In this physics activity (page 14 of the PDF), learners gain a better understanding of how friction and mass affect objects by comparing the rotational inertia of raw and hard-boiled eggs. Although this was created as a post-visit activity for a workshop about the physics of roller coasters, it also makes an excellent stand-alone activity.
