Disney’s animated movie, Tangled, comes out next week. We’ve shown students some of the Brothers Grimm’s original fairy tale along with giving them a glimpse at the physics involved in the animation of Rapunzel’s hair. Ratios are needed to estimate the weight of our own hair given the weight of Rapunzel’s 70 feet of hair. Number sense is our goal here. Can your students convert from meters to feet and figure out the length and weight of the world’s longest haired woman?
