Back awhile ago, I created a list of my favorite science web sites for kids and sent the list to a couple of friends. My kids come home with plenty of math web sites (CoolMath.com is a definintely a popular one), but not as much sites specifically relating to science. So I made the following list.
Awesome Science Sites for Kids (and their Parents!)
Mythbusters on YouTube - One of the best shows on TV is also on YouTube!
How Stuff Works on YouTube
Brain Pop - This site has everything!
Zoom Kitchen Chemistry - PBS Kids. I remember watching this show when I was young.
Virtual Knee Surgery - This is cool! (Ouch!)
Steve Spangler Science on YouTube
Discovery Channel - the Human Body - a great visual, interactive site
National Geographic Kids Beautiful site of videos, games, and activities. Honestly, I like this better than the adult site.
Funology - the Science of Having Fun
Mystery at Ghost Mine - Solve a Mystery
Your Weight in Other Worlds - Okay, I don't want to know my weight in my own world. Why would I want to know my weight in other worlds? My kids think this site is fun though.
