Separating Mixtures

We have begun our Chemistry unit. Yesterday and today we investigated mixtures. A mixture is a combination of 2 or more substances in variable amounts in such a way that they are not chemically combined.
We tried to separate the mixtures using mechanical means, i.e. picking out with tweezers, sifting, using a magnet for the magnetic items, filtering, and evaporation.
