CIBIT theme leader A/Prof Kris Thurecht and his research group held a Science Challenge day at the Springwood Road State School on 19th of September. The event was a joint community engagement and educational initiative between CIBIT and the ARC Centre of Excellence in Convergent Bio-Nano Science & Technology (CBNS). Three primary schools participated in this event: Springwood Road State School, Chatswood Hills State School and Springwood Central State School. Each school was represented by a group of Grade 3 pupils who undertook four different science experiments and competed to be the best school in the science challenges.
The experiments were:
- Surface tension racers: powering boats across the water using soap to disrupt the surface tension and comparing the effect of soap with other liquids.
- Using red cabbage juice as a pH indicator to test the pH levels of common household liquids, introducing the concepts of acids and bases and how they relate to different liquids.
- Creating colourful calcium alginate beads and strings by adding coloured sodium alginate solution to calcium chloride solution.
- Filling balloons with a mixture of yeast, baking soda, sugar and water and investigating which ones sink or float in a bucket of water.
It was a great day of inciting curiosity in school kids to learn about science and witnessing their excitement during the fun experiments. At the end of the day, students were rewarded with a well-deserved ice cream made with liquid nitrogen.
