A year 11 module from the Salters’ Key Stage Four double award science course. This module deals with radiation and radioactivity, introduced through their uses in medicine, both for diagnosis and treatment. Students simulate non-intrusive tests made by doctors in...

A Year 11 module from the Salters’ Key Stage Four double award science course. The context for this module is the use of scientific ideas to explain human performance. Students discuss what is meant by being ‘fit’. They compare different uses of the word 'work' and are...

A Year 11 module from the Salters’ Key Stage Four double award science course. This module explores the controlled and co-ordinated energy changes which maintain a complex series of interlinked metabolic processes in living tissues.

Several different treatments are used to autolyse yeast cells. The viability of the autolysed yeast is then tested by: plating out on agar; testing for dehydrogenase activity; microscopic examination with methylene blue.

In this activity, students investigate the three main types of memory - sensory, short-term and long-term. An explanation is given for each one and linked to a memory experiment. Students are also given five memory tasks to complete which include looking at factors that affect peoples' memories and ways in which to...

In this biology extension module of the Salters’ Science course, an exhibition of foods is used to introduce examples of using microbes in food processing. Students make sauerkraut and learn about the establishment of microbial populations in new habitats. Positive uses...

In this practical protocol students investigate one way in which bacteria acquire antibiotic resistance through conjugation - horizontal gene transfer from one bacterial strain or species to another.

Plasmid-mediated evolution is fast because whole functional ‘modules’ are lost and gained, rather than the...

Whey is a waste product from the cheese industry. In this experiment students upgrade whey, by converting the lactose into glucose and galactose, or by growing the microorganism K.lactis on agar containing whey.

A Year 11 module from the Salters’ Key Stage Four double award science course. The breakdown of domestic waste is observed. A text exercises describes the processes used in a waste water plant. Natural cycles, including the carbon cycle and the nitrogen cycle are...

This activity looks at water consumption on a local and global scale. Students learn about the main water contaminants and various methods of purification and the role of engineers and their approach to design challenges. The resource aims to inspire an interest in water conservation and to introduce students to...

This student sheet invites students to consider lignification in detail. Students take thin sections from successive internodes of the shoot and calculate the lignification index of each section. These can then be compared with sections from other parts of the plants to consider where lignin is deposited in other...

In this experiment, from Science & Plants for Schools (SAPS), students are required to make observations about wild oat seeds. Using a petri dish, glass jar, filter paper and water, students can recreate the conditions of a greenhouse. They can then observe the changes to direction of the awn (the long hair at...
