time:
16 class periods
active lab time:
220
minutes
objectives:
- Explain how kombucha is made using concepts of metabolic reactions (fermentation), microbial diversity, ecosystems and symbiosis
- Explain how kombucha becomes carbonated (both the actual process and on a particulate-level)
- Use learned concepts to explore kombucha in a way that is personally meaningful and interesting
science concepts:
microbes, fermentation, cycling of matter, ecosystems, gas, pressure
essential questions:
- How is kombucha made and carbonated?
- What occurs as the kombucha ferments and why?
- How can we design an experiment to explore how factors impact the kombucha process and product?
