A class of super scientists continued their investigation into the properties of materials.
The groups were tasked with separating different mixtures of materials. We had already successfully separated a salt water solution the week before using evaporation, leaving us some seriously salty crystals. In this lesson the children separated different sand based mixtures. We used our prior knowledge of solutions and dissolving to make the correct prediction around how to separate sand and water using a filter paper – this also involved an explanation as to how Mrs Smith’s flask of delicious coffee is made each day!
