Ward's® AP Biology Investigation 11: Interactions: Transpiration
Educational Materials Biology Educational Materials AP Biology Learning Activities
Meets AP Science Practices 1, 2, 4, 6, and 7

  • Quantitatively measure the transpiration rate
  • The effect of surface area of the leaf is evidenced using two separate activities
In this investigation, students explore factors that affect the rate of transpiration both in the short term of an experiment as well as within evolutionary context. By analyzing stomata density in leaf types and constructing a simple potometer to determine rate of transpiration, students will discover how plants adapt to changing environments to regulate water loss and photosynthesis.

The Only Kits Aligned with AP Science Practices. Ward's AP Biology Investigations provide complete coverage of the Four Big Ideas and Seven Science Practices to help you meet new AP Biology curriculum standards and prepare students for real-world success in college and research-level labs. Each investigation follows a series of three parts, beginning with a structured lab investigation, followed by a related guided inquiry investigation with thoughtful assessment questions, and finally, suggestions to encourage students to formulate their own questions and explore further self-guided experimentation. This complete series of investigations emphasizes the progression to fully student-directed investigations and builds competence in all of the science practices, helping students:
• Practice concept application instead of fact memorization.
• Focus on self-guided experimentation instead of step-by-step lab procedure.
• Investigate real-world concepts with greater curriculum flexibility.
• Apply problem-solving skills to strengthen student inquiry.
