One of a series of resources from Science & Plants for Schools (SAPS) investigating key topics in plant biology. In this practical, student investigate how lead inhibits catechol oxidase, an enzyme which is easily extracted from a banana and which is responsible for turning fruit brown. Measuring the intensity...

One of a series of resources from Science & Plants for Schools (SAPS) investigating key topics in plant biology. A simple yet accurate protocol looking at the results of the enzyme catalase. Catalase is a widespread enzyme, protecting the cell from toxic effects of hydrogen peroxide by catalysing its...

One of a series of resources from Science & Plants for Schools (SAPS) investigating key topics in plant biology. A standard protocol which is used to extract phosphatase enzymes from plants, including a method to calculate the rate of reaction. Phosphatases are enzymes widespread in plants easily extracted from...

Understanding the osmotic potential of plant cells is a key part of understanding...

From Science & Plants for Schools (SAPS), this practical activity was developed for Scottish Highers specifications, but the protocol can equally well be used for other specifications. 

Students look at potato cyst nematodes, a serious pest of food crops. This is a good example of parasitism to study as...

This protocol allows students to investigate the effects of the hormone auxin (Indole Acetic Acid or IAA) as a plant growth regulator. The investigations give opportunities to look at auxiliary bud development, root development, and leaf abscission in Coleus. The method is suitable for independent investigations by...

The resource pack, written by Peter Freeland, contains 50 practical investigations designed to introduce aspects of applied biology and biotechnology. The topics are wide ranging, including enzymes, food manufacture and fermentation technology, together with health education, plant propagation, pest control, waste...

This brief resource provides five ideas for investigating the effects of eutrophication on aquatic plant life. Each activity is based on setting up a range of solutions with increasing amounts of minerals and following the growth of aquatic plants. The resource offers suggestions of how the mineral content could be...

The SAPS ELISA kit for Botrytis has been developed as a low cost kit to bring practical immunology into the classroom. The monoclonal antibody in the kit detects Botrytis, a fungal pathogen. Botrytis infects plant material (such as strawberries, raspberries, tomatoes and flowers) and is of considerable importance...

In this activity from Science & Plants for Schools (SAPS), students investigate what causes a Venus’ Fly Trap to shut. These experiments are related to a series of investigations that Darwin carried out as part of his work on evolution and adaptation and background...

This Unilever Laboratory Experiment, published in 1966, describes the use of steam distillation to separate oil from crushed cloves. The method for extracting the eugenol from the oil used carbon tetrachloride (tetrachloromethane) and so would need to be modified before this could now be done in schools and...

In this resource from the IET, pupils learn about density and materials, whilst creating their own density columns and making jingle bells dance. Using Christmas as the context for this STEM experiment, the activity provides detailed guidance and a maze puzzle extension activity.

This Salters’ Chemistry Course unit from the University of York Science Education Group covered:
* The use of soaps and soapless detergents.
* Emulsions and the action of emulsifiers.
* The hardness of water.
* The manufacture and use of cosmetics,...
