In Sarah R’s Class we have continued to investigate the properties of materials in science. We thought about how we could use the properties to separate different materials in a mixture. We used magnets to remove metals. We used filters and different size sieves. We then challenged ourselves with how to remove salt from saline solution. We realised that we needed to apply our water cycle knowledge and evaporate the water. We carefully heated the solution and observed the changes until we were just left with salt.
