Yesterday class 5J took part in a live webcast from the I.S.S to hear all about British Astronaut Tim Peake's adventures in space.
Highlights of the session included:
Watching Tim play table tennis with a bubble to demonstrate effects of zero gravity
Following Tim's instructions during an astronaut workout
Finding out what to do when your space suit leaks during a space walk
Observing what happens to a sphere of water when you add a fizzy tablet to it aboard the ISS.
