Eyeballs

In the first of a series of classes exploring our senses, the electrons did a few experiments to find out how our eyes work. We built a model eye using a magnifying glass and a goldfish bowl. We used a cut out of a person and vellum paper taped to the fishbowl to act as a retina in the back of the eye. Then the electrons shined a flashlight on the figure to show how the eye forms an image of a human figure using it’s lens (magnifying glass), eyeball (round fishbowl), and retina (vellum paper). Our next experiment showed how our two eyes work together and how we can see moving pictures on tv and in the movies. We used a circle of cardstock, punched holes in sides for string, and drew a picture on each side. Then the electrons twirled the card to show the two images melding together into one.
