momsuz123 Posted February 12, 2012 Share Posted February 12, 2012 and a bag and oil. We just taught our kids about polar bears, and I had a science experiment flagged, but can't find it. It was where you fill up a pot or bucket with ice, and then have a bag of oil, and the kid put there hand in the bag vs the ice water to see how polar animals can withstand the water. Thanks.

Dana Posted February 12, 2012 Share Posted February 12, 2012 I don't have it... but I thought it was a bag of something like Crisco and they could put their hand in a bag inside the bag of Crisco (so you don't get gloopy hands) and the fat is to show the insulation the polar animals have. Contrast with hand just in bag in water. Quote Link to comment Share on other sites More sharing options...
daybreaking Posted February 12, 2012 Share Posted February 12, 2012 We did a similar one with HOD, where my ds smeared shortening all over one hand and then put both hands in ice cold water. It's messy, but it works really well to demonstrate the impact of blubber. Quote Link to comment Share on other sites More sharing options...
momsuz123 Posted February 12, 2012 Author Share Posted February 12, 2012 Thanks both of you! I thought I had it saved, but I couldn't find it. We are just starting our new science unit. DH started with a great book on polar bears, now they are watching a NG video, then we do some experiments. Thanks. I am excited to start this new unit, that we are making up as we go.:001_smile: Quote Link to comment Share on other sites More sharing options...
