Produced by the National Schools Observatory, this PowerPoint workshop and accompanying flash animation explains tidal activity on Earth. The workshop takes the form of a PowerPoint presentation that explains why tides exist, why there are two tides each day and covers related topics such as spring/neap tides and...

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

• Describe the heating effect of current on a conducting wire.
• Predict changes to current through transmission lines using P = I x V. 
• Calculate power dissipated by a wire...

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...

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...

From Practical Action, this challenge asks students to design a simple wind turbine capable of lifting a cup off the floor to bench height. The winning team will be the one producing a machine that lifts the most weight. The resource includes an instruction sheet, wind turbine images, links to videos and...

This resource from the Institute of Physics (IOP), describes how X-rays can be used to image the body. The X-rays video, taken from an IOP Schools and Colleges lecture, describes how Roentgen discovered how to image using X-rays, in his lab. The lecture also describes how barium and iodine can be used to to image...
