Why did the experiment have metal clips to attach to the batteries and the light bulb?
Metal is a good conductor of heat. Electrical energy was transformed into heat energy which caused the bulb to light up.

Why did the pencil look broken when placed in the cup of water?
The light passed through the pencil at different speed. Therefore, the bending of the light occurred at different times which caused the pencil to look broken.

What provided the light energy from the experiment?
The light bulb provided the light energy. The more heat energy is resisted; the more light the bulb will provided.

What is the difference between pitch and volume?
Pitch is how high or low a sound is and volume is a measure of how strong a soun seems to be.

Why do you see different colors when you shine white light into water and a mirror?
The mirror separates the white light into different colors or wavelengths.

How were the different types of energy transformed into other types of energy?
The batteries provided electricial energy which transformed into heat energy where the metal clips worked to transport heat energy. The heat energy transformed into light energy.
