Year 4’s Science topic is States of Matter. We have been learning about fair testing and planned a test which we kept all variants the same apart from one. Our test was to discover what would melt first; butter or chocolate. We discovered that butter melts faster than chocolate. We also discussed that both butter and chocolate had to be heated to melt. Which changed the state from solid to liquid. Some children even identified that when the butter sizzled it produced a gas!
After some time we looked at the butter and chocolate again and saw that the state had been reversed back to a solid as it had cooled down.
