5. Before you continue in the simulation, make a hypothesis and identify the variables in this experiment. Make a hypothesis about the net movement of water for each beaker. Please note that the sugar in this simulation cannot move across the dialysis tubing. Indicate your hypothesis by adding an arrow to each of the beakers in Figure 1. Indicate the net movement of water by pointing the arrow into the cell, out of the cell, or use a double headed arrow to indicate no net movement of water. Beaker A Beaker B α Beaker C Beaker D Beaker E о Correctly identify the following variables: Dependent Variable: Independent Variable: 3 Controlled Variables: Figure 2: Five beakers and cells from osmosis simulation. Confounding Variable: 6. Press the "CONTINUE" button. Record the mass of each dialysis tube as you continue the online simulation. Record these masses at the start (from step 4), and then after "24 hours" in Table 2 (in the Results sections). Calculate the change in weight for each, including a "+" sign for tubes that gained weight, or "-"sign for those that lost weight. Please disregard the 24 hour described in the simulation and replace it with 2 hours. (The rates of osmosis would have leveled off long before 24 hours). 7. OPTIONAL-Press the "CONTINUE" button to answer a few questions.

Transcribed Image Text:5. Before you continue in the simulation, make a hypothesis and identify the variables in this
experiment.
Make a hypothesis about the net movement of water for each beaker. Please note that the
sugar in this simulation cannot move across the dialysis tubing. Indicate your hypothesis by adding an
arrow to each of the beakers in Figure 1. Indicate the net movement of water by pointing the arrow into
the cell, out of the cell, or use a double headed arrow to indicate no net movement of water.
