Grade 7 is working with salts and experimented today with colors when various salts, such as lithium chloride are on fire. To start fire we used methanol.
Beautiful!

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.
