DIY model of human eye?
I'm posting this question under homeschooling because this is the kind of weird thing that another HSer is sure to have done :-)
Granddad is having cataract surgery so naturally dd (age 4) wants to know all about it. I've shown her a diagram and explained the procedure but it would be nice to make a model too. Something using common household and arts & crafts materials if possible, or a paper craft thing that I could print out and make. Any suggestions?
