NASA's Gamma-ray Large Area Space Telescope, or GLAST, is a space-based telescope that looks at the universe in the gamma ray wavelengths. This telescope will study known sources of gamma rays in detail but will also discover thousands of new gamma-ray sources in its five-year mission. This resource has an image of...

More and more local councils are introducing food recycling schemes. This activity, from the Centre for Science Education and the Comino Foundation, looks at the science behind the schemes and encourages students to consider how recycling food and reducing food waste can contribute to sustainability. Students then...

This Nuffield Working with Science unit set out to foster an interest in growing things and to encourage more careful observation of detail with things as familiar as cabbages and tomatoes. Students are required to show a certain amount of practical dexterity, some...

This Catalyst article investigates how plants can be grown in orbiting spacecraft and how this may be useful in future manned space missions.

The article is from Catalyst: Secondary Science Review 2014, Volume 25, Issue 3.

This simulation allows students to pump gas molecules into a box and see what happens as you change the volume, add or remove heat, change gravity, and more. They can measure the temperature and pressure, and discover how the properties of the gas vary in relation to each other.

Sample learning objectives...

These downloadable videos and animations are part of the multimedia package Stuff and Substance, developed by the Gatsby Science Enhancement Programme (SEP). They can be used to develop the ideas relating to the pressure of the gas state and dependence of the boiling...

The Gravity Jet Suits use five small gas turbines to create enough lift for a human to fly.  This resource explains how the gas turbines work, and how this relates to Boyle's Law.

This Catalyst article looks at how you can collect iron micro-meteorites using a magnet. 

The SEP (Science Enhancement Programme) was set up in 1998, by the Gatsby Charitable Foundation, to develop innovative, low-cost resources to enhance secondary science education, and provide support for science teachers. An extensive set of publications was produced including SEP’s range of high-quality...

A Catalyst article explaining how a Geiger counter works through the use of captioned illustrations.

This article is from Catalyst: GCSE Science Review 2004, Volume 15, Issue 1.

Catalyst is a science magazine for students aged 14-19 years...

This is a simple investigation where you connect a Geiger Muller tube to a variable voltage supply. You then place an alpha source in front of it and record the count rate for a variety of supply voltages to see how this impacts the count rate.

A Catalyst article looking at how gel electrophoresis is used in DNA fingerprinting. Gel electrophoresis is used to separate big molecules, in particular nucleic acids and proteins. To learn more about the structure and function of large molecules such as DNA and proteins, they can be broken up into smaller...

Produced by Science & Plants for Schools (SAPS), this activity enables students to look at the gel electrophoresis of DNA treated with restriction enzymes. It will help to develop a knowledge and understanding of the cutting of DNA with restriction enzymes.
