CIA 2-1 Review
We are learning to: identify different forms of energy We are looking for: identification of the following: Chemical – energy stored in the bonds of atoms Electrical – energy in moving electrons Mechanical – energy in motion Thermal – heat energy Acoustic – sound energy Nuclear – energy stored in the nucleus of an atom Electromagnetic – visible(radiant), UV rays, microwaves, etc.

We are learning to: explain the law of conservation of energy. We are looking for: how energy can change from one form to another without the loss of overall energy We are learning to: trace energy transformations in a closed system (i.e., flashlight) We are looking for: the ordering of how one form of energy changes (transforms) to another. (See aforementioned types of energy)
