Marshmallow Masher | Science Experiments | Steve Spangler Science
Marshmallows are a tasty, fluffy staple of summertime s’mores, campouts, and backyard barbecues. There really isn’t very much to them, either. The scientific way to see what really fills a marshmallow is to put it to the Marshmallow Masher test. You use a property of air to demonstrate what’s really on the inside of those roasted ‘mallows you make around a campfire. It’s not all sugar.

control a spill, and understand how to use the safety equipment. Continue reading
Playing with Fire: Chemical Safety Expertise Required – submitted by Milan Sanader
This recent article from the Journal of Chemical Education is an excellent overview of accidents that have happened involving flammable liquids. The authors report 164 children and educators have been injured over a 20 year period. The article also provides useful insights into why these accidents occur and measures necessary to prevent them.
In my opinion, this article is a “must read” for any science teacher considering bringing a sample of a flammable liquid into their classroom.
Thanks for sharing this idea Milan !
