Science Week in 5th Class


5th  Class demonstrated closed circuit electrical experiments  using batteries, wire and bulbs . They also had a potato powered calculator. Robert explained it was to do with the chemical reactions inside the potato could be diverted to a calculator by adding copper and metal. We also saw battery operated spinning fans and rainbow coloured discs that produced a white colour when spinning. Eve used her c programming skills to program a chip which allowed her to make a small “robot” move.  James had an experiment to show liquids of different densities don’t  automatically mix . Hugh had a gravity and water experiment . Andrew showed dissolving gummy bears and bicycle gears and Luke crated a very impressive doodle bot.  Well done to all.
