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

This is an activity (located on page 4 of the PDF under What's Nano? Activity) about size and scale.

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 investigate the relative growth of lengths, areas, and volumes as cylinders are scaled up.

This is an activity (located on page 3 of PDF under Gecko Feet Activity) about modeling a nanoscale phenomenon (gravity-defying gecko feet) with macroscale objects (shoes).

This lesson focuses on how to measure at the nanoscale and provides learners with an understanding how small a nanometer really is.

This is a quick activity (on page 2 of the PDF under Gecko Feet Activity) about the forces of gravity and surface tension and how their behavior is influenced by size.

In this quick activity about size and scale (on page 2 of the PDF under What's Nano?

In this game, learners explore the different sizes of things in the world. In this Twister-like game, learners must place a hand or foot on a circle of the right scale - macro, micro, or nano.

In this activity, learners explore how spring scales work and how they are used for non-exact weight measurement.
