In this video, students are competing to design a container that can protect an egg from breaking when dropped. The students were allowed 30 plastic drinking straws, 1 meter of string, and 1 meter of tape to complete their designs. The eggs were then dropped from increasing heights, and the last one left intact won. The project is designed to look at the Law of Conservation of Momentum which means as length of impact (i.e. the more padding it has) increases, force on the egg decreases, thus the egg has a better chance of not cracking as the padding increases.	In this video, students designed and built bottle rockets using 2 liter pop bottles. The students used construction paper and poster board to construct the fins and nose cones of their rockets. The rockets then had a premeasured amount of water placed in them and were pressurized to around 45psi. When the string is pulled the pressure is released and the rocket launches into the sky. This project is designed to look at Newton's Third Law of Motion: for every action there is an equal and opposite reaction. The action is the pressure being released; the reaction would then be the rocket lifting off.
