Title: using apparatus to know the presence of microorganisms
aims and objectives: description of presence of microorganisms in the air
materials and method: petri dish, agar, distilled water, hand gloves, nose mask, pipette e.t.c
methodology: pipette is used to measure the amount of water in a petri dish and placed outside where hands can not be touched for 24 hours, after then the water is taken to the lab and agar is added for bacteria growth, after 24 hours, if the microbial growth is seen on the cultured plate, then it shows that the air is contaminated with microorganism which mixes with water when exposed to air
precaution: i ensured personal protective equipment are worn throughout the experiment.
conclusion: it is ascertained that air is contaminated with microorganism as a result of the above performed experiment
