LAB: That's The Way The Ball Bounces - conversion of energy
Mini-Lab #1
Stack 3 to 4 books. Place a piece of waxed paper between the top book to hold it to form a ramp. Using a dropper, place a drop of water at the top of the ramp. Observe its motion. Repeat several times, each time altering the shape of the ramp. Before releasing the drop, predict its motion. Record on a drawing where you released it, and what you think will happen. (from Bankston)

TURN IN:
1. Full Heading
2. Drawing with each trial labeled (Trail #1, Trial #2...) and predictions for each trial.
3. Explain the reasons for your predictions (complete sentences)
Mini-Lab #2
Using two thumbtacks, attach opposite ends of a stretched rubber band to a board to form a slingshot. Carefully use the slingshot to propel a ball along the board. Relate the kinetic energy of the car to the elastic potential energy of the rubber band by measuring the stretch of the rubber band and comparing it to the distance that the car travels.
What factors determine elastic potential energy? (from Bankston)

TURN IN:
Full Heading
1. Turn in data table with information that supports your findings (distances, stretch...)
2. Relation of kinetic energy to elastic potential energy (complete sentences) use data to explain or support your findings.
