Veritasium in the Modeling Classroom

Modeling InstructionTM is specifically designed so students construct meaning without being told what to think and I needed videos that aligned with this philosophy.  That’s when I ran across this TedEd talk with Dr. Derek Muller.

The Gas Laws Are Out of This World!

A few years ago, we launched a weather balloon during our summer science camp. The balloon reached an altitude of 30 km (100,000 ft)! Among other things, this project ended up being a great way to teach campers about the gas laws and how atmospheric pressure decreases with altitude. 

Melting Pennies

I am fascinated by the chemistry of pennies. I have tried several experiments found in the Journal of Chemical Education.

Using Twitter for a Backchannel Chat During a Fish Bowl Discussion

In a previous post, I discussed the work of my grade 10 class as we read the non-fiction story, The Case of the Frozen Addicts. We've continued working our way through the book, taking one class every two weeks to delve into the issues presented. Just this week, we engaged in a fish-bowl discussion. To help steer the discussion, I started the class with a quick warm-up activity asking students to suggest topics or questions that they would want to talk through in the fish bowl.

Hunting for Chemicals in Consumer Products

In this Activity, students use written clues to determine the identities of 12 chemical compounds. They write the name and chemical formula for each compound, and find a consumer product in which each compound is present. This Activity increases student awareness of the presence of a variety of chemical compounds in a range of common consumer products.
