Sound and Light I
One important difference between sound and light is that sound can only travel through a solid, liquid or gas. Sound can not travel through a vacuum. For example, sound can not travel through outer space. Light on the other hand, can travel through a vacuum. This topic explores the electromagnetic spectrum.

Compare Contrast and Debate
Background: Visible light is only a very small portion of the electromagnetic spectrum. For example, x-rays and radio waves are also on the spectrum. Some teachers introduce the entire electromagnetic spectrum all at once. Other teachers introduce concepts of visible light first – then the other parts of the spectrum.
- Position A: The best way to learn about the electromagnetic spectrum is to introduce the entire spectrum first – then show how visible light is part of the spectrum.
- Position B: The best way to learn about the electromagnetic spectrum is through visible light (such as a rainbow) – then introduce the other parts of the spectrum.
