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?
