This Core Maths task provides an opportunity for students to create questions based on the idea of someone being awarded a certificate for traveling one million miles with an airline. Students are to decide what information they need to help them answer their questions and then to work out the...

This Science upd8 activity offers an opportunity to test students' understanding of the solar system, and their skills as independent enquirers, problem solvers and effective communicators. Students are part of an earth-bound team set the task of interpreting a range of data relating to the solar system/universe....

Students are introduced to 4 different scales of production that they may come across, one-off, batch, mass and continuous through a video clip showing a wide range of products which they need to categorise into a type of production. Details are given on the characteristics of one-off production, and how it can be...

This online ecology practical, from SAPS, uses random sampling to measure the abundance of various different species on an area of grassland.

Objectives

To give students practice at

• using random sampling to measure the abundance of various different species on an area of...

In this resource from SAPS, students learn about random sampling, diversity and different measures of abundance, before looking at close-up photographs of quadrats and using the field guide to identify them. The resources are intended to help students develop skills and plant identification techniques before going...

This online ecology practical, by SAPS, is designed to give students an opportunity to see how systematic sampling can be used to

• investigate changes in species richness across a footpath
• the distribution of species across a footpath

These online exercises are not intended as a...

This guide is suitable to support a full introductory wearable-technology project using Arduino. It gives an overview of the Arduino system as well as the key terms surrounding ‘making’ and ‘hacking’. After a brief review of basic electrical theory, a closer look at the inputs and outputs of a basic board, and of...

This resource is an introductory lesson to electronic systems. Its content looks at system diagrams (I.e. circuit diagram, flow charts), open loop systems and closed loop systems. Using the key terms input, process, output and feedback, students are given examples of products and asked to describe the system that...

These O.R. Society resources contain seven short films explaining what operational research is, how it is used in a variety of every day situations and what career opportunities the study of operational research affords. The sub collection contains problems to be used to introduce, practice or consolidate a variety...

This activity allows students to  research and present data, using live job and apprenticeship vacancy information found at plotr.co.uk as a stimulus.  Students practise using mathematical tools to present information. The activity will  familiarise pupils with...

A case study from Mathematics Matters which looks at the development of optical fibres and how mathematical models have simplified the process of producing them. Modern society relies heavily on a variety of networks, but we don’t fully understand how they behave. Mathematical network theory lets us create models...

In this video, Cathie Wells from the University of Reading talks about how she is helping aircraft conserve fuel which reduces greenhouse gas emissions by making use of high resolution forecasts of three dimensional wind speeds in the atmosphere. In the associated activity, students are asked to calculate the best...

The purposes of this Revised Nuffield Chemistry option were to review the historical development of a field of chemistry with special reference to its applied and social aspects; to study the life and work of one or more famous scientists working in the field; to create an interest in the original writings of...

The first option of Revised Nuffield Chemistry explored the remarkable properties of water and sought to explain them in terms of the polarity of water molecules and hydrogen bonding. Experiments also investigated the properties of detergents and hardness of water. A further topic was the monitoring of water...

Experimental work in this Revised Nuffield Chemistry option explored the characteristic properties of different types of colloid. The everyday importance of colloids was emphasised and this included a section about cosmetics.
