Review how a mechanical energy transfer is diagrammed by clicking here.

1. Remember how you diagrammed an electrical energy transfer in 6th grade? Of course you do. Now draw the energy transfer diagram to show how a battery is charged.
2. Now show how the energy transfers when a battery lights a bulb.
3. Let's try Life Science. Remember carbon stores? Of course you do. Show how energy transfers from the sun to a plant.
4. Next show how energy transfers when a rabbit eats the plant.
5. And now show how energy transfers when a wolf eats the rabbit.
6. Even in Earth Science we can diagram energy transfers. Remember how heat energy moves in conduction, convection and radiation? Of course you do. Try diagramming how heat transfers from a pan to an egg when you fry an egg.
7. Now diagram how the heat from a light bulb warms your hand.
8. And finally, diagram how a heat energy transfers from a bulb in a lava lamp to make a lump of wax expand, become less dense, and float to the top of the lamp. Use warmer wax and cooler wax as the source and receiver for this one. Hmm, that's what happens in our planet's mantle and that's what causes continental drift. Imagine if Alfred Wegener had known that!
