After Chemistry Co-op Class, Lacie spent over an hour rewriting her history answers for Chapter 2. Yeah! Did she have her Robinson Crusoe outline? Nope. After lunch, and a search in her history book for all eleven good emperors and all four bad emperors, she asked to work on Chemistry problems and conversions. Since the lion share of our time this past two days has been on Chemistry, why not? This is after spending four hours on Tuesday! In Chemistry class the kids worked on Bowling for Density and Kool-aid—and accuracy and precision. (Here is the Bowling for Density follow-up.). Bowling for Density is homework. Each kid has a different weight of a bowling ball to use to determine its density. I made them up: 11.5, 13.5, 14.5, etc. The kids copied the notes posted on the board.
In any case, Lacie wanted to do the calculations. She asked if the density was 18.9 g/cm3. Nope. But, Lacie identified the problem! She hadn’t converted the circumference from inches into centimeters. That’s progress. The second time, she had a value of 1.3 g/cm3. Yeah! The last part was an explanation of why the ball would sink. She had it! 1.3 is greater than the density of water, which is 1.0 g/cm3.
She did the Kool-aid activity, too. Her pack of Kool-aid is 6.5g. She has to use the recipe for Kool-aid, but reduce all of the proportions to one three ounce cup. She did it! Yes, it took an hour. So, we did not do any Algebra today; instead, we spent the afternoon doing more conversion problems. We used this one. After she corrected her answers (17/20), Rob and I made our own conversion problems based on the ones she missed. We added a few English to Metric conversions with the unit factor method.
I reminded her to finish the I Am paper for Theology and the outline for Robinson Crusoe. Next week is a new day and time. With any luck, we’ll start Latin Tuesday.
