Today we started a science unit on Mixtures and Solutions. We learned that a "mixture" is two or more materials stirred together. A "solution" is a special mixture that happens when a material dissolves in water. We made mixtures out of water and gravel, water and powder, and water and salt. We also learned that the materials in a mixture can be seperated. We used filters to try to seperate our mixtures.
Hmm. The screen seperated the gravel from the water. The filter seperated the powder from the water. How can we seperate the salt from the water?
