Reflections on a (Virtual) Guest Speaker Visit to my Chemistry Class
I've mentioned previously that my current grade 10 class is reading "The Case of the Frozen Addicts" together. As my students starting writing their blogs to respond to the reading, I saw quite a few questions that I couldn't answer. But I didn't want to leave the questions there with no response, so I went to Twitter to find scientists to join my class as a guest speaker.

A Modeling Approach to Energy Storage and Transfer
From the misconceptions fostered by the biology textbooks using the phrase “high-energy phosphate bond” to idea that energy comes in different forms, the Modeling community recognizes the challenges of teaching the energy concept and has developed a way of talking about energy designed to help students construct a consistent and cohesive model.
Chemical Riddle #2
A student of mine, Anthony Shepherd, and I worked together to develop a new chemical riddle. Check out the video and see if you can come up with an answer.
Solution to Chemical Riddle #1
In the video below, you can find the solution to the chemical riddle involving the food dye and bleach experiment. You can also find a description of how to set up and carry out the experiment. Finally, an extension to the activity is presented. Thanks to Erica Jacobsen, James Hanson, and Alfredo Ti

Pyrex by any other name...
Did you know that Pyrex glassware used in chemistry labs is different than Pyrex glassware used in kitchens? Pyrex glass used in chemistry experiments is made of borosilicate glass, whereas the Pyrex used when baking is made of soda lime glass. What’s the difference?
