The table shows typical temperatures in a gray wolf habitat. Which of these best describes a way that gray wolves adapt to survive the changing temperatures?

• Wolves develop a heavy coat in the fall and shed it in the spring.

• Each wolf's howl sounds different from the others

• A wolf pack works together to find food in the fall.

• Wolves are most active at sunrise and sunset.

The diagram shown is a model of the different layers inside Earth. Which two statements best compare the crust to the rest of the layers?

• The crust surrounds all the other layers and is solid.

• The crust is the innermost layer and is liquid.

• The crust is the thinnest layer and is solid.

• The crust is the outermost layer and is liquid.

• The crust is the thickest layer and is solid.

A beaver is a mammal that builds its home in a stream or river. The beaver’s home is called a lodge. The beaver builds the lodge in the middle of a pond it creates by building dams in the stream. The picture shows a model of a stream ecosystem with two beaver dams and a beaver lodge. Based on the model, what would most likely happen to the ecosystem if the beavers and their dams were removed?

• The trees would have more water to use as the stream water moves more slowly through the ecosystem.

• The stream would be wider and deeper as the stream water moves more slowly through the ecosystem.

• The banks of the stream would have less erosion as the stream water moves more quickly through the ecosystem.

• The water used by plants on the banks of the stream would be reduced as the stream water moves more quickly through the ecosystem.

A student saw a rainbow outside after school. The next day the student decided to model how rainbows form. The student shines white light through a glass prism and sees how the light splits up into many colors. Which two ways does the student’s model need to be changed to better show how rainbows are formed?

• The prism should be as high in the air as rainbows are.

• The model needs to be outside because rainbows only form outside.

• The prism should have a round shape because raindrops are round.

• The prism should be made of water instead of glass because rain is made of water.

• Sunlight should be used instead of white light because sunlight and white light are made of different things.

After observing the table, students conclude that renewable resources of energy should be used more to have cleaner air. Which three explanations support this conclusion?

• More wind energy produced means more pollution.

• Natural gas is a fossil fuel that must be removed from under the ground.

• The largest amount of electricity is produced from nonrenewable resources.

• Getting coal from beneath Earth’s surface destroys the ecosystem in that location.

• Solar cells absorb energy that would normally be used by plants to make oxygen.

Many objects produce thermal energy. Students want to sort the objects into two groups: Group 1: Objects that use electricity to produce thermal energy. Group 2: Objects that use stored energy to produce thermal energy. Which question should the students ask to decide which object to put into Group 2?

• How much thermal energy does the object produce?

• How do people use the thermal energy produced by the object?

• Can the object produce thermal energy without being plugged in?

• Can the thermal energy produced by the object be changed into another form of energy?

Students took turns rolling a ball across a classroom floor. A sensor measured the speed of the ball at the one-meter mark. The students recorded the speed in a data table. Which conclusion is supported by the data?

• The ball had the most energy on roll 1.

• The ball had the least energy on roll 4.

• The ball had less energy on roll 1 than on roll 2.

• The ball had more energy on roll 2 than on roll 3.
