Energy Conversion Stations
Name: ________________________________________ Class: ____________
Station #1
Directions: Fill the beaker approximately 50 mL with vinegar. Place about 1 tablespoon of baking soda into the beaker with the vinegar.
1. What type of energy occurs before the reaction takes place?

2. What types of energy is produced as the reaction is occurring?


Station #2
Directions: Blow up some of the balloons; let them go and see what happens.
1. What type of energy is needed to stretch a balloon? Think about what you have to physically do in order to stretch a balloon.

2. Blow up one of the balloons. What kind of energy does the inflated balloon have?

3. When you release the filled balloon, what types of energy are produced from the stored energy in the balloon?

Station #3
Directions: Rub your hands together, gradually picking up the speed for 30 seconds.
1. What type of energy did you use to rub your hands together?

2. What type of energy was given off when you rubbed your hands?


3. If you rub your hands together faster, how does the amount of energy change?
Station #4
Directions: Hold the meter stick vertically with the zero end on the counter. Drop (do not throw) a ball from the 50 centimeter mark and record the height to which the ball bounces back.
1. The ball bounced back to the _______ cm mark. Why can’t the ball rise back to the 50 cm mark?

2. This is because some of the ________________ energy converts to _____________ & ______________ energy.

Station #5
Directions: Look at the picture below of a roller coaster. List which position represents the greatest amount of potential energy and which represents the greatest amount of kinetic energy. Explain your answers.

Point ____ has the greatest amount of potential energy because ________________________. Point ____has the greatest amount of kinetic energy because __________________________.
