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.

By the Numbers

How many likes does your page have? How many followers do you have? How many reads for that particular blog post? Page views? Downloads? Number of times cited? Impact factor? In the online world, much of life is lived by the numbers.

Compound Interest

Have you ever been curious about the chemistry of a lemon? What about the chemical structures of adrenaline, dopamine, or serotonin? Would you like to share with your students the elements that make up their smartphone? Or what how about a beautiful “infographic” representing each of the families of the periodic table? Then Compound Interest at has you covered and then some.


It's interesting to me how a word can define a class. The longer I teach, the more excited and quickly I can cover a concept. However, this pace does not necessarily fit well with my students, so we have a code word:  Traxoline (thanks to Judy Lanier).

Painting a Fair Picture of Science

“How Much Turmoil Does the Science Project Cause Families?” reads the tongue-in-cheek science-fair-style poster illustrating parent Susan Messina’s views on science fairs. Her materials list includes: at least 1 grudging parent, half-baked idea of very dubious merit, and procrastination.

ChemClub FUN

I am excited with my student's response to offering an ACS ChemClub at our high school! ACS does a great job of providing materials and ideas for meetings.
