This is an animated PowerPoint presentation that covers section of 6.1 Using Microorganisms of the Edexcel IGCSE Biology course.
The PowerPoint covers the following questions:
How is yeast used in the production of beer? How would you describe a simple experiment to investigate carbon dioxide production by yeast, in different conditions? Can you interpret and label a diagram of an industrial fermenter and explain the need to provide suitable conditions in the fermenter for the growth of microorganisms? What is the role of bacteria (Lactobacillus) in the production of yogurt?
The PowerPoint is designed to directly address each relevant point in the syllabus. It is simple and straight to the point covering the topic in just the right amount of detail.
It's a fantastic resource for both teachers and students or a great tool for revision.
Many of the slides have animations in that will only work when viewed in slideshow mode, so please use that when working through the presentation.
