In Science Class . . . . Week of 9/26

This week, we'll be studying phases of matter and saturation. The key experiment will be looking at how much salt can dissolve in 50 ml of water. When the solution is saturated, no more solid (salt) will dissolve and it will remain visible.
Key questions:

• What is a solution? (A mixture where the solid can dissolve in liquid, like salt in water.)
• How did you know your solution was saturated? (The salt couldn't dissolve any more and we could see it at the bottom of the bottle.)
• How did you find out how much salt was dissolved in the solution? (We filtered out the salt chunks and weighed the solution, and then subtracted 50 grams for the 50 ml of water.)
