STEP-BY-STEP DIRECTIONS
1. Gather materials
2. Decide locations to
conduct experiment
3. Measure temperature
in
each location
4. Cut bread in identical sizes
5. Place bread in 5 different zip-lock
baggies.
6. Label each zip-lock baggie for
locations and t

Variables
My independent variable is the temperature in
place.
My responding variable is how much mold grows.
My controlled variable is that all the bread is
homemade and it is non-preservative. Also there is
no direct light. All the bread is the exact sa

PURPOSE
MATERIALS
My purpose is to find
out how the
temperature affects
the time it takes for
mold to grow on bread.
HYPOTHESIS
Hypothesis 1: If the temperature
is very hot it will inhibit the growth
of mold.
Hypothesis 2: If the
temperature is too cold i
