As part of our Science unit, Properties and Changes of Materials, Year 5 have been busy planning and conducting experiments to find out all about solubility. They have been experimenting with sand, salt, sugar, chalk and coffee granules to see which substances dissolve and which are insoluble.
The results were followed up with further experiments to investigate how (or if!) we could separate the substances that we dissolved by the processes of evaporation, filtration, sieving and magnetism. We had some interesting outcomes and lots of fun predicting and finding out whether the changes would be reversible or irreversible.
We are looking forward to more experiments and investigations in the summer term as we begin our new unit on Earth and Space.
