Today, we mixed together different ingredients with our water. Some mixtures dissolved, while others did not. We added 1 tablespoon of citric acid into 100Ml of water. The citric acid broke apart into little pieces when it was mixed with water. You couldn't see the citric acid, but there was still 1 tablespoon of it inside the water. The pieces were so small because they dissolved in the water. The salt also dissolved in the water. The sand, pebbles, oil, and baking soda didn't dissolve.
Look at this picture of lemonade. Some ingredients dissolved in the water, while other ingredients did not dissolve. Which ingredients dissolved, and why? Which ingredients did not dissolve, and why? How could you separate all the different ingredients in your lemonade?

ReplyDeleteEmily,
If you started with hot water, would more or less sugar dissolve?
Mr. Burken,
ReplyDeleteWe think the sugar will dissolve faster with hot water, because the particles are moving a lot in the hot water.
We are going to try it out on Tuesday. When we dissolved salt with our hot water, the salt dissolved faster, and we could dissolved more salt. We think the same thing will happen with sugar, but we want to try it!
From,
Ms. Lopez's class!
