Mr Keyes with Yr 11 and 14 Physics students

He also brought along two of his telescopes, one of which was specially designed to look at the Sun (something you should never do with the naked eye or a normal telescope).  He also brought along some samples of meteorites that have made it all the way through the Earth’s atmosphere to the surface from outer space.  The presentation stimulated a lot of interest as was evident from the many questions asked by students during and after the presentation.  

Our thanks go to Mr. Keyes, who took time out from touring with AC/DC, to share his knowledge and passion for Astronomy with us.

In this experiment Matthew demonstrates an example of an endothermic reaction.  The reaction cools down sufficiently to freeze a small amount of water which is between a block of wood and the beaker that chemicals are reacting in.
