Over a two week period J6R investigated ‘Reversible and Irreversible Changes’.
They dissolved coffee and sugar using a Bunsen burner and recorded the temperature at which this process occurred. Then using filter paper and a funnel, the following week, they filtered the mixture to collect a solution and gather the larger particles which could not dissolve. Following this the liquid had to be evaporated so the liquid formed a vapour leaving a solid material again.
The results; pupils enthused by experimental research and an enthusiasm for investigation and a thriving ambition to learn.
