Salt and water

We are working with solutions and mixtures. Today we talked about the difference between a solution and a mixture. We added sugar in hot and cold water and drew atoms and ions.
Then the class had to find out if you can resolve how much salt as possible in a glass of water.

Lucas and Samuel mixed with salt until they get a saturated solution.

We then used the salt solution to paint on black paper and came up with fine artwork.
