Safety Note: Laser Pointers Although the laser pointers in the kit are fairly low energy, they should not be shined into eyes.

Claim 1: Can light travel in a curved line? What evidence do you have?
CFS:
Accurately identifies the type of light reactions that cause changes in objects
Accurately describes the relationship between light interaction and outcomes
Claim 2: Can light travel through (be transmitted through) some objects?
Claim 3: Can light travel bounce off/reflect off some objects?

Lesson 3.1: Following the Path of Light
With a partner, discuss which types of light you think will pass through glass and which will pass through aluminum foil. Note your predictions below.
I predict that __________________________ will pass through glass.
Instructions:
Investigate what happens when light hits glass and when light hits aluminum foil. Remember:
If the light is taken in by the material, it is absorbed.
If the light passes through the material, it is transmitted.
If the light bounces off the material, it is reflected.
1. Open the Light Waves Simulation
2. Choose Custom and turn the light source on.
3. Drag GLASS to a platform in the testing area.
4. Move the slider to select different wavelength/types of light and test how they interact with glass.
5. Record the results below.
6. Repeat steps 3 and 4 with ALUMINUM FOIL.
Did the same outcome happen to every type of light when it hit glass?
I predict that __________________________ will pass through aluminum foil.
What evidence do you have to support why different materials have different outcomes when they interact with UV light?

Accurately identifies the type of light reactions that cause changes in objects
Accurately describes the relationship between light interaction and outcomes
In glass and aluminum, explain why different types of light react differently to the two types of material? (think: why does visible light react differently to aluminum than glass?)
