What is high concentration to low concentration?

I thought it was moving from an area of more stuff to an area of less stuff, but we did an experiment in class and the water from the beaker moved into the dialysis bag of sucrose solution. I don’t understand why. Doesn’t the sucrose solution have a higher concentration, so should it not be moving out to the water?
I am so confused. Please Help!

If you have two solutions, one with high sucrose concentration and one with low sucrose concentration the two solutions will “want” to be equal in concentration. This can mean either that the sucrose itself moves (diffusion) or that the water moves (osmosis). The sucrose will move from an area of high concentration to an area of low concentration so that the concentrations are equal. The water will move from an area of low concentration to an area of high concentration. This will also make the concentrations equal because the water is diluting the high concentration solution. In your experiment, the water moved into the dialysis bag because dialysis bags are impermeable to sucrose (sucrose can’t move through the membrane of the dialysis bag). Thus the sucrose could not move so the water had to.
