Background Information

• Geared for Elementary students in Grades 2-6
  because in all South Carolina State Science
  Standards there is a standard Inquiry standard
  across all grade levels.

Scientific Method

Question

• Does bread mold faster in dark or light
  conditions?
• How does light affect the reproduction of bread
  mold on white bread?" (This question would be
  asked by older students with more terminology)

4

• The bread in the window seal should mold faster
  because it increases the temperature causing mold
  to grow faster. Light penetrates the bag, causing
  the temperature to rise. In the dark location,
  there are no factors to raise the temperature,
  therefore taking it longer to mold.

5
Experiment

• In this experiment, you will take 2 pieces of
  bread and put them in a sealed sandwich bag.
• Place 1 bread sample in a cabinet (a dark place)
  Label this sample 1 with a black marker
• Place the other on a window seal ( a light place)
  Label this sample 2 with a black marker
• Leave the samples in their proper locations for
  5-7 days.

6
Experiment cont.

• Keep a daily log of each sample noting physical
  properties like color changes in the bread and
  possible sweating in the bags.
• Record which one molds first (Sample on window
  seal, or sample in cabinet?)

7
Data Collected

• At the end of the experiment, collected data will
  include the 2 bread samples (or pictures), daily
  logs on both samples, and conclusions/explanation

FLaReS Testing

• F-Falsafiability This is falsifiable because
  another experiment could be to put the bread
  samples in another light/dark location. (For
  example, on a table and in a closet)
• L-Logical It is logical with what we know about
  mold production. Mold grows faster in warm
  conditions because the chemical reaction is
  sensitive to temperatures. So when the
  temperature is warm, mold grows faster.

FLaReS Testing

• R-Replicable This experiment is replicable and
  in fact has been replicated many, many times.
• S-Sufficiency The data would be sufficient
  because the actual mold could be seen on the
  bread sample (either by seeing the actual bread,
  or by pictures) and a daily log is kept on each
  sample noting any changes.
