We had a thrilling presentation from Dr Adam Baker who works on rockets and satellites and collaborates with the astronaut Tim Peake. Here’s the live launch of an air-powered rocket: rocket launch. And a demonstration of a real miniature rocket engine: rocket engine demo.
Adam told us about the International Space Station (ISS) – a giant science laboratory in space, orbiting the Earth at 25,000 miles an hour. He encouraged us to use the International Space Station tracker (http://www.isstracker.com/) to follow its orbit. There’s also lots of amazing video of the Earth shot from the ISS on the web for anyone interested.
We had an equally exciting presentation from a chemistry teacher at Dulwich College (and Rosendale parent) who explained how atoms are the building blocks of matter and performed some great experiments.

Burning ethanol in a plastic barrel:
Ethanol + oxygen –> carbon dioxide, water [which we saw left in the container] and heat energy [the barrel was warm]

Our thanks go to Rosendale’s excellent science coordinator, Ms Nakibinge, who organised science week.
