Cookie Surface Area

This is an activity (on page 2 of the PDF) about surface area to volume ratio. Learners will bake sugar cookies, testing how much colored sugar is rolled up by 1 large ball of dough vs. an equal amount of dough divided into 20-25 small balls. Surface area to volume ratio is an important concept in nanotechnology because it helps explain why the same substance can behave differently when broken into nanosized pieces. Also relates to linked video, DragonflyTV Nano: Surface Area.
