Science Buddies: "Ask an Expert"

I need to know how to prepare egar petri dishes, especialy how to heat the egar. Thanks!

I don't believe there is something called "egar" to prepare petri dishes.

However, "agar" is used to grow bacteria on petri plates. Dehydrated nutrient agar is dissolved in water to make a solution and that solution is poured into sterile petri plates (this is just a brief explanation).

This link explains how to work with agar:

Thanks!
