Hunt for Micrometeorites
In March, it was Science week.
Y8 went searching for space dust during one of their recent lessons. Over a kilogram of grit and dust was collected form the surface of the tennis courts which was then thoroughly washed and sieved. Using a strong neodymium magnet, a very small amount of magnetic material was obtained – about 2g in total.
Approximately 100 tonnes of material from outer space falls to earth each day – a lot of this material when it reaches the surface is less than a millimetre in diameter – some of it is also magnetic. Finding spherical, shiny balls of material was the order of the lesson and is usually a good indicator that it could be a micrometeorite but to be certain the material would have to be analysed further. The class loved the activity and had some success during the lesson.
