase or lowercase letter. The allele F is for purple flowers, and the allele f is for white flowers. Each pea plant has two alleles for the flower color geneone allele inherited from each parent.
An organism's genotype for a gene is its combination of alleles for that gene. So, a pea plant may have a genotype of FF, Ff, or ff for the flower color gene.
An organism's phenotype for a trait is its observable version of that trait, which depends on the organism's combination of alleles. A pea plant may have a phenotype of purple flowers or white flowers for the flower color trait.

Question:
Based on this information, what is Echo's phenotype for the coat color trait?

Measurements are written with both a number and a unit. The unit comes after the number. The unit shows what the number means.
Volume is a measurement of how much space something takes up.
There are many different units of volume. When you are using metric units, volume may be written in units of milliliters or liters.
There are 1,000 milliliters in 1 liter. So, 1 milliliter is much less than 1 liter.
A raindrop has a volume of about 20 milliliters, while a large soda bottle has a volume of 2 liters. The flask shown here measures volumes up to 500 milliliters.

All organisms have pieces of hereditary material called genes, which are passed from parents to offspring. Genes contain instructions for building the parts of an organism. An organism's genes affect its observable traits, including its appearance, its behavior, and which diseases it may have. Genes may have different alleles, or forms, that can cause different versions of a trait.
For example, flower color is a trait in pea plants. The gene for this trait has two possible alleles. Each allele is represented by an uppercase or lowercase letter. The allele F is for purple flowers, and the allele f is for white flowers. Each pea plant has two alleles for the flower color geneone allele inherited from each parent.
An organism's genotype for a gene is its combination of alleles for that gene. So, a pea plant may have a genotype of FF, Ff, or ff for the flower color gene.
An organism's phenotype for a trait is its observable version of that trait, which depends on the organism's combination of alleles. A pea plant may have a phenotype of purple flowers or white flowers for the flower color trait.
Some traits, like flower color in pea plants, are controlled by a single gene. Most plants and animals have a genotype made up of two alleles for these traits. These two alleles determine whether an organism is homozygous or heterozygous for the gene.
An organism with two identical alleles for a gene is homozygous for that gene. A pea plant with the genotype FF or ff is homozygous for the flower color gene.
An organism with two different alleles for a gene is heterozygous for that gene. A pea plant with the genotype Ff is heterozygous for the flower color gene.
The types of alleles in an organism's genotype determine the organism's phenotype. Some alleles have types called dominant and recessive. These two types can cause different versions of a trait to appear as the organism's phenotype.
A dominant allele causes its version of the trait to appear even when the organism also has a recessive allele for the gene. In pea plants, the F allele, which causes purple flowers, is dominant over the f allele. A pea plant with at least one F allele will have the F allele's version of the flower color trait. So, a plant with the genotype FF or Ff will have purple flowers.
A recessive allele causes its version of the trait to appear only when the organism does not have any dominant alleles for the gene. In pea plants, the f allele, which causes white flowers, is recessive to the F allele. A pea plant with only f alleles will have the f allele's version of the flower color trait. So, a plant with the genotype ff will have white flowers.

Question:
Based on this information, what is this plant's phenotype for the pea shape trait?

0. round peas
1. wrinkled peas

[Assistant]
The pea plant's genotype for the pea shape gene is ee. The pea plant's genotype of ee has only e alleles. The e allele is for wrinkled peas. So, the pea plant's phenotype for the pea shape trait must be wrinkled peas.
To check this answer, consider whether the pea plant's alleles are dominant or recessive. The allele for round peas (E) is dominant over the allele for wrinkled peas (e). This means E is a dominant allele, and e is a recessive allele.
The pea plant's genotype of ee has only recessive alleles. An organism with only recessive alleles for a gene will have the recessive allele's version of the trait. So, the pea plant's phenotype for the pea shape trait must be wrinkled peas.
Therefore my final answer is: 1

Matter is made of tiny particles called atoms. Atoms are always moving.
The energy of moving atoms is called thermal energy. The total amount of thermal energy in matter depends on three things: the type of matter, the amount of matter, and how fast the atoms are moving.
Temperature measures how hot or cold matter is. If the atoms in matter slow down, the temperature goes down. The matter now has both less thermal energy and a lower temperature.
What happens if the amount of matter changes? A 1-kilogram brick at 70F has half as much thermal energy as a 2-kilogram brick at 70F. The two bricks have the same temperature, but the smaller brick has half as many atoms. So, it has half as much thermal energy.

Question:

Gravitational potential energy is stored between any two objects. So, for every object on or near Earth, there is gravitational potential energy stored between the object and Earth.
The amount of gravitational potential energy stored between an object and Earth depends on the mass of the object. The amount of gravitational potential energy also depends on the distance between the object and the center of Earth. This distance increases when the object moves higher and decreases when the object moves lower.
If the distance between an object and the center of Earth changes, the gravitational potential energy stored between the object and Earth will change. The table below shows how this change can happen.
When an object's mass stays the same and its distance from the center of Earth... | Gravitational potential energy stored between the object and Earth...
increases | increases
decreases | decreases

All organisms have pieces of hereditary material called genes, which are passed from parents to offspring. Genes contain instructions for building the parts of an organism. An organism's genes affect its observable traits, including its appearance, its behavior, and which diseases it may have. Genes may have different alleles, or forms, that can cause different versions of a trait.
For example, flower color is a trait in pea plants. The gene for this trait has two possible alleles. Each allele is represented by an uppercase or lowercase letter. The allele F is for purple flowers, and the allele f is for white flowers. Each pea plant has two alleles for the flower color geneone allele inherited from each parent.
An organism's genotype for a gene is its combination of alleles for that gene. So, a pea plant may have a genotype of FF, Ff, or ff for the flower color gene.
An organism's phenotype for a trait is its observable version of that trait, which depends on the organism's combination of alleles. A pea plant may have a phenotype of purple flowers or white flowers for the flower color trait.

