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...

Diagram showing the hydrogen bonds that form between the four bases in the DNA double helix. These weak forces between the bases keep the two complementary strands of DNA together and ensure that the correct bases are put in the right place during replication of the DNA molecule. A always pairs with T and C always...

This practical activity outlines how to grow plants hydroponically in the classroom. It aims to give students an understanding of the basic growth needs of plants. It also shows how hydroponics can be utilised to provide food to humans as our population expands.

This technique can be expanded in a number of...

This resource is based around the chemical composition of the human body and the origin of elements in the universe. Students can input a mass in the spreadsheet to see what proportion of their mass is from elements created in the Big Bang, in stars and in supernovae. Graphs are also shown for the relative...

These resources were developed by the Gatsby Science Enhancement Programme and the Centre for Science Education at Sheffield Hallam University in order to demonstrate new ways that ICT can be used to enhance practical work in science. Research scientists use computer technology in both the collection and the...

The IDEAS training materials are for use on continuous professional development courses to support the teaching of ideas and evidence in school science. The materials offer six in-service CPD sessions, which take approximately half a day each. Ideas and approaches for lessons are illustrated using materials...

This file from the IDEAS pack is a set of resource materials to support the teaching of ideas, evidence and argument in school science education. It consists of 15 sample lessons which can be used by teachers wishing to try out some or all of the approaches. The learning goals of the IDEAS lessons are different....

This Catalyst article describes an experiment in which, using a microwave oven, water can be boiled in a cup made of ice, allowing all three states of water to be seen at once. The article explains what equipment needed to carry out the experiment, instructions, and a detailed explanation of why it works.

In this podcast from the Planet Earth Online collection and the Natural Environment Research Council (NERC), Sue Nelson visits the ice cloud chamber in the School of Earth, Atmospheric and Environmental Sciences.

Scientists know that fluffy stratocumulus clouds act like a blanket on the Earth - they stop...

This book invites teachers to explore some of the many scientific results from the CryoSat mission. The book describes key techniques of precise radar and SAR (Synthetic Aperture Radar) altimetry, and reviews state-of-the-art achievements. The book is intended as a living document, and will continue to capture new...

In this practical activity students analyse ice cores extracted from the icy worlds of Enceladus or Europa. This resource provides information about Enceladus and worksheets for both qualitative and quantitative analyses. In the video, Steve Althorpe explains how ice cores containing minerals can be made and then...

This video introduces the process of regelation.  This is when ice melts as pressure is applied to it and then re-freezes when the pressure is removed. An experiment is conducted using two lengths of wire attached to two 1.5kg masses. One wire is made from copper and the other is fishing wire.  Students are asked...
