Energy:�
Ability to do work
There are many different forms of Energy
Light
Nuclear
Chemical
Motion
Electrical
Sound
Heat/Thermal
Elastic
Partner Up�Discuss the following question with your elbow partner. . .
Question:��“What forms of energy are shown on each of the following slides?”��(Record your answers on Student Sheet Part 2)
Electrical
Heat and Light
Motion
Sound
Elastic
Chemical
Gravitational
Nuclear
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 many fairy tale transformations can you name?�
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!

“Stored Energy”
Energy that has not been used. . .YET
Kinetic
“Active Energy”
Energy where something IS happening. . .NOW
All energy can be divided into TWO types. . .
ENERGY
Potential

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. . .
Potential Chemical Energy which will now be stored (waiting to be used) in the plant as sugar. . .
Kinetic Light Energy
Which is traveling (active) from the Sun to the plant can be converted into. . .
