From Hydroelectric Power to Electricity

Content:
Here you will learn how water power can be used to generate electricity...
Safety:
-

Teaching Tips
- in summer, outside, have fun getting wet...
- 1. extended observational experiment which can accompany work over a long period of time. One device to every two pupils. Optimal position is on a windowsill to allow observation.
- 2. Outside, we are going to get sprayed - it's fun and makes sense
. One device for two children (logo)
- 3.Resulting measuring device is needed for 4. The measuring device can only be assembled when 1 is dissembled.
- 4. If it doesn't work unscrew the attachment and if necessary unstop the warm water. A LED can also be attached as a consumer load.
