The purpose of this lesson is to help students extend their knowledge of area, perimeter, and volume to include surface area. The understanding of these concepts begin in the elementary grades and helps students understand events such as why a hot potato cools down quicker when it is spread out in smaller pieces and why a cell is triggered to divide. This understanding is even more important when students begin to understand the micro and nano scales in middle and high school.
- Nanometer-sized things are very small, and often behave differently than larger things do.
