Produced by Twig, this animated video is a clear and accessible explanation of how the Solar System fromed. The video describes how:

* the solar system grew from a ball of gas which formed the Sun

* gravity caused heavy material to cluster together and eventually form planets

* the inner...

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...

Black holes provide an important tool for testing the fundamental laws of the universe. This resource from the Institute of Physics, looks at the extreme physics associated with black holes, how we can spot them, and what roles they may play in galaxy formation.

This guide looks at stellar black holes and...

A pair of videos that investigates the Boyle’s law relationship. The first demonstrates how to undertake the experiment using a pressure sensor and syringe.  The second explains how to interpret the data, plot the graph and determine if there is a relationship between the volume of a gas and the pressure.

Brighton Energy Co-op recently installed Brighton’s second-largest solar system on the roof of Shed 3a at Shoreham Port. Since May 2013, 800 panels have covered the two sides of this 3000 m2 roof: half face east, the other half west.

This activity pack, managed by the British Science Association, supports the theme "Our Diverse Planet" for British Science Week (although it can be used at any time). The activities are arranged in three groups titled Diverse Jobs, Diverse People and Preserving Natural Diversity; each group describes four...

This resource, produced by SEPNet and Queen Mary University of London, uses Lego to represent the building blocks of matter. Different colour Lego bricks are assigned to different quarks and leptons. The quarks can be put together to make hadrons, such as protons and neutrons. The blocks can also be used to show...

In this activity, students create colour images from satellite data. This allows them to study how different surfaces reflect different wavelengths of light, how coloured images are created using an RGB model, and how band combinations can be chosen to examine a particular landscape effectively.

This Catalyst article explores the processes undertaken during the construction of a white water canoe course for the Olympic Games which requires a huge range of practical skills, but also great science skills too. The scientist must calculate how much noise from both the course's construction and its use during...

A Catalyst article about a visit to CERN, the particle physics lab and what the centre has to offer a science student by way of a case study.

This article is from Catalyst: GCSE Science Review 2007, Volume 17, Issue 4.

Catalyst is a...

This is a CPD taster created to give teachers a better understanding of what to expect when joining one of our secondary science courses. Below you will find a video and a task for you to do in your own time. Once you have done the activity, ...
