Guide Questions 1. What happened when the wind came in contact with the pinwheel? What form of energy is shown? 2. What happened to the bits of paper when the plastic comb was placed near them? What form of energy is shown? 3. What did you feel when you placed your finger near the flame of the lighted candle? What form of energy is shown? 4. What was the movement of the ruler when plucked? What form of energy is shown? 5. What were the changes that you have seen inside your bedroom or any part of the house when the light was off? When switched on? What form of energy is shown?

1. Face the front of your pinwheel and blow directly at it. Imagine that the pinwheel is a wind turbine, and when it spins in this direction it is turning the energy of the wind into electrical energy.

2. You can observe static electricity if you run a plastic comb through your hair, then place the comb near small pieces of paper. The paper is attracted to the comb. This happens because the charged comb induces an opposite charge in the paper and as opposite charges attract, the paper sticks to the comb.

3. You will see the tall candle goes out first. the flames are consuming oxygen and produce carbon dioxide. the product is hot so it is less dense than the cold air. hence the carbon dioxide rises to the top and suffocate the fall candle.

4. ping a ruler on the edge of a desk while changing the length that can vibrate. hear how the pitch changes, and notice how the vibration frequency changes the form of energy shown is sound

5. When light hits an object, part of the light gets absorbed, part of it is transmitted trough the object, and part of it is reflected/scattered. Exactly how much gets absorbed, transmitted, or reflected depends on the material, shape, and thickness of the object.
