Year 5 Science Symposium
National Science Week is Australia’s largest annual celebration of Science, Technology, Engineering, and Mathematics (STEM).
On 17 August, the students of Gioia House donned their lab coats and participated in a Science Symposium to celebrate National Science Week. They were provided with the opportunity to rotate through a variety of experiments and demonstrations that sparked their curiosity and encouraged them to be fascinated by the world in which we live.

The students were challenged to beat gravity, use chemical reactions to make raisins dance and blow up balloons, test the density of liquids through the construction of lava lamps and rainbows, test aerodynamics through paper aircraft construction, and test engineering principles while constructing bridges.
Group 4 – Isabella Xiao, Maree Sialepis, Madeleine Loncar – placed first and Group 1 –Sophia Witting, Keira Van, Victoria Kim –placed second.
The students said, ‘We really enjoyed the day, it was a great opportunity to work together and apply the titration techniques we encounter in our curriculum to a new and exciting challenge. We encourage next year’s students to get involved as well! We have immensely enjoyed participating in the challenge and improved our titration skills.’
THE STUDENTS LOVED THEIR INVESTIGATIONS:
In Mr Dunphy’s Science class we investigated gravity. We learnt about our base and centre of gravity, and how they affect what we are able to physically do. We participated in a series of demonstrations where we had to challenge gravity. One task required us to jump forward whilst holding our toes. This proved impossible because to jump forward, your centre of gravity must move ahead of your base. Holding onto your toes prevents you from making the balance shift. We discovered how the artful use of gravity can throw you totally off balance.

I enjoyed discovering that salt dissolved in water can change the mass and density of water. My group were able to create a segmented water rainbow in the test tube.
