Light

When teaching about light, it is a great idea to begin with the structure of the eye and how it allows us to see light. Discuss specifically how the lens bends light. This is called "refracting" light. Other vocabulary to use when teaching about light should include: reflection, refraction, transparent, translucent, opaque, polarization, speed of light, and primary colors.

Primary colors are red, blue, and green. White is a collection of all three colors. Meaning that if you were to shine all three colors in the same spot you would see white, not the individual colors.

Concave lens cause light beams to spread. Convex causes light to concerge or to narrow.

*Fun Fact: If the sun exploded, it would take 8 minutes and 20 seconds for the light to reach us on Earth.
