A student conducted an experiment to see how far a ball rolled down a ramp. Which tool would BEST measure the distance the ball rolled?

• Balance Scale

• Graduated cylinder

• Meter stick

• Thermometer

A student wanted to determine how force and mass affect a toy car. She gathered a toy car, books, straight tracks, meter sticks, and used a flat surface to conduct her experiment. She first created a ramp that was 40cm tall using 3 books. She placed the toy car at the top of the track. She tested how far car 1 traveled. She recorded her results. Next, she placed a 4th book on the stack and it measured 50 cm tall. She repeated the experiment again and recorded her results. What is the student’s testable question?

• How does changing the height of a ramp affect how far a toy car travels?

• How many books were used in this student’s toy car experiment?

• How does using a straight track affect how far a toy car travels?

• How does using a straight track affect how high the ramp is in the system?

Students investigate how the sky during the day appears to change over a period of sixty days. Which method would BEST help the students complete their project?

• Have a different student observe the sky each day

• Use several telescopes to get a complete view of the sky.

• Observe the same part of the sky each day over the time period.

• Observe different parts of the sky on the first day and the last day.

A group of scientists are studying the effect social media has on fifth graders. Before starting the investigation, the scientists predicted that if 5th graders are exposed to several hours of social media a day then they will have difficulty concentrating in school. Which term BEST describes the statement made by a group of scientists?

• Constant

• Data

• Hypothesis

• Variable

To test which size toy car will roll down a hill the fastest, all the variables would have to be the same EXCEPT--

• How big the toy car is

• The surface of the hill

• The height of the hill

• How hard the car is pushed