Question:
Based on this information, what is this rose plant's phenotype for the thorns trait?

0. RR
1. having thorns

[Assistant]

Question:
Which of these things did the Thirteen Colonies have at the start of the Revolutionary War?

0. their own national bank
1. their own national navy
2. none of the above
3. their own national government

[Assistant]
At the start of the Revolutionary War, the colonies were still ruled by Great Britain. They were not a separate country. So, they did not have many of the things most countries have.
No national government: The Thirteen Colonies had no way to write laws together. They also had no way to collect taxes to support a war.
No national navy: The Thirteen Colonies did not have a navy. The colonists had never fought a war at sea.
No national bank: Wars are expensive. A national bank can help a country raise money by borrowing from its people or other countries. Without a national bank, the Thirteen Colonies had no easy way to pay for a war.

Poetry is a special kind of writing. It has many elements that make it different from ordinary writing. Knowing these elements can help you talk about poetry, understand it better, and enjoy it more.
A poem rhymes when it has a pattern of words that end in the same sound.
End rhyme is when the rhymes appear at the end of a poem's lines.
Little Betty Blue,
Lost her holiday shoe.
From Mother Goose
Internal rhyme is when at least one of the rhyming words appears inside the poem's lines.
Sweet dreams of pleasant streams.
From William Blake, "A Cradle Song"
Rhythm is the pattern of strong and weak syllables, or stress, in a poem. You can recognize rhythm in a poem by listening to how it sounds. Poems with regular rhythm have a beat, like in music.
He watches from his mountain walls,
And like a thunderbolt he falls.
From Alfred, Lord Tennyson, "The Eagle"
The syllables in bold are strong. We say them with more force than the other syllables. In this poem, every weak syllable is followed by a strong syllable. Each line sounds like da-DUM da-DUM da-DUM da-DUM. To better hear the rhythm, try reading it aloud while clapping on each strong syllable.
Free verse is when a poem has neither a regular rhythm nor a rhyme pattern.
The old bridge has a wrinkled face.
He bends his back
For us to go over.
From Hilda Conkling, "The Old Bridge"
The syllables in bold are strong. You can see this poem does not have a regular rhythm. It also doesn't have a rhyme pattern.
Repetition is when words, phrases, or whole lines are repeated.
The dainty flying squirrel
In vest of shining white,
In coat of silver gray,
And vest of shining white.
Adapted from Mary E. Burt, "The Flying Squirrel"
Alliteration is when beginning consonant sounds are repeated in words that are close together.
Where the wild men watched and waited
Wolves in the forest, and bears in the bush.
From Bayard Taylor, "A Night with a Wolf"
Onomatopoeia is when language sounds like what it talks about.
Sometimes the onomatopoeia uses made-up words:
Tlot-tlot! tlot-tlot! Had they heard it? The horse hoofs ringing clear.
From Alfred Noyes, "The Highwayman"
Sometimes the onomatopoeia uses real words:
Hark! the honey bee is humming.
From Mary Howitt, "The Voice of Spring"

speeding up,
slowing down, or
changing direction.

Every substance around you is made of one or more chemical elements, or types of atoms. Substances that are made of only one chemical element are elementary substances. Substances that are made of two or more chemical elements bonded together are compounds.
Every chemical element is represented by its own symbol. For some elements, the symbol is one capital letter. For other elements, the symbol is one capital letter and one lowercase letter. For example, the symbol for the element fluorine is F, and the symbol for the element beryllium is Be.
The symbol for each element in a substance is shown in the substance's chemical formula.
An elementary substance is represented by a chemical formula that contains only one symbol.
The symbol may be followed by a subscript. A subscript is text that is smaller and placed lower than the normal line of text. A subscript is included when the atoms in the elementary substance are bonded to form molecules. The subscript tells you the number of atoms in each molecule.
For example, the chemical formula for the elementary substance oxygen is O2. The formula has a subscript of 2. This subscript tells you that there are two atoms in the molecule represented by this chemical formula.
The chemical element represented by the symbol O is also called oxygen. So, the formula O2 tells you that each molecule of O2 contains two oxygen atoms.
A compound is represented by a chemical formula that contains multiple symbols.
For example, in the compound beryllium fluoride, there is one beryllium atom for every two fluorine atoms. This combination is shown in the compound's chemical formula, BeF2. In the formula, the symbol Be represents one beryllium atom. The symbol F followed by the subscript 2 represents two fluorine atoms.

Question:
Complete the statement.
Titanium is ().

0. a compound
1. an elementary substance

[Assistant]
You can tell whether titanium is an elementary substance or a compound by counting the number of symbols in its chemical formula. A symbol contains either one capital letter or a capital letter followed by one or two lowercase letters.
The chemical formula for titanium is Ti. This formula contains one symbol: Ti. So, the formula tells you that titanium is made of one chemical element.
Substances made of only one chemical element are elementary substances. So, titanium is an elementary substance.
