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

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.

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

In this activity, learners explore scale by using building cubes to see how changing the length, width, and height of a three-dimensional object affects its surface area and its volume.

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

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

This hands-on activity demonstrates how a material can act differently when it's nanometer-sized.

Get all wrapped up in a lesson about skin!

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