A Thing for Chairs!
Julia Winter | Thu, 07/09/2015 - 22:47
Over the past two years, I have immersed myself in designing mobile games for organic chemistry: founding a company called Alchemie and building a team to develop these games. The first of our games is called Chairs! (The exclamation point comes from the fact that an app called Chairs already existed in the AppStore.) The game Chairs! is what we call our proof-of-concept. Folks were a bit incredulous when we told them we design games that make learning organic chemistry intuitive and fun.

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.
ELLs and Science Practices
Shelly Belleau | Fri, 06/05/2015 - 11:38
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.
How Does an Orange Peel Pop a Balloon? Chemistry, of Course!
Tom Kuntzleman | Tue, 03/24/2015 - 15:15
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.
