Complete all 5 parts of the Lab Presentation.

Lab Helpful hints:

This is a great lab for showing how molecules move across a semipermeable membrane. However, there are a couple of spots where there is a problem with the programing. Follow these instructions to make the lab run properly.

In section 2, where she has you drag and drop the water molecules, it doesn't work. Skip that step.

In section 3, when you try to place the tube into the centrifuge, it won't balance. Click the skip forward arrows one time, located on the bottom of the screen. This will move it to the next part of the experiment.

In section 4, when you place the tubing into the solution, nothing happens. Again, click the skip forward arrow one time, and it will continue the experiment.
