The BBC's website is full of great educational materials, the Interactive Body is just one example of that. The Interactive Body has students place bones, muscles, and organs in their proper place using a simple drag and drop interface. Along with the "jigsaw" style activity of the Interactive Body the BBC offers fact files about each part of the body.
Applications for Education
The Interactive Body is difficult and challenging making it a good tool for high school students studying anatomy and physiology. It could be used to introduce students to anatomy and physiology as a prior knowledge assessment or be used as study and review guide.
