Produced by Practical Action, these materials contain ideas and support for students undertaking a CREST award. There are stimulus materials that help students look at an issue of sustainable development. These materials look at provision clean and reliable drinking water. It looks at sustainable systems such as...

This infographic for post-16 students explains the different methods of speciation by natural selection. It summarises allopatric and sympatric speciation 

This activity is part of Endeavour, an online collection of inquiry-based teaching resources created by experts...

This resource supports Year 5 pupils to understand how flowering plants reproduce. Pupils are given the opportunity to revise their Year 5 science learning with an active starter and then the PowerPoint presentation and supporting resources support pupils to build on this, helping them to understand the process...

Introduction to the Grand Challenge resources

Following the successful rendezvous of the Rosetta spacecraft, with comet 67P, this Catalyst article explains how a smaller spacecraft will land on the surface of the comet. Philae is due to land on the comet on 12 November 2014, the first ever attempt to land an object on the surface of a comet.

The article...

A Catalyst article about biologists looking for patterns in the distribution of barnacle species on the sea shore. Barnacles are arthropods which live as tiny larvae in the sea and then cement themselves, head down, on suitable rocks, build a shell, poke their legs out of the top of it and start to filter feed. The...

These diagnostic questions and response activities (contained in the zip file) support students in being able to:

• Use observations to determine whether a substance is in solution.

• Recognise that a compound has properties (including solubility) that are distinct from its...

These diagnostic questions and response activities (contained in the zip file) support students in being able to:

• Recognise that stirring does not affect the solubility of a substance.

• Recognise that increasing the volume of solvent does not increase the solubility of a substance...

In this computer science lesson students are introduced to encryption. They model the way that information is transmitted by the internet and try and protect their messages using different keys. Light - there's more to it than...

A National Strategies teacher study unit booklet for science subject leaders, science teachers and higher level teaching assistants on intervention ideas and revision techniques to offer groups of students short-term help to cover what they have missed or address...

As the need to find alternative cleaner forms of energy increases, scientists are looking to technologies, such as Hydrogen Fuel Cells (HFCs), as a power source for transportation.

This Catalyst article explains how hydrogen and oxygen gas can be used in a redox reaction to produce electricity, and the...

These diagnostic questions and response activities (contained in the zip file) support students in being able to:

• Describe the magnetic field created by a current carrying wire.
• Describe the force acting on a current carrying wire in a uniform magnetic field.    
• Explain how a coil of...

Palaeontology strives to discover evidence so that we might learn more about the fossil remains of life and understand how they lived, functioned and even died. Scientists at The University of Manchester have been using state-of-the art imaging, chemical analyses and computer modelling techniques to study the...

This Catalyst article explains how scientists came to understand plants' sensitivity to external stimuli and their ability to move. Mimosa pudica...
