Chapter 1: Changes Caused by Light
Lesson 1.3: Exploring Change from Light
Part 1: Sunlight
Open the Light Waves Simulation in Simple mode and follow the steps below.
1. Choose a material and drag it to platform 1 in the testing area.
2. Keep SUN as the light source and turn it ON.
3. Press INSPECT to see the effect of the light on the material.
4. Observe whether light from the sun causes the material to change.
a. Change has occurred if the material is different after the light is turned on.
5. Place different materials in the testing area until you find at least one material that is changed by light from the sun and one that is not.

Predict and explain which type of light interaction do you expect to cause a change on the object?
CFS:
Accurately identifies the type of light interactions that change objects
Accurately describes the relationship between light interactions and changes in objects
