The student conducted an experiment to observe osmosis in eggs by placing them in corn syrup and water. They measured and recorded the eggs' weights and sizes before and after. The egg in corn syrup got smaller as the higher concentration inside the egg moved into the lower concentration corn syrup. Conversely, the egg in water got bigger as the higher concentration water moved into the lower concentration egg. The student's hypotheses about the eggs' sizes changing were incorrect as they misunderstood which solutions had higher concentrations.

EGG OSMOSIS EXPERIMENT

2. • Observe osmosis in a
cell
• Put egg in vinegar
• Measure with balance
• Size with string and
measuring tape
• Put one in corn syrup
and other in water
• Weigh and measure
again
PURPOSE

3. Corn syrup egg
I think the egg would
look…
• Weight : Heavy
• Look : different
• Size : Bigger
Water Egg
I think the egg would
look…
• Weight : Heavy
• Look : wet
• Size : same
HYPOTHESIS

4. We need…
• Eggs
• 2 beakers
• Corn syrup and vinegar
and water
• Balance
• String and measuring
tape
MATERIALS

5. 1- egg at top,
bubbles
Corn syrup egg
Before
W- 71.3
S- 17cm
After
W-44.8
S- 13
2- eggs are
floating, foam
Water Egg
W- 62.2
S-14
W- 77.0
S-18.5
3- foam at top,
more bubbles
Observations
• Corn syrup egg at top and
had bubbles
• Floating, more bubbles
and foam
• Foam at top and more
bubbles

6. Conclusion
• The water egg got bigger
because the water had
high concentration and
went to the egg that had
low concentration.
• The corn syrup egg got
smaller because the corn
syrup had less
concentration, so the
high concentration from
the egg went to the corn
syrup.

7. CORN SYRUP EGG HYPOTHESIS
• Hypothesis: wrong
• Size: smaller
• Concentration: less
• My hypothesis was wrong because I thought the corn
syrup had more concentration than the egg.

8. WATER EGG HYPOTHESIS
• Hypothesis: wrong
• Size: Bigger
• Concentration: High
• My hypothesis was wrong because I thought the egg
had more concentration than the water
