Doug Ragan been using magnets of elements and subatomic particles for some time to help his students visualize what is happening at the particle level of chemistry. Download the files attached to the post and print out your own set of elements and particles!
Near the end of the school year we are all thinking about what we will do with our AP Chem students until the end of the semester. Last year I wrote about a post AP independent study activity that I use dealing with transition metal compounds. I still like it and use it. But this year I want to talk about a very involved lab that many of my colleagues are ignoring.
A few weeks ago, I presented at ChemEd 2013 "Flipping with Chemistry Apps". One app that I use in my HS chemistry class on the iPad is the app Building Atoms, Ions, and Isotopes HD Lite.
