Pictionary Definitions

Posted on

After grading the third unit test, I noticed that my chem classes were using some words that might be considered interchangeable in an English-context, but definitely are not in a science-context. I had them get into groups and come up with visual depictions of the following words: 

  • molecule, atom, ion 
  • energy, bond, charge 
  • chemical, dangerous

The first set of words was pretty useful for them to distinguish between species. The second set was tricky because we haven’t formally defined “energy” yet (but they should remember something from physics last year). And admittedly, the last set really gets my goat, but there were some interesting conversations as I walked around. And a lot of biohazard symbols and crossbones. But not many chemicals-that-look-hazardous, so I’ll count that as a win.
