Danger: Volcanic Ash

This film, from Twig World, looks at why hundreds of planes were grounded by volcanic ash when a volcano in Iceland erupted in 2010, and how dangerous a volcanic ash cloud can be.

The key points made in the film are:

•In March 2010, the eruption of Eyjafjallajökull in Iceland grounded commercial...

Dangerous Cold

In this activity students consider the questions: How does heat energy move around? How can we model the flow of energy and changes in temperature? What can be done to prevent hypothermia? Why do we need to try so hard to stay at the right temperature? In order to survive and be comfortable in hot or cold...

Dangerous Rain

In this activity students consider the questions: Where does rain water go? How can we model the flow of rainwater in real life? What can be done to prevent flooding? When is rain dangerous? Where do floods come from? How can we reduce the damage that flooding causes? Over the last decade some parts of Europe have...

Dark Energy

This animated clip describes how Einstein used the cosmological constant as a way of keeping his model of the Universe static but that Hubble showed that the Universe was actually expanding. However, evidence now tells us that since the universe is accelerating in its expansion, a new term for what is causing...

Dark Matter

This animated clip explains how Fritz Zwicky noticed that galaxies were missing matter and called this matter, dark matter. Zwicky realised that looking at gravitational lensing of light from distance galaxies would allow scientists to calculate how much dark matter there is but there still remains the problem of...

Dark side of blue light

There is scientific evidence that the blue light emitted from mobile devices and computer screens disrupts sleep by delaying the body clock.

In this activity students carry out an investigation using filters to find...

Darkness dwellers

This resource requires children to imagine the world without any light. Drawing from nature for ideas and inspiration, they design ‘stick people’ with special features and powers to live in a world of darkness. The lesson is best done in a woodland or...
