I ran into this fabulous free resource by accident. It is developed by the Dairy Industry of Australia and has 3 modules - all with free video, graphic and printable resources. Even a free dairy DVD for teachers. Cool!
The first topic, 'Unbeatable Bones', covers the importance of building and maintaining strong, healthy bones throughout life. You can discover bone basics and the skeleton, nutrition for bone health, osteoporosis, how to build unbeatable bones with dairy foods, and lots more.
