This was a busy week in the Lower School Science Lab. The 2nd graders learned about the process of photosynthesis, and discovered the reasons why leaves change color in the fall. They did a lab called "Hidden Treasure" where they found out thatcolors can be covered up or "hidden" by other colors. The 3rd graders finished their study of leaves by testing the toughness of leaves using a tool called a "penetrometer". They were back for a second lab where they looked at roots and compared and contrasted tap roots and fibrous roots. The 4th grade classes are beginning their study of "Alien Invaders" in Lake Michigan.
