Cellular Respiration
Welcome to the "Energized Inquiry" Lab!
Explore how organisms obtain and use energy to sustain life. Follow the instructions at each station carefully, and be prepared to share your findings during discussions and reflections.
Rotate stations promptly when time is called. Ask your teacher if you need clarification or help at any station. Have fun exploring life's power sources!
Learning Objectives
- Compare and contrast photosynthesis, cellular respiration, and chemosynthesis.
- Investigate carbon dioxide's role in cellular respiration through hands-on experimentation.
- Critically evaluate scientific claims related to biological processes.
