LAW OF CONSERVATION OF ENERGY
ENERGY CANNOT BE CREATED OR DESTROYED, IT JUST CHANGES FORMSlide2
THERE ARE LAWS AROUND HOW ENERGY MOVES.
The Law of Conservation of Energy states that energy cannot be created or destroyed, it only changes from one form to another.
Example Using the hair dryer showed electrical to mechanical to thermal energy to do its job.

Energy cannot be created or destroyed, but it can be transformed. When we say we are using energy, we are changing one form of energy into another.
Use the marbles and ruler to apply the Law of Conservation.
Applying the Law of Conservation of EnergySlide5
Place your marbles in a row in the ridge of your ruler.
Applying a force on an object can cause motion, a form of energy.
Apply a force by flicking a single marble at one end of the ruler so it hits the other 4 marbles.Write in your chart what happens.
Apply another force by flicking two marbles.
Apply a third force by flicking 3 marbles.Applying a forceSlide6
The law of conservation of energy states that energy can neither be created or destroyed; it just changes form. How does this law apply to your activity?
What did you observe as you flicked one marble?
Two marbles?Did you observe a pattern as you flicked different amounts of marbles?
Write a brief description explaining the connection between the Law of Conservation of Energy and your results.
