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 mountain bikers. Which mountain biker was moving at a higher speed?

0. a mountain biker who moved 165kilometers in 5hours
1. a mountain biker who moved 135kilometers in 5hours

[Assistant]
Look at the distance each mountain biker moved and the time it took to move that distance.
One mountain biker moved 165 kilometers in 5 hours.
The other mountain biker moved 135 kilometers in 5 hours.
Notice that each mountain biker spent the same amount of time moving. The mountain biker who moved 165 kilometers moved a farther distance in that time. So, that mountain biker must have moved at a higher speed.
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.
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 Wanda's phenotype for the body color trait?

0. a gray body
1. a golden body

[Assistant]
Wanda's genotype for the body color gene is bb. Wanda's genotype of bb has only b alleles. The b allele is for a golden body. So, Wanda's phenotype for the body color trait must be a golden body.
To check this answer, consider whether Wanda's alleles are dominant or recessive. The allele for a gray body (B) is dominant over the allele for a golden body (b). This means B is a dominant allele, and b is a recessive allele.
Wanda's genotype of bb has only recessive alleles. An organism with only recessive alleles for a gene will have the recessive allele's version of the trait. So, Wanda's phenotype for the body color trait must be a golden body.
Therefore my final answer is: 1

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.

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. Native gold is a solid. It is a pure substance.
1. A turtle shell is made by a living thing. It is a solid.

[Assistant]
Compare the properties of each substance to the properties of minerals. Select the substance whose properties do not match those of minerals.
A turtle shell is made by a living thing. But minerals are not made by living things.
So, a turtle shell is not a mineral.
Native gold is a mineral.
Magnetite is a mineral.

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:
The students start rolling their backpacks at the same speed. Which backpack is pulled with a larger force?

0. a backpack carrying 5 pounds
1. a backpack carrying 7 pounds

[Assistant]
Look for the backpack that is heavier.
A backpack carrying 7 pounds is heavier than a backpack carrying 5 pounds. So, the backpack carrying 7 pounds needs to be pulled with a larger force to start rolling at the same speed as the other backpack.
Therefore my final answer is: 1


[User]
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 objects moving for the same amount of time. The object that is moving the slowest will go the shortest distance in that time. It is moving at the lowest speed.

Question:
Compare the motion of three bicycles. Which bicycle was moving at the lowest speed?

0. a bicycle that moved 245kilometers east in 5hours
1. a bicycle that moved 70kilometers north in 5hours
2. a bicycle that moved 230kilometers north in 5hours

[Assistant]
Look at the distance each bicycle moved and the time it took to move that distance. The direction each bicycle moved does not affect its speed.
Notice that each bicycle moved for 5 hours. The bicycle that moved 70 kilometers moved the shortest distance in that time. So, that bicycle must have moved at the lowest speed.

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 60 minutes in 1 hour. So, 1 minute is much less than 1 hour.

A force is a push or a pull that acts on an object. Every force has a direction and a magnitude, or strength. If two forces act on an object in opposite directions, the forces are called opposing forces.
When opposing forces have the same magnitude, they are balanced. If all the forces on an object are balanced, there is no net force on the object.
When opposing forces have different magnitudes, the forces are unbalanced. If any forces on an object are unbalanced, there is a net force on the object.

Question:
Assume all other forces on Oscar are balanced. Which statement describes the forces on Oscar?

0. The forces are unbalanced, so there is a net force on Oscar.
1. The forces are balanced, so there is no net force on Oscar.

[Assistant]
To determine if there is a net force on Oscar, look at the forces:
Earth's gravity is pulling Oscar down with a force of 400 N.
The diving board is pushing Oscar up with a force of 400 N.
The forces are in opposite directions, and the forces have the same magnitude: 400 N. This means that the forces are balanced, so there is no net force on Oscar.

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 muskmelon plant's genotype for the fruit taste gene?

0. sour fruit
1. Ff

[Assistant]

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 the sled's mass did not change.
The gravitational potential energy stored between the sled and Earth () as Elizabeth rode down the hill.

0. decreased
1. stayed the same
2. increased

[Assistant]
Think about how the distance between the sled and the center of Earth changed.
The bottom of the hill was lower than the point where Elizabeth started sledding. As Elizabeth rode toward the bottom of the hill, the distance between the sled and the center of Earth decreased. So, the gravitational potential energy stored between the sled and Earth decreased as Elizabeth rode down the hill.

As the diagram shows, there are 8 fluid ounces in 1 cup and 16 cups in 1 gallon. So, 1 fluid ounce is less than 1 cup and much less than 1 gallon.
A glass of milk has a volume of about 8 fluid ounces, or 1 cup. A jug of milk has a volume of 1 gallon.

