Egg-citing Physics
Produced by the Institute of Physics, this Physics to Go video shows a short demonstration that can be used to engage your students. The teacher notes include the equipment needed, tips and contain a full explanation of the physics involved.
Spinning hard-boiled and uncooked eggs demonstrates momentum.
The raw egg is filled with liquid whereas the hard boiled egg is effectively a solid. The hard boiled egg is easier to spin since the entire egg starts spinning at the same time, whereas in the raw egg only the outer shell is spinning at first, and gradually the liquid insides begin to spin as they are dragged around by the shell.
Stop the hard-boiled egg and it stays stopped. Do the same with the raw egg and the spinning contents make it mysteriously start turning again.
HEALTH and SAFETY
Any use of a resource that includes a practical activity must include a risk assessment. Please note that collections may contain ARCHIVE resources, which were developed at a much earlier date. Since that time there have been significant changes in the rules and guidance affecting laboratory practical work. Further information is provided in our Health and Safety guidance.
