Innovation in the Classroom: An Egg-celent Design

Students in Ms. Tyro’s Physics class are currently studying momentum and collisions. For a real life connection, they watched videos about early seat belt testing in the automotive industry. This testing utilized eggs as crash dummies in tiny carts.
In pairs, students tried their hand at designing egg carts that would protect an egg during a trip down a ramp and collision with the floor. Their focus was either increasing the time over which the impact occurred or reducing the force applied. They used everyday materials such as foam, socks, felt, packing and duct tape to secure their eggs in silicone trays. They then had to reduce the friction on the tray by adding tape or fabric to the bottom so it would slide down the ramp. Some even encased their whole carts in a sock and decorated it.
Out of six carts, only one allowed the egg to crack slightly. Students were then challenged to reduce the padding materials by half but still find a way to protect their egg. These tests were also successful! Throughout the experiment, data was collected including mass, time, and distance. Students then analyzed their results by calculating the velocity, acceleration, momentum and impulse their eggs encountered.
Students enjoyed the opportunity to create something new with a goal in mind. Their creativity showed as they re-purposed simple materials to accomplish their task.
