Whole grain bread molded first, followed by whole meal bread, with white bread molding last. The experiment involved placing slices of three different types of bread - whole grain, whole meal, and white - in separate ziplock bags in a dark place. Observations were made and photos taken daily for six days. On the second day, the first signs of mold appeared as whitish-black spots on the whole grain bread. By the sixth day, all breads showed mold growth in various colors and locations. The conclusion is that whole meal bread molded faster than white bread due to whole wheat flour containing wheat bran shards that provide less protection against mold than refined white flour.

3. What I Wondered Before The
Experiment
I have always seen different kinds of breads in my house ,with an expiry date
and if left they were thrown before the date. How?
I wondered what happens to the bread after the expiry date.
I have decided to experiment with three different breads to check what
happens to them after the date?
Which bread molds faster? ,And why?
I wanted to grow mold because I hadn't ever really seen or been around mold. I
wanted to see what it was like. Also, I wanted to try something new, something I
hadn't really done before
My Hypothesis:
I predict that ,Whole Grain Bread has the higher chances to mold as it is not finely
refined as white bread and it has more Gluten.
Gluten is the protein in wheat that gives bread dough its strength and elasticity,
allowing it to form air pockets and rise.
4. Materials Required And Planning
Materials :
Three zip lock bags
Whole Meal bread
Whole Grain bread
White bread
Journal
Label
Phone Camera
Experiment Goggles
Planning :
Take three different left over breads.
Put each in different zip lock bags
Record and take pictures
Note which bread Molds first
5. Procedure
Create a chart in your journal with the breads.
Place a slice of bread in a bag.
Place the bags, in a dark place where they wont be touched.
Take a photo of each sample on its first day.
Leave the samples overnight.
The next day, note any changes in your science journal, and take another
photo of each sample.
Remember to take careful notes about the mold, like how much mold is
growing, and what colour and shape it is.
After taking your last photos on day six , throw away all your bread samples.

8. According to Wikipedia: Molds are single-celled organisms that group together to form networks of mold.
These colonies act as one organism and release spores that travel in the air to reproduce and form more
colonies. Molds can survive very harsh conditions such as sub-zero temperatures, extreme heat, and
acidic liquids.
According to Madsci.org: Molds eat by squirting liquids into the food and growing hyphae, or roots, into the
partly-digested food to consume it.

9. Conclusion
At the end of the experiment, throw away the sealed bag containing the moldy bread. You
do not want to be around when the bag opens. Inhaling mold spores is harmful.
There are so many interesting kinds of mold in fascinating colors. I quite enjoyed doing this
experiment.
The green stuff on your slice of bread is called mold. Mold is a microscopic, living organism in
the Fungi kingdom, related to yeast and mushrooms. Although it can be harmful if handled
incorrectly, mold is not a bacteria or virus
Whole wheat flour has the shards of bran left in it, which gives the flour the characteristic
darker colour. Since the shards are chemically inert, the white flour will have slightly higher
protein or gluten content that
My Final Observation is that the Whole meal Bread Molds faster in comparison to the other
two.
