In Mrs. Frizzle’s science classroom, she sets up a beaker as shown in the illustration shown; there is a bag filled with a glucose solution (glucose and water) within a beaker of the same solution at a different concentration. The bag is permeable to water but not glucose. One student, Ricky, is working on the problem and draws his arrow showing the movement of water into the bag. Another student, Cindy, disagrees with him. Cindy says the arrow should be showing the movement of water out of the bag. Which of the two students is correct? Explain why.
