Task guiding students through describing energy transfers.
Can be done in groups or individually.
Mathc the energy stores with the description
| Stavka koja se može prevući | arrow_right_alt | Odgovarajuća stavka |
|---|---|---|
Energy stored in a stretched rubber band | arrow_right_alt | Kinetic |
Energy that is emitted from a glowing object | arrow_right_alt | Chemical |
Energy stored in an object above the ground | arrow_right_alt | Heat or thermal |
Energy stored in a hot object | arrow_right_alt | Light |
Energy stored in food and fuel | arrow_right_alt | Elastic potential energy |
Energy transferred along wires in devices | arrow_right_alt | Gravitational potential energy |
Energy associated with movement | arrow_right_alt | Electrical |
Decribing energy transfers
For each example you need to:
1) List the types of energy stores at the start
2) Describe what is happening
3) List the energy stores at the end
We will do two examples together
Example 1 a) DDescribe the set up of the example and what is happening / will happen.
Example 1 b) List the original energy stores (in this case the energy stored in the candle).
Example 1 c) List the stores of energy at the end.
Example 2
Example 2 a) Describe the set up of the example and what is happening / will happen.
Example 2b) List the original energy stores (in this case the energy stored by the ball before being dropped).
Example 2c) List the original energy stores at the end (in this case the energy stored by the ball just before hitting the floor).
Now you need to work in your groups doing your own examples.
So have a look around and find some examples of simple energy transfers. Some examples are toys, small electrical devices, yourself/pets, any moving objects.
For each one you need to:
a) describe the example and describe what is happening
b) list the energy stores at the start
c) list the energy stores at the end
Energy transfer 1
a) Description
b) Energy at the start
c) Energy at the end
Energy transfer 2
a) Description
b) Energy at the start
c) Energy at the end
Energy transfer 3
a) Description
b) Energy at the start
c) Energy at the end
Energy transfer 4
a) Description
b) Energy at the start
c) Energy at the end
Energy transfer 5
a) Description
