These two activities, from the Royal Observatory Greenwich, involve using the website Galaxy Zoo to classify five samples of ten galaxies. The results are recorded in a table and presented in the form of a bar chart for each sample. These can be drawn on paper or plotted using...

Produced by the Royal Observatory Greenwich, this teacher led booklet gives instructions on using the GalaxyZoo website to investigate the different types of galaxies in the Universe. It uses the context of galaxy classification to develop analysis and statistical skills and requires that the students have access...

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...

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...

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...

Gelli Baff, a crystalline powder, has been dumped into a bathtub filled with water. How can you force the hydrogel to go down the plughole in order to drain the bathtub? 

In this investigation, students learn about swelling reactions, balanced reactions, and polymerisation. Students should be able to...

In this Genetic Futures workshop from the Centre for Science Education and the Biotechnology and Biological Sciences Research Council (BBSRC), students were asked to project themselves 50 years into the future to discover the breakthroughs that advances in DNA...

This Genetic Futures workshop, from the Centre for Science Education and the Biotechnology and Biological Sciences Research Council (BBSRC), provided an opportunity for students to think and talk about the potential benefits and problems of an advance in DNA technology...

This series from the 1960s provided a complete course in general science for 11 to 15 year olds.
