Science Gets a Reaction in Key Stage 2
Key Stage 2 have been learning about chemical reactions in their Science work this term. They have looked at how everything in our world is made from tiny particles and how sometimes these particles can react together to make a new substance. The children have found out that chemical reactions happen every day, from lighting a match to baking a cake, and that reactions take in and give out lots of energy in the form of heat, light or even sound!
This week the children mixed some rhubarb with some Potassium Permanganate and found that it changed the colour from purple to clear. They then investigated if changing the surface area of the rhubarb, by cutting it up into smaller pieces, would change the speed of the reaction. Yet another example of the brilliant practical Science which is taking place at Tindal!
