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. Which solution(s) is saturated? What is the evidence of saturation?
Reference answer: Mixtures 4 and 5 are saturated. There is material on the bottom of 4 and 5.

Student answer: Mixture 4 and 5 because it has the precipitate at the bottom of the cup.

Student answer: 4 and 5 because you see material on bottom.

Student answer: The ones that are saturated are mixtures 4, 5.

Student answer: Clear nothing on bottom.

Student answer: It is chemical reaction.

Student answer: Mixtures 4 and 5 are saturate because there is material on bottom.

Student answer: Solution 4 and solution 5. The cup has material on the bottom.

Student answer: 4 and 5 are saturated because there is material on the bottom that will not dissolve.

Student answer: Solution 4, 5. Saturation is when you can see some material on the bottom.

Student answer: 4 and 5 because there is material on the bottom.

Student answer: Mixture 4 and mixture 5 are saturated. When water cannot hold any more of a solid, when you try to add more, it falls to the bottom. That happened in both mixture 4 and 5 so they are both saturated.

Student answer: I forgot what that means.

Student answer: Mixture 4 and mixture 5. It is when particles is sitting at the bottom.

Student answer: Mixture 4 and 5 are both saturated because they have material on the bottom.

Student answer: Mixture one, 2, and 3 because they are clean on the bottom.

Student answer: 4 and 5 because there stuff on the bottom.

Student answer: Mixture 4 and 5 because there is no more space to dissolve so it is saturated.

Student answer: 4 and 5 are saturated because there is solid on the bottom.

Student answer: 4 and 5 because he has clear water and material on the bottom.

Student answer: 4 and 5 because there is stuff at the bottom.

Student answer: Material 4, 5 has stuff on the bottom.

Student answer: 4 and 5. There is material on the bottom.

Student answer: Solution 4, 5 has some material.

Student answer: 4 and 5 because they have material on the bottom.

Student answer: 4 and 5 are saturated because there stuff on the bottom.

Student answer: 4 and 5 are saturated because that is solid at the bottom.

Student answer: Mixture 4 and 5 because there is material at the bottom.

Student answer: 4 and 5 because there is a solid at the bottom.

Student answer: Cup 4 and 5 they are the material at the bottom so they are saturated.

Student answer: Mixtures 4 and 5, the evidence is that there is material at the bottom and that means it is saturated.

Student answer: 4 and 5. Material on the bottom.

Student answer: I think mixture 4 mixtures are.

Student answer: Mixture 4 and 5. The material at the bottom.

Student answer: Mixture one and 3 because they are both clear and have no particles on the bottom.

Student answer: Solution 4 and 5 because there is material on the bottom.

Student answer: Saturation means stuff at the bottom.

Student answer: 4, 5 there is solid at the bottom.

Student answer: A mixture that still has stuff at the bottom.

Student answer: None because I do not think solid and water make a solution.

Student answer: Solutions one and 3.
