Yesterday in Class 4, we investigated separating mixtures. We separated raisins and flour using a sieve. This worked because the raisins are larger than the holes in the sieve. The rice and paper-clips were separated by a magnet, as paperclips are magnetic. We decided to put the salt and water into an evaporating dish and left it over night. He are some photos of the results:
The water evaporated and left us with the salt.
