In this activity children investigate methods of separating mixtures of solids and learn about the problems of ash clouds for aviation.
The Eyjafjallajoekull volcano erupted under a glacier in Iceland. British airspace was closed for 6 days in April 2010, again in early May and continued to affect air travel for up to 2 more years on and off. Many flights were cancelled as the ash cloud - between 20,000 to 35,000 ft high in the atmosphere, threatened the safety of airliners. The ash cloud that came up from the volcano made it unsafe for flying, due to visibility and ash blocking the aeroplane engines.
Children will investigate methods of separating mixtures of solids and learn about the problems of ash clouds for aviation.
- to listen and discuss their knowledge with others and ask questions relevant to the topic
Children will learn:
- to put forward a point of view and alter viewpoint in light of discussion
- to follow simple instructions and compare their prediction with what actually happened
