Safety Standard precautions for handling bacterial cultures.
Project Idea
thumbnail There is nothing quite like the smell of fresh-baked bread to make your mouth water! As any baker can tell you, you cannot bake bread without yeast. Yeast actually eat sugar so that they can reproduce and make more yeast, and make bread dough rise. But can they use sugar substitutes to do this? In this science project you will get to investigate how well yeast grow with sugar substitutes as a food source. Pass the butter, please! Read more

Time Required Average (6-10 days)
Prerequisites None
Material Availability Readily available
Cost Low ($20 - $50)
Safety No issues
Project Idea
thumbnail Crown gall is a plant disease caused by the soil bacterium Agrobacterium tumefaciens. This project uses tomato plants to investigate whether garlic extract can prevent crown gall infection. Read more

+ More Details
- Less Details
Time Required Long (2-4 weeks)
Prerequisites You will need a plant with an existing crown gall infection as a source of bacteria for this project.
Material Availability Readily available
Cost Low ($20 - $50)
Safety Use caution when cutting with sharp knife or razor blade.
Project Idea
Microbes are everywhere in our environment, but for the most part they escape our notice. This project shows you how to safely culture and study common bacteria from your everyday surroundings. Read more
MicroBio_p007
+ More Details
- Less Details
Time Required Long (2-4 weeks)
Material Availability Agar plates must be specially ordered
Cost Low ($20 - $50)
Safety Must follow general safety precautions for handling microorganisms
Project Idea
thumbnail Have you heard that garlic powder is supposed to inhibit the growth of bacteria? Which do you think would make a better disinfectant: a solution of garlic powder or a solution of bleach? This project shows you a straightforward way to compare the effectiveness of different disinfectants (or other antimicrobial agents), by measuring zones of inhibition on a culture plate. Read more
