If you don’t have Petri dishes, use glass baby food jars with the labels removed. Cover them with foil and sterilize them in the oven along with the beaker.
1 beef bouillon cube 2 teaspoons (8 g) of sugar 1 cup (240 ml) of distilled water 1 packet (2 1/2 teaspoons or 7 g) of unflavored gelatin
If you don’t have a hot plate, put the beaker into the microwave and heat it for 10-second increments until the mixture boils. Ensure that the agar powder or bouillon mixture dissolves completely.
If you don’t have a thermometer to check the temperature, wait about 10 to 15 minutes before using the medium.
Spend a minute washing your hands after you’ve sanitized your space.
For example, you might write the bacteria, the date, and your initials.
Repeat this for each Petri dish that you have.
