Produced by the Institute of Physics, this learning episode helps students to move beyond the idea that nuclear changes are represented solely by alpha, beta and gamma decay. Students learn that other events occur when a nucleus absorbs a particle and becomes unstable.

A Catalyst article about chemical reactions that occur in a blast furnace during the steelmaking process. This short article features a diagram of a blast furnace showing the active ingredients used to produce iron from ore.

This article is from Catalyst: GCSE Science Review 2006, Volume 16, Issue 3.

This resource, from the European Space Agency, contains exercises in physics and chemistry based on real space data, designed for secondary schools. The exercises and data were developed and checked by ESA space scientists and engineers. They are most appropriate for students at Post 16 level. There are a total of...

This Catalyst article looks at Biochemistry, the study of chemical reactions in living things, exploring how it differs from other biological subjects and how examples can be found in everyday life.

This article is from Catalyst: Secondary Science Review 2011, Volume 22, Issue 2.

The Nuffield Science in Practice advanced textbook was organised unit-by-unit and carefully structured to help students find the information they needed. The book featured vocational case studies that were specially researched by a team of science writers and teachers...

Using the context of archaeological science, students investigate the food and diet of the people of Stonehenge and the nearby settlement of Durrington Walls, 4500 years ago. There are opportunities for students to test rates of reactions between milk and acids or enzymes used in cheese making, to consider the...

This Catalyst article investigates how honeycomb (cinder toffee) is made using a thermal decomposition reaction to produce the gas bubbles. Sodium hydrogen carbonate (also known as sodium bicarbonate or bicarbonate of soda) has the chemical formula NaHCO3. When it is heated above about 80°C it begins to break down...

These downloadable videos and animations are part of the multimedia package Stuff and Substance, and are intended to be used to establish the concept of a substance. The individual video and animation files are provided separately here to allow flexibility in their use...

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 of chemical change by showing that in some reactions substances decompose...

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...

These Fun-Size materials, from the Association for Science Education (ASE) are short 5-15 minute activities that enliven lessons. These are part of the SYCD AKA Science collection. They range from short games and word plays through to quick demonstrations. Fun-size is particularly useful when you are working...

A Year Ten module from the Salters’ double award science course. A surveyor’s report on a proposed barn conversion is used to introduce different materials used in construction and issues associated with their use. The lessons which follow then consider each type of...

Catalysis is one of the titles in the series of ASE Lab Books that were published in the early 1970s for the Association for Science Education. Each title brought together the best of the teaching notes and experimental ideas from members of the association that had...

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...
