Day 20 Period 5 Ball on Ramp Lab

Day 20 Period 5 Ball on Ramp Lab: Acceleration

Warm Up • Calculate the average speed of a dog running through a field if he is covering 23. 7 meters in 54 seconds. Distance (m) a. Write the equation in y = mx +b form b. Sketch what that would look like on a distance vs. time graph Time (seconds)

Agenda • Ball on Ramp Lab Set Up • Lab

Learning Target

Ball on Ramp Experiment • Wild Guess: How long will it take a ball bearing to roll down TWO of these tubes at this angle? Wild Guess Inquiry to Determine Pattern Making Sense of the Pattern Through Consensus Data Informed Prediction • Research Question: How does the distance a ball rolls affect the time it will roll?

Variables • Independent Variable • Dependent Variable • Constants

• Hypothesis: Distance Ball on Ramp Lab Time – sketch in graph form – in words “I think when objects fall the distance depends on the time fallen in a ______ relationship”

Ball on Ramp Lab • Roles: – Each group will have a different height • 1 roller • 3 timers

Computer and White Board Roles Distance ball rolled (m) 0. 6 m high ramp Distance = ____ * (time)2 Time ball rolled for (s)
