“The best day ever” was how students of Rushall NS described their visit to the RDS Primary Science Fair at the BT Young Scientist Competition to show their project “Are our hands really clean?”
Principal Anne Bergin described their experiments.
“We grew bacteria in Agar and tested different soaps and gels to find out which was most effective at killing the germs.
“We surveyed local schools on hand-drying and interviewed our pupils to see when they felt it most important to wash hands,” she said.
They discovered most were “very good at hand-washing after the toilet, but not so good before eating and after handling animals”.
They also did a workshop with soap maker Sheila Heyden from Bumblebliss.
Investigating hand-washing in Third World countries, they found the Tippy-Tap, a hygienic way of hand-washing with no running water, making a model that much impressed the judges.
The children had fun explaining their investigations to the public, later viewing other projects and taking in a drumming workshop.
“The positive feedback from the judges will hopefully stimulate some budding scientists from Rushall NS.
“The icing on the cake came when the children were presented with a trophy,” said Ms Bergin.
