So we splurged and got the little kits containing ziplocs of common chemicals, test tubes and pipettes. We had some of that stuff, but the package deal was so simple.
We're both really impressed with the task-oriented teaching in the units. Fiona has just about finished the first of the four units, the one on chemical analysis. It's described as being suitable for Grades 5-10, and though it's perfect for Fiona, I think it would be a pretty light-weight program for a high schooler. Still, it's far more in-depth and sensibly, workably hands-on than similar programs I've seen.
Pictured above is her red-cabbage-water indicator at various pHs. From left to right: pH=3 (with vinegar), pH=6 (with a single drop of vinegar) pH=6.5 (straight cabbage water), pH=9 (with kitchen cleanser) and pH=13 (with lye).
