Challenge: Have a light source touch all three objects below in the same trial!

Materials:
Light Sources
1. Sun
2. Light bulb
3. Laser

· Aluminum foil
· Sunscreen

The Effects of Different Light Sources
Emit the light source on each material to help you answer the Investigation Question: Is all light the same?
Record your observations in the table below. Describe the effects of the light emitted from each flashlight, and note whether they are different from one another.

Reflection: Based on your observations, is the light emitted from the Sun the same as the light emitted from the Light bulb? How can you tell?
CFS:
  • Accurately identifies the differences light sources
  • Accurately describes the relationship light and its effect on another object
  • Explanation includes 1-2 pieces of supporting evidence/reasoning.
"Based on my findings I think that the light from the Sun is different than the light bulb.
This is because ....
There were changes because ... "

Jonathan claims that light is always the same, even when it is emitted by different light sources (like the sun and a light bulb). Do you agree, disagree, or neither?
CFS:
  • Accurately identifies the differences light sources
  • Accurately describes the relationship light and its effect on another object
  • Explanation includes 1-2 pieces of supporting evidence/reasoning.
"I think all light is the (same/different). I think this because some light sources can cause changes by ... . Others do not cause changes because ... "
