Kavanagh College pupil Ollie Meikle, who earned this year’s "Best in Fair" award at the Aurora Energy Otago Science and Technology Fair prize-giving yesterday, has the answer.
It all started when the 17-year-old was at the Orokonui Ecosanctuary wondering why the leaves of the horopito, also called the pepper tree, have their distinctive taste.
"I discovered that it was because of a red pigment and went from there."
The year 13 pupil initially thought the red pigment was there to prevent predators from munching on the leaves.
But his research project, which drew on his knowledge of botany and chemistry, found the pigment is instead a defence mechanism.
"After they’ve been eaten they produce the red pigment to protect themselves while they heal.
"Which is why ... [the project has] the title: ‘Ambulance at the Bottom of the Cliff’."
Convener Dr Steven Sexton said he was thrilled with the quality of this year’s entries to the science and technology fair.
"It was really hard judging between the top three and four."Other results: Niwa’s Best Water and/or Atmospheric Award: Ivy Barrons’ "Air Pollution" Portobello School, year 8.
