This SATIS Revisited resource is a structured group discussion activity, which looks at the use and abuse of drugs to enhance sporting performance.

The unit provides a rationale for teaching about ethical issues in science for students age 14–16. The aim is to introduce the idea that the discussion of...

Dijkstra's algorithm finds the shortest path for a given problem. Dijkstra's algorithm can be used to find the shortest route between two cities. This algorithm is so powerful that it not only finds the shortest path from a chosen source to a given destination, it also finds all of the shortest paths from the...

In this activity, students develop a marketing strategy and advertising materials for a pure water product. Students mirror the design process within a ‘design consultancy’ and each team makes a pitch for the tender at the end of the project, presenting ideas to the...

This exercise is designed to ensure that students know how to find the expected value, E(X), and the variance, Var(X) for a discrete random variable, and that the probabilities in a probability distribution always add to one. Students are given a selection of numbers and are challenged to establish those...

This resource is designed to meet the specifications for the A-level practical endorsement in England (CPAC). However, it will make a valuable guide to dissection and scientific drawing of a flower for those following a variety of different specifications.

The ability to accurately observe, dissect and...

This challenge enables pupils to model and test filters as a way of making dirty water cleaner. It can also be used to explore ways of making water safe to drink.  Curriculum links include separation techniques and pure substances.

The challenge can provide a focus for National Science and Engineering Week,...

In this activity students consider a population growth problem which leads to a power series. The presentation can be used to introduce the topic and use of spreadsheets would enable students to model and draw graphs of the situation.

Published by the Wellcome Trust, the 'Big Picture' explores issues around biology and medicine.

While providing immense benefits, drugs are not the perfect solution. They only work on a proportion of patients,...

In this activity, pupils will consider some properties of different rocks. They will also learn about classifying, or sorting things into groups to help them identify which rock is which. They can then take a closer look at the meteorites, tektite and ammonite in their sample boxes. There are two versions of the...

These Key Stage Three National Strategy training materials from the Department for Education are designed to run a session with science teachers to help them develop structured three-part lessons by using engaging starters, main and plenary activities.

• Describe the effects of an electric shock on a person.

• Explain why there are no standard mains sockets in a bathroom....

This resource from the Institute of Physics, describes how electrocardiagrams (ECGs) record the activity of the heart through electrodes placed on a patient's skin. The teacher's notes contain an introduction to ECGs and lesson notes for the associated PowerPoint file. A mark scheme for the worksheet is also...

• Identify types of electromagnetic radiation that can be naturally occurring.
• Describe a range of sources of harmful electromagnetic...
