I am teaching this summer and it is especially exciting as I am piloting the labs I wrote this spring. We are using these labs exclusively and I am collecting student feedback for each lab to help in the editing, refining, and revision process.
In a previous blog post, I shared my thoughts about the importance of science teachers (and all teachers, really) supporting their claims about lesson efficacy with evidence. While this doesn’t always need to be a formal research study, it can often be valuable to publish findings that will be helpful to other science teachers.
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.
Some orange peels can cause balloons to pop. The compound in orange peels called limonene is responsible for this effect. Limonene is responsible for the wonderful smell of oranges, and it is a liquid at room temperature.
A fun experiment to conduct when discussing phase diagrams is the melting of solid carbon dioxide (dry ice).
Last year I came across a link on Twitter regarding an art installation by Roger Hiorns in England titled “Seizure.” Some of you may have seen it too – a condemned flat in London was essentially sealed off and filled with more than 75,000 L of supersaturated copper sulfate solution.

Conducting experiments with liquid nitrogen experiments is a sure-fire way to energize many chemistry lessons. Check out the Misbehaving Balloon demo!
At my school in Michigan, the second semester just started this week. And, since all chemistry classes (except for IB Chemistry) are semester courses, I have new students and different preps.
Happy New Year! For many, the beginning of a new year involves creating resolutions. And, hopefully not quitting them! Something I have resolved to do is modify the presentation and submission of lab reports.
