I was pleasantly surprised when my Petri Dishes with Agar and Swabs-Science Fair Project Kit arrived 5 business days after ordering it. It had shipped immediately via UPS and arrived carefully packaged in packing peanuts.
The kit included:
-20 plastic Petri dishes
-20 sterile swabs
-2 (200 ml) bottles of nutrient agar
-Complete instructions on how to do a Science Fair project, how to get the agar prepared and into the plates and a handout on Science Fair display design. VERY complete, very good information.
This is easily the least expensive, most complete set for microbiology experiments I've seen. Just get yourself some distilled water (needed for capturing cultures of bacteria on the swabs) and a microscope if you like, and you'll be 'growing germs' as outlined in the handouts in no time!
NOTE: Do be careful when heating up the agar in the microwave. If you heat it too quickly you will end up with chunky (non melting) agar. Melt it at the lowest setting on the microwave in 30 second increments, swishing it around each time. Be sure to open the cap slightly before heating.
I tried both the hot water bath method of heating (takes forever) and the microwave. I was saddened to make this mistake with the first bottle of agar, but the second batch came out perfect. Take it slow, and all will be well. |
Science Fair went great

| We need petri dishes for a 6th grade science fair project. This was the only set that had enough petri dishes for our needs. The agar solution was fine. Directions were easy to understand and everything worked as expected. |
Great kit, gross bacteria results

This was for my fourth grader's science fair project. The kit came as described. And the directions were easy to follow. We poured distilled water on the sterile swabs immediately before use. My fourth grader had gross bacteria in less than one week!
**It took approx 30 minutes to melt the agar on stovetop. Don't make the mistake of shaking the bottle too hard or you will end up with lots of bubbles. **
Overall, I would definitely buy this kit again. |
Great Science Fair Kit

This kit was great. It arrived on time and intact. The Agar bottles were even came in a Ziploc bag in case they leaked (which they did not). It had very clear instructions and great ideas for presenting your experiment in a science fair exhibit. Preparing the plates was a breeze. When you get the agar it is about the consistency of Jell-O. Heating it up turns it into a liquid so you can pour it into the dishes. I heated them up in a hot water bath as opposed to a microwave and it the agar came out perfect. Flollow the very detailed directions and you will be fine. The kids had fun collecting the samples using the included sterile swabs. Don't swab too hard on the agar though. As long as the swab is contacting the agar you are transferring the sample. If you do it too hard you will gouge the agar and it could come out (that happened with one of our plates). The only other things you need is distlled water which is available in any grocery store and bleach to kill the bacteria in the plates when you are done with the experiment.
A day after swabbing the plates bacteria was growing. You are supposed to keep the plates in a plastic bag to keep the agar from drying out. And man.... when you open those bags, to let them breathe for a few minutes each day, the stink that comes out is nauseating. It is great. The bacteria/mold is growing like crazy.
This is for a fifth grade science fair and my son, who is in second grade, wants to do this when he is old enough for the science fair. I 100% reccomend this product and the seller, Science Stuff, and I will buy it again. |
Excellent product/met my expectations

| The set came with the petri dishes and agar solution. Also included were the instructions which were very easy to follow and also sent some great examples about how to use the product. We're testing animal germs, which was the exact same example they used. My mistake though was trying to pour the agar into the dish before it was completely melted. After putting it in the microwave, the bottle is very hot, but still you have to shake it until the agar is completely liquid or it will come out lumpy. Great product, though. Very good examples for elementary science fair projects. |
