The document describes an experiment on osmosis using eggs. It explains that one egg was placed in corn syrup and one in water, and they were weighed and measured before and after. After 24 hours, the egg in water had gained weight and increased in size, while the egg in corn syrup lost weight and decreased in size, showing that osmosis caused water to move across the eggs' membranes toward the higher concentration areas. The results supported the hypothesis that osmosis would cause swelling in the water egg and shrinking in the corn syrup egg.

2. • To observe osmosis in a
cell.
1. Place egg in vinegar to
remove shell.
2. Measure the weight of
the eggs.
3. Measure the size of the
eggs.
4. Place one egg in corn
syrup and place the
other egg in water.
5. Weigh and measure the
eggs again.

3. • 2 eggs
• 2 beakers
• Corn syrup
• Vinegar (acid)
• Water
• Balance
• String and measuring
tape

4. Water Egg
• Weight: Heavier
• Size: Larger
• Look: More round or
oblong

5. Corn Syrup
• Weight: same
• Size: same
• Look: same

6. Before After
Corn Syrup W: 71.3 g W: 48.8 g
S: 17 cm. S: 13 cm
Water Egg W: 62.2 g W: 77 g
S: 14cm S: 18.5 cm

7. Vinegar and egg
• Bubbles were coming
up
• Eggs in bottom
Water egg after 24hr.
• Larger
• Heavier
Corn syrup after 24hr.
• Puffy
• smaller, lighter

8. Water Egg
• got larger- water
moved to the egg
• egg: lower
concentration
• water- higher
concentration
• Water went from
higher (water) to lower
(egg) concentration

9. Corn Syrup
• got smaller- water
moved out of egg
• egg: higher
concentration
• water: lower
concentration
• Water went from
higher (egg) to lower (
corn syrup)
concentration
