Cellular Respiration—Inquiry Lab Kit for AP® Biology

Product Details

Big Idea 2, Investigation 6, Science Practices 1, 2, 3, 6, 7. Plants create oxygen as a waste product of photosynthesis, but do they require oxygen to live? Does respiration occur in germinating seeds? Students will answer these questions in this Flinn Advanced Inquiry Lab. The Advanced Inquiry Lab begins with a Baseline Activity that instructs students to measure the amount of oxygen consumed by germinating mung bean seeds and control seeds. By recording and measuring any changes, students are able to calculate the respiration rate of those seedlings under specific conditions. These observations and data provide the basis for the Opportunities for Inquiry section of the lab. Questions such as, “Does the amount of time from the start of germination affect the respiration rate?” and “What environmental factors may affect respiration rate?” help to guide and inspire students to develop a testable hypothesis and then design an experiment that they can plan, discuss, evaluate, execute, and finally justify to their peers. Includes detailed teacher notes, reproducible student handouts, two additional types of seeds, and enough materials for eight groups of students to complete the Baseline Activity and prepare for the inquiry activity. A hot glue gun is required and available separately.
