Cosmological Redshift
Students use the Doppler formula to calculate the redshift of a distant galaxy and the size of the Universe when light first left the galaxy. Accompanies the video 'How big is the Universe?'.
Learning resource
Conservation of Momentum
In this practical activity students explore how momentum is conserved when two objects collide.
Learning resource
Compasses and Magnetism on Earth
In this practical activity, students investigate magnetic materials, attraction and repulsion and make a magnetic compass. Accompanies the video ‘Seeing The Invisible’.
Learning resource
Colour and Wavelength in Space
An activity to motivate or reinforce learning about the electromagnetic spectrum in which students compare and contrast views of the Sun and the Milky Way Galaxy in different wavelengths of light.
Learning resource
Celestia Navigation
Celestia is a spaceflight simulator that allows you to explore real astronomical data as you fly through space.
Learning resource
Calculating where Space begins
In this classroom activity students use real data with the physics of forces and circular motion to calculate the altitude at which space begins.
Learning resource
Calculating the Size of a Black Hole
Students calculate the Schwarzschild radius of a black hole with the same mass as the Earth and one with the mass of the Milky Way. Accompanies the video 'What's inside a black hole?'.
Learning resource
Calculating the Mass of the Sun
Students use Kepler's 3rd law and Saturn's orbit to calculate the mass of the Sun. Accompanies the video 'How do we know how old the Sun is?'.
Learning resource
Calculating the Energy Output of the Sun
In this activity students use Einstein's most famous equation to calculate the amount of energy released from nuclear fusion reactions in the Sun. Accompanies the video 'How do we know how old the Sun is?'.
