What's a better way to start the new school year than with some new experiments? Learn how to use a variety of color changing experiments to teach students about the Diet Coke and Mentos experiment, acids, bases, chemical and physical changes, and climate change.
You can figure out how this Valentine's Day experiment was done...if you know your chemistry, that is!
I have tried many different methods to demonstrate or perform displacement reactions over the years with mixed results regarding one particular metal, aluminium. Based upon my experience, the behavior of aluminium in displacement reactions often confuses students.
A description of a quick and easy lesson that is sure to add some spark into your next lesson on stoichiometry.
I have a first day routine that I am very proud of. I have used it for 25 years and I think I finally have it down pat. I have spoken to students from 20 years ago at reunions and they tell me that they still remember the first day of chemistry so I think it is pretty good.
I have been involved in several types of community outreach projects to promote science education and chemistry. One of the best was a biannual event I worked on with teachers from each elementary school in our district and from our middle school. It was a Science Extravaganza.
The “Elephant Toothpaste” experiment is a very popular, albeit messy chemistry demonstration. To carry out this experiment, place a 250 mL graduated cylinder on something that you wouldn’t mind getting messy.
