Mrs. Carpenter’s 7th grade students were studying cause and effect by being given a huge container full of “stuff”.  Their assignment was to cause at least 3 different things to happen in order for a certain effect to occur.  2 different groups worked on this project in 2 different ways.  I didn’t get to stay to see the end result, but both groups were well on their way to a successful conclusion when I wandered over to see other students working on Newton’s Laws.
