The Science ambassadors namely: Madeleine Roulston; JD Theron; Paige Thompson and Cerys Richardson organised a number of experiments to demonstrate to the Primary School students. Assisting the Science ambassadors were four other Year 11 Science students namely: Bakani Kombanie; Liana Perry; Ellena Jimenez and Robyn Harmse.
Madeleine and Cerys demonstrated the ‘chilling effect’ of liquid Nitrogen on various items such as: strawberries; carrots; sausage; a balloon; and a plastic ball. The students were amazed that a banana could be transformed into a hammer which could be used to hit a nail into a piece of wood.
Liana and Ellena demonstrated the chemical reaction to produce ‘Elephants toothpaste’. The primary students were surprised at the amount of the colourful product that erupted from the measuring cylinder.
Bakani and Paige showed the students a chemical reaction that produced carbon dioxide gas. They collected the gas in a balloon and used it as a model fire-extinguisher to put out a small fire.
Robyn demonstrated a chemical reaction to produce hydrogen gas. After collecting the hydrogen in a balloon she attached the balloon to a metre ruler and exploded it using a candle. The explosion really made the primary students excited.
JD Theron launched a rocket on the oval to celebrate the 50 year anniversary of humans landing on the moon.
Finally, I would like to thank the Year 11 Science Ambassadors and the other Year 11 Science students for organising the Science Show this year. I would also like to thank Mrs Ritson for her assistance with setting up the demonstrations.
Fenton Doolan, Head of Science
