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 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 two-part activity, learners investigate buoyancy, density and surface area as well as biodiversity and the relationship between the structure and function of organisms.

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.

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