This demonstration uses a gyroscope (a bicycle wheel works well), string, and a turntable (optional) to show how the equatorial bulge of Earth causes precession. By balancing the spinning bicycle wheel on one hand, and pulling a string attached to the top axle with the other, the axis of the wheel traces out a circle (precesses). The site also explains how the moment of inertia is related to torque ... Full description.

This lesson demonstrates the link between the tilt of the Earth's axis to the plane of the ecliptic and seasons of the year, length of day, effectiveness of sunlight, and polar day and night. It discusses how the inclination of the Earth's rotation axis causes seasons of the year, by varying the length of the local day and the angle at which the Sun's rays arrive on the surface of the Earth, and to ...

In this activity, students will use Moon and tide data from the internet to construct charts and answer questions about the patterns they see. They will be reminded that the Moon has something to do with ocean tides and will discover what the connections are. They will also discover when tides, moonrise and moonset, and phases of the Moon occur. Full description.
