Bellwork: Monday September 9th, 2015
1. Write down any ideas you have on how you
would set up an experiment to show how osmosis
works.
•
You will have the following to work with:
• 2 beakers, distilled water, soda, starch water,
tubing(acts like the cell), salt water, glucose,
sucrose

Get in assigned groups
Listen to directions!
• Hypertonic Solutions: contain a high concentration of solute
When a cell is placed in a hypertonic solution, the water diffuses
out of the cell, causing the cell to shrivel.
• Hypotonic Solutions: contain a low concentration of solute
When a cell is placed in a hypotonic solution, the water diffuses
into the cell, causing the cell to swell and possibly explode.
• Isotonic Solutions: contain the same concentration of solute
When a cell is placed in an isotonic solution, the water diffuses
into and out of the cell at the same rate. The fluid that
surrounds the body cells is isotonic.
Diffusion and Osmosis Lab
Reminders:
1. Write down the
amount of each
material that you use
2. Keep track of your
procedures (the steps
you followed)
3. Wash out your
graduated cylinders
after each use
4. Label your beakers
(lab table # and
period)
When finished setting up:
1. Wash every thing you used
except the beakers
2. Clean up your lab area
3. Work on your Osmosis lab
questions
Due Tuesday 9/15
1. Osmosis lab questions
2. Typed osmosis lab report;
must include:
• Question, Claim(Hypothesis),
Materials, Procedure,
Conclusion(Findings)
