In this Engineering Design Challenge activity, learners will use balloons to investigate how a multi-stage rocket, like that used in the Interstellar Boundary Explorer (IBEX) mission, can propel a sat

In this activity, learners sort different natural phenomena into categories (they occur on Earth, on the Moon, or on both), and then model how energy moves during a quake using spring toys.

In this activity, learners create 3D geometric shapes using straws and pipe cleaners.

In this activity related to Newton's Laws of Motion, learners build a boat powered by a propeller in the air.
