2. What cards, in general, show an energy dump?
3. What color card is used for a transducer?
4. What color cards are the input and output to a transducer?
5. Show the input and output cards for a generator.
6. Show the input and output cards for a lamp.
7. Show the input and output cards for a electric heater.
8. Show the input and output cards for a motor.
9. Show the input and output cards for a engine.
10. Show the input and output cards for a microphone.

Gave students a choice. They could have their quiz graded or they could take notes.

Quickly reviewed the basic cards.
Reviewed all the transducers.
Reviewed the energy dumps.

New material, more complicated systems. Finished presentation 1.
Went on to Power Stations. Handed out green sheet with summary of power stations.
Many of the them are the same. KE --> turbine--> KE --> generator --> electricity
Mentioned acid rain and the greenhouse effect. Bad effects of leaving dogs or children in closed up cars on hot days. The light energy can get in but can't get out so the inside gets very hot.
Basically finished power plants.

Quiz next time.

Last day to make up any missing tests is this Friday.

Go to quia website for practice on energy cards.
