No – the Star Wars cast did not visit us last week – but we DID have a visit from someone who could use the force just as well as Luke Skywalker!

Sam from the CSIRO showed us many fantastic tricks and experiments all about forces and motion. Learning about forces and motion means we are studying physics -and it was great fun and very interesting.

We rode skateboards, lifted heavy objects (and teachers) with no hands, twirled discs, made bridges and even got to sit on a chair of nails.

Did you know that:

• if you go fast on a bike, it’s less likely that the bike will fall over?
• if you squash a balloon across 500 nails it will not burst ….. but if you push just one nail into a balloon it WILL burst? 
• you can’t pull someone on a skateboard with your feet off the ground!
• when you are pulling you are actually pushing! (You push your feet into the ground whilst you are actually pulling  something )
• a small kid can lift a large adult easy as you like if the kid uses a lever (like a see-saw)?
• friction keeps cars on the road as do studs on footy boots?
