Growing Crystals

For their Science Fair investigation Laura, Kupakwashe and Nooroa wanted to find out in which condition did crystals grow the fastest. They used one cup of boiling water and three tablespoons of copper sulphate to grow the crystals. They mixed three solutions and put it into three jars. They put one jar in a dark room, one in a fridge and one in the sun. Sabrina interviewed Kupakwashe and Laura to find out what they did and what happened. View the video below to find out where it grew first. Please leave a comment for us.
