Students rolled different objects down a ramp and recorded their speed in meters per second (m/s).
Which object traveled the slowest? How do you know?
Which object traveled the fastest? How do you know?
Based on the graph, what is the relationship between the speed of an object and the amount of time it took to roll down the ramp?
Students mixed different chemicals and recorded the temperature change in degrees Celsius (°C).
Which reaction caused the greatest temperature increase? How do you know?
Which reaction caused the greatest temperature decrease? How do you know?
Why do some reactions cause temperature increases while others cause decreases?
The graph shows how far different vehicles traveled in 5 hours.
Which vehicle went the farthest distance?
