Science puts on a show
Seeing a gherkin electrocuted had pupils enthralled at Dilworth Junior School earlier this month.
The presentation was part of the Science Roadshow’s Auckland tour this term.
The Arks, Sparks and Gherkins show looked at electricity and the different materials that act as conductors.
Children were surprised to learn that the minerals in tap water mean it can conduct electricity, as can the inside of a pencil.
One brave teacher volunteered to sit in the Electromagnetic Chair of Doom – expecting to go crashing to the floor when the power was switched off. He was relieved to find he was saved by a bungy.
The Pantry Show involved a range of demonstrations from the kitchen, with many able to be safely reproduced at home.
Pupils explored interactive exhibits on the themes of light, heat, sound, earth science, astronomy, magnetism and health and wellbeing.
They measured their muscle mass and water proportion, experienced hurricane winds and whispered to friends across the hall.
The National Science-Technology Roadshow Trust is in its 20th year. Last year more than 50,000 students nationwide saw the roadshow.
Students at Tamaki College will enjoy the show tomorrow and on Friday.
During the school holidays the roadshow will be set up at the Museum of Transport and Technology (Motat) in Western Springs.
