In this Science Buddies science project, you will test several disinfectants to see which ones work best to decontaminate the surface of a cutting board. You can customize this kit to include the nutrient agar plates, cotton balls, dissecting forceps, and other supplies needed to complete this experiment.

Before beginning this project check the rules of your science fair as many science fairs prohibit the use of microorganisms that are not identified to species. Do NOT use this experiment if those rules exist in your science fair.

Germs are everywhere! We try and clean our home with disinfectants, but do we really get rid of all the germs? Find out with this "hands-on" experiment.

Before beginning this project check the rules of your science fair as many science fairs prohibit the use of microorganisms that are not identified to species. Do NOT use this experiment if those rules exist in your science fair.

Rated 5 out of 5 by from Great forceps I purchased the straight edge forceps for my daughter's H.S. science project. She had to put small disks onto a plate with agar. They worked well for her and were easy to hold and control.

Rated 5 out of 5 by from Great for science fair Ordered these for son's 8th grade science fair project. Arrived exactly at time promised. Stored in refrigerator until ready to use. Plate inoculation was easy. Incubated in basement. Grew beautiful (actually disgusting!) specimens in a few days. Son was amazed and fascinated. Science fair conquered!!

Rated 4 out of 5 by from Easy to use and perfect for student micro projects Trying to teach students the proper method for making agar dishes can be difficult. At times when they make their own the agar is lumpy and uneven, making it difficult to observe. The only suggestion I would make is order more than you need because the plastic on the dishes is fairly thin and on every purchase I have made, typically at least one dish is cracked and cannot be used. Other than that these are so much easier than preparing your own.

Rated 4 out of 5 by from Practical but some plates were damaged. I used these plates for my after school program. They worked very well. Just a couple of things to keep in mind if you are considering buying it. 1) the only option of shipping is 2-day, so that will add up to your total. 2) out of the 3 packs I used, 3 plates were unusable: one had a crack, one had some unidentified object in the agar, and one was contaminated. However, overall is a good product.

Rated 5 out of 5 by from Agar plates used in Elementary class Only one of my 120 plates showed contamination. The plates are wrapped in small stacks of ten and double boxed for shipping. No breakage in my order. They are easy to use and store. I appreciate that shipping charges are stated upfront. Several other suppliers offer lower rates per plate cost but ridiculously expensive shipping. I trust Carolina to deliver on time and they did. Used for 5th grade handing washing experiment, Q1 positive control- dirty thumb, Q2 thumb washed with water, Q3 thumb washed with soap & water, Q4 negative control - no treatment. Fabulous results!

Rated 4 out of 5 by from This product was great. When the Petri dishes came, they were soaking wet and had an awful stench to them. However, they worked really well. they came right on time in the mail.

Rated 4 out of 5 by from Easy to use and store The gloves come in a small box which is great for storing large amounts between use but several students have had gloved rip during use which is problematic. However, I'm not sure if the fault lies with the gloved or with the students.

Rated 5 out of 5 by from perfect, convenient, supports lush bacterial growth The plates arrived very quickly. Of 20 plates, one had visible contamination. I contacted the company and a replacement sleeve was shipped immediately at no cost over a holiday! (Fantastic customer service). The plates supported lush, rapid growth of e-coli for a science fair experiment. They were uniformly poured and made the experiment tidy and quick.

Rated 5 out of 5 by from arrived, packaged well I was so anxious to teach again in My school Nursing job, the minute I heard a teacher that was teaching micro, I arranged to pair up and look for dirty things to swab. The auger stood up to their heavy hand and the teaching experience was great for them and I

Rated 3 out of 5 by from Disappointed by how delivered. Overall the product worked, however two of the plates were cracked. Packaging could have been better. I also am disappointed that I paid so much to ship it, had to leave work early so I was home when it arrived so I could get it in the frig, and when I opened it there were no ice packs in the box. More should have been done to keep them cold. Especially when I paid so much to ship it and was told ice should be in it. One set of the agar plates did not work as well as the second set. Could this be because of how it was shipped?

Rated 5 out of 5 by from Perfect for my 6th grader I ordered this for my daughter's science fair project. The pre -poured plates were perfect for her and easy to use. Excellent customer service! Te shipping company made a mistake that Carolina quickly resolved. I will use them for every science need.

Rated 4 out of 5 by from I am using these plates for inducing fungal pigmentation Having an imprint of the plate/media specification- which is your hew addition- is not helping me . HTe imprint on the bottom of the plate is obscuring the pigment formation. Technical data about the culture medium is very helpful, however should be supplied separately. More specifications regarding the medium would be helpful- pH and percentage of elements in it.

Rated 5 out of 5 by from Worked for Me We used them as a QA/QC for a sterile compounding area as well as other areas of our compounding laboratory in the pharmacy in which I work. Agar plate testing is required to ensure there is no growth in our compounding lab as part of USP <797> and PCAB accredidation

Rated 5 out of 5 by from going green Well it just hit me since gas prices are ridiculous and oil companies are spill the oil into the environment its time for things to change I drive a vehicle that runs on flex fuel E85 but I realized there is no place to even buy E85 where I live and I'm being forced to buy-fuel from the very company that is killing out earth home and prices are still rising but still no e85 available but there is Ethanol do the math It is a wise decision to try to stop supporting the Not so green But very rich Oil companies and start supporting the not so rich green options Carolina I choose to start putting my hard earned money and intellect to use !

Rated 5 out of 5 by from Easy to use Bought this 2 years ago from Carolina for my daughters science fair project. Made it easy for her to start her experiments, rather than having to create plates herself. Worked very well for her.... buying another set for my son's science fair experiments.
