This fun and simple hands-on astronomy activity lets learners build a scale model of the universe with little more than adding machine tape.

In this activity, learners use rice grains to model the composition of the atmosphere of the Earth today and in 1880. Learners assemble the model while measuring percentages.

In this activity, learners create a model using metric measuring tapes and atmosphere composition data.

In this activity, learners evaluate the potential performance of air rockets placed inside a wind tunnel.

In this activity, learners work in groups to design a parachute out of household items that keeps an egg secure when dropped from a certain height.

In this activity, learners make a model of a pollution spill that occurred at Bangs Lake in Mississippi and measure water quality parameters in their model.
