Have you been watching the Winter Olympics? I have been able to draw many similarities and relevance to what I am teaching in the classroom. How about you?
In a dramatic movie trailer voice: “The Boiling Point. Gone without a trace. Or were they? The scene… a mystery. Had they disappeared? Been broken up into unrecognizable pieces? Can our hero find the answer? Or will it be too late?”
Every year when the day came to discuss the rules for significant figures in measurements with my classes I would write the rules on the board, we’d work through a couple examples, and I’d try to find a way to explain why we needed to use them when reporting measurements. This has never been my favorite topic to teach, mostly because I had a difficult time helping students see why these rules for measurement and reporting uncertainty were important.
Making plans for back to school? Don’t forget the candy! It doesn’t sound like something a nutritionist would recommend, but what about a chemistry educator?
