Technology Challenge

The whole school was involved in a Technology Challenge.  In Room 19, our challenge was to use hydraulics to move an object.  We found that hydraulics works when a force is applied to one end of a closed system - this makes the other end rise up.  We used syringes, tubing and water to make our hydraulics systems.

We worked in small groups to design and make a machine that used hydraulics.  In total, we made rocket launch pads, drawbridges, a dump truck, a tissue puller, a houses lift, a boat lift and marble runs.  At the end of the week, we demonstrated how our inventions worked to Room 9, and they showed us their house designs.  After that, we had time to share our inventions with the other Year 3 classes.

Everyone working hard on their designs.
