In this activity from Cre8ate maths students are encouraged to experiment with different kinds of symmetry to create a suitable logo.

There is an exercise in using symmetrical properties to reproduce previously designed logos and this activity is complemented by Creating a logo, which gives students a free...

As the number of cells in a microbial culture increases, turbidity increases. In this experiment students calculate doubling time and growth rate constant using absorbance as the measure of growth. Turbidity is caused by suspended cells in the growth medium scattering light, and may be measured using a colorimeter...

This experiment is a continuation of Determining Doubling Time. Students create a standard curve of absorbance against yeast concentration, and use this to determine the concentration of yeast produced over time.

The standard curve (dry mass, grams per litre) is generated from known concentrations of dried...

This Salters’ Chemistry Course unit from the University of York Science Education Group covered:
* The provision of a safe water supply
* The production of different kinds of drink

In this investigation, students extract iron from a breakfast cereal and consider how our bodies are able to digest iron by looking at its reactions with hydrochloric acid.

A Year Ten module from the Salters double award science course. Models are used to illustrate conservation of current in a series circuit leading to studies of voltage, current and resistance and the resistance law. Devices which have different resistance in response to...

From Solar Spark, this practical activity explores the reactions at electrodes in an electrical circuit. A solar cell contains two electrodes. Different reactions happen at each electrode so that electrons can move around the circuit to give an electric current. In this experiment students use filter paper soaked...

A Year Ten module from the Salters’ double award science course. The module begins by looking at the large variety of labour-saving devices now available and their impact on life-styles. Students work with a range of common electrical devices to investigate the relative...

This multimedia package was developed by the Gatsby Science Enhancement Programme to provide teachers with clear and consistent ways of talking about energy. Energy is a particularly difficult concept to explain. These resources aim to cut through the confusion that often surrounds the energy concept, and examines...

This booklet is part of the ‘Innovations in Practical Work’ series published by the Gatsby Science Enhancement Programme (SEP). An important part of understanding energy is getting to know the different ways it can be stored and transferred. Finding ways to do this with...

A Year 11 module from the Salters’ Key Stage Four double award science course. This module deals with the generation, transmission and supply of electric power.

Understanding of the inductive effect is developed...

This Salters’ Chemistry Course unit from the University of York Science Education Group covered:
* Sources and uses of energy.
* Conservation of energy.
* Alternative and renewable energy sources.
* Solar energy as a fundamental source of biomass...

This chemistry extension module from the Salters’ Science course deals with the energy changes which accompany chemical reactions. Photosynthesis is considered as the fundamental source of energy to sustain life process, and respiration as the mechanism for coupling the energy to body processes. ‘Calorific values’...
