Ward's® AP Biology Investigation 5: Cell Processes: Photosynthesis

Meets AP Science Practices 1, 2, 3, 6, and 7

• Updated illustrated instructions aid comprehension
• Leaf pigment separation and environmental effects on photosynthetic oxygen production is quantified
• Available for individual student use or class-size kit

In this investigation, the ability of plants to capture, store, and use energy from light for growth and reproduction is brought to life as students practice basic paper chromatography techniques to visualize pigments present in various plant leaves. Using a floating disk assay, students will investigate the environmental elements that affect the rate of photosynthesis under controlled conditions.

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.
