AIM: to practice using some sterile techniques, to examine a range of micro-organisms found in air macroscopically and to examine a range of micro- organisms found in food and water macroscopically APPARATUS: *<Tab/>Incubator *<Tab/>Sterile nutrient agar plates 1.<Tab/>3 water samples 2.<Tab/>1 air sample 3.<Tab/>3 food samples *<Tab/>Bunsen burner *&…showed first 75 words of 734 total…

Yoghurt contains microbes devoid of any being provided from the air. 14)<Tab/> It is completely essential/ obligatory to use sterile techniques when dealing with bacteria, microbes and micro-organisms to guarantee there is no infectivity from other microbes situated somewhere else. This ensures a higher percentage of accuracy within the results CONCLUSION: We managed to observe sterile techniques while also observing macroscopic microorganisms in food, water and the air
