Today we had a mad scientist day. We make a Volcano from paper and then used Bicarb to create the volcanic eruption. The experiment was a good success however the eruption was not as big as we first had hoped for. The children and I then discussed the experiment, outlining the reasons why the eruption may have occurred the way it did and why certain things (such as Citric Acid, Bicarb Soda and Vinegar) would react the way they did.
We also did a Milk Experiment called ‘Milk Planets’. The idea is to get a saucer of Milk and add drops of colouring into it, Then using an ear bud drop small of dish washing liquid into the milk. The colouring explodes and moves away from the dish washing liquid. This experiment shows the break down of the molecules in the milk when mixed with detergent. The children loved the swirling colours this created. We again discussed how the dish washing liquid separates the molecules and the science behind the experiment.
Great fun was had by all!
