The experiment formed part of a professional learning day, encouraging high school teachers to better understand how chemistry could be taught in a more interesting and easier manner.

Head science teacher of Temora High School Moira Burns said while there has been an increase in senior students the learning day aimed to ensure teachers were confident in helping students develop the skills to make informed scientific judgements as they grew up.

"It is not only about those students in the minority who will take on science," Ms Burns said. She said a knowledge of chemistry would benefit students as topics such as climate change and carbon tax, IVF reproduction technology and genetically modified crops became more frequent.
