Produced by the Charles Darwin Trust, the activities in these materials help students to consider biodiversity within a habitat. To observe change over time, in 1846 Darwin planted a hedge at Down House. Twenty years later, he surveyed the hedge and recorded those species that had disappeared and new plant arrivals...

This STEM activity supports pupils to be able to describe how a deciduous tree changes with the season. This activity, which needs to be carried out over a school year, gives pupils the opportunity to record the changes in a deciduous tree within the school groups. Pupils could draw pictures, use photographs or...

This learning episode, from the Institute of Physics, helps students understand how capacitors charge and the concept of capacitance. Students investigate the relationship between charge and potential difference across a capacitor.

This resource explains what a salt marsh is and how they record sea-level changes. As salt marshes are zoned by tidal inundation, salt marsh plants and sediments can then record changes in sea level as the zones move horizontally in response to vertical changes in sea level.

In a practical experiment,...

This activity, from the Institution of Engineering and Technology (IET), introduces students to how we use sensors in a circuit that will make decisions.

The resource is designed so that students will:

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 idea that some crystals incorporate water molecules within their structures....

In April 1983 the Steering Committee of the Secondary Science Curriculum Review published a consultative paper Science Education 11-16: proposals for ac...

The texts for Revised Nuffield Biology offered an amended version of the  fourth year  of the five-year course to O-level. The revision was based on the experience of numerous teachers with the original edition. Extra help in the teachers’ guide included: *...

This issue of Catalyst includes the following articles:

Life in the Balance?

Much of the Earth's biodiversity appears to be teetering on the brink of a man-made extinction crisis. Scientists have suggested that, unless urgent...

The resources in this collection show how you can take basic physics and chemistry demonstrations and change them into magic tricks. Each resources comes with teachers notes and a video which shows how to carry out the trick.

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

• Predict when there will be a magnetic field around a wire.   
• Describe factors that change the strength of a magnetic field around a wire.         
• Describe the magnetic...

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 resources allow students to explore natural selection using different coloured baits (spaghetti ‘worms’) that are selected and eaten by birds. Uneaten ‘worms’ are counted after predation and the ‘worm’ population is replenished in proportion to those colours which remain. After several cycles of predation and...

This collection of twelve Scratch cards is designed to provide a quick way to learn how to code using the language Scratch. The front of the card describes to the students what can be done; the back explains how to do it. Each card can be printed and folded to A5 size for use with students. The activities cover how...
