Answer 1

steps to grow bacteria

1

Prepare the agar. Agar is the jelly-like substance used to culture bacteria. It is made from a type of red algae, which provides an ideal growing surface for many different types of bacteria. Some types of agar contain added nutrients (such as sheep's blood) which help to promote more vigorous bacterial growth.


2

Prepare the Petri dishes. Petri dishes are small flat-bottomed containers made of clear glass or plastic. They have two halves - a top and a bottom - which slot into one another. This protects the contents from any unwanted contaminated air, but also allows any gasses produced by the bacteria to escape.

3

Refrigerate the petri dishes until ready to use. If you don't plan on using the agar-filled petri dishes immediately, they should be stored in the refrigerator until you are ready to proceed with the experiment.

4

Record your results. After a couple of days, you will notice an amazing variety of bacteria, molds and fungi growing inside each petri dish.
