Explore the effects of gravity on a slowly falling object: a parachute you make out of plastic bags, string and stones.

Learners explore three-dimensional geometric frames including cubes and tetrahedrons, as they create bubble wands with pipe cleaners and drinking straws.

In this demonstration, learners discover that nanoparticles behave differently, in part because they have a high surface area to volume ratio.

In this design challenge, learners will create wind-powered contraptions to transport a load, such as a cupcake or another small object, and test to see if they work.

In this math lesson, learners compare products to determine the best product.

In this lab exercise, learners explore diffusion, cell membranes and particle size using beets and three alcohols.

In this activity, learners compare and contrast their own skin (including the area covered) with that of an orange.

In this two-part activity, learners investigate buoyancy, density and surface area as well as biodiversity and the relationship between the structure and function of organisms.

This lesson focuses on how nanotechnology has impacted the design and engineering of many everyday items from paint to fabrics.

This lesson focuses on surface area and how the shape of sugar crystals may differ as they are grown from sugars of different coarseness.
