In this activity related to microbes, learners create scale models of microorganisms and compare relative sizes of common bacteria, viruses, fungi and protozoa using metric measures: meters, centimete

In this activity, learners will measure their lung capacity by making their own spirometer. Learners will then explore factors that affect the amount of air the lungs can hold.

In this activity, learners simulate what happens to a human spine in space by making Sponge Spool Spines (alternating sponge pieces and spools threaded on a pipe cleaner).

In this activity, learners take measurements and create charts to learn about the size of dinosaurs and their relative scale to humans.

In this activity, learners explore dinosaur skeletons and anatomy. Learners make observations about a T. rex skeleton diagram and then measure the skeleton length and width.

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 investigate how geometry plays a role in perspective.

Learners build models to learn about the special cells and structures that plants use to move water from their roots up through the stems and leaves.

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.
