Year 7/8s go BANG!
Samantha Sykes — August 7, 2019
Here you see Chris and Savannah doing the final steps of their science based ako plan. They literally forced chemicals to react. Read below for more info.
After attending a science workshop at the University of Canterbury earlier this year Chris has been learning everything science. He included Savannah and others and soon they had a chemicals ako plan on the go.
In these photos you can see them mixing potassium chlorate and red phosphorus together... very carefully so they do not make a premature bang. Once they are together all that is needed is some sort of force. They thought, what better than a hammer? The two of them took turns at mixing then banging the chemicals together.
When they had the mixture right it let off a very loud bang (sounded like a gun shot), a quick flash and smoke. They enjoyed measuring the bangs on a decibel metre. So much literacy, maths and science all in one!
