Scenes of Hawaii's Kilauea volcano spitting out lava as featured on the news earlier this year spurred a Year 10 Iona College student to come up with a concept that took out the top prize at the Hawke's Bay Science and Technology Fair.
Olivia Webster's 'Ash and the Beanstalk' investigated growing plants in ash to determine whether or not the ash affected growth.
"I wondered what would happen once all the nearby trees and plants had burnt down and whether they would grow back from seeds in the ash," she explained.
"I found out that once the percentage of dirt to soil ratio was over 50 per cent, the ash held too much moisture and made the bean seeds go rotten, They didn't start to germinate. But they did in the 25 per cent ash to dirt ratio, as there was a better balance between the two."
Olivia spent time during their after-school science class to research more deeply and planted, watered and measured the plants every day.
