Ratio of Surface Area to Volume
This lab is designed to help students understand how nanoparticles may be more effective catalysts by investigating how the surface area-to-volume ratio of a substance is affected as its shape changes. Resources include a Teacher’s Preparatory Guide, Part 1, Part 2 as well as a Student Worksheet and Guide, Part 1 and Part 2 .
The purpose of this lesson is to help elementary students extend their knowledge of area, perimeter, and volume to include surface area. Resources include a Teacher’s Preparatory Guide as well as a Student Worksheet .
