I think this is a great web site because it offers everything that you need. This site allows you to choose from sounds, movies, animation and movies. It has everything from animal movie clips to NASA movies. It is a great website and it would be a great tool.

I found this great website that has everything you would need to do a project. It has sound, pictures, video and music. It even has a link to microsoft office and their clipart and media. The music they have is from classical to kids music. This website also has animated clip art and images. This was a fun website to visit.
