Conduct this experiment the shell must be removed. To remove the shell place the two eggs in a jar of vinegar large enough to cover the two eggs with the liquid. Allow standing for three days. Because the inner semipermeable membrane is fragile, take care not to puncture or tear the membrane when moving the eggs.
Place each egg in a clear glass. Cover the first egg in water. Cover the second egg in corn syrup. Allow the eggs to sit in the solutions for 8 hours.
- What is your null hypothesis?
- What is your alternative hypothesis?
- Explain your alternative hypothesis.
- Which solution is hypertonic and which is hypotonic? Explain.5
- Measure each egg and record the results.
- Explain the results.
- Which egg shows the greatest change? Why?
- Now reverse the process. Place the egg that was originally in the water into a glass with corn syrup and place the egg that was in the corn syrup into a glass with water. Let stand for 8 hours. Measure each egg and record the results.
- Using key terms from this lesson, describe your results
- Which egg shows the greatest change?
- Use key terms from Activity 1 to explain the difference between the responses of the two eggs.
