Curated OER
Why is There a Tidal Bulge Opposite the Moon?
Students simulate how the Moon causes ocean tides. In this earth science lesson, students calculate gravitational acceleration using a mathematical formula. They compare the force of attraction between the Earth, Moon and Sun system.

Topsy Turvey Tides
Pupils explore ocean tides. They research how the sun, moon and earth affect the tides. Students draw a diagram illustrating low tides and high tides. They discuss the affect of gravitational pull on the oceans.
