Bacteria are really, really tiny, but this kit will help your students see common bacteria and fungus and discover just where it is lurking near you. It includes everything you will need to set up your own bacteria farm (you supply the bacteria - don't worry, it's everywhere.)  Discover if hand sanitzers really do kill 99.9% of germs, find out if a dogs mouth is really cleaner than a humans, discover where the most bacteria is in your home or school. This simple kit will give clear and dramatic evidence of bacteria growth - sure to bring out the "Ewwww"s in any group of students (or adults.)

Whats included:

• 20 large (10 cm) plastic petri dishes
• 1 pack of laboratory grade nutrient agar powder, (enough for all the petri dishes)
• 20 extra-long bacteria gathering cotton swabs
• Instructions and activities

Where will we find bacteria?
Bacteria are almost everywhere, and we provide suggestions in our guide for testing many areas for bacteria. It is also a great way to demonstrate the Scientific Method in use.

How long does the Bacteria take to grow?
Under the right conditions, results can be seen in less than a week.

Is growing bacteria dangerous?
This experiment will show the world of common bacteria that is usually hidden from us by actually encouraging it to grow. Once the bacteria grows, the lid should stay on to keep the bacteria in one place.

Petri dishes are sterile. For ages 7 and up with adult supervision.
