Question: Ted poured the same amount of water into 2 small containers, X and Y. He placed them together where they would not be disturbed. After several days, all of the water had evaporated from one of the containers. The other container still had some water. Which container, X or Y, was empty? Explain why the water in that container evaporated more quickly than the water in the other container.
Reference answer: Container X has more surface area or more water exposed to the air so the water evaporated faster.

Student answer: Because X had more room to evaporate and Y did not.

Student answer: The water in container X had a more open space to evaporate, so it evaporated. The water in container Y could not evaporate because it did not have an open space to evaporate.

Student answer: X evaporated more than Y because container X has more surface area than container Y so it evaporated faster.

Student answer: There is more surface area on container X so more water could evaporate at one time.

Student answer: The water in X evaporated because the more surface area the more air can get to it to make it evaporate faster.

Student answer: X evaporated faster because it has more space to evaporate quicker.

Student answer: The water in container X evaporated more quickly than the water in container Y because in container X there is more wide and open, so the water evaporated faster, but since the container for cup Y was closed and not open very much, then the water evaporated slower.

Student answer: The water in container X evaporates faster because the container has more surface area.

Student answer: X because X has more surface area and if you have lots of surface area it will evaporate faster.

Student answer: Container X had a bigger surface area, causing the water to evaporate more quickly.

Student answer: The X container has more surface area than the Y container.

Student answer: It evaporated faster because there was more room in the container and it's a wider cup. It had more room to evaporate faster.

Student answer: Well, if there is a bigger surface area then the water will evaporate more quickly.

Student answer: Because the surface area was wider.

Student answer: I believe X evaporated more quickly because X has more space and Y does not.

Student answer: It is wider.

Student answer: Because cup X had more surface area, which makes it easier to evaporate.

Student answer: It evaporated more quickly because there was more surface area.

Student answer: The surface area of container X is bigger, causing it to evaporate faster.

Student answer: Because the surface area was wider so it had more room to evaporate.

Student answer: That water moved more quickly because it had a larger surface area causing it to evaporate faster.

Student answer: X has a bigger opening on the top of it.

Student answer: Because it has more area but Y does not.

Student answer: Container X evaporated quicker because it had greater surface area. So more water molecules were exposed to the air, so they evaporated quicker.

Student answer: X had more room and more gate that is how.

Student answer: The water in the X container had a larger surface area. Which let it evaporate more water faster.

Student answer: It evaporated quickly because it had a larger surface area.

Student answer: Because X had more surface area than Y.

Student answer: X evaporated more because it has more room for the water to evaporate.

Student answer: Because the cup Y is larger it is tall so it would have to evaporate and X is not tall so it will not evaporate as quickly.

Student answer: Because it has a bigger surface area so it will evaporate faster.

Student answer: The container was more denser.

Student answer: X was empty because it has surface area.

Student answer: Y is more skinnier so it does not have enough room to evaporate so X is wider so it has a lot of room to evaporate.

Student answer: Because it does not have as much surface area.

Student answer: Because it has more room space where the water could evaporate faster.

Student answer: X had more surface area. So most of X water had evaporated.

Student answer: Because container X had more surface area.

Student answer: X had more surface area.

Student answer: Why I picked the letter X is because of the surface area. It has to be wider than a milk carton.

Student answer: Because it had a bigger surface area.

Student answer: Y is hollow so there is not a lot of room for it to evaporate and X is wide so it would be able to evaporate more quickly.

Student answer: Because X has a wider opening than Y so the evaporation will get to X quicker.

Student answer: Because X is fatter than Y and Y is tall so the water on the bottom will not evaporate.

Student answer: Because the water in Y was more heated.

Student answer: Because there was more surface area.

Student answer: Because the container X had more surface area, and the more surface area the faster it evaporates.

Student answer: Because that water has taken before so that water evaporated more quickly than the other.

Student answer: X was exposed to the air more and had more surface area than Y.

Student answer: That one was empty because it had more surface area, so the sun or air could get to it easier. If it has more surface area, the more likely it is to evaporate.

Student answer: X evaporated more quickly because there was more air being exposed.

Student answer: The water in cup X was exposed to more air which allowed it to evaporate faster.

Student answer: Container X had more surface area so it evaporated quicker than container Y.

Student answer: It had a larger surface area.

Student answer: X had a larger opening than the other cup.

Student answer: X evaporated more because X had more land area?

Student answer: The X container has a bigger surface area so it could evaporate quicker.

Student answer: It has more surface area so more air can get to it and evaporate it.

Student answer: Because that container had a bigger opening than the other.

Student answer: X has a bigger surface area so it will evaporate faster.

Student answer: Because X had more surface area than cup Y.

Student answer: Because it had a bigger surface area.

Student answer: Because the surface area is more bigger than the other container.

Student answer: Because X has a larger surface area, so the cup with the larger surface area would evaporate faster.

Student answer: It evaporated more quickly because it had a larger surface area.

Student answer: Because X had more surface area.

Student answer: X because it is the tallest and X is wider but Y evaporated more.

Student answer: The X container had larger surface area.

Student answer: Container X had a larger surface area than container Y.

Student answer: Because X has more surface area and so it will evaporate faster.

Student answer: Surface area affects evaporation X had a bigger surface area than Y so X evaporated faster than Y.

Student answer: Because someone picked it up and drank it.

Student answer: Because it has more area to come out in.

Student answer: Because X has more surface area than Y.

Student answer: Because there is more in the X cup.

Student answer: The container was wider than the other.

Student answer: Because it had more space.

Student answer: Because it has more surface area, room for water to evaporate.

Student answer: Because it had more surface area.

Student answer: Because it had more space in the cup.

Student answer: Because X has more surface area than Y and the more surface tension, the faster the water evaporates.

Student answer: Because maybe he put container Y was put in after container X.

Student answer: The surface area of the X cup was wider than the Y.

Student answer: Because X had more surface area than Y and Y was thin and it will take a bit longer to evaporate.

Student answer: Because Y is deeper than X so it will take longer to evaporate.

Student answer: Because it was spread out more so it evaporated faster.

Student answer: Because each day it only takes what is at the top so X will take less days to evaporate than Y because of the shape.

Student answer: Container X evaporated faster because the water had more surface area which allows more water to evaporate at once.

Student answer: Because there is a smaller surface of the water to evaporate.

Student answer: Because it had more surface area.

Student answer: X had a bigger surface area then Y so it evaporated faster.

Student answer: Because there is more space around the water so it evaporates quicker.

Student answer: The more flatter it is the faster it evaporates and the more fatter it is the longer it takes to evaporate.

Student answer: X has more surface area, so more could evaporate at the same time.

Student answer: Because the container had a bigger surface.

Student answer: X because X has a bigger surface area than Y.

Student answer: Because when something has a wider area the water evaporates faster.

Student answer: Because it had more spot where the sun was hitting so there was more evaporation was going to happen than Y.

Student answer: Because in X it has lots of surface area so it should evaporate faster.

Student answer: The more space you have it will evaporate more.
