Questions 1-6
A student sets up the cardboard tube shown on page 3. The student holds the tube at an angle. The students drops a ball into each hole, then measures how fast the ball travels when it comes out of the tube. Dropping the ball into which hold will cause the ball to travel the fastest?
What is B. Hole 1, because the ball will have the most potential energy.
A science quote from an article about land use is shown.
"Science studies show that when people build more roads, parking lots, sidewalks, and rooftops, there is more storm water runoff. This can cause more flooding and erosion." Which human activity is the author talking about in this quote?
What is D. building cities.

What is M. both locations are on the same line of longitude
Students classified organisms based on their roles in a forect ecosystem. The data table on page 23 shows how the students classified the organisms of a forest ecosystem. Which TWO energy flows are CORRECT based on the students' classifications?
What is P. plant--->deer
What is S. sun --->plant
Students choose playground activities to demonstrate energy transfer. Which activity shows a transfer of potential energy to kinetic energy?
What is A. sliding from the top of a slide
The graph on page 6 shows population growth and water usage for the world. Which statement is correct based on the data shown?
What is D. The amount of water used is higher when the human population is higher.
The diagram on page 11 shows a model of the different layers inside Earth. Which TWO statements BEST compare the crust to the rest of the layers?
What is M. The crust surrounds all the other layers and is solid. and R. The crust is the thinnest layer and is solid.
On a forest field trip, a student is assigned a list of observations to make. One observation the student looks for is evidenec of mechanical weathering. Which activity would allow the student to check mechanical weathering off the list?
What is D. a stone becoming smooth in a flowing riverbed
The map on the left on page 22 shows the Andes mountain range in South America. The map on the right shows the Himalayan mountain range in India. The mountain ranges in these maps are evidence that mountain ranges...
What is A. form at the border of two tectonic plates
Shadows of objects on Earth change throughout the day. This occurs because Earth rotates. Which TWO models on page 32 show how the sun causes shadows to appear on Earth?
What is P. and T.
Which THREE statements correctly describe materials plants need?
What is M. Plants need sunlight to grow.
What is P. Plants need water to grow.
What is S. Plants need carbon dioxide to photosynthesize.
The diagram on page 13 shows a V-shaped valley. The valley did not exist thousands of years ago. This valley is MOST LIKELY the result of...
A student states that plants need sunlight to grow. The student plans an investigation to help support the argument with evidence. The diagrams on page 18 represent four different setups. Which setup will give the MOST evidence to support the student's claim?
What is B.
A photograph of a river delta is shown on page 25. Which statement correctly describes the delta in the photograph?
What is P. Deposition is causing the delta to become bigger over time.
The graph on page 34 shows the thickness of Earth's layers. Which table correctly identifies Earth's layers from thinnest to thickest?
What is A. Crust ---> Inner Core ---> Outer Core
---> Mantle
The table on page 8 shows typical temperatures in a gray wolf habitat. Which of these BEST describes a wat that gray wolves adapt to survive the changing temperatures?
What is A. Wolves develop a heavy coat in the fall and shed it in the spring.
A simplified food web of a marsh ecosystem is shown on page 12. Which organisms get energy from crickets?
What is C. shrews and frogs
The table on page 19 shows information about some energy resources. 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?
What is P. Natural gas is a fossil fuel that must be removed from under the ground.
What is R. The largest amount of electricity is produced from nonrenewable resources.
What is S. Getting coal from beneath Earth's surface destroys the ecosystem in that location.
Some animals protect coral reefs while others harm them. The Crown of Thorns Starfish came to a certain coral reef in the Pacific Ocean in 2015. The graph on page 26 shows the size of the reef over time. Which statement about the size of the reef is supported by the data in the graph?
What is B. the starfish made the coral reef smaller from 2015 to 2018.

What is S. sun
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 on page 9. Which conclusion is supported by the data?
What is P. The ball had the least energy on roll 4.
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?
What is D. the water used by plants on the banks of the stream would be reduced as the stream water moves more quickly through the ecosystem.
Many objects produce thermal energy. Students want to sort the objects into two groups on page 20. Which question should the students ask to decide which object to put into Group 2?
What is C. can the object produce thermal energy without being plugged in?
Students dropped a ball of dough from different heights and timed how long it took the ball to fall to the floor. They then drew the shape of the dough after it hit the floor. Their data are in the table on page 27. Based on the data collected, which TWO conclusions can students make about the speed and energy of the dough when it hit the floor?
