Produced by Science & Plants for Schools (SAPS), this investigation looks at stomatal opening and closing in Commelina communis (Asiatic dayflower). This is achieved by varying the turgor of the guard cells by bathing lower epidermal peels in solutions of different osmotic strengths. Changes in guard cell...

This podcast from the Natural Environment Research Council's (NERC) Planet Earth collection looks at why scientists are working with the National Trust to restore the chalk grasslands around Stonehenge; how scientists are using satellites to study microscopic plants; and the etiquette of dining and bullying in...

Stop the spread is a new STEM challenge for students aged 7 to 16. Highlighting the global issue of infectious disease students design, build and test a model of a hand washing device and produce educational materials for children in Kenya to encourage hand washing. It is accredited for the British Science...

A series of case studies from the Medical Research Council (MRC) which demonstrate the impact of research on society.

There are many factors that influence the healthcare we receive at the doctor's surgery - the story usually begins with discoveries by scientists working in laboratories. Once scientists spot...

From Science & Plants for Schools (SAPS), these practical activities allow students to investigate how woody and herbaceous plants support their shoots, branches, flowers and fruits and shed them at the appropriate time.

A number of investigations are suggested that can be adapted for students over a...

Produced by Nelson Thornes, these materials are samples of their A2 level science resources. They are designed to support the AQA A2 specifications but samples and activities can be applied to the teaching of other courses. Activities cover chemistry, physics and biology and include teacher notes as well as student...

The Young Scientist Investigates topic book on Structures was published in 1984 and gives information, illustrated by full colour drawings and photographs, about structures of living things, buildings, bridges and roads. It is intended for children aged 8-11 to read and then to answer question and carry out some...

These archive materials were produced by the Institute of Biology during the late 1960's until the early 1980's. Over 100 booklets look in detail at different aspects of biology. They describe the trends and developments taking place at the time of writing. Whilst some...

A Catalyst article about the inner surface of lungs, which is coated with surfactant, allowing oxygen to enter the bloodstream. When babies are born very prematurely they can lack this surfactant, and this can make it very difficult for them to breathe. This is called Respiratory Distress Syndrome (RDS). This...

Aimed at Key Stage One, this resource looks at activity levels and how, through practice, the body may perform better. Linked to Pe and the topic of animals including humans, it also aims to develop enquiry skills. Meet the character Fizzy and her dog Dizzy, who want to learn more about the human body and set...

This animation shows the major stages of subcloning. This is the process of breaking up fragments of DNA from BAC clones into smaller more manageable pieces for DNA sequencing. This process was very important during the Human Genome Project. Subcloning involves several standard molecular biology techniques...

Produced by Teachers TV, this video provides an insight into climate change, the change in our world and a change in the way scientists view it. It can be used to explain the topics covered as well as illustrating ideas about how science works. Professor Andrew Watson of the University of East Anglia delves into...

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 sterilise seeds of...

This resource focuses on the sugar content of soft drinks and the constituents of a balanced diet. Students use the data provided from secondary sources to answer a series of questions which explore the effect of drinking soft drinks on students' sugar intake and to compare this to recommended daily amounts. The...

Aimed at Key Stage Two, this resource looks at variation in the size of body parts and how this may affect performance in sport. Providing curriculum links to PE and the topic animals including humans, it also aims to develop enquiry skills. Follow the character Fizzy as she sets the children a series of questions...
