GOALSMake goals for this energy unit. What did you do well to be successful in the Matter unit? What could you improve on for the energy unit?

Explain the transformations:

October 13th 2015 page 69DO: I will be able to breakdown the

relationships as well as unique characteristics the forms and types of energy as well as heat transfer in everyday instances. EQ: 1.Describe how all energy comes from the SUN; give examples to clarify your explanation.2. Explain the relationship between the Law of Conservation of Matter and the Law of Conservation of Energy.

Warm UP

Transformations• The purpose of a nuclear power plant is to transform nuclear energy into

electricity. This is done is steps starting with a nuclear reaction which generates heat to produce steam. The steam in turn is used to turn a generator which finally produces electricity. If you were to create an energy transformation which type of energy would come first? Second? Third? Fourth?
