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 lab exercise, learners explore diffusion, cell membranes and particle size using beets and three alcohols.

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 activity, learners compare and contrast their own skin (including the area covered) with that of an orange.

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.

Get all wrapped up in a lesson about skin!

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