As I headed over to my blog dashboard, I realized it has been almost exactly a year since I last posted. And, funny enough, I am exactly where I left off. I am back at Taft School, this time for a two-week AP chemistry workshop. The main difference is this time I actually will be […]

All textbooks are not created equal (though a few are very similar) As is typical in these sorts of workshops, I ended up with about 500 lbs of free textbooks. In addition to the typical (Zumdahl, Brown/LeMay) I got to look at a few that I hadn’t heard of or considered before.  My favorite among […]

Drop Counters are AWESOME. When given the choice between spending 20+ minutes manually entering volume data every 1 mL, or sitting back and watching it the data graph itself in 3 minutes or less, I’m going with the latter. Not only does the data come out great but it frees up the students to actually […]

There’s a lot of AP-level chemistry in a simple 4-ingredient baggie lab. Calcium chloride. Sodium hydrogen carbonate. Phenol Red. Water. A common first year chemistry lab, but incredibly useful in third quarter of an AP chemistry lab. Dissociation, hydrolysis, precipitation, neutralization reactions, thermodynamics, net ionic equations. Inquiry. Its all there. And its cheap. And its straight-forward […]
