Meets AP Science Practices 4, 5, 6, and 7, and Big Idea 4.
- Examine enzyme activity both qualitatively and quantitatively
- Explore the physical factors affecting enzyme activity
- Conceptual illustrations enhance understanding
In this set of investigations, students will estimate the rate of enzyme activity under a variety of experimental conditions to discover methods for executing chemical reactions with greater efficiency. Students use an extract of turnips containing the enzyme peroxidase, which reacts with its substrate (hydrogen peroxide) and a color indicator (guaiacol) resulting in the formation of a product (O₂). Students additionally develop data collection strategies and analyze their results. A refill kit is available and contains only consumable component items it does not contain additional student or teacher guides.
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.
