Science Website: 3D Toad

 A great website called 3D Toad has a free gallery of 3D objects from skeletons to dissections to molecule structures. Use your mouse to zoom in and out or rotate the objects. If you have access to 3D glasses, you can use them to view some of the images even more clearly. Just look for the red and blue glasses icon. The clip below shows a teacher using the dental hygiene section of the website.
