Friday in 4th grade, we explored some egg science. We learned about inertia! I showed students the flying pizza pan - egg drop experiment. Then we explored the strength on an egg. These pictures show a raw egg mounted in clay and two towers of washers the same height as the egg. We added dictionaries until the egg finally collapsed. We got two more dictionaries after the photo was taken, but I thought we better get the photo prior to the collapse! Chickens and engineers both know the value of the arch shape of the egg! Now we do too!
