Bacteria

R13 grew bacteria from a variety of surfaces around the school. See how we did it and check out our results.

Warning: Do not look if you have just eaten!!


How to swab and grow bacteria:

Materials
Swab
Petri dish
Agar Gel
Sanitiser
Tape

1.  Swab an item using a swab. A swab looks like a cotton bud but longer.

2.  Wipe the swab onto the agar gel that is in the petri dish.

3.  Place the lid on the petri dish and label it using paper tape.

4.  Watch the bacteria grow.

  4. Hi Room 13
    Bacteria is definitely disgusting. I think this is a great way to visually understand the term 'Bacteria'. Your next task might involve minimising bacteria in the school???
    Look at the amount of bacteria that is on the handle of the fountain??? Does it make you think of what you would rather touch? Bacteria is EVERYWHERE!
    Keep up the great work with the experiments...I hope you have plenty of sanitiser in your room!
