What is he most likely testing when he drops the ball into the water?
A. whether the foam ball will float
B. whether the foam ball is waterproof
C. whether the foam ball will soften the landing
D. whether the foam ball will bounce when it hits the water
C. whether the foam ball will soften the landing

Is taller than trees,
Up, up it goes,
And yet never grows?

Ian and Luis designed and made two model cars, one green and one yellow. They released both cars at the top of a ramp. They measured how far each car traveled from the bottom of the ramp until stopping. The table shows their results.

What is the next step that Ian and Luis should take?
A. redesign the yellow car
B. communicate their results
C. test the cars two more times
D. conclude that the green car goes farther
C. test the cars two more times

A student is designing a new model airplane. The student measures the speed of each model airplane in meters per second (m/s).

To develop the fastest design, what should the student do next?
A. use design 1 because it had the fastest speed
B. use design 3 because it had the fastest speed
C. choose another design that will give better results
D. combine elements from design 1 and design 3 and test again
D. combine elements from design 1 and design 3 and test again

Said the first eye,
"But in low place,
Not in high place."

A new design for a roller coaster protects the coaster by stopping it against a large spring. To evaluate the safety of this solution, researchers build a model coaster and run it along the track. What is the most important thing they should observe during this test?
A. how fast the model travels
B. how much the spring stretches
C. whether the model is damaged
D. whether the spring looks acceptable
C. whether the model is damaged
It cannot be seen, cannot be felt,
Cannot be heard, cannot be smelt.
It lies behind stars and under hills,
And empty holes it fills.
It comes first and follows after,
Ends life, kills laughter.
