Review Those Graphing Skills!

Students can always use extra practice reinforcing their graphing skills.  And, as end of course testing gets closer and closer, this is the perfect time for a quick review.

This is a free lab activity that uses a balance and metric ruler to measure the area and the mass of small pieces of poster board.  The relationship between area and mass is graphed.  The graph is then used to determine the area of irregularly shaped pieces of poster board.
