A force is a push or a pull.
A force can make an object start moving or stop an object that is moving. A force can also make an object speed up, slow down, or change direction.
Forces can be different sizes.
Think about trying to move a heavy object and a light object. Imagine you want to move them at the same speed. You will need to use a larger force to move the heavy object.

Question:
Marco starts to pull the wagon across the yard. To move the wagon at the same speed each time, which friend does Marco need to pull with a larger force?

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 move faster, the temperature goes up. The matter now has both more thermal energy and a higher temperature.
What happens if the amount of matter changes? A 2-kilogram brick at 70F has twice as much thermal energy as a 1-kilogram brick at 70F. The two bricks have the same temperature, but the larger brick has twice as many atoms. So, it has twice as much thermal energy.

Solid, liquid, and gas are states of matter. Matter is anything that takes up space. Matter can come in different states, or forms.
When matter is a solid, it has a definite volume and a definite shape. So, a solid has a size and shape of its own.
Some solids can be easily folded, bent, or broken. A piece of paper is a solid. Also, some solids are very small. A grain of sand is a solid.
When matter is a liquid, it has a definite volume but not a definite shape. So, a liquid has a size of its own, but it does not have a shape of its own. Think about pouring juice from a bottle into a cup. The juice still takes up the same amount of space, but it takes the shape of the bottle.
Some liquids do not pour as easily as others. Honey and milk are both liquids. But pouring honey takes more time than pouring milk.
When matter is a gas, it does not have a definite volume or a definite shape. A gas expands, or gets bigger, until it completely fills a space. A gas can also get smaller if it is squeezed into a smaller space.
Many gases are invisible. Air is a gas.

Question:

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.
Benzene is ().

0. an elementary substance

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 kilometer.
Time tells you how long the object has spent moving. One unit used to measure time is the hour.
Think about two objects moving for the same amount of time. The object that is moving faster will go a farther distance in that time. It is moving at a higher speed.

Question:
Compare the motion of two birds. Which bird was moving at a higher speed?

0. a bird that moved 45kilometers in 10hours
1. a bird that moved 25kilometers in 10hours

[Assistant]

There is a surplus if there is too much for sale at a given price.
There is a shortage if there is not enough for sale at a given price.
Surpluses and shortages usually happen when people who are selling goods or services charge too much or too little.
When the price is too high, consumers will not want to buy much of the good or service. The quantity demanded will be less than the quantity supplied. So, there will be a surplus.
When the price is too low, too many consumers will want to buy the good or service. The quantity demanded will be more than the quantity supplied. So, there will be a shortage.

Question:
Is there a surplus or a shortage of washing machines?

0. shortage
1. surplus

[Assistant]
At the current price, there are not enough washing machines for sale. There are 20 machines for sale, but 30 people want to buy one.

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 Felicia's phenotype for the fur type trait?

0. ff

Organisms, including people, have both inherited and acquired traits. Inherited and acquired traits are gained in different ways.
Inherited traits are passed down through families. Children gain these traits from their parents. Inherited traits do not need to be learned.
Acquired traits are gained during a person's life. Some acquired traits, such as riding a bicycle, are gained by learning. Other acquired traits, such as scars, are caused by the environment. Children do not inherit their parents' acquired traits.

Question:
Is the following trait inherited or acquired?
Chloe has a scar on her left elbow.

0. acquired
1. inherited

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 fish's phenotype for the body color trait?

0. a greenish-brown body
1. a pink body

[Assistant]
The Nile tilapia fish's genotype for the body color gene is BB. The Nile tilapia fish's genotype of BB has only B allelles. The B allele is for a greenish-brown body. So, the Nile tilapia fish's phenotype for the body color trait must be a greenish-brown body.
To check this answer, consider whether the Nile tilapia fish's alleles are dominant or recessive. The allele for a greenish-brown body (B) is dominant over the allele for a pink body (b). This means B is a dominant allele, and b is a recessive allele.
The Nile tilapia fish's genotype of BB has two dominant alleles. An organism with at least one dominant allele for a gene will have the dominant allele's version of the trait. So, the Nile tilapia fish's phenotype for the body color trait must be a greenish-brown body.
Therefore my final answer is: 0

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
stays the same | stays the same

Question:
Complete the statement. Assume that Tony's mass did not change.
The gravitational potential energy stored between Tony and Earth () as he rode the escalator.

Measurements are written with both a number and a unit. The unit comes after the number. The unit shows what the number means.
Imagine being told that the bus leaves in 7. You might be thinking, 7 what? Does the bus leave in 7 minutes? 7 seconds?
The number 7 on its own does not give you much information about when the bus is leaving. That is because the units are missing.
Time is usually measured in units of seconds, minutes, or hours. It takes about 1 second to sneeze and 1 minute to get dressed in the morning. It takes about 1 hour to bake a pie in the oven.
There are 60 seconds in 1 minute. So, 1 second is much less than 1 minute.

