I have had a difficult time finding age appropriate and engaging research material for primary and intermediate students at my elementary schools. I have recently found one useful website that helps engage students in possible research topics. It includes easy to follow tabs that include sound and audio, maps, easy printing features, photos, and facts.

Here is the website and I am focussing the study on animals:

Hope this helps! Please let me know of any other kid friendly research websites!
