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

Bellwork: Monday September 9th, 2015

Agenda: 1. Turn in reading logs from Friday

2. Watch review videos• Amoeba sisters• Experiment set up

3. Quick review

4. Get in assigned groups

5. Listen to directions!

Diffusion and Osmosis Lab

• 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.

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)

Diffusion and Osmosis Lab 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
