Title: Cell Transport Hands-On Lab Report
Objective(s): measure how cells are affected by the movement of water.
Hypothesis: The egg will grow in size
Variables:
Time
Egg
Water
Vinegar
Materials:
Raw egg
String or thread or yarn
Ruler
White vinegar
Tap water
Syrup
Jar with lid (like a mayonnaise jar or something big enough to put the egg in)
Procedures:
1. Before beginning the experiment, record at least two observations of the raw egg in your
lab report.
2. Wrap the string around the center of the egg to determine its initial circumference.
Measure the string and record the initial circumference in centimeters (cm).
3. Gently place the egg in the jar and completely cover the egg with vinegar. Use the lid to
seal the jar and note the time. This will be considered the "start time" of the experiment.
4. After approximately 24 hours from the start time, carefully remove the egg from the jar of
vinegar. If the shell has completely dissolved, exposing the inner membrane, move on to
the next step. If not, return the egg to the vinegar until the shell has completely
dissolved.
5. Record at least two observations of the egg.
6. Measure and record the circumference of the egg, being sure to measure it in the same
way every time you measure circumference.
7. Pour out the vinegar and rinse the jar. Then fill the jar about half full of tap water.
8. Gently place the egg back into the jar, making sure it is completely covered with water.
Use the lid to seal the jar.
9. After a total of 48 hours from the start time, carefully remove the egg from the jar of
water.

10. Make two observations of the raw egg, and measure and record the circumference.
11. Gently place the egg back into the jar, making sure it is completely covered with water.
Use the lid to seal the jar.
12. After a total of 72 hours from the start time, carefully remove the egg from the jar of
water.
13. Make two observations of the raw egg, and measure and record the circumference.
14. Complete the data and conclusion sections of the lab. Then complete the "refining the
experiment" section.
Data and Observations:
Record your observations from the experiment in either the hands-on lab or the teacher-led
video. Don't forget to include at least two detailed observations and the measurement of the
egg's circumference in centimeters.
