X26 Admiral were in the lab yesterday focussing on separating mixtures. This is part of our investigations for two case studies looking at how soldiers in the trenches could clean dirty water and how they could avoid harm during a mustard gas attack.
In this session we separated sand and salt by first mixing with water. Since sand is soluble, we could then filter to separate the sand. Following this we used an evaporating basin to separate out the salt.
Every member of the class achieved some great results and managed to separate the sand from the salt.
Here are Mollie and Becky with their finished experiment and Hubert’s prediction of what would happen:
