Question: Shanna stuck one end of a clear straw into a ball of clay. She filled the straw part way with water and marked the water level. She then placed it in the freezer. Which statement describes the level of the water (ice) in the straw after it froze? (Circle the one best answer.) A. The water level went down when the water froze. B. The water level stayed the same when the water froze. C. The water level went up when the water froze. Explain your answer.
Reference answer: The level went up when the water froze because water expands when water freezes.

Student answer: It stayed the same because there was something that was covering the bottom.

Student answer: When Shanna put the straw into the freezer the water level went down because cold water is less dense so the level went down.

Student answer: When water freezes it contracts then expands.

Student answer: When the water freezes the water molecules are trying to be the warmest so they huddle together then expand.

Student answer: Because if you put ice in water it makes water level go up.

Student answer: Because when water freezes it goes up.

Student answer: Because the water is less dense.

Student answer: When water freezes it expands.

Student answer: The water level went down because the water molecules come together and the water level goes down.

Student answer: I think it stayed the same because all it did probably just stayed the same and suddenly it froze.

Student answer: Because the water makes the water more flat.

Student answer: When water freezes into ice, it expands.

Student answer: Because when I put my water in the fridge or freezer.

Student answer: It goes down because it was so cold.

Student answer: Ice has bits of air in it and expanded.

Student answer: When water gets cooler it contracts.

Student answer: C because it like needs to come into place.

Student answer: When water freezes it expands therefore making the water level expand.

Student answer: I choose C because whenever I freeze some water in cup it expands.

Student answer: The water contracted because the water was cold there water would of expanded if it was hot.

Student answer: Water expands when it is frozen into ice.

Student answer: The water level went up because when water freezes it expands.

Student answer: When water freezes it expands so the water level had to go up.

Student answer: When water freezes it contracts and gets smaller.

Student answer: The reason I chose A was because when water freezes the temperature drops which make the water turn into a solid.

Student answer: When water is frozen it expands which makes it go higher.

Student answer: When water freezes it expands.

Student answer: The water probably went down because it was probably colder than the other water.

Student answer: Because the temperature that is cold is at the bottom.

Student answer: When it gets colder the water level goes down.

Student answer: When water freezes it turns to ice, ice expands. So it went up.

Student answer: Because the soapy water had less water.

Student answer: It went down because cold contracts when it is cold in the freezer or something else.

Student answer: The water contracted because it was less dense.

Student answer: Because the water was dense.

Student answer: Water expands when freezes.

Student answer: When it is cold the water in the straw will go down before it freeze.

Student answer: Because water expands when you freeze the water and the water goes up.

Student answer: The water level will go up because when it freezes it goes up.

Student answer: When water is frozen it expands.

Student answer: Because it cannot go down.

Student answer: When water gets cold the temperature drops.

Student answer: When the water froze it evaporated and the temperature dropped.

Student answer: When it froze it went down.

Student answer: Because it stayed the same.

Student answer: Water get froze it took more space.

Student answer: When water freezes it expand and takes up more room.

Student answer: Because water expands when it freezes.

Student answer: Water expands when it is frozen.

Student answer: When water freezes it expands meaning there is more space between the molecules.

Student answer: Because cold water expands and needs more space, so it goes up.

Student answer: When water freezes it expands, so the water level went up.

Student answer: When water froze it is a expand more rooms.

Student answer: The water expands when it is frozen.

Student answer: Ice is more dense and takes up more room. When it froze, the ice needed more room so it went up.

Student answer: Water level went up because when water freezes to ice it expands or goes up.

Student answer: The water level went up because when water freezes it expands.

Student answer: Cold water expands when it freeze.

Student answer: The water level went up when the water froze because it expanded.

Student answer: When water freezes it expands.

Student answer: Because when water freezes, it contracts so the level went up.

Student answer: The ice goes up because it needs more space.

Student answer: Water expands well it is freezing.

Student answer: When water freezes it expands.

Student answer: It went up because when water freezes it expands.

Student answer: When water freezes it expands.

Student answer: Ice contracts so it would be lower.

Student answer: Because it stays in one spot and freezes in one spot.

Student answer: Ice expands.

Student answer: The water level went down because the water contract.

Student answer: When water cools it condenses but when it reaches a certain point it starts to expand ice.

Student answer: Ice expand when it hit the freezing point.

Student answer: The water expand and goes down then expand again.

Student answer: The water went up because when water freezes it expands or gets bigger so it would go up.

Student answer: Cold water contracts but when it hits freezing it expands, so the water level rises.

Student answer: When water freezes it expands.

Student answer: Whenever something freezes it expands.

Student answer: Because it froze.

Student answer: Water has some air so it goes down.

Student answer: When water freezes it expands.

Student answer: Because It froze and spilled.

Student answer: When water freezes it bulges and makes it taller and wider.

Student answer: Because when you put it in cold it still evaporates but then it freezes.

Student answer: Ice has density at a high level so contracts when changes from liquid to solid.

Student answer: Because the ice expanded in a closed bottle of water the bottle would just crack or get stretched out but in the straw there was more room to move so the level went up.

Student answer: Because when I make Kool-aid I put it in the freezer it is always goes down.

Student answer: Because when she put it in the freezer and froze and expanded.

Student answer: When water freezes it expands.

Student answer: Because we talked about this in class when you put it in the freezer some water evaporates.

Student answer: Because it takes a very long time for water to evaporate just a little.

Student answer: Because coldness makes things go down.

Student answer: Because it froze not going anywhere.

Student answer: When it froze it expanded.

Student answer: Because cold water is dense and it also sinks, so it goes down.

Student answer: Because when water freezes it turns into ice. And it is cold.

Student answer: Because it expand and the water level goes up.

Student answer: The water could not go down because it freeze and it could not go down either.

Student answer: Because when water was frozen it could not move.

Student answer: Because the water soaked through the clay a couple of times. It went down a little.

Student answer: When ice froze it expanded and went up.
