A collection of resources about stem cells.

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...

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...

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...

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 Catalyst article investigates x-rays. X-rays are used in security scanning and medical diagnosis. Efforts are always being made to reduce the hazard of working with these electromagnetic rays.

The article is from Catalyst: Secondary Science Review 2014, Volume 25, Issue 2.

Survival Rivals are hands-on experiments inspired by Darwin and produced by the Wellcome Trust.

The three resources in the series are:
* I'm a Worm, Get Me Out of Here (exploring natural selection)
* Brine Date (looking at sexual selection)
* The X-Bacteria (investigating antibiotic...

Produced by Science & Plants for Schools (SAPS), this investigation looks at the taste of different fruits and vegetables. Domesticated fruits and vegetables have all been selectively bred so that they contain a particularly attractive taste for humans.

From Science & Plants for Schools (SAPS), this guide explains the rules for using symbols and units which students will meet in their science courses and reminds of the importance of using them, and writing them, correctly.

The guide contains six sections:
1. SI base units
2. Derived units...

A Catalyst article about the problems of badgers transmitting tuberculosis to cattle, but is a cull of badgers a solution to the problem? When cattle are found to be suffering from tuberculosis, a disease which can be passed onto humans, they are routinely slaughtered. It is known that badgers can transmit the...

One of a series of resources from Science & Plants for Schools (SAPS) investigating key topics in plant biology. This reliable and enjoyable practical gives students the opportunity to observe the different pigments involved in photosynthesis using thin layer chromatography (TLC). A low-cost method to get the...

These activities, produced by The Centre for Industry Education Collaboration (CIEC), help students understand about the formulation and design of coating used for tablets taken as medicines. Designed originally as a unit of GNVQ teaching, the materials contain a range...
