Question: Joanne mixed material R and material D together, added water, and stirred. After a few minutes, the liquid was clear and there was a solid on the bottom of the cup. Joanne used a paper filter to separate the solid from the liquid. Why does the solid stay in the filter when the liquid goes through?
Reference answer: The particles of the solid are too big to go through the holes in the paper filter.

Student answer: The solid was too big to go through the filter paper.

Student answer: Because the little piece of the liquid and the undissolved is bigger.

Student answer: It is separate because the paper filter is liquid.

Student answer: Because the solid is too heavy to go through the paper.

Student answer: Solid is too big to go through the filter hole. Liquid is just water that can go through almost anything.

Student answer: Because the filter cannot hold the water because the filter already has water in it.

Student answer: The holes in the filter are smaller than the solid particles, and the water particles are smaller than the holes, so the water goes through the filter while the solid will not go through.

Student answer: Because the particle size was too big and the filter could not hold any more water because it was wet.

Student answer: Because when the solid touches the side, it sticks.

Student answer: Because the solid was bigger than the liquid so it got stuck!

Student answer: Because she did not wet the filter and when she put the water they got wet.

Student answer: Because the materials are too big to go through the holes but the water is not too big to go through the holes in the filter.

Student answer: It stays in the filter because the solid material does not count as the solution.

Student answer: The solid does not go through the filter like the liquid because the liquid is small enough to go through the filter but the solid is too large.

Student answer: Because it is a thick.

Student answer: Because the holes in the filter are too small for the solid to go through them.

Student answer: The solid stayed in because it was too big to go through the microscopic holes in the filter paper.

Student answer: The solid stays in the filter because the particles are too big to go through but dissolved can go through because the particles are small enough.

Student answer: It stays at the top because it is too big to go through the filter and the water is just a liquid.

Student answer: The solid is hard. It cannot go through because it is not a liquid.

Student answer: Because the solute in the saturated solution dissolved and were dispersed equally. The material that did not go through was too big to go through.

Student answer: Because the materials are stuck together with water and cannot go through the tiny holes in the filter.

Student answer: Because when the water goes through the filter some water stays which helps the filter catch the sugar.

Student answer: Because it is too thick to slide down the filter.

Student answer: Because the solid stay because it is too big and water it can just go through things like that.

Student answer: Because they are big.

Student answer: The solid stayed in because it was not as watery and it was bigger chucks. The liquid is watery and so it went through.

Student answer: The solid stays in the filter because the filter's holes are too small for the liquid to go through.

Student answer: Because paper absorbent and solids cannot go through solids.

Student answer: The liquid was too big to go through the holes.

Student answer: Because in the filter paper there are little holes!

Student answer: The solid would be too big to pass through the small holes in the filter paper.

Student answer: The solid stays because its particle size was too large to go through the filter.

Student answer: Because water goes through the paper and the salt is not water.

Student answer: Because the liquid is a substance that can go through most objects with small or tiny holes and solid cannot.

Student answer: Because the solid did not dissolve.