Question:
What is the volume of a water balloon?

0. 15 cups
1. 15 fluid ounces
2. 15 gallons

[Assistant]
The best estimate for the volume of a water balloon is 15 fluid ounces.

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:
Which egg has less thermal energy?

0. the colder egg
1. the hotter egg

[Assistant]
The two eggs are made of the same material and have the same mass. So, the colder egg has less thermal energy.
Therefore my final answer is: 0

Organisms, including people, have both inherited and acquired traits. Inherited and acquired traits are gained in different ways.
Inherited traits are passed down from biological parents to their offspring through genes. Genes are pieces of hereditary material that contain the instructions that affect inherited traits. Offspring receive their genes, and therefore gain their inherited traits, from their biological 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. Parents do not pass acquired traits down to their offspring.

Question:
What information supports the conclusion that Jenna inherited this trait?

0. Jenna's biological parents have red hair. Jenna also has red hair.
1. Jenna's neighbor also has straight hair.
2. Jenna's biological mother often wears her straight hair in a ponytail.

[Assistant] Therefore my final answer is: 2

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. Molasses is made by humans. It is not a pure substance.
1. Pyrite is formed in nature. It is a pure substance.
2. Sphalerite is formed in nature. It is a pure substance.

[Assistant]
Compare the properties of each substance to the properties of minerals. Select the substance whose properties do not match those of minerals.
Pyrite is a mineral.
Sphalerite is a mineral.
Molasses is made by humans. But minerals are not made by living things.
Molasses is not a pure substance. But all minerals are pure substances.
So, molasses is not a mineral.
Therefore my final answer is: 0

Measurements are written with both a number and a unit. The unit comes after the number. The unit shows what the number means.
Mass is a measurement of how much matter something contains.
There are many different units of mass. When you are using customary units, mass may be written with units of ounces, pounds, or tons.
There are 16 ounces in 1 pound and 2,000 pounds in 1 ton.
So, 1 ounce is less than 1 pound and much less than 1 ton.
A slice of bread has a mass of about 1 ounce, while a can of beans has a mass of about 1 pound. A small car has a mass of about 1 ton.

Question:
What is the mass of an ear of corn?

0. 15 tons
1. 15 ounces

Scientists sort animals with similar traits into groups. This is called classification. Classification helps scientists learn about how animals live.
How do scientists classify animals? First, they make observations about an animal. Scientists observe the animal's traits, including its body parts and behavior. Then, scientists compare the animal's traits to other animals' traits. Scientists classify animals with similar traits into a group.

Question:
Select the one animal that has all of the mollusk traits listed above.

0. Earthworms live in soil and have no limbs. Their bodies are soft, cylindrical, and made up of many segments.
1. Banana slugs have a soft body with a flat underside called the foot. Slugs use their muscular foot to move. Banana slugs also have small teeth on their tongue! These file-like teeth help banana slugs eat leaves and dead plants.

[Assistant]
To decide if an animal is part of a group, look at the traits of the group.
Mollusks have the following traits:
They have a soft body.
They have a muscular foot or tentacles.
Compare each animal's traits to the group's traits. Select the animal with traits similar to the group's traits.
A banana slug has the following traits:
It has a soft body.
It has a muscular foot.
A banana slug has the traits of a mollusk. A banana slug is a mollusk.
An earthworm has the following traits:
It has a soft, cylindrical body.
It has no limbs.
It is made up of segments.
An earthworm does not have all of the traits of a mollusk. An earthworm is a segmented worm.
Therefore my final answer is: 1


[User]
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 Chloe's phenotype for the ear type trait?

0. curled ears
1. straight ears

[Assistant]
Chloe's genotype for the ear type gene is EE. Chloe's genotype of EE has only E allelles. The E allele is for curled ears. So, Chloe's phenotype for the ear type trait must be curled ears.
To check this answer, consider whether Chloe's alleles are dominant or recessive. The allele for straight ears (e) is recessive to the allele for curled ears (E). This means E is a dominant allele, and e is a recessive allele.
Chloe's genotype of EE 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, Chloe's phenotype for the ear type trait must be curled ears.
Therefore my final answer is: 0

Vertebrates and invertebrates are both groups of animals.
A vertebrate has a backbone. The backbone is made of many bones in an animal's back. A vertebrate's backbone helps connect the different parts of its body. In the drawings below, each vertebrate's backbone is colored orange.
An invertebrate does not have a backbone. In fact, invertebrates do not have any bones! Some invertebrates have an outer cover on their body called an exoskeleton. Other invertebrates have a soft body.
