This site has several templates and lesson plans elementary teachers can use to have students make books. Books are made using programs such as PowerPoint, Word, and Publisher. A good way to integrate technology into whatever you are teaching.
This site has flash teaching-aids that were created to be used on a SmartBoard. All of this site is science related- you'll find things for physics, chemistry, biology, scientific literacy, and more. There are also teacher templates so you can create your own activities as well as directions for downloading these to your computer so you don't have to be connected to the internet to use.
