Black Hole Mathematics

This series of activities from NASA take a mathematical approach to looking at black holes. They are intended as supplementary problems for students looking for additional challenges in the maths and physical science post-16 curriculum. Problems consist of a student page and an answer sheet. Students need to be...

The Hammer and the Feather on the Moon

This classic Apollo 15 clip, from Footagevault, demonstrates that the mass of an object does not affect the time it takes to fall when dropped in a vacuum. The clip could be used in Key Stage Three and Four lessons on forces.

Spaceflight History: First Spacewalk

Produced by FootageVault, this original NASA video shows America's first spacewalk, made by astronaut Ed White, from his Gemini IV spacecraft on the 3rd of June 1965. The spacewalk lasted 23 minutes, during which time the astronaut manoeuvred using a hand-held oxygen-jet gun to push himself.

Cooking a Comet

Comets are considered to be time capsules containing information about the conditions of the early Solar System. In order to understand what comets are, where they come from, and their influence on the evolution of Earth, it is necessary to find out what material they contain. This teacher demonstration and student...

Marble-ous Ellipses

In order to understand the orbits of planets, comets and other celestial bodies, it is necessary to examine the principles of how gravity, and the velocity of an object, interact to produce an orbit. It is a common misconception among students that planetary orbits are circular. This practical activity gives a...

Measurements with the Sun

Measuring the diameter of our star This simple exercise allows students to measure the diameter of the Sun using a metre rule and two pieces of card. An image of the Sun needs to be projected on the card using a small hole in one piece of card.

Measuring the number of hours in a day...

Solar Tornadoes

This resource uses the context of tornadoes in the solar atmosphere to investigate circular motion and energy changes. A hole is drilled in the bottom of a washing up bowl and orange pith can be used to track the motion of the water when draining through the bottom and creating a vortex. The Key Stage Three...

Training in Space

In this activity pupils will be able to discuss various ways of simulating gravity in space and the importance for maintaining a healthy body for the return to Earth. Working in teams of four, pupils should choose their favourite exercise or sport and adapt it for space. They should identify the forces required for...

What Keeps Us Stuck to the Earth?

Alice wonders why we don’t float out into space. Their thoughts lead on to the idea that gravity is an acceleration and that they may need Einstein’s ideas of space-time to explain why they are accelerating. This clip could provide a lead in to topics such as relativity, acceleration and gravitational force. 

Special Relativity

This animated clip describes Einstein’s theory of special relativity: if the speed of light is constant then time and space must be experienced differently, depending on the observer. Richard Feynman showed how this can be proved using a moving light clock compared to stationary clock.
