Use the worksheet provided to collect and record data from the following experiments:
Use your pushpin to poke a single hole anywhere in the foil on your viewer. Turn on one light (of any color). Hold the viewer up to the light, with the foil side oriented towards the light, and look at the image on the wax paper. Record your data. Turn on a second light, and then the third light. How many images do you see?
Poke a second hole in your foil and hold it up to the light, again starting with only one light on, then two lights on, then all three lights on. Record this data.
Continue poking additional holes in the foil. For each new hole, test the viewer against different numbers of lights, and record your observations as you go.
Do you see a pattern in the data? What is the relationship between holes, bulbs, and images? Based on that relationship, make a prediction: if you know the number of holes poked and the number of bulbs, how many images will appear? Can you represent this as a mathematical formula?
