A worksheet (cloze activity) is included about the Titanic disaster and forces on the ship.

The resource combines a bit of Christmas with the following physics topics; acceleration, vector addition of forces, Newton's third law, air resistance, distance-time graphs, velocity-time graphs, parachutes, resultant forces and Newton's second law.

This resource is designed for lower ability students. It would work well with some background video about the Apollo 11 Moon Landing. Key points are that gravity is a force attracting all masses together. Gravity pulls us towards the centre of the Earth and keeps the Earth in orbit around the sun.

This resource was designed for lower ability students. It deals with Galileo's invention of the telescope and subsequent discovery of Jupiter's four largest moons. The worksheet is designed to help students understand the link between orbital period and strength of gravity.
