3D Toad is a nice site that hosts images that viewers can zoom-in on and rotate 360 degrees. The site is designed to provide educators and students with images that are useful for instruction. In the galleries of images include history, geology, chemistry, skeletons, fossils, and more. Click and hold on any image to rotate it. Double click to zoom-in on it. Each image is accompanied by a short caption. The video below offers a short introduction to 3D Toad.
Applications for Education
3D Toad offers a couple of video examples of how teachers might use the images. I've embedded one of those videos below.
