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 measure the diameter of their water balloons, model an impact, measure the diameter of the “crater” area, and determine the ratio of impactor to crater.

In this math lesson, learners predict, interpret, and sketch graphs of functions related to the shapes of bottles. A measure of water is poured into a container.

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.

This activity (located on page 3 of the PDF under GPS: Balloon Fiesta Activity) is a full inquiry investigation into Bernoulli’s principle and airplane wings.

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 math activity related to volume, learners use problem solving skills to calculate and build a model house for Minus the dog.

In this activity, learners help create and then navigate an outdoor course of the traditional "planets" (including dwarf planet Pluto), which are represented by small common objects.

In this activity, learners build edible models of Jupiter and Earth to compare their sizes and illustrate the planets' internal layers.

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 investigate how geometry plays a role in perspective.

In this activity, learners model the gravitational fields of planets on a flexible surface.

In this activity, leaners explore building techniques by recreating the story of The Three Little Pigs.

In this experiment, learners design and build a model room in a shoebox and furnish it with tiny furniture.

In this demonstration, learners compare the relative sizes and masses of scale models of the planets as represented by fruits and other foods.

In this activity, learners work in teams to investigate the relationship between mass, acceleration, and force as described in Newton's second law of motion.

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 evaluate the potential performance of air rockets placed inside a wind tunnel.
