This resource includes data on blackbirds caught and ringed in a single garden in the UK across a period of several years. It includes interesting background information on the migratory habits of these birds, and the characteristics of European and ‘British’ resident birds.

The data, which is a rich source...

This Catalyst article explains how chemists build molecular 'traps' to mimic the surface of a cell. To scientists, sugar is much more than a food; sugar molecules can also form polymers which act as ‘molecular bar codes’ to help cells recognise each other. The article describes how chemists made a synthetic...

Purpose: Observing changes over time can result in the collection of a lot of data. One method of keeping a central record for the class is to set up a blog or a wiki for the duration of the investigation where photographs, measurements, results tables and graphs can be collated. Using a digital record rather than...

A Catalyst article about fainting and how it can be the result of a sudden drop in blood pressure, which is often part of a shock reaction. Maintaining blood pressure is an important part of keeping the human body in balance. This article examines hypertension, living with high blood pressure, and the relationship...

Bloomsbury Discovery books are part of a new series covering a range of high-interest topics... from space and the solar system to rainforests. Learning has never been...

This resource, from Siemens UK, looks at the use of wind farms to provide sustainable energy for a range of communities in a variety of settings. The selection of a New Zealand context is significant as Maori communities see themselves as being responsible for effective stewardship of the land for future...

A National STEM Learning Centre and Network Engineering Case Studies resource investigating the evolution of the Blu-Ray DVD player, starting with the invention of the laser in 1958. This is a science enquiry story of how these devices have evolved from the invention of the laser in 1958 to the high-tech blue laser...

In this lesson children investigate the insulating properties of blubber and consider how the adaptations of Arctic organisms help develop these.

Children imagine what it would be like to live in a really cold place like the Arctic. How would they keep themselves warm?

The focus of this activity is on the principle of hydrodynamics through testing boat hull designs in a test tank.

This activity gives students the opportunity to explore and develop their critical thinking and decision making skills through a practical approach....

In this activity, from the Institution of Engineering and technology (IET), students investigate a use of electronic systems to improve health care.

They study a case where a Body Centric Antenna (BCA) increases the...

Body centric communications is any communication on, within or around the body using wireless technology. In this film, engineers give examples of the applications of this technology, including wireless devices which monitor blood glucose and communicate directly with a device which can administer insulin. This...

Body centric communications have abundant applications in personal healthcare, smart homes, personal entertainment, identification systems, space exploration and military. This scheme of work, from the Institution of Engineering and Technology (IET), investigates the driving technology behind body centric...

A Catalyst article about the use of tiny electronic sensors to monitor the movement of people. As electronic devices get smaller and more powerful, they are finding new uses in monitoring human activity. This article describes a project to develop sensors with uses in medicine, sport and electronic gaming.
