Feb. 25-Mar. 1 1.What happens when you rub your hands together? 2. When you are cold, what are some other ways you can get warm?

2. Energy can be transferred:  Electricity in a wire transfers the electrical energy.  A light beam can transfer the energy from one place to another. 3. Energy can be transformed (change or converted):  Someone striking a match.  Baking cake in the oven 1.Energy cannot be created or destroyed.  No matter how it changes or moves, it will still be the same amount of energy (conservation of energy).

Explain each of the energy transformations.

ObservationsEnergy Transformation Single or Multiple 1. Lighting a candle 2. Talking on a cell phone 3. Eating food 4. Playing basketball 5. Dish washer

1. A major problem with using electrical energy is that: A) it cannot be converted to other forms of energy. B) it is not easy to store. 2. When you recharge your cell phone you plug it into an electrical outlet for some time. The electrical energy is stored in the phone's battery as ______ energy until you are ready to use the phone. A) nuclear B) Chemical 3. Fossil fuels like coal, oil, and natural gas, are what kind of stored energy? A) chemical B) mechanical
