How to test my high school bathroom for germs?

I want to test various surfaces in my high school restrooms (which are disgusting) for bacteria. I know i will need:
Agar plates
Sterile swabs
and a culture medium

I just don’t know how much it will cost and where to get the supplies. If i missed anything or i am wrong please correct me. Thanks.

This is a classic experiment that a lot of students will do at some point. Look on the internet for a shop in your area that sells scientific supplies. There is a chain of such stores called "the Apothecary Shop" where I live that carries them. Otherwise they can be found on the internet in packs of 20 for less than $10.

What you are looking for are petri dishes that are pre-loaded with agar and then hermetically sealed. I just googled "petri dish" and they immediately came up under the shopping results. Also, someone above me mentioned rubber gloves and that is probably not a bad idea.

The one thing you are missing is an incubator. Without one you will need to leave the petri dishes for several days, but with one you can have cultures in less than 24 hours.

Good luck!

*someone said you will need a microscope and in my experience that is not necessary. The beauty of this experiment is that most of the bacterial colonies will be around a centimeter or more in size and can be seen with the naked eye. I have seen some cultures that grew so large in 24 hours that they stood about a centimeter off of the dish. You would be hard pressed to identify anything with a microscope unless you are looking for something specific.

What is the best steel to use to run a chain hoist 11′ lifting a load of 300# max. 1" 1144 steel rod?


The choice of steel is not as important as the design. Is this a one time lift or are you designing something that will be used constantly 24-7? Will this be outside where rain, snow, dust, etc are a concern? What is the 300 lb load? Is it something that needs to be lifted slowly and steadily?

For the Selective High Entrance Test, we can not bring scrap paper?

For the Selective High Entrance Test (Melbourne High, Mac.Robertson, Nossal High, Suzanne Cory High School), the website said that we can not bring any scrap paper and should use the back of the answer sheets for any working out that are needed.

But what if you don’t have any spaces left? Do you get extra white paper or what?

Thank you for answering.

I can’t remember because it’s been so long since I did it, but if memory serves me correct, then the supervisors will give you some lined paper if you ask for it.
