Dependence of Light Intensity on Distance

Hopefully you have a sensor interface for your physics class to use with graphing calculators when collecting data with a light sensor. If so, read on. Use this resource for learners to predict and then test whether or not the intensity of light is directly related to the distance from the point light source. After the investigation, they associate findings to the forces of gravity and electricity. This is an outstanding activity for introducing the inverse square law.

Lesson Planet has helped me a lot with my previous grade levels from K-6. Now I am reinstating my membership because I know it can help me more with my middle school special education classes.
