Title: Osmosis with an egg lab
Slide One
• Problem: how can we observe osmosis across a semi-permeable membrane
• Background: certain substances are ble to break down the egg shell leaving the transparent layer. Other substances can either make the egg shirnk or make it expand.
Slide Two
• Hypertonic: a higher osmotic pressure in one fluid than the other in the intercellular liquids.
• Hypotonic: a lower osmotic pressure in one fluid than the other in the intercellular liquids.
• Isotonic: having the same osmotic pressure throughout the intercellular liquids
Slide Three
• If an egg (cell membrane) is placed in a hypertonic   environment then the water will dissolve from the egg and the egg will shrink in size.
• If an egg (cell membrane) is placed in a isotonic environment the water will not affect the egg and the egg will stay the same.
• If an egg (cell membrane) is placed in an hypotonic environment then the water in the in the egg will be pushed to the top forcing the egg to expand.
Slide Four
• Quantitative- texture, visual size, smell.
