Question: Jim used a solid and water to make Mixtures one (one spoon of solid in 100 milliliters water was clear with nothing on the bottom), 3 (3 spoons of solid in 100 milliliters water was clear with nothing on the bottom), 4 (4 spoons of solid in 100 milliliters water was clear with material on the bottom), and 5 (5 spoons of solid in 100 milliliters water was clear with material on the bottom) as shown below. He stirred each one and observed the results. If Jim made Mixture 2 with 2 spoons of solid in 100 milliliters of water, what would he observe? What evidence do you have to support this?
Reference answer: Jim would see a clear solution. 3 spoons of solid dissolves, so 2 spoons will dissolve.

Student answer: There would be a clear liquid with no solid on the bottom.

Student answer: It is going to be clear at the bottom and you will not see anything and I know this because if it does not dissolve in mixture it will not dissolve.

Student answer: It has been a little different.

Student answer: Clear, mixture 3 is clear.

Student answer: He would observe that the water is not saturated yet because a mixture 4 it get saturated.

Student answer: It would be a solution. One and 3 have either one spoon or 2 spoons of solid in their mixtures and they are still a solution.

Student answer: He would observe nothing you need more spoons to make it saturated. Because mixture 3 has 3 spoons and it is not saturated.

Student answer: He would observe the nothing will be at the bottom.

Student answer: He would not observe anything because nothing happened to the other ones either.

Student answer: It will dissolve in the cup.

Student answer: Clear and nothing on the bottom because one scoop and 100 milliliters of water has the same results and so does mixture 3, 3 spoons and 100 milliliters water.

Student answer: Clear, nothing on bottom because mixture one and 3 are that.

Student answer: Clear with nothing on the bottom. Evidence Mixture 3 has more and is clear with nothing on the bottom and mix.

Student answer: I think that the mixture would be clear with nothing on the bottom, because both mixture one and 3 say that if mixture 3 is not saturated and has more material than 2, 2 would not be saturated either.

Student answer: It would not have any particles at the bottom.

Student answer: That the solid dissolved in the solute! That with one spoon. It is clear and with 3 spoons it is clear so the solid will dissolve in the solute!

Student answer: If mixture 3 is dissolved, and mixture one is not dissolved. Mixture 2 will not be dissolved because it is less concentrated than mixture 3.

Student answer: He will see clear and nothing in the bottom because you cannot see nothing in 3.

Student answer: It would dissolve because he has so much water there would be enough space to dissolve the solid.

Student answer: Well if solution 3 has more materials and it is dissolved the evidence he would have is solution 2 will be dissolved too.

Student answer: That the solid dissolves because one, 3 dissolves.

Student answer: It would dissolve because 100 milliliters of water gives the solid more room to dissolve.

Student answer: The solid would dissolve because so did solution one and 3.

Student answer: When he put the 2 spoons in the 50 milliliters in of water he will get 2 times for water then mixture.

Student answer: 2 spoons of solid and 100 milliliters of water and it was clear material on the bottom.

Student answer: That there is one dg. one spoon is 5 grams.

Student answer: It would look clear and who have nothing on the bottom.

Student answer: Well It would be clear because 2 has more solid and is still clear.

Student answer: I think he would see the solid dissolve.

Student answer: Mixture 2 maybe clear with nothing on the bottom.

Student answer: He would observe the solution clear and nothing at the bottom because one and 3 do not have anything at the bottom and if 3 does not have any solute at the bottom 2 would not either.

Student answer: He would observe fizzing in the cups. To evidence this you would put a lot of things in both of the cups.

Student answer: Nothing will be on the bottom and it will be clear. Because solution 3 has nothing on the bottom and it is clear.

Student answer: There would be no material of bottom because mixtures does not have any material on bottom.
