Evviva Sciences Nutrient Agar Petri Dishes Science Project Kit, Pre-Poured Agar Plates for Science Experiments, with Experiment eBook

We ordered these for a Stem fair. We received them and some had stuff already growing, we reached out and they replaced the product with no issues. Had a lot of growth after our swabs as well, so these Petri dishes are definitely a good product to use. The instructions were very simple to understand and you didn't have to do much to get the results.

Anytime a gift giving opportunity arises, my grandson requests these petri dishes. From the culture, to growing bacteria and being able to look at it under the microscope, is a great learning experience for him. He loves to learn and discover new things and the Evviva Sciences Nutrient Agar Petri Dishes is an age appropriate resource that fosters learning plus it's safe to use. I highly recommend this product.

These petri dishes were not sterile as listed in the description. At least 2 were growing visible mold when I attempted to use them.Updated review and rating from 1 to 4 as the seller reached out and sent a full refund. Apology accepted!

Problem. Could not use in lab because mold was already growing on agar dishes.

No contaminated plates in my order. The expiration date is over a year from now, which is much longer than any other petri dishes I've had. I appreciate the information about refrigerating them and "thawing" them for an hour. Pictured with my review is a plate exposed to outside Ohio air for one hour on a calm day (very low wind), taped shut, and then held in a plastic baggie for several days in a dark, warm (70s°F) area.Happy with this product.

This set worked so well, very easy to use, just use the sterile swabs provided and you will grow impressive samples.We swabed the backyard soil, floors, bottom of shoes, sink, toilet seat, fingers and toes and an unwashed apple. The kids were really impressed by the amount of microorganisms grown from an invisible stuff on the swabs.We also bought a microscope and were able to actually see all of the different types of microbes and fungi that grew on these dishes.My kids are 6.5 years old, they are now much more conscious about washing hands, good hygiene and washing food.

Bought for my son’s 7th grade science project. Product is Ok, be aware in order to get results, the Nutrient Agar needs to be in a warm area. It took awhile for us to see results, so plan ahead this is not a project you can do at the last minute. Overall I am satisfied!
