We often hear people talk about needing energy. A lamp needs energy to light up, a toaster needs energy to work, your hair dryer needs energy to run. But what is energy? |
|
Think for a minute about what energy actually is. |
|
|
Now discuss your ideas with your group. Come up with a group definition. |
|
|
What do you think now? Has your model of energy needs changed? |
|
Look back at your previous answers and drawings. Compare your current ideas with previous models. |
