18 Oct Year 5
Year 5 are continuing their science investigation looking at reversible and irreversible changes. We completed an experiment to see how we can reverse a salt water solution through evaporation. We observed the effects of different liquids and solids on metal, we found out that through oxidization, metal begins to rust, which is an irreversible change. We also completed an experiment on the irreversible change and chemical reaction of bicarbonate of soda and vinegar.
