Diffusion
" Winston's Science teachers and technicians always trying to bring something new and exciting to the students. Last week , Mr Spain's year 7 classes were lucky to experiment with diffusion in micro-scale. They observed the diffusion as the colour change took place front of them."
Reaction Rate of Catalysts
"On Friday, 10W3 investigated the reaction rate of catalysts. Mr Rose adapted the iodine clock demonstration into a class practical with the help of the science technicians. The class was able to observe the time difference between the use of catalyst and non-catalyst by turning a solution from a milky colour to black and timing the reaction rates. "
Effects of Silver Nitrate on Copper
" This week , 9C2 and 9W3 investigated the effects of silver nitrate on a coiled copper wire. The students in Mr Philcox's class witnessed the slow process of the copper wire dissolving in the silver nitrate solution. The precipitate is pure silver metal , showing like little silver tree branches on the copper wire. "
