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...

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...

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...

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...

In this small-scale scoping study, the questions around whether and how teachers of STEM subjects access information about cutting edge research to inform their classroom practice, and how this impacts on the students they teach, was explored.

This study supports STEM Learning’s aims to explore the effective...

This innovative activity uses the context of the distribution of dwarf willow to carry out virtual quadrat and transect sampling techniques.

Initially pupils are asked to discuss the unique characteristics of trees and then debate whether dwarf willow is a tree.

To carry out the field work, pupils can...

This brief resource provides five ideas for investigating the effects of eutrophication on aquatic plant life. Each activity is based on setting up a range of solutions with increasing amounts of minerals and following the growth of aquatic plants. The resource offers suggestions of how the mineral content could be...

This resource, from the Association for the Study of Animal Behaviour (ASAB), allows students to investigate the behaviour of ants, and includes:

• Background information about British ants.
• A step-by-step approach to the collection and maintenance of some British ants with particular reference to...

This activity from the Computer Science for Fun (CS4FN) team at QMUL is an introduction to algorithms suitable for those in upper primary school. A ‘self-working’ magic trick is shown – this is a trick that works every time, as long as the process is followed exactly. No understanding of the trick is needed by the...

A Catalyst article about the astronomer William Herschel who discovered Uranus in 1781. He became the first person since ancient times to identify a new planet. However, he is also known as the ‘accidental’ discoverer of infrared radiation. The article asks is this a fair description and can such discoveries really...

Students check and complete invoices. Students also work with their own data in spreadsheet simulations of invoices.

This resource is part of the Nuffield Maths Level 1 Foundation resource collection.
