Science Fair - Conservation of Angular Momentum>>  Click to open

This provides a synopsis of my sister's 4^th-grade science-fair project. Presented in March 2003, she chose the conservation of angular momentum as her topic. With the help of her older sister as a model and assistant, the hardware, photos, and movies were taken as data for the experiment.

Below are pictures of the project with a movie showing the conservation of angular momentum in action with a brief explanation.

Construction
		Materials: Bicycle wheel Wheel pegs Two circular boards Ball-bearing rings Wood screws
Materials	Wheel
Purchase of the hardware	Fabrication of the platform	Assembly of the wheel

Experiments
Spin A 1	Spin A 2	Spin A 3
		Spin A A lighter subject rotates more ... Spin B than a heavier subject.
Spin A 4	Spin A 5
Spin B 1	Spin B 2	Spin B 3

Movie
		The conservation of angular momentum states, that the total angular momentum before an event will be equal to the total angular momentum after the event. When the wheel is inverted, the system maintains constant angular momentum by rotating the subject in the opposite direction.
