An exercise in science reasoning.

The Egg Drop Activity

Begin Activity

This activity involves observing the results of dropping an egg
onto a surface. The size of the egg, the height from which it is
dropped, and the characteristics of the landing surface can be varied.
The effect of these variations upon the the safety of the egg will be
examined.
The activity is accompanied by a collection of questions that target
your science reasoning abilities. These questions are found in the
widget of this iBook. For convenience sake, they can also be found
online at:
