  1. Select one of the three cells pictures at the top of the screen and drag it into one of the beakers.
  2. Observe the process of osmosis. Determine whether water represented by animated blue arrows, moves into, stays in equilibrium, or moves out of the cell. Observe what happens to the shape and size of the cell.
  3. Record your observations in the table below.
  4. Move the cell to a different beaker or choose a different cell. Observe the process of osmosis again and record your observations in the table.
  5. Repeat this activity with all three cells and all three solutions.
  6. Answer the 5 conclusion questions below
