Produced by Science & Plants for Schools (SAPS), this investigation looks at end-product inhibition of the enzyme phosphatase. 

The investigation is designed for students following a Scottish Highers course but it is equally useful for other post-16 courses in biology. 

This investigation involves...

Produced by Science & Plants for Schools (SAPS), this activity enables students to investigate the effects of the plant hormone indole acetic acid (IAA) on root growth in mustard seedlings.

Different concentrations of IAA appear to have differing effects on root growth. These effects may vary from one...

Produced by Science & Plants for Schools (SAPS), this activity enables students to investigate the effects of different concentrations of nitrates, phosphates and potassium on the growth of radish seedlings.

After sowing, the radish seedlings are kept well watered, in a warm temperature under constant...

Produced by Science & Plants for Schools (SAPS), this investigation enables students to investigate the response of leaf discs from sun and shade plants to green light

Leaf discs from a sun plant and a shade plant are put in a sodium hydrogen carbonate solution. The rate of photosynthesis is seen by how...

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...

This Unilever Laboratory Experiment, published in 1970, describes the analysis of fluorescers from soap and soapless detergent powders. The procedure describes how the fluorescers can be extracted from the product, separated by thin layer chromatography techniques, and made visible by exposing the chromatograms to...

Some of the biggest challenges we face stem from how we interact with our environment, and engineering is essential to finding sustainable solutions. From renewable power to recycling, to making our homes more energy efficient, and tackling how we feed a growing population, engineering is a vital field.

Some of the biggest challenges we face stem from how we interact with our environment, and engineering is at the heart of finding sustainable solutions. Working with water is particularly important when thinking about the environment because water sustains all life and is essential to the survival of the planet....

Cre8ate maths provides these activities which investigate the tessellation of regular polygons and its application in construction. Initially students identify which regular polygons tessellate, providing the opportunity to discuss the interior angles of polygons and...

This Nuffield Working with Science unit aimed to excite interest in natural and built environment while encouraging students to take an interest in environmental issues.

Guidance for teachers and technicians appears...

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...
