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

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.

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

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

In this activity, learners build a 1:140 "scale model" of NASA's X-33 Reusable Launch Vehicle (RLV) Technology Demonstrator, and investigate how the model dimensions compare to the real vehicle.

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

In this activity, learners construct hand-held altitude trackers. The device is a sighting tube with a marked water level that permits measurement of the inclination of the tube.

In this activity, learners create virus models, including nucleic acid and proteins, using simple materials. This resource includes information about virus structure and gene therapy.

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

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.

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

In this activity, learners watch a video to learn about a couple who built a home out of shipping containers in Brooklyn, New York.
