Using Twitter for a Backchannel Chat During a Fish Bowl Discussion

Lowell Thomson | Sat, 03/29/2014 - 08:14

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.

Complex Ions Lab

This laboratory exercise accompanies the article "A guided group inquiry lesson on coordination compounds and complex ions". The laboratory serves as part of an extended exercise on the chemistry topic of coordination compounds and complex ions. The entire lesson as described in the article also exposes students to how chemical research is conducted and the conflicts and uncertainties that lead to new theories and discoveries.

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 www.compoundchem.com has you covered and then some.

Nail Bottle Demonstration in Slow Motion

Tom Kuntzleman | Fri, 02/21/2014 - 11:27

The nail bottle demonstration is one that many of us have conducted in our classes. To perform this demonstration, 2 – 3 mL of ethanol is placed into a plastic bottle that has two nails punctured into opposite sides of the bottle. After stoppering the bottle, a Tesla coil is touched to one of the nails. A spark jumps from one nail to the other, which initiates the combustion of vaporized ethanol inside the bottle. We recently filmed this reaction with our high speed video camera.

Whoosh Bottle, take 1

My students and I intend to use a high-speed camera to film a variety of chemistry experiments in slow motion.  The first reaction we have decided to film is the “Whoosh Bottle”.  You can read more about this particular experiment in an article in Journal of Chemical Education here.  NOTE:  O

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.
