1. Instructions
- Collect 5 squares of paper, label one side of each square with your number and paint the opposite side of each with each diluted paint. Let dry for 10 minutes.
- Set up your light box and put the light sensor under it. Make sure it is centered under the shaded-in area and tape it down.
- Connect a light sensor to analog plug 0. Connect a aligator clip sensor to analog plug 2.

4. Conclusion Questions
Goals Answer all questions
Submit your answers
| What does the analog sensor tell you specifically? Hint:
What type of sensor is this?
How can you tell?
While running the experiment on the computer,
what differences did you notice with each square?
Note the position of the center alligator clip
and the knob values for all dilutions.
What does the change in light values actually mean? Explain.
What are some real-life examples in which this type of sensor is used? Explain.
