Young Explorers Chemistry and Physics: Displacement and Volume

Our little household is doing Chemistry and Physics this summer with Paul, ten.  Ordinarily, he goes to camps and VBS—all canceled.  We are doing a few hours of School every day.  Paul did the volume Try-it in Lesson 1.  My husband, Rob, added the calipers.  Paul measured volume of several objects by displacement and by direct measurement with calipers.  This activity is more of a lab.  It even has a hypothesis.  Which method is more accurate.  Paul measured several objects both ways.  He wrote up the lab in the Notebooking Journal.  Scan a copy of the lab for your digital portfolio.
