Bacteria Experiment Kit
Explore the fascinating diversity of bacteria in your own environment! With this kit you'll be able to experiment with bacteria in the air, on surfaces, and even on your hands. You
can also test the antibacterial effects of common household cleaners. This experiment/study kit comes with all the supplies you need for growing your own bacteria cultures. You just provide some common household cleaners.
Want to use this kit for a science fair project? See our experiment ideas below to get you started.
Kit Contents:
- 20 plastic petri dishes
- two 125 ml bottles of nutrient agar
- ethyl alcohol (an antibacterial)
- iodine solution (an antibacterial)
- five 2/packs of sterile swabs
- blotter paper
- disposable bags
- project instructions
Look at Agar & Petri Dishes for individual items.
Science Fair Project Ideas:
- How effective are different types of household cleaners against bacteria
in the kitchen or bathroom?
- Do some natural substances (garlic, tea tree oil) have
antibacterial effects?

I would buy again if needed for another child.  - Wednesday, September 02, 2009 AmazingReviewed By: Stephanie this was great. I am a seventh grade student and i used this kit for my science fiar experiment... i won! i barely did any work and i got the highest grade in the class. BUY THIS PRODUCT!  - Monday, March 02, 2009 Bacteria Experiment KitReviewed By: Meghan Whisenand Wow! This was a fantastic and fun project. The kit made testing all sorts of everyday objects for bacteria a breeze. Contained easy to follow directions and arrived fast. An eye-opener to the importance of good handwashing! Thanks so much  - Thursday, February 19, 2009 Bacteria KitReviewed By: Paula This was a great kit. It had everything needed included in the kit. I agree, there should be 20 swabs included in this kit as well. My kids had a great time and we went nuts swabing everything. I couldn't believe what was growing on my cell phone, the doorknobs, the toilet, etc! Amazing product and great price. Would definitely recommend.
We purchased more swabs so we can do the mouth/mouthwash experiment next :)  - Friday, February 13, 2009 Bacteria Experiment KitReviewed By: Krisha H I purchased this kit for my daughter (6th Grade) to use for her science fair project. The kit was very easy to use and the directions easy to follow. I liked the fact that she was required to prepare the petri dishes before beginning the experiment. This was a great way to introduce her to the world of science. The kit also contained tips and directions about different ways to grow bacteria.

This kit provides everything you need plus instructions for several different experiment ideas. The instruction guide was easy to use. My 7th grade son was able to perform experiments that I did in college. The only negative side is that there are only 10 sterile swabs and 20 petri dishes. We had to buy additional swabs for our experiment.
Overall, I would definitely recommend this product.
- Thursday, January 29, 2009 Bacteria Study Kit Reviewed By: D. Talley I purchased this kit for my daughter to use in conducting a science fair experiment. The kit contained adequate supplies for the project, but the instructions were a little vague on certain things. Overall, the was an excellent kit for the price.
- Tuesday, January 27, 2009 Great for Science Fair Projects Reviewed By: S. Dropping We ordered this kit for our 5th Grade Science Fair project. We grew bacteria from both home and school (washing machine, restroom, keyboard, front door) for our experiment. Never having grown bacteria before, we just followed the instructions that were included in package. It was very simple and we had glorious results, growing all kinds of hairy, green/black/clear colonies.
A must to purchase for your experiments. The cost was reasonable too.
- Saturday, March 15, 2008 Good for a group This is a good kit when you have a group of students. (Otherwise, the price may be prohibitive.) I recommend reading the instructions carefully before determining what you'll do with the kids. The previous reviewer makes some great points.
- Tuesday, February 05, 2008 Bacteria Study Kit This is a very good home science product. My two eleven year old boys were kept busy and interested, learning about agar and petri dishes and the best environment for growing microorganisms. I liked it because the boys were able to independently set up the experiments and evaluate the results.
The bacteria does take several days to grow, so if you are looking for a activity to complete in one day, this is not a good choice. Otherwise, in addition to learning about growing microorganisnms, it indicates where germs are most abundant around the house.
- Tuesday, February 05, 2008 Overall, a very good kit I agree with the previous positive reviews of this kit. My following comments will be more negative, but they are MINOR; I'm mentioning them because they were not mentioned in the previous reviews. But my overall assessment of this kit is definitely positive, and, if I were going to do a group demonstration, I would purchase this kit again.
One thing that I would modify is part of the instructions. It would be nice to have more details about how much iodine, for example, to put on each square of blotter paper, or, if certain substances in the blotter paper sqaures should get separate petri dishes of their own. Example: When we used the blotter paper and iodine, the iodine diffused out of the blotter paper and into the nutrient agar, which was expected. However, it diffused so far out that it killed almost everything else on the plate (petri dish). In other words, we couldn't tell how effective some of the other substances in other blotter squares on the same plate were, because the iodine wiped out almost everything. The same was true of the bleach, although less so. This problem could also be avoided by the use of divided petri dishes and putting one blotter square into each section. I ended up doing this when I redid the experiment.
More discussion in the instructions would also help, although I realize that the objective of this kit does not include functioning as a lab manual. For example, rubbing alcohol (70%) did not inhibit growth as much as we expected, but we don't know if that's because it was relatively ineffective as an antimicrobial or (more likely) if because of its high volatility it simply evaporated too quickly and became ineffective over the three days that we allowed the bacteria to grow at room temperature.
The other minor negative comment I have about the kit is the price. For a co-op demonstration, this is affordable, but the price could put it out of the range of many homeschoolers who might want to do this lab for only on
- Saturday, December 15, 2007 Bacteria Study Kit Reviewed By: Virgil Gibbs I used this kit for the Science Class I teach at the Co-op. This was a fantastic kit and the students really enjoyed culturing different specimens. We watched the cultures grow for a few weeks and it made firm handwashers out of the students!
- Thursday, January 25, 2007 Bacteria study kit This was a very good kit. My initial concern was that there would not be enough agar to fill the dishes. However, after preparing the dishes with a very thin layer (thats all you really need) there was enough to fill some of our own test tubes and do some stabs and still have some left.
This is an excellent intro to general as well as microbiology with or without a microscope though with a microscope a great deal more is possible. In both high school and college microbiology this was the very first project we did, with good reason, and it was the first I did with my homeschool daughters. It is also a very good project with which to introduce children to scientific method as it allows you to not only follow each step in the method but also an opportunity to set up and conduct experiments from start(including preparation of the media)to finish.
There are two suggestions that I will make very strongly. First, without an incubator your cultures will take a long time to grow and if you are unfamiliar with culture prep and care you might be inclined to give up on it too soon.With a bit of creativity we were able to explore various ways to incubate the cultures and compare with non incubated cultures, etc.
Second, be sure to prepare the agar properly or you will get a rough bubbly surface rather than a smooth one.
Forgive my long windedness but microbiology was one of my favorite subjects and this simple kit provides so much for so little cost and time and with some creativity you will never run out of things to do. But also remember that with a project like this you need to use good sanitary practice beyond universal precautions and common sense and when finished dispose of it properly.
