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...

The ‘development’ section of the Fixpert's resource focuses on creating and testing a prototype for an outcome that meets their fix partner’s needs. Students build critical skills through evaluation and they practice design decision making that balances design ideas against user needs. Activities include a focus on...

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.

Curriculum links include ...

Produced by Science & Plants for Schools (SAPS), the investigations suggested in this resource use duckweeds. These seem to be simple plants - small, green, and with no flowers. However, this simplicity makes them ideal experimental organisms for investigations into...

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

...

From the Biotechnology and Biological Science Research Council (BBSRC), this investigation has students looking at the conditions needed for seeds to germinate and grow. It is suitable for Key Stage Two students investigating the growth and reproduction of plants and gives teachers suggestions for questions to ask...

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.

These activities allow students to model how environmental scientists compare diversity in different ecosystems by using ordinary playing cards as ‘species’ to generate data to calculate Simpson’s Diversity Index. This can be completed in a single lesson. Some students find the concept of species diversity quite...

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...
