This lesson focuses on how materials behave differently as their surface area increases.

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

Learners display their findings after a study of surface area and volume. They build a mobile to show a commercially available box and a constructed cubical box of the same volume.

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.

This simple, yet surprising physics demonstration challenges preconceptions about forces, and demonstrates the strength of atmospheric pressure.

This investigation provides learners with a hands-on activity that simulates the changing relationship of surface areas-to-volume for a growing cell.

This is an activity (located on page 4 of the PDF under Surface Area Activity) about surface area and reactivity.

Learners investigate how temperature affects the rate of chemical reactions by observing how steel wool reacts with various types of Kool-Aid solutions at different temperatures.

In this activity, learners use simple materials to create giant bubbles.

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

In this activity, learners explore the chemical reaction between water and effervescent antacid tablets. This hands-on activity models how a material can act differently when it's nanometer-sized.

In this chemistry demonstration, learners investigate the factors that increase the rate of dissolution for a solid.

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

This lesson focuses on how nanotechnology has impacted our society and how engineers have learned to explore the world at the nanoscale.

In this physics demonstration, learners are challenged to insert a straw the furthest into a potato.

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.

Learners determine the surface area and volume of two identical boxes, and then figure out the dimensions of a cubical box with the same volume.
