Aimed at students aged 5-14 years, this pack contains a range of different activities based on the theme of waste. The activities cover a mixture of topics including: the environment and pollution, recycling, separating materials, waste degradation, and digestion. Designed for use in class or within a science week...

This resource, from ESA, is intended to familiarise students between the ages of 11 and 14 with the subject of satellite imagery. Satellite images are of increasing importance in a great many domains and are dramatically changing the way the world and physical phenomena are perceived.

Their use and...

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.

These diagnostic questions and response activities (contained in the zip file) support students in being able to:

• Identify more than one location of evaporation
• Explain the formation of clouds.
• Describe where groundwater is found.
• Predict the permeability of a rock based on...

Produced by the Earth Science Teachers' Association, these resources look at water supplies. Students consider the permeability of rocks when seeing how to supply water in an arid environment.

They look at waste...

In this activity students consider the questions:

• What are the main sources that cause severe water shortage in Europe?
• How different harmful elements (e.g. fertilizers, gasoline, sulphuric acid) pollute freshwater?
• What methods / strategies can be used to save water?
• What methods...

A problem-solving lesson where students look into the ways to conserve water using sustainable buildings and water recycling, the use of grey water, maintaining infrastructure and desalination. This lesson provides an opportunity to make some links to the multitude of careers available in this area.

Learning...

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 investigates the pollution of a local pond or lake by looking at the species which are able to live in it. Some species struggle to survive in polluted waters, while others are more tolerant. The resource may be used when teaching about animals in the local environment, habitats, water and improving...

In this practical activity, students investigate the salinity of three different water samples using a multimeter. Students first calibrate their salination probe and test the salinity of their solutions. Students can be asked to suggest how errors might have appeared...

London sewage treatment was developed to protect Londoners from water borne disease. Now the Thames Tideway tunnel is being built to help the sewage system cope with the rising London population. This lesson will allow students to conduct experimental work to model water treatment and have a chance to consider the...

These technical briefs focus on low cost approaches to accessing clean water and sanitation. This is vital to health and well being and low costs are particularly important to poorer communities in the developing world.

Technical briefs are documents produced by Practical Action which are freely available to...

A selection of images related to water and sanitation.

Practical Action helps local communities in the developing world gain access to services such as water and sanitation, vital for a decent quality of life. Some examples of how they go about doing this and the technologies involved are demonstrated in these videos:

• Dying for a drink - solar powered...
