Directions:

Part I – Power point presentation and notes You are working with your shoulder partner to strengthen your

understanding on energy. Specifically kinetic and potential energy.

Outcomes

I can explain and identify examples of kinetic and potential energy I can explain and apply the relationship between kinetic and

potential energy. I can apply the law of conservation of energy to energy simple

energy transformations.

2.____________________________________________________________________________________________________________________________________

2. Go to http://www.science-animations.com/support-files/energy.swf

Watch each of the animations – pay close attention to the amount of PE (potential energy) and the amount KE (kinetic energy)

Choose one of the animations to explain. I am explaining the ________________________________ animation.

Explain the relationship between PE and KE in your animation.
