Curriculum-linked learning resources designed to work in the classroom.
A classroom activity in which students use Hubble’s law to derive the age of the Universe and consider the assumptions and sources of error associated with this calculation.

In this video, Royal Observatory Greenwich astronomer Radmila demonstrates how the Doppler effect can be applied to finding planets orbiting distant stars in our galaxy called exoplanets. She carries out a short demo from which data can be collected and analysed and explains how these techniques can be applied to light and the hunt for exoplanets.

A classroom activity with instructions to accompany the video 'Alien worlds and the Doppler effect'.
are there aliens
Life began on the Earth around 3.5 billion years ago. Could life have evolved on other planets and if so where are they? Astronomers at the Royal Observatory Greenwich explain how we might detect them in this video.

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?'
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.

On the smallest to the largest scales, collisions and explosions happen all over our Universe.

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?'
how big is the universe
Royal Observatory astronomer Liz shows us the expanding nature of the Universe and how this affects the light reaching us from distant galaxies, some of which will remain forever hidden from our view.
how do we know how old the sun is
ROG astronomer Brendan explains how we determine the age of our Solar System from space rocks and how we can work out how long the Sun has left before it engulfs the inner planets.
