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

In this activity, learners perform 20 arm curls with cans that simulate the weight of beans on Earth versus the weights of the same number of beans on the Moon and in space.

In this activity, learners explore the engineering design process and the basic mechanics behind building bridges as they build one themselves using gumdrops and toothpicks.

Learners work in groups to construct bridges using stale marshmallows and toothpicks.

In this activity, learners conduct a waste audit and use their findings to implement a plan for reducing trash.

Learners play the role of materials engineers as they test the flexibility of different materials.

In this activity, learners make mobiles to explore the concepts of balance, counterbalance, weight, and counterweight.

This activity was designed for blind learners, but all types of learners can utilize it to investigate volume, mass, and density.

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 math lesson, learners use fruit to learn about proportions and percentages. Learners compare the weights of the edible and non-edible portions of fruit.

In this activity, learners will test cups full of potting soil, sand, and sphagnum moss to see which earth material is able to soak up the most water.

In this activity (page 1 of the PDF under SciGirls Activity: Bogs), learners will test cups full of potting soil, sand, and sphagnum moss to see which earth material is able to soak up the most water.
