Bacteria Growth Science Fair Projects

Bacteria Growth

Bacteria growth can be impacted by many things. For example, temperature, moisture and food all impact the growth rate of this organism.

Test bacteria on any surface with the Surface Microbes Science Fair Projects Kit: after hand sanitizer, hands, disinfectant.. for example. You can use antibiotics to test the bacteria too.

Anytime you want to test how many bacteria are On Top of a surface like a desk, skin, chicken, computer keyboard, bread dough, a hard piece of chocolate, cheese, inside of an animal's cheek, etc. then use the surface experimenter kit. The kit will let you calculate how many bacteria there are per unit surface area on the object. You can also test for e-coli, however, only the microbe water kit will let you distinguish e. coli from other coliforms and bacteria.

Objectives/Goals

My experiment was to show how much bacterial growth was going to be produced.

Methods/Materials

# Clean Jars
# 4 packets of unflavored gelatin
# One cooking spoon
# One pot or pan
# One tsp. of sugar
# ½ cup water
# Cotton swabs

Results

#Barefoot# only had one moldy spot. #Socks and Shoes# had four or five moldy spots. The jar that was left to check was the one that surprised me the most. #Shoes but No Socks# was covered in mold! Where I had swabbed it, I could see tiny, moldy spots. I could also see about five regular-sized moldy spots. What surprised me the most was something as obvious as a big pink elephant in the room. There was a big, wispy-looking #blob# in one of the corners. It had to be at least half an inch tall (or more).

Conclusions/Discussion

My hypothesis was that #Shoes but No Socks# would produce more sweat and bacterial growth. The other samples had spots ranging from one through five. However, #Shoes but No Socks# had a big, wispy-looking #blob# in one of the corners and also had many, many spots varying in size. Therefore, based on what I saw, I concluded that my hypothesis was supported. 3rd party contributor
