This lesson develops the concept of making sense of the standard algorithms for addition, subtraction, multiplication, and division of positive integers. In particular students will work on the following areas:

• Improving conceptual understanding of why and how the algorithms work.
• Developing...

This activity away from the computer is from the Barefoot Computing project. It is intended to provide a theoretical understanding of why and how variables are used in computer programming, using the example of score-keeping in a classroom quiz. Involving several volunteers from the group, the activity uses...

This brief activity uses false-colour images of the Columbia glacier to introduce the idea of using sequences of satellite images to monitor change and focuses on the selection of appropriate data for an investigation.

This resource pack can be used to highlight issues such as global water scarcity, the challenges people face when sourcing water and maintaining a water supply in developing countries and the role of the engineers in solving these problems.

The activities are introduced with a quick quiz and a presentation....

This resource, from Siemens UK, encourages students to appreciate the importance of clean water and the problems that may arise in the absence of it. Students consider soluble and insoluble pollutants and methods of filtration. They then explore contamination by microorganisms, water-borne diseases and the...

This short activity introduces students to the ideas of the footprint and resolution of an image, asking them to choose and use appropriate methods to calculate how these quantities would change as they moved a camera to a series of vantage points above the surface of the Earth

This activity uses a humorous video to raise a serious question: can science tell us what animals are saying, and interpret their emotions? The Bow-lingual dog translator claims to detect animal emotions by analysing bark sounds waves. Students use research evidence to decide whether the device does what it claims...

The Nuffield Foundation provide this resource which can be used to introduce the idea of representing objects using plans and elevations. Students will have the opportunity to identify everyday objects photographed from plan and elevation views, draw 3D sketches of solids from their plan and elevation views, as...

This activity can be used to explore the relationship between shape and hydrodynamics (resistance).

Curriculum links include aerodynamics, resistance, forces, buoyancy and thrust. There are a number of useful links to...

These evidence-based, question and answer style classroom resources can be used to engage students of all ages...

These evidence-based, question and answer style classroom resources can be used to engage students in the climate...

In this activity students take on the role of Earth observation scientists submitting a request for an image they would like for their research. This gives them the opportunity to consider the possibilities of pictures taken from orbit (and the limitations) and to write scientifically for a specific audience. It...

This resource looks at life-cycle analysis and how it is used to work out the environmental impact of different products.

In this lesson, students investigate the claim that using a Nintendo Wii computer game is a good way to keep fit and that people, therefore, should be encouraged to use them. They compare how their resting pulse rate changes when they have been playing a normal games...
