Class practical: Tracking the motion of the Sun through the sky for a day, month or year.

Practical Activity 14-16

Class practical: observations of the stars, planets and the Moon for students to make.

Practical Activity 14-16

Demonstration: a home-made planetarium.

Practical Activity 14-16

Demonstration: the apparent motion of the Sun and planets around the Earth, including epicyclic motion.

Practical Activity 14-16

Demonstration: simple model to demonstrate the ‘flattening’ of the poles as the Earth rotates.

Practical Activity 14-16

Demonstration: this demonstration imitates the Earth’s precession, with a spinning flywheel ‘rocked’ by the pull of a taut...

Practical Activity 14-16

Demonstration: Using the model celestial sphere to show the precession of the equinoxes.

Practical Activity 14-16

Demonstration: to show how the spin axis of the Earth rotates or precesses.

Practical Activity 14-16

Demonstration: using a scale drawing to predict the time for a satellite close to the Earth. The results can later be compared...

Practical Activity 14-16

Demonstration: angular momentum is conserved when the radius of orbit is changed.

Practical Activity 14-16

Demonstration: observe the behaviour of light from a point source. Develop the idea of an inverse square relationship and then...

Practical Activity 14-16

Demonstration: a simple model to show how Copernicus explained the looped paths of the outer planets.