There are four kinds of sentences.
A declarative sentence is a statement, and it always ends with a period.
The nurse told Mr. Abrams to roll up his sleeve so that she could check his blood pressure.
An interrogative sentence is a question, and it always ends with a question mark.
Do you have any plans for the upcoming weekend?
An imperative sentence is a command. It makes a request or tells someone to do something, and it usually ends with a period. If the command shows strong feeling, it ends with an exclamation point.
For this assignment, use references to support your claims.
Don't drive so quickly in the construction zone!
An exclamatory sentence is like a statement, but it shows surprise or strong feeling. An exclamatory sentence always ends with an exclamation point.

Ben usually wears his heavy coat in the winter.
A compound sentence is made up of two independent clauses joined by a coordinating conjunction such as and, but, or, or so.
We saw the flash of lightning, and seconds later we heard a rumble of thunder.
A complex sentence is made up of an independent clause and a dependent clause. The dependent clause in a complex sentence usually begins with a subordinating conjunction or relative pronoun. Subordinating conjunctions include after, although, as, because, before, if, since, unless, until, when, and while. Relative pronouns include that, which, who, whom, or whose.
If she ever gets the chance, Terri would love to visit the Egyptian pyramids.
During his trip to Italy, Tony visited the Trevi Fountain, which is in Rome.
A compound-complex sentence is made up of two or more independent clauses and one or more dependent clauses.
After Samantha left work, she stopped at the bank, and then she went to the gym.
Sometimes a dependent clause in a complex or compound-complex sentence can interrupt an independent clause.

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 cucumber plant's genotype for the fruit sheen gene?

0. dull fruit
1. Ff

[Assistant]
An organism's genotype for a gene is its combination of alleles for that gene. The cucumber plant has one allele for dull fruit (F) and one allele for glossy fruit (f). So, the plant's genotype for the fruit sheen gene is Ff.
Therefore my final answer is: 1

Informal writing is typically used in casual situations or when communicating with someone you know well. Informal language often expresses familiarity and tends to sound more like speech. It uses more conversational language, such as slang, idioms, abbreviations, imprecise language, and contractions.
Formal writing is typically used in academic and business writing or when writing directly to an authority figure. It tends to be more courteous and impersonal, avoiding overly familiar or conversational language.
Compare the following sentences.
Informal: Yeah, ostriches can't fly, but I think they're awesome.
More formal: Ostriches may be flightless, but they're remarkable runners.
Most formal: Though flightless, ostriches are remarkable runners.

Organisms, including people, have both inherited and acquired traits. Inherited and acquired traits are gained in different ways.
Inherited traits are passed down through families. Children gain these traits from their parents. Inherited traits do not need to be learned.
Acquired traits are gained during a person's life. Some acquired traits, such as riding a bicycle, are gained by learning. Other acquired traits, such as scars, are caused by the environment. Children do not inherit their parents' acquired traits.

Question:
Is the following trait inherited or acquired?
Beth has a scar on her left hand.

A chemical change occurs when new substances are formed from existing substances. This process is called a chemical reaction.
In a chemical reaction, one or more substances change into one or more different substances. During the reaction, the atoms of the original substances are rearranged to form other substances.
The original substances in a chemical reaction are called reactants. These substances react, or go through a chemical change.
The substances that are formed in a chemical reaction are called products. These substances are produced by the chemical reaction.
So, in a chemical reaction, reactants go through a chemical change to form products.

Question:
Complete the sentence.
In this chemical reaction, nitrogen is a ().

0. product
1. reactant

[Assistant]
Read the underlined text carefully. Look for information about what happens to nitrogen in this chemical reaction.
Did you know that lightning helps provide nutrients to plants on Earth? When lightning strikes, the air around it becomes extremely hot. This leads to the formation of nitric oxide from the nitrogen and oxygen gases in the air. Nitric oxide plays an important role in helping plants grow.
The underlined text tells you that when nitrogen and oxygen combine, nitric oxide is formed. When nitrogen and oxygen react, or go through a chemical change, their atoms are rearranged to form nitric oxide. Because nitrogen reacts in this chemical reaction, nitrogen is a reactant.

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. Sphalerite is a pure substance. It is not made by living things.
1. Steel is made in a factory. It is not a pure substance.
2. Pyrite is formed in nature. It is not made by living things.

[Assistant]
Compare the properties of each substance to the properties of minerals. Select the substance whose properties do not match those of minerals.
Steel is made in a factory. But all minerals are formed in nature.
Steel is not a pure substance. But all minerals are pure substances.
So, steel is not a mineral.
Pyrite is a mineral.
Sphalerite is a mineral.
