Testing Falling Peanut Butter Sandwich Myth

In this activity related to rotational inertia (page 1 of the PDF), learners will use a bit of scientific experimenting to test if open-faced peanut butter sandwiches really do always land peanut butter side down. Learners will also test other variables, such as drop height, size of bread slice, and whatever else learners can think of, to arrive at some sound conclusions. Relates to the linked video, DragonflyTV: Microgravity.
