Just the other day within my IB Chemistry HL classes, we were discussing the color of transition metal complex ions in solution. It's a bit imperfect, because they are not yet dissolved, but I set up a number of metal chloride salts in order to help students see the pattern. They are arranged according to the position of the metal in the periodic table. It ends up being quite obvious to the students that the only metal salts with color are in the d-block. I'm now in the process of ordering more chloride salts so I can complete the pattern even more the next time I teach this topic.
In my previous post, I shared the general formatting of the videos I create for my IB Chemistry course within which I utilize the flipped model. Within that blog post, I mentioned that I use Google Forms to collect data about the videos, and I'd like to offer some thoughts on this as a tool with many uses.
Deanna Cullen wrote about her decision to move forward with a blended model this year and asked for some suggestions about videos. I've been using videos as a teaching tool in my class for the last six years and wanted to share some thoughts.
If you are like me and unable to attend BCCE 2014, there is still a way to be part of the action. Twitter! Even if you don't have a Twitter account, you can follow tweets from participants that are there "live tweeting" the action.
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.
