One of a series from Science & Plants for Schools (SAPS) investigating key topics in plant biology. This practical introduces a simple method to grow radishes, for investigations into the effect of a range of factors on plant growth, including levels of pollutants,...

Investigating serious crimes such as murder, rape and terrorism requires forensic science experts. These people work alongside the police to find the evidence that will bring the culprit to court.

In this Catalyst article, Tony Hargreaves looks at criminal poisoning and shows how forensic science is used to...

A Catalyst article about road traffic accidents (RTAs). After the accident police and other investigators try to establish what went wrong. This may be with a view to prosecuting a motorist, or simply in an effort to improve road safety. An understanding of the physics of motion plays a large part in such...

One of a series of resources from Science & Plants for Schools (SAPS) investigating key topics in plant biology.

This activity allows students to investigate many factors that influence seed germination, including temperature, light, nutrient levels, pollutant effects, tropisms and so on.

It...

The mathematical solution initially explains how to use calculus to find the stationary points of the curve y = x/(16+x²) by rewriting the equation as a product using index form and using the product rule to find the differential. The stationary points are found by equating the differential to zero and...

In this activity, from the LSIS, students discover for themselves the importance of the perpendicular distance in moments. It is presented as a whole class discussion but can easily be adapted for small group work.

The activity uses a magnetic disc that takes about 15 minutes to construct. The activity will...

Vernalisation offers an interesting example of the way that plants have evolved to exploit the predictability of seasonal change and, in this case, to ensure that flowering occurs at an appropriate time. It also gives an example of how environmental factors control and...

Produced by the Learning Skills Improvement Service (LSIS), this case study looks at the theme of harnessing technology. Learners on a BTEC level two diploma in applied science course at Mid Kent College Medway carried out a crime scene investigation as part of their ‘Investigating a crime scene’ unit by Edexcel...

This is one of a series of extended units, from the Association for Science Education and the Design and Technology Association, to provide in-depth coverage of a topic or an area of the curriculum. Through the study of this unit, students can learn about control systems; use a process for analysing systems; and...

One of a series of resources from Science & Plants for Schools (SAPS) investigating key topics in plant biology. In this practical, student investigate how lead inhibits catechol oxidase, an enzyme which is easily extracted from a banana and which is responsible for turning fruit brown. Measuring the intensity...

One of a series of resources from Science & Plants for Schools (SAPS) investigating key topics in plant biology. A simple yet accurate protocol looking at the results of the enzyme catalase. Catalase is a widespread enzyme, protecting the cell from toxic effects of hydrogen peroxide by catalysing its...

One of a series of resources from Science & Plants for Schools (SAPS) investigating key topics in plant biology. A standard protocol which is used to extract phosphatase enzymes from plants, including a method to calculate the rate of reaction. Phosphatases are enzymes widespread in plants easily extracted from...

This resource is designed to meet the specifications for the A-level practical endorsement in England (CPAC). However, given its focus on adaptation and evolution, it will make a valuable resource for those following a variety of different specifications, such as the Advanced Higher Biology Organisms and Evolution...

This resource is from a collection of Nuffield Maths resources exploring dynamics. The demand is roughly equivalent to that in GCE A level. The resources typically include slide shows to introduce the topics, student sheets and teacher notes, as well as other relevant resources.

This resource is a practical...

Understanding the osmotic potential of plant cells is a key part of understanding...
