EZ BioResearch Bacteria Science Kit


Germs!  They are everywhere!  But, it’s a little hard to explain germs to little children when they can’t see them.  So why not SHOW them?  In a super simple ‘EZ’ bacteria science kit that includes 10 Petri Dishes, you can culture and grow everything from the germs from your mouth to a doorknob in your house to view in your Petri dish.  How about checking out the bacteria that is on your dollar bills?  Ewwww!  It’s fun, gross, and interesting for parents and kids and you get to see them learn how to sterilize, dilute and allow their bacteria to age and grow colonies.  Who knew science could be so fun for a kindergartner?  The best part is, the EZ BioResearch Bacteria Science Kit is inexpensive and has wonderful detailed instructions, all equipment needed to do your research, and even provides a free Science Fair Project E-Book for some wonderful bacteria growing ideas.  Awesome!

The set includes 10 petri dishes that have pre-poured agar (so they are ready to be used) and 10 sterile swabs.  Why is having pre-poured agar important?  Well, in order to culture bacteria (micro-organisms), you must get bacteria -from many sources- and swab it onto the agar which acts as a food.  This set has nutrient agar, so you don’t need to make your own with powder, water, and heating it up.  That is SO convenient and with the nice packaging, everything is ready to be used.  The instructions says to store the dishes (right-side up!) in an area of around 4 degrees Celsius (which is roughly the temperature of your refrigerator) to prevent the water in the agar from evaporating and allow each dish to un-thaw for about an hour before use. Remember, do not FREEZE the dishes because it will damage the agar.  It takes roughly 24-48 hours to see the best results of your experiment and your little scientists can read more about bacteria and how it grows.  This is a great kit and a fun way to look at microorganisms.

1) 10x Pre-poured sterile LB-agar plates (100 x 15 mm Petri Dish)
2) 10x 6-inch sterile cotton swabs (2 per pouch)
3) 1x 0.5 oz hand sanitizer
4) 2 x sterile dilution tubes.
5) 2 x transfer pipets
6) Detailed Instruction
7) Free Science Fair Project E-Book

LB agar plates should be placed in a refrigerator upon arrival. LB-agar plates stored under such conditions have a minimum shelf life of 3 months.


1) Take out one sterile cotton swab. Gently wipe a test area with the cotton swab to pick up bacteria. Here are some of the popular samples of the test objects: human or pet teeth, hands, phone, TV remote, restaurant menu, sink, floor, fruit, vegetable etc.
2) Take out one of the agar plates (No warm-up is needed). Open the agar plate and gently streak the agar plate with the cotton swab to transfer the bacteria onto the surface of the agar plate.
3) Cover the agar plate and place it in an upside-down position in an incubator with a temperature between 85 and 100 oF. A desk lamp or a portable heater can be used as a heat source.
4) Watch appearance of small bacterial colonies on the surface of the agar plates after 12-48 hr of incubation.


LB stands for Luria Broth, a nutritionally rich medium, which is one of the most common media used in the laboratories worldwide.
LB medium is recommended safe for student use, whereas Tryptic Soy Agar medium is NOT suitable for student use due to its selectivity.
