Produced by Science & Plants for Schools (SAPS), this investigation looks at end-product inhibition of the enzyme phosphatase. 

The investigation is designed for students following a Scottish Highers course but it is equally useful for other post-16 courses in biology. 

This investigation involves...

Produced by Science & Plants for Schools (SAPS), this activity enables students to investigate the effects of the plant hormone indole acetic acid (IAA) on root growth in mustard seedlings.

Different concentrations of IAA appear to have differing effects on root growth. These effects may vary from one...

Produced by Science & Plants for Schools (SAPS), this activity enables students to investigate the effects of different concentrations of nitrates, phosphates and potassium on the growth of radish seedlings.

After sowing, the radish seedlings are kept well watered, in a warm temperature under constant...

This video applies physics to explain how trees can move water up their trunks over 10m, which is the natural limit of sucked water. The ideas of transpiration, osmotic pressure and capillary attraction are considered.  The explanation shows how a negative pressure is be obtained from the intermolecular forces and...

Produced by Science & Plants for Schools (SAPS), this investigation enables students to investigate the response of leaf discs from sun and shade plants to green light

Leaf discs from a sun plant and a shade plant are put in a sodium hydrogen carbonate solution. The rate of photosynthesis is seen by how...

This Catalyst article focuses on the Gorteria, a South African daisy which shows great variation in its flowers. It attracts bee flies to pollinate it. It has been used to test theories of evolution.

Published by the Wellcome Trust, the 'Big Picture' explores issues around biology and medicine. The human brain may be the most complex structure in the universe.

The brain is so powerful that it is attempting to...

Published by the Nuffield Foundation, the Nuffield Advanced Biology Topic Reviews for students were an integral part of the Advanced Biological Science materials, but each could be read on its own. Thus, students could use them for their current work, or to pursue...

The Nuffield Advanced Biology Topic Reviews for students were an integral part of the Advanced Biological Science materials, but each could be read on its own. Thus, students could use them for their current work or to pursue personal interests.

This article discusses how toxic gases gases can be useful in medicine, carbon monoxide is a poisonous gas but it can also help to treat some diseases.

The article is from Catalyst: Secondary Science Review 2015, Volume 25, Issue 4.

This podcast from the Planet Earth Online collection and the Natural Environment Research Council (NERC) looks at how tracking insects can help scientists forecast summer storms and floods, and the role one of Europe's key satellite missions played in the recent floods in Queensland, Australia.

The huge...

A collection of post 16 resources about transcription, translation and gene expression.  These resources are part of the Post 16 genetics and genomics collection.

This booklet contains a range of suggested teaching activities and contexts for teaching about transport in animals at A level. Curriculum links include surface area to volume ratio, circulatory system, heart, blood vessles, cardiac cycle, oxygen dissociation curves, ECG,  and blood flow rates....

A set of ideas and resources for teaching about transpiration and transport in plants at A level, along with some common difficulties which students have on this topic in exams.

Activities include The weirdness of plants, which gives ideas for raising students’ curiosity about how plants live...

This Catalyst article looks at peatlands which usually conjures up images of bleak, boggy hillsides across Northern Europe, Russia and the USA. But peatlands are also found in the tropics. These currently act as a significant store of carbon, yet these valuable ecosystems are under threat; their disappearance could...
