Potato Lab
Inquiry investigation:
How can you demonstrate change
in turgor pressure in a plant cell?
• In ISN, record the
following:
• Problem
• Hypothesis
• Procedures (these need
to be detailed)
• Materials
• Data/Observations
• Conclusion
• Possible Materials:
• Distilled water
• Potato slices
• High salt concentration
• Low salt concentration
• Petri Dish

• What was the direction of water movement in
the potatoes (or other chosen plant)?
• What is the independent variable (IV) and
