BACTERIA

PROBLEM

• Where do you think you will find the highest amount of bacteria?

HYPOTHESIS

• Our hypothesis is that we were going to find the most bacteria on Mr. Klosses head.
• Because he is bald and more bacteria collects.

MATERIALS

• 2 Q-tips and a plastic bag
• 1 petri dish and with agar and masking tape
• Sharpie and a pencil
• Warm place
• 2 index cards with sample locations

VARIABLES

• Constant- petri dish, the agar, and the q-tips
• Independent-the location
• Dependent- amount of bacteria

OBSERVE, MEASURE, RECORD

• There are 27 colonies growing
• Most of them are cloudy white but there are a few yellow and orange

ANALYZE

• Most of the bacteria was on the faucet.
• Then there was a little bit less than the faucet on Mr. Klosses head.
• The 3rd most was on the locker knob.
• The least was on the button to call the office.

CONCLUDE

• Our hypothesis was wrong.
• Because Mr. Kloss's head did not have the most bacteria.
