I just discovered an excellent model of an eyeball that was sent to me by Aurora Lipper. She demonstrates how to create an actual eyeball model. Aurora has produced a "must see" video on exactly how to make the eyeball using a balloon and an inexpensive lens.
Click Here for Eyeball Science to visit her link. This video is set up so you can show it to your class and then have them make it the second time. She also includes a student worksheet.
If you like this video, Aurora also have a complete mini-video series that she will send you for free by clicking HERE for the Mini-video series.
This mini lesson will create excitement among my students while giving them a chance to learn about how the eye works.
