Activity Description

Balloon Scale Model

Students use a ping pong ball, string and balloons to create a scale model of the Earth, Moon and Mars. The scale model is accurate for both the size of the objects and the distance between them.


This lesson introduces students to the science behind landing a rover on the surface of a planet. The science is presented both through Newton's Laws and Conservation of Momentum, so that you use what fits best in your course. Next, the lesson introduces students to the engineering design process that they can use to develop an entry, descent and landing system that will protect an egg.
