hmschooln Posted April 26, 2011 Share Posted April 26, 2011 Okay I need some suggestions of science experiments/demonstrations to wow some dc. I'm not really worried about going in depth to explain the concepts just need the ohh and ahh factor. Any ideas? Thanks:001_smile: Quote Link to comment Share on other sites More sharing options...
Jean in Newcastle Posted April 26, 2011 Share Posted April 26, 2011 It's hard to give you ideas without know the ages of the children. What will wow but still be safe around a younger child is quite different than what will wow a teen. Quote Link to comment Share on other sites More sharing options...

peacefully Posted April 26, 2011 Share Posted April 26, 2011 Well, my ds is only 6, but these air pressure demonstrations also had my 8-12 yo nephews really excited. The first is keeping an upside-down full glass of water from pouring out, using just an index card. It takes a while for the kids to figure out what the heck is going on. I ask them to try to do it and explain what is going on. The second is crushing an empty soda can, simply by creating a vacuum inside the can. You heat a small amount of water in the can on your stove until the water is vigorously boiling (thus steaming). Then you quickly turn the can over into a shallow pan of water, creating a seal. Wham! The can collapses with a loud POP! Quote Link to comment Share on other sites More sharing options...
