Today’s class is devoted mostly to the Sinking and Floating unit, with additional time to take plant measurements and discuss LTRP questions and progress.

 

Sinking & Floating (need clay, tubs, water …):

 

          Tell students about potential quiz questions for the unit re: floating/sinking fruit, floating/sinking soda pop cans [YouTube video with floating/sinking orange: http://www.youtube.com/watch?v=J8aReMgjMto].

·         Get a piece of clay to float. Keep track of shapes that did and didn’t float well. Get clay to float while holding load=its weight. Look for patterns differentiating the two groups.
