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

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

In this activity, learners use measurement concepts to make models of what their body parts might look like if they were a snake or a chameleon.

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 related to Archimedes' Principle, learners use water displacement to compare the volume of an expanded gummy bear with a gummy bear in its original condition.

In this math activity, learners pretend there is a special store that lets you pay for toys by their height in pennies.

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).

In this activity, learners use two different techniques to estimate how many little things fit into one bigger thing.
