TEKS & Objectives
7.7. Force, motion, and energy. The student knows that there is a relationship among force, motion, and energy.
8.8.C identify how different wavelengths of the electromagnetic spectrum such as visible light and radio waves are used to gain information about components in the universe
7.2.B design and implement experimental investigations by making observations, asking well defined questions, formulating testable hypotheses, and using appropriate equipment and technology
We will explore the relationship among force, motion, and energy.
I will investigate the practical effects of energy transfer.
1. Watch video about refracting light.
2. Watch video about absorbing light.
- This paint is so dark, that it absorbs almost ALL of the light that falls on it!
- It’s so dark that you can’t see the object’s texture.
3. Review vocabulary and complete flip book.
Light refraction Light BENDS as it passes from one surface to another.
Light reflection Light BOUNCES off the surface of an object.
Shadows These dark shapes are made from BLOCKING light.
Absorbed Light is not reflected, but converted into HEAT energy.
4. Try the light refracting demonstration from the first video.
5. Try a second light refracting demonstration below:
Speaking of light…
How many musicians does it take to screw in a lightbulb?
A-one, a-two, a one-two-three-four!
6. “Review of Light”
