Plant gums are often used in the food industry as thickening and stabilising agents. Gums are water soluble polysaccharides, such as starch and cellulose. In this activity, students investigate what happens to the texture when different polysaccharides are mixed.

When solutions of some polysaccharides are...

This resource uses the context of football to introduce a heart rate investigation. Students take part in suggested exercises and measure their heart rate and recovery time.  They need to plot of graph of their heart rate for different activities, and are encouraged to decide the axis and scale of the graph for...

These resources allow students to explore natural selection using different coloured baits (spaghetti ‘worms’) that are selected and eaten by birds. Uneaten ‘worms’ are counted after predation and the ‘worm’ population is replenished in proportion to those colours which remain. After several cycles of predation and...

These resources were developed by the Gatsby Science Enhancement Programme and the Centre for Science Education at Sheffield Hallam University in order to demonstrate new ways that ICT can be used to enhance practical work in science. Research scientists use computer technology in both the collection and the...

This biology extension module from the Salters’ Science course reviews the history of biotechnology to introduce the use of microbes in large-scale industrial biochemistry. Student ideas about positive uses of microbes are reviewed. Students monitor the growth of single...

Produced by Science & Plants for Schools (SAPS), these materials look at the work of the plant biologist, Julian Ma. Through seeing how natural and genetically-modified plants can produce medicines, students gain a greater understanding of the career opportunities...

Produced by Science & Plants for Schools (SAPS), these materials look at the work of product manager, James Seymour. Through investigating organic food crops and horticulture, students gain a greater understanding of the career opportunities available in plant...

Produced by Science & Plants for Schools (SAPS), these materials look at the work of plant research scientist, Beverley Glover. Through activities based around plant adaptations, students gain a greater understanding of the career opportunities available in plant...

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

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...

A Year Ten module from the Salters’ double award science course. Practical tests using “urine” samples illustrate chemical diagnostic testing for illness. Different types of illness are classified, also different types of micro-organisms and the body’s defences against them. Experiments show how bacteria grow and...

In this lesson from the Science and Technology Council (STFC), students use an experiment to see if carbon dioxide does cause global warming. The lesson starts with a presentation which raises questions to be answered by the experiment. Students are asked to evaluate the method and results before planning and...

Two lessons from the Science and Technology Facilities Council (STFC)'s Seeing Science in which students look at how some plants absorb heavy metals. The lessons include an experiment to measure the amount of copper absorbed by lettuce and radish plants. In another activity, students use evidence cards and a map to...

This mystery can be used to introduce osmosis and diffusion. 

Two beakers are displayed at the front of the room. Both look identical in that they both contain a plastic zip--lock bag with a starch solution inside. The zip-lock bags are both sitting in a clear solution. What the students don’t know is that...

Six practicals produced by the Institute of Physics (IOP) that help students to understand the electromagnetic spectrum and about materials used in making spectacles.

In addition to the guidance included for specific activities, please refer to the generic health and safety information before commencing any...
