If you are teaching human anatomy to primary-age students, you can make the curriculum more interactive by providing the kids with a hands-on model of a human body part, such as an eye. Although you can buy a 3-D eye model from an educational supply company, it can be very costly. One solution is to make your own 3-D eye model out of a few basic craft materials that can be purchased from an art store.
Things you need
- 20-cm (8-inch) foam ball
- White acrylic paint
- Brown modelling clay
- Black modelling clay
- 5-cm (2-inch) round lens from a pair of glasses
- Hot glue gun
- Hot glue stick
Hold the foam ball in one hand. Press an unsharpened end of a pencil into the foam ball to make a 5-cm (2-inch) wide, 5-cm (2-inch) deep hole.
Paint the outside of the foam ball using white acrylic paint. Allow the paint to dry completely.
Press brown modelling clay into the hole. This will be the iris of the eye.
Press a 2.5-cm (1-inch) circle of black modelling clay into the iris. This will be the pupil of the eye.
Insert a hot glue stick into the hot glue gun. Plug the gun into a wall outlet to heat up for a few minutes.
