The Importance of Handwashing

At my middle school there are a few lab activities where hand washing is essential (those with strong acids, toxic chemicals or salmonella with the chicken wing dissection). Getting middle schoolers to wash their hands is not the easiest thing to do. That is why I like to do a demo that clearly illustrates the need.  All that is needed is Glo Germ, a blacklight, and some sort of stuffed object. 

The Importance of Safety Goggles

It's that time of year where school is starting and that means teachers have to go over the safety rules in the science classroom. Teachers who teach chemistry must have all of their students wear safety goggles during lab activities. Being a teacher, whose middle school students don't really want to wear them, I have a simple demo for students to understand the need to wear them.
