This practical activity uses a simple and convenient model of the real environment in order to demonstrate the principles of random sampling and how to estimate biodiversity. Students use different coloured sugar balls to represent different species in order to put Simpson's Diversity Index to the test, which takes...

A Catalyst article about a Kenyan scientist who is searching for better treatments for malaria, a disease which kills more than a million people in Africa each year. The article also explains some of the challenges of doing science in Africa, where funding is low. Often the illness shows a remarkable ability to...

A Catalyst article about ants. A colony consists of hundreds, even thousands, of ants working diligently and cooperatively, perhaps to kill and carry a large prey item, build a large nest structure or develop and use road-like networks for foraging.

In this resource students are asked to measure dimensions from scale drawings and find the areas of rectangles and triangles. They then calculate the amount of paint needed to paint a house and its cost.

The resource is part of the Nuffield Maths Level 1 Foundation resource collection.

The animal kingdom contains an abundance of exquisite natural patterns from the stripes of an angelfish to the spots of a leopard. But how do these arise during early development? This Catalyst article looks at Turing mechanisms as a way of explaining how patterns develop as an animal grows.

In 1952, Alan...

Astro Pi is the name of a small computer developed by the Raspberry Pi Foundation, in collaboration with the UK Space Agency and the European Space Agency (ESA).

There are two very special Astro Pi’s. Their names are Ed and Izzy, and they have been qualified for spaceflight. They are now onboard the...

Produced by the Industrial Trust, Business & Education South Yorkshire and JIVE (Joint Interventions), this leaflet identifies hints and tips to help organisers of visits to industry. Often organisations that are prepared to offer industrial visits to their sites are unaware of the action they can take to make...

This guide has been written to support teachers and technicians who would like to build a combat robot. It describes:

• a range of different types of robots that you could make, discussing armour, weaponry, drive and control.
• advice for the design process
• health and safety...

This research was Published in 2014 and presented at the ESERO 2013 Conference.

The purpose of any teacher continuing professional development (CPD) is to ensure a positive change in pupils’ outcomes, yet the evaluative evidence to support this relationship is often weak or missing. Using the CPD programme...

Climate Ambassadors can help your nursery, school, college or MAT develop a climate action plan for free. They can help you take the first step in getting started or help you develop your plans and put them into action.
