In science today, we looked at how to recover materials when mixed in a solution. Group 1 looked at dissolving sugar in water to create a solution. Then we put it into a pan and heated it. The children could see the evaporation process as the water turned into water vapour (a gas). The sugar, however, did not turn back into its original state but remained as a liquid and instead turned into a yellow syrup. When this cooled, it turned into a solid. One child suggested that if a stick were put into it, it would make a lolly. I explained that this is how lollies are made, and that a flavouring and colour are added to make a lolly. This was a science experiment that went wrong. We discussed that some of the best discoveries can happen by accident. The second group made a solution with salt and water. Once this dissolved, it was put on the cooker to evaporate the water and the salt was indeed recoverable once all the liquid had evaporated. The children also explored how to recover sand from water, by filtering a mix of sand and water through filter paper.
