Bacteria around our School 🦠 🧫

 Aim: 

I  want to find out what type of bacteria is are around our school.

Research:




 Method:


Equipment:
  • Cotton Buds 
  • Agar Plates
  • Maker pen
  • Cello tape

Instructions:
  1. Get all of the equipment.
  2. Wash your hands with water and soap.
  3. Use a marker pen to write your name and location on the lid.
  4. Wet the cotton bud  with water and swab the surface. 
  5. Gently swab the agar plate with the cotton bud. 
  6. Put the lid on.
  7. Tape around the edges of the agar plate. 
  8. Keep the agar plate in an incubator overnight.
  9. Observe the plate the next day.
Results:

I don't have my results because I couldn't do it. Because the jelly stuff on the agar plate melted.😤

So here is one of my friends results:

( Credits to Venice)



Bacteria colours:

White = E.coli (poo bacteria)

                        Yellow/gold = Streptococci (throat infection)

         Pink= Salmonella (food poisoning)

       Red= Meningitis (brain infection)

Orange= (worse version of yellow)

Fuzzy/furry=  Food fungus 

Smooth= bacteria


What is on the agar plate?

Venice's plate included fungus, e.coli, orange bacteria, streptococci. When I first looked at Venice's I noticed there was a lot of bacteria. The most disgusting part was the food fungus because it is fuzzy greenish blue bacteria.
