In the Cellular Respiration Inquiry Lab Solution for AP® Biology, students form and test a hypothesis based on the observations of oxygen consumed by germinating mung bean seeds and control seeds.
Includes access to exclusive FlinnPREP™ digital content to combine the benefits of classroom, laboratory and digital learning. Each blended learning lab solution includes prelab videos about concepts, techniques and procedures, summary videos that relate the experiment to the AP® exam, and standards-based, tested inquiry labs with real sample data. FlinnPREP™ Inquiry Lab Solutions are adaptable to you and how you teach with multiple ways to access and run your AP® labs.

Plants create oxygen as a waste product of photosynthesis, but do they require oxygen to live? Does respiration occur in germinating seeds?
The Inquiry Lab Kit 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 like, “Does the amount of time from the start of germination affect the respiration rate?” and “What environmental factors may affect respiration rate?” help 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. A refill kit for the Cellular Respiration Inquiry Lab Kit is also available (FB2088).
FLINNprep is just one of the powerful learning pathways accessed via PAVO, Flinn’s award-winning gateway to standards-aligned digital science content paired with hands-on learning.
HS-PS1-2. Construct and revise an explanation for the outcome of a simple chemical reaction based on the outermost electron states of atoms, trends in the periodic table, and knowledge of the patterns of chemical properties.
HS-PS1-4. Develop a model to illustrate that the release or absorption of energy from a chemical reaction system depends upon the changes in total bond energy.
HS-PS1-5. Apply scientific principles and evidence to provide an explanation about the effects of changing the temperature or concentration of the reacting particles on the rate at which a reaction occurs.
HS-LS1-3. Plan and conduct an investigation to provide evidence that feedback mechanisms maintain homeostasis.
HS-LS1-7. Use a model to illustrate that cellular respiration is a chemical process whereby the bonds of food molecules and oxygen molecules are broken and the bonds in new compounds are formed, resulting in a net transfer of energy.
HS-PS2-3. Apply scientific and engineering ideas to design, evaluate, and refine a device that minimizes the force on a macroscopic object during a collision.
