Eleven-year-old Dominic Holden of Newlands Intermediate College in Wellington has taken dwelling six prizes, a brand new iPad and greater than $1500 on the Niva Wellington Science and Expertise Honest.
For 11-year-old Dominic Holden, the very best a part of any mission is the experiment.
A seventh-year scholar at Wellington’s Newlands Intermediate College has obtained six prizes, a brand new iPad, and greater than $1500 for her entry, “A New Type of Block,” on the Niva Wellington Science and Expertise Honest.
And success with this award runs within the household – 31 years earlier, his father gained the identical award on the similar age.
Dominic’s objective was to cut back carbon emissions from the greenhouse gas-heavy development trade. In accordance with the constructing analysis group Branz, development and demolition waste can signify as much as 50% of all waste in New Zealand, with 20% going to landfills and 80% going to cleanfill websites.

Dominic made a collection of recent constructing bricks incorporating the standard waste supplies: glass, polystyrene, sawdust and rubber, with a pure cement brick as a management.
Every brick was a combination of two components builders, two components chosen waste materials, and one half cement.
They put the bricks via a number of exams for energy, thermal conductivity, porosity and sturdiness. “Bricks should not take in greater than 20% of their very own dry weight,” he stated—any extra, and so they’ll develop mould.
He designed a lever that might apply a measurable quantity of stress. The strongest brick was product of pure cement, which may stand up to 1000 kg, adopted by 460 kg of glass within the brick.
For the freeze take a look at, he soaked half a brick in water for 48 hours, then positioned it within the freezer for one more 48 hours to see if freezing the water would trigger the brick to crack. This time the very best outcome was ready by polystyrene.
Total, bricks containing glass and polystyrene have been the very best – sawdust was the worst.
His father, Chris, gained the identical award in 1991 for a mission finding out lichens rising on a strolling monitor in North Wellington to cut back their sensitivity to air pollution.
Dominic stated he needed to make use of his coding information to pursue a profession in pc science. He was nonetheless deciding what to do with the prize cash.
“If I had recommendation for anybody else excited by science, I might say ‘go for it’,” he stated. “Nothing is stopping you; simply hold targeted, work arduous, and it’ll repay in the long run.”
Sylvia Nicol, chairman of the honest’s organizing committee and Niva atmospheric scientist, stated the younger contributors displayed unimaginable ingenuity and creativity.
“The potential for entries this 12 months was terribly excessive,” she stated. “These festivals encourage college students to suppose and behave like scientists and engineers, serving to them to discover topics which are necessary to them in a artistic manner.”
