The Waikato's next generation of scientists are showcasing their latest discoveries at this week's NIWA Waikato Science and Technology Fair.
More than 320 projects from students in Years 7-13 have been entered from about 28 schools around the Waikato.
NIWA biologist and science fair co-ordinator Tracey Burton says she is excited about seeing what New Zealand's future scientists have been thinking about today.
"Science and technology fairs are all about getting students to use scientific methods to solve real-life problems. They learn about the value in conducting science experiments that have been properly researched, designed and analysed.''
Innovation is always a key component at the annual NIWA-sponsored fair and this year projects include a system that senses the rain and covers your clothesline and a programmed fish feeder to look after your fish when you are on holiday.
Kelvin Hogg, chair of the science fair committee and head of science at Hamilton's St Paul's Collegiate, says he is always impressed by the enthusiasm and passion students show for science when they talk about their projects.
"Wandering around the fair last year, I saw some real gems of projects where you were completely mesmerised by what the kids had done,"
Mr Hogg said he hoped that this year would see a stronger focus on sustainability issues, such as recycling and reuse of materials.
"That's a huge global challenge for scientists to get their heads around in the future. As a small developed country, New Zealand should be leading the world in sustainability. Science and technology is the best way for this country to move forward; by creating innovative new products and ways of doing things that the rest of the world wants to buy."
The NIWA Waikato Science and Technology Fair is being held at Hamilton Gardens pavilion and is open to the public on Friday from 9am to 6pm and on Saturday from 9am to 2pm. Admission is free.
A team of judges, including scientists, educators and industry representatives, will award more than $4500 worth of prizes across a range of categories, including a $500 award for Best in Fair and $300 for the runner-up.
NIWA also offers a work experience scholarship for a senior student offering the winner paid work experience at NIWA in Hamilton.
Prizewinners will be recognised at an official prizegiving ceremony on Friday, 23 August at the PWC Lecture Theatre, Waikato University.
NIWA wishes all students entering the fair the very best of luck. NIWA is also a major sponsor of the Auckland, Manukau, Bay of Plenty, and Wellington Science and Technology Fairs.
