Students recreate the reaction of a volcano using baking soda (sodium bicarbonate) and vinegar (dilute acetic acid).

This activity includes a game-based approach to measuring reaction speed. Fast reflexes are vital to astronauts who may need to deal with rapidly escalating incidents and high-speed projectiles.

The effect of distraction on reaction speed is investigated – students collect multiple readings and take averages...

In this resource from the IET, pupils learn about chemical reactions and osmosis, whilst designing, making and decorating salt dough Christmas decorations. The resource includes full lesson guidance and a maze puzzle as an extension activity.

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 is an interview with Olivia - a fragrance finder.

A Catalyst article about food additives. Some additives are natural and some are manufactured by the chemical industry. Some, like vitamin C, can come from either natural or artificial sources. As with every other component of food all additives are chemicals. Even organic food can contain a certain number 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...

This activity from a series of resources looking at the future of flight from the IET, explores making hydrogen from water, which is the basis of hydrogen fuel cell technology. Hydrogen is an alternative to petrol and diesel fuels for combustion engines and the only byproduct of using it is water, so it does not...

This activity, from the Institution of Engineering and Technology (IET), focuses on understanding that changing the composition of a material will affect its properties and characteristics.

It is intended that...

In this activity, students carry out research into the development and application of hydrogen fuel cells. Students are asked to produce a presentation or podcast which includes:

*An explanation of what hydrogen fuel...

In this lesson, students explore the functional properties of food. They learn about the Maillard reaction, dextrinisation, caramelisation, gelatinisation and other characteristics of carbohydrates as well as the properties of protein and fats and how these contribute to the appearance, taste and texture of food....

In this lesson, pupils explore the functional properties of food. They learn about the Maillard reaction, dextrinisation, caramelisation, gelatinisation and other characteristics of carbohydrates as well as the properties of protein and fats and how these contribute to the appearance, taste and texture of food.

This Nuffield Advanced Chemistry Special Study enabled students to see something of the scope of the field of metallurgy, and to appreciate its dependence upon chemical principles. The objectives were to: *consider the relationships between the physical and chemical properties of metallic materials and their uses...

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...

In this lesson students learn about the physical, chemical and bacterial contamination of food at different stages of processing and production. They also learn about positive micro bacterial changes, such as in the production of yoghurt and some cheeses, and the conditions in which micro-organisms survive and...
