kdeno Posted February 8, 2008 Share Posted February 8, 2008 I am doing a 45 min program at the lib for grade school children. I found some books but I am drawing a blank on science project ideas. Can anyone help? Thanks, Kari Quote Link to comment Share on other sites More sharing options...
Sebastian (a lady) Posted February 8, 2008 Share Posted February 8, 2008 I was thinking of how ice is used to make roads drivable by lowering the freezing point of water. Maybe you could sprinkle rock salt on a bowl filled with ice and leave another one plain for comparison. If you have a town road salt depot, you might see if the public works folks will give you a little bit of road salt to pass around. I remember thinking that it was really interesting, much larger than I'd expected. Quote Link to comment Share on other sites More sharing options...
Unicorn. Posted February 8, 2008 Share Posted February 8, 2008 I can't think of anything- but I thought I'd bump ya up on the list. Quote Link to comment Share on other sites More sharing options...
Mrs. Readsalot Posted February 8, 2008 Share Posted February 8, 2008 Snowflake Bentley is a beautiful book and I am sure it will inspire some science ideas. The book is a true story of a man who was determined to take pictures of snowflakes. You could hand out sheet for starting rock candy crystals at home. You could cut out snowflakes. Most crystal projects take time and would be difficult to do in an hour library program. You could take inexpensive microscopes and let the kids look at slides through them.

Closeacademy Posted February 8, 2008 Share Posted February 8, 2008 If you have snow you could fill up two cups at the beginning of the program one with water and one with snow. Mark the levels on the cups. At the end of the program check the cups again and find out what the levels the water and snow are at and talk about what has happened. This is from the HOAC lapbook on snow. We wanted to do this one but we really haven't had snow this year. Quote Link to comment Share on other sites More sharing options...
kdeno Posted February 8, 2008 Author Share Posted February 8, 2008 I will post a super mini unit study on snow when I get it together. Feel free to add any other ideas :-) Kari Quote Link to comment Share on other sites More sharing options...
