This Mathematics Matters case study, from the Institute of Mathematics and its Applications, looks at how mathematics modelling can aid investigations into the circulatory system. Blood-related diseases can seriously harm patients’ quality of life and even lead to death. Many of these diseases are caused by...

In this podcast from the Natural Environment Research Council's (NERC) Planet Earth Online collection, Sue Nelson reports from the Royal Botanic Gardens, Kew where she finds out that some plants like the Snake's Head Fritillary have enormous amounts of DNA in their genomes.

These plants struggle in extreme...

This set of inquiry-based teaching resources, created by the Royal Botanic Gardens, Kew, help teachers deliver inspiring lessons about plant science and the environment. These are a sample of a larger collection that are part of Endeavour, an extensive set of curriculum...

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...

From the Chilled Food Association (CFA), these activities are aimed at Key Stage Three students and look at a range of topics that include:
* Common bacteria that cause food spoilage
* Reducing the risks of bacterial contamination
* Food hygiene
* Food and taste
* Developing a new food...

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...

A lesson from the Science and Technology Facilities Council (STFC)'s Seeing Science. Students investigate sulphur dioxide, its sources and its impact on the environment and on life. In the main activity, students create a animated presentation to tell the story of sulphur dioxide. Images and graphics for each act...

Work done in this Nuffield 13 - 16 module followed from the B units called ‘Communities and populations’ and ‘Charged particles’. This S unit provided enough material for eight double periods during a single-certificate science course. The teachers’ guide included four...

In this SATIS Revisited resource students look at the role of the kidney and treatment of kidney failure by dialysis and with transplants, and explore issues around the shortage of donor organs in the UK.

In 2010 the number of individuals requiring kidney transplants in the UK was approximately 8000 people....

A Catalyst article discussing how the human body has to handle all sorts of variations, balancing its inputs and outputs, if it is to work efficiently. The article concentrates on one organ, the kidney, and the way it helps to keep things on an even keel through the functions of homeostasis and excretion. What...

In this Science upd8 activity students look at how Tutankhamun's body was preserved and how scientists used information from CT scans to form 3-D images and reconstruct his face.

These diagnostic questions and response activities (contained in the zip file) support students in being able to:

• Use the idea that organisms can be classified into groups within larger groups.  
• Recognise that organisms can be classified using evidence of their microscopic cell structures in...
