Fantastic Pneumatics!

Year 3 have been working hard on their topic of Brutal Beasts and Beastly Battles. This coming week, they are going to be making some moving monsters!

However, before we got busy with the glue and glitter, it was important to start investigating ways to make our monster move.

We looked at a range of toys that use pneumatic pressure to create movement. Then, we investigated how this pressure works by using 2 syringes, some plastic tubing and some coloured water.

We learned that the plastic tubing has to be tight around the end of the syringe, otherwise the water escapes (the same would happen with the air in a pneumatic system). We also learned that the pressure of the water (or air) moving down the tube from one syringe, makes the second syringe move.



We now have lots of ideas about how we can make our monsters move!

I loved playing with the syringes, rubber tube and blue water.
