Primary Science Show

On Tuesday 18 August, the Science Ambassadors namely: Jordan Fish; Lizzie Reedman; Amelia Coey; Ethan Redpath and Connor Ferguson organised a number of experiments to demonstrate to the Primary School students. Assisting the Science ambassadors were the two academic leader Charlie Bidgood and Lize Kasselman.

Lize performed a number of chemical reactions that changed colour from colourless to yellow and colourless to red using indicators.

Ethan demonstrated the ‘chilling effect’ of dry ice as it changed the colour of the indicator containing water from yellow to red. He also demonstrated the erupting soapy bubbling effect of washing-up liquid in warm water containing dry ice.

Lizzie and Amelia 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.

Charlie demonstrated a chemical reaction to produce hydrogen gas. After collecting the hydrogen in a balloon he attached the balloon to a metre ruler and exploded it using a candle. The explosion really made the Primary students excited and slightly deaf.

Connor and Jordan demonstrated the hair raising effects of the Van der Graaf generator. A number of brave victims (I mean volunteers) wilfully risked being zapped by this static producing device. It definitely ended up a hair raising experience for these volunteers.

I would like to thank all the Year 11 Science Ambassadors and the Year 9 Academic Leaders involved for their excellent demonstrations and for their time and enthusiasm.

Finally, I would also like to thank Mrs Ritson for her assistance with setting up the demonstrations.

Fenton Doolan, Head of Science
