KS4: Useful Microbes
In this lesson plan, students use the story of insulin to learn how microbes can be useful.

All students will:
- Understand that some microbes can keep us healthy
- Understand that some microbes can be put to good use
- Understand that we need bacterial colonisation to live a healthy life
- Understand that we need to protect our normal microbial flora
- Begin to explore scientific research
Most students will:
- Understand that microbes are important in decomposition and nutrient recycling
One of the main ways in which bacteria are beneficial is in the food industry. The natural by-products created during normal microbial growth can be used to make many of the food products we eat.
Fermentation is a process by which bacteria break down complex sugars into simple compounds like carbon dioxide and alcohol. There are different types of fermentation - acetic acid fermentation produces vinegar and lactic acid fermentation produces yoghurt and cheese.
In this lesson plan, students explore how microbes can be useful in industries. They look at some of the most useful microbes and identify their properties and uses in industries such as the pharmaceutical and food industry.
