The purpose of this lab activity is to have students prepare their own bacteria medium for a future bacteria exposure lab. By having students conduct this lab activity, students will learn two main concepts. First students will learn the importance of creating a sterile medium and second what microorganisms need for survival. After creating a pertri dish with nutrient rich agar medium, students will also have the opportunity to reflex on their own lab set up techniques for bacteria growth. This is a simple lab and all the need medium material can be bought at a health food store or regular grocery store. Take a look at my bacteria medium sample PDF to gain a better insight. The original copy is just like the PDF, but without the sample written across it.
