This activity involves generating creative design ideas for a building, drawing the final design idea using CAD software, and 3D printing a model of the building. The software used for the CAD activity, ‘Onshape’, is the free and widely used. However, this could easily be substituted for any other 3D CAD...

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...

This Unilever Laboratory Experiment, published in 1973, describes two methods for determining the vitamin C in foods. The leaflet describes the estimation of vitamin C (L-ascorbic acid) in foodstuffs, after extraction with metaphosphoric acid, by titration with a standardized dye, 2,6 dichlorophenolindophenol,...

This Unilever Laboratory Experiment, published in 1970, describes the procedure for a titration with EDTA and Eriochrome Black T to determine the total hardness of water. The details cover the preparation of a standard solution of EDTA as well as the steps of the titration.

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 mystery deals with a laboratory report in which the written results suddenly vanished. The students need to find out how the writing vanished,  how to recover the vanished data, and what the secret of the pen is.

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.

The work suggested in this Nuffield Working with Science unit encourages the students to start thinking about efficiency by presenting them with some problems which are a familiar part of their daily lives. They are asked to investigate problems which have been chosen...

Inspired by the theme of the Victorians, this activity supports the teaching of design and technology in context by looking at the key events that defined the Victorian era, and how they have influenced engineering developments and society today.

In this classroom activity learners will learn about the...

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...

Produced by the Hamilton Trust, this resource aimed at Year Six gives details of six lessons on balanced forces. Children learn about gravity, air resistance, friction and upthrust of liquids. Working scientifically they investigate what happens when an elastic band stretches under force and develop an...

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...
