Class 4 was invited to Kingston University to be scientists for the day! They learned about states of matter and different methods to change the states. We experimented with what we had learned through three experiments. The first was testing different ways to measure the amount of gas produced when mixing vinegar and baking soda. The second was exploring the state that is somewhere between liquid and solid through slime-making. The last was changing milk into plastic through a chemical reaction and heat.
