Dr Mary Webberley from the Marshall Centre for Infectious Diseases celebrated National Science Week with year 5&6 students from North Cottesloe Primary School. The students learned about acids and bases and the pH scale through hands on activities with a pH indicator made from cabbage water. The students tested household substances with the indicator and made conclusions based on their recorded observations of colour changes. During the National Science Week event, the students also learned about scientific endeavour through hearing about Professor Barry Marshall and Prof Robin Warren’s work leading to the discovery of the bacterium Helicobacter pylori. Through hearing about the rapid urease test, a diagnostic test for Helicobacter pylori developed by Prof Marshall, they also learnt about how inventors translate basic science into useful products. They were able to make their own ‘model’ tests with an agar plate, urea, pH indicator, and urease containing soya beans to mimic the bacteria.
