Question: What does water do in a osmosis operation?

Procedure: Have two beakers, salt, water, two dialysis tubes, and a weight . Fill one of the beakers with salt and water and one beaker with just water. Grab a dialysis tube and pour salt into it the dialysis tube then grab another dialysis tube and pour water into it. weigh the two dialysis tubes before you put it into the the beaker then put the one with just salt into the beaker that has just water and then the dialysis tube with just water put it into the beaker with salt and water. Then after a day take the two dialysis tubes out of the beakers and weigh them again. The dialysis tube with salt should weigh more than the dialysis tube with just water.

Claims: The dialysis tube with salt weighs more than the one with water because of osmosis.

Evidence: 

Research: Osmosis is when molecules move through a semi permeable membrane into a region of higher solute concentration, in the direction that tends to equalize the solute concentrations on the two sides.

Reflection: I learned how osmosis can affect a cell membrane.
