Energy: Ability to do work
There are many different forms of Energy Elastic Nuclear Light Sound Chemical Motion Electrical Heat/Thermal
Partner Up Discuss the following question with your elbow partner. . .

All forms of energy can be transformed. This means energy can change from one kind to another. . .
Energy is similar to a fairy tale in which there is a transformation. . .
Here’s one example. . . In the Princess and the frog, the princess kisses the frog. . . And then she becomes a frog too!
How m any fa i r y tale trans forma tions can y ou na me?
Discuss the following situations with your elbow partner. . .
Question: Can you identify the energy BEFORE and AFTER the transformation?
Electrical Light + Heat
Chemical Motion + Heat
Energy Transformation Cards With your partner. . . match the energy pictures with the energy transformations
Let’s See How You Did!
Electrical Heat + Light
Chemical Motion

All energy can be divided into TWO types. . . Potential Kinetic “Stored Energy” “Active Energy” Energy that has not been used. . . YET Energy where something IS happening. . . NOW
ENERGY Potential Elastic Chemical Nuclear Gravitational Kinetic Sound Heat Electrical Motion Light
How about in this example? Potential Chemical Energy which has been stored in the battery is now being converted into. . Kinetic Light Energy Which is now traveling from the flashlight (it is DOING something!)
The opposite can also happen. . . Kinetic Light Energy Which is traveling (active) from the Sun to the plant can be converted into. . . Potential Chemical Energy which will now be stored (waiting to be used) in the plant as sugar. . .
