This Cre8ate maths activity draws on measuring stretchiness which involves the collection of real data, calculating percentages and experimental design. This resource models one way in which engineers use their knowledge of mathematics to investigate the properties of materials. Here students investigate the...

This booklet is part of the ‘Innovations in Practical Work’ series published by the Gatsby Science Enhancement Programme (SEP). In recent years, the development of new magnetic materials has shown extraordinary advances. The remarkable strength of the latest generation...

In this activity, students investigate the three main types of memory - sensory, short-term and long-term. An explanation is given for each one and linked to a memory experiment. Students are also given five memory tasks to complete which include looking at factors that affect peoples' memories and ways in which to...

A Year Ten module from the Salters’ double award science course. The first section of the module introduces the formation, composition and structure of the atmosphere. The Sun is our main source of energy. Students consider why sunlight is more intense near the equator...

This chemistry extension module for the Salters’ Science course deals with the nutrients provided by food and their contribution to the diet. It also deals with methods of food processing and preservation. The module begins with a survey of the chemical composition and...

A Year 11 module from the Salters’ Key Stage Four double award science course. This module begins with revision of prior knowledge about stars, planets, moons and other bodies found in space. Students then consider gravity as the force which controls movement of bodies...

In this biology extension module of the Salters’ Science course, an exhibition of foods is used to introduce examples of using microbes in food processing. Students make sauerkraut and learn about the establishment of microbial populations in new habitats. Positive uses...

RAL Space is the UK’s national space laboratory where our thermal engineers and technicians help design and build spacecraft. They make sure that the components will work correctly and are protected in the extreme temperatures of space by using a special type of insulation. In this activity and presentation, pupils...

A Year Ten module from the Salters’ double award science course. The story-line for this unit is the whole world market for manufactured chemicals and the need to transport them safely to where they are needed. This shows the importance of systems which convey concise,...

This Salters’ Chemistry Course unit from the University of York Science Education Group covered:
* The range of properties of chemicals.
* The use of symbols, formulas and balanced equations.
* The commercial importance of chemicals.
* Factors...

In this Catalyst article an experiment is described in which the formation of clouds can be replicated. The experiment requires nothing more than a plastic bottle, warm water, matches and a small thermometer.

This article...

A Catalyst article describing how to make a spectrometer to analyse light by using a CD to split the light and some other household items for the rest of the equipment.

This article is from Catalyst: Secondary Science Review 2011, Volume 21, Issue 4.

Produced by Solar Spark, this simple activity helps to answer the simple, yet complex question: Why is the sky blue and the sunset red? It's all to do with light scattering and the Tyndall Effect and can be easily demonstrated using a suspension of milk in water.

Milk particles suspended in the water cause...

Whey is a waste product from the cheese industry. In this experiment students upgrade whey, by converting the lactose into glucose and galactose, or by growing the microorganism K.lactis on agar containing whey.
