Frogs are often considered to be the best jumper out of all the vertebrates in the world today. Their bone structure has developed over time to allow for them to push against the ground for a longer period of time, which helps them to jump higher and longer. The Australian rocket frog is a great example of a frog that has an excellent jump--it can leap over 50 times its body length! Learn more about the wonders of frogs through this great slide set. This set of slides features five different parts of a frog (frog lung, frog skin, frog liver, frog kidney, and frog intestine). It also comes with a guide of interesting facts about the specimens. This is a great science resource for any classroom, and is a great alternative to show students if they (or the teacher!) get squeamish about dissecting a frog. An awesome home-schooling resource, this set can be used with any compound microscope you have at home or at school. A great scientific educational gift for the aspiring young scientist in your family!

With this kit, you can conduct 25 experiments to learn how an electric motor converts electricity into motion, and how an electric generator does just the opposite, converting motion into electricity.
