Discussion and Conclusion - seperation of a mixture
For example, when separating the iron, salt, and sand mixture we were able to use a magnet to remove the majority of the iron from the mixture. This form of physical separation works because even though the components are mixed together, they retain their own characteristics, so iron remained magnetic even though it was a part of the mixture.
