Imogen Lang explains her project ‘Bothersome Burnt Biscuits’ to Year 2 students Mia Pierpoint and Ben Wang.The spirit ofNational Science Week was in full flight at Aranda Primary School on Tuesday.

A bevy of student-devised experiments were on show as part of theschool’s science fair exploring a wide range ofdisciplines displaying plenty of ingenuity.

Projects testedhow temperature impacted how bouncy a basketball was, whether body language differswhen people lie, and what conditions create“lunchbox lurgies”.

But Imogen Lang’s project had students salivating.

The 10 year old tested how25g lumpsof cookie dough cooked on seven different surfaces.

She said nearly everyone that walked by herproject clad with more than a dozenchoc-chip examples “wantedto sniff or eat them.”

Her experiment used controls such as putting the trays on the same rack, at the same temperature to see how the variabletray materials affected the cook.

“If you like a chewy cookie stainless steel is the best, followed by glass and for those that like crunchy cookies, hard anodized aluminum is the best,” she said.

“I like mine in the middle so tin plated steel and non-stick carbon steel are the best.”

Science coordinator Bobbi Smith said the students who optedintotheactivitywererequiredtodevelopahypothesis, conduct an investigation, record results and a write aconclusion.

“I’ve been really impressed by the latitude of ideas and also,when we are interviewing the kids,how much knowledge they have gained,” she said.

“Basically my project looked a which shape,circle, square or rectangle, would fall slowest,” she said.

“I figured out the circle parachute had the slowest time of 22.2 seconds.”

The Year 6student dropped each of theprototypes 10 times from her three-meter-high deck at home.

She dropped them from the same spot and did soearly in the morning to minimize breeze.

Studentsquizzedeach otherabout their projects at the fair and voted for their favourite in a people choice award.

A group of nine judges including electronic companyLink Media’s Pat Moloney and Bureau of Meteorology Hydrologist Julian Lerat had the tough job of picking a winner.

Mr Moloney said initiativessuch as this which incorporatedindependent inquiry were essential to toimprovingtheuptake in STEMstudy.

“The kids have been given the opportunity to go whichever way they want which is necessary for science,” he said.

“Science is broader than a textbook. There are no foregone conclusions,you need to let experiments take their course and that’s what is happening here.”

Mr Lerat said speaking with entrants he saw them grasp the broad applications of science andpair their work withtheir own passions.

“Science is not dull,” he said. “It is exciting to throw your ideas into a project and that is what the kids here are learning.”
