Renee rolls a steel ball down a ramp. She conducts multiple trials by releasing the ball from varying heights on the ramp. For each trial, she measures and records the release height of the ball and the distance the ball travels away from the ramp before falling to the ground. The figure below shows the experiment.
In this experiment, which variable is the independent variable?
distance traveled by the ball
path of ball once it leaves the ramp
height from which the ball is released
time it takes the ball to hit the ground
When planning an experiment, a scientist must first choose a question to investigate. Renata conducts the experiment shown below. In the experiment, she changes the release height of the steel ball and measures the distance the ball travels from the ramp before falling to the ground.
Based on this evidence, which question is Renata investigating?
How much force does the ball exert when it strikes the floor?
How is the speed of the ball affected by the release height from a ramp?
How does the release height of a ball on a ramp affect the distance it travels from the ramp before falling to the floor?
How does the release height of a ball on a ramp affect the amount of time that passes before the ball hits the floor?
Cindy predicts that plastic foam insulates cold drinks better than metal or ceramic materials do. To test the hypothesis, she fills cups made from these materials with equal amounts of cold water.

Which of these conditions must be the same for this experiment to be valid?
the thermometer that is in each cup

Tamar is talking about evolution with a friend. The friend says, “It’s just a theory, so I don’t believe it. When they prove it and it becomes the law of evolution, then maybe I’ll change my mind.”
Which of these possible replies best describes scientific principles or the work of scientists?
Scientific theories do not become scientific laws; they are explanations for natural phenomena based on evidence.
Science always finds the right answer; the answers that scientists and researchers discover never change.
He should be wary of science because it is based on research and evidence, not bias and opinion.
Scientists take each other at their word regarding experimental results, and the public should, too.

Many insects, such as mosquitoes and dragonflies, spend their juvenile stage as aquatic larvae before becoming winged and airborne adults. Most years, these insects are extremely abundant in the Arctic tundra in summer. What might account for this?
Adult insects spend the long Arctic winter laying thousands of eggs under the ice of frozen ponds.
Many insects migrate long distances to take advantage of good breeding areas in the tundra.
Pools of water which make good breeding areas are plentiful in summer as the permafrost melts.
Summer rains in the Arctic tundra replenish breeding ponds that dried up during the winter.
