In our Science context we are learning about changes in materials.  Today we made observations about what happens when substances are added to water.  We mixed salt, flour, soil and sand with water and found that the salt dissolved but the others didn’t. The next step was to investigate the filtering process to separate substances from water.  This helped us to understand more about the differences between soluble and insoluble substances.  Our next step will be to use our notes and findings to write up our experiments.
