Can a Mouse Lift an Elephant?

Read Just a Little Bit, by Ann Tompert as an introduction to levers. Discuss playground seesaws and then turn learners loose to experiment with the placement of a fulcrum. Their goal is to determine where to place it in order to lift ten pounds. Cross curricular activities are suggested, including the graphing of the data collected. This is a terrific activity to use when teaching about simple machines.
