Produced by Science & Plants for Schools (SAPS), this activity enables students to investigate the effect of competitive and non-competitive inhibitors on the enzyme beta-galactosidase.

The chemical ONPG (o-nitrophenyl beta-D-galactopyranoside) is degraded by the enzyme beta-galactosidase. The product is...

This topic, from the Association for Science Education, allows classes in schools across the world to explore and exchange information about the many chemical products which people use in their homes. The topic is provided in English and 10 other languages.

Students examine the labelling of chemical products...

The University of York Science Education Group ensured that all the Science in the Environment packs were organised according to broad environmental themes. Within each pack, a number of specific contexts were used to introduce the science content. In addition, each...

Rockets are used to launch satellites, probes and even astronauts into space. A rocket launch is extremely impressive. Thousands of kilograms are burned in just a few minutes in order to provide the force that the rocket needs in order to overcome the gravity of the Earth. Rockets provide an exciting context to...

The first Student Workbook for Nuffield Physical Science began with an extensive introduction to this novel course for students. The Workbook was not designed as a textbook. The content of each section was arranged on the same plan, and each contained four types of...

This activity investigates the potential of hydrogen fuel cells as a means of energy generation and storage. Students make hydrogen gas by electrolysis, supported by practical instruction sheet. Combined with the Burning Fuels 2 resource, students can explore the...

These resources from the European Space Agency climate change initiative education resource pack allow students to learn about the carbon cycle and the key to controlling climate change by managing it and using it to identify how to reduce carbon emissions to the atmosphere. How carbon moves through the carbon...

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

• Describe the effect of different battery voltages on simple circuits.
• Describe the voltage of a battery, measured with a voltmeter, as the strength with which the battery can ‘push...

This resource can be used to demonstrate an understanding of the role of antioxidants in food processing to delay oxidation. A data based activity analyses types of fat in foods and an investigation into the browning of apples under varying conditions allows a quantitative measure of the oxidation reaction. 

This resource from Science & Plants for Schools (SAPS) describes the work of Charles Darwin on carnivorous plants to determine what causes the leaves to curl up when stimulated.

Darwin’s experiments are very easy...

This STEMNET activity case study describes the work of Lee Betts, who works at RAF Cosford, for the STEM Ambassador network and Engineering Education Scheme.

Lee trains other STEM Ambassadors to undertake activities and is also involved in the WISE (Women into Science, Engineering and Construction)...

This issue of Big Picture provides lots of interesting information about flowering plants and their uses. 

The plant hormones animation explores the action of indole-3-acetic acid (IAA) and shows how scientists used experimental evidence to explain the role of auxins in a phototrophic response.

The...
