All rights reserved. We have completed the third week of instruction in the new semester. My sixth and seventh grade students have been working with experiments from the FOSS Variables kit. Week before last, they experimented with pendulums. I had them write up their conclusions, and discovered they really hadn't kept very good records of their results, and most of them had a hard time making much sense of what they had done.
