This video demonstrates how applying pressure to ice melts it, yet on removal of the pressure the ice re-freezes.  This is called regelation.

This publication, produced by the Association for Science Education (ASE) in 1996, is intended to help teachers in assessing children's progress in science investigations at Key Stage Two. It considers evidence collected from teachers and includes examples of work produced by children in Year Four and Year Six....

Aimed at primary level, this pack investigates the science in everyday life. They investigate a range of topics including: irreversible reactions involved in cooking, the density of liquids, microorganisms, properties of materials and electricity. Designed to demonstrate key ideas and concepts and to spark an...

This topic, from the Association for Science Education, allows classes across the world to exchange information about waste management. Students discuss the ways in which their community deals with waste and what can be done to cope with the problems caused by waste.

This topic introduces students to the...

Donald Palmer's job involves studying, and teaching others how, the human body protects itself from infections and malfunctions, including cancer. He is especially interested in the way the immune system changes with age, and examines the surfaces of human cells using chemicals and instruments.

As a child...

A Catalyst article about Dorothy Hodgkin who was a pioneering scientist, a peace activist, a mother of three and a Nobel Prize winner. The article looks at her life and work in science. She did valuable work as an X-ray crystallographer and in finding the structure of biologically important molecules such as...

In this resource children are challenged to create a Jurassic forest in the classroom. They explore the kinds of animals and plants that would have lived there and find similarities and differences to plants living today. The activities link to aspects of learning about living things in their environment and the...

This Science upd8 activity draws on clinical trials. Eight young volunteers had been in clinical trials before, but this time things went horribly wrong. Six of the eight were left fighting for their lives. In this discussion activity students consider whether new treatments should be ever tested on human...

These three activities, from Centre of the Cell, demonstrate how double blind trials are run, explaining what a placebo is and how the placebo effect works, how bias is removed as far as possible and how participants and trial medicines are randomised. Through these activities, students investigate the placebo...

The Double Crossed project was developed by the Centre for Science Education and supported by the Astra Zeneca Teaching Trust as a collaboration between science and history teachers to produce cross-curricular resources.

The project aim was to make science learning more accessible, effective and enjoyable by...

Developed by the Centre for Science Education and supported by the Astra Zeneca Teaching Trust, the Double and Triple Crossed projects aimed to bring science and history together to increase engagement in science through topic based, contextualised learning.

The project enabled thirteen science and history...

Like the Deflection tube investigation this allows A-level students to measure the specific charge for an electron. It provides a step-by-step guide, along with the calculations that are required to find this measurement.

A series of images representing double helix images.

• DNA double helix and sequencing output: molecular model of a DNA double helix showing the individual atoms (apart from hydrogen) as coloured balls. Carbon atoms are in white, oxygen in red, phosporus in purple and nitrogen in blue....

Produced by Science & Plants for Schools (SAPS), the investigations suggested in this resource use duckweeds. These seem to be simple plants - small, green, and with no flowers. However, this simplicity makes them ideal experimental organisms for investigations into...
