Mold Lab
By: nick
Will mold grow faster if we add algae and pond scum to a white piece of bread?
If we put pond scum an a piece of bread mold will grow in 4 days.
MATERIALS:
1 pc. of white bread
1 ziploc bag
1sharpie marker
1 plastic knife
1 white label
1 bag of algae and pondscum
Procedure:
Step1: collect all materials
Step2: put bread on desk
Step3: open bag of algae
Step4: spread algae on bread
Step5: place bread in bag
Step6: seal bag
Step7: take bag carefully to teacher
Step8: clean up materials
Observations:
June 2nd, 2003
Control – no mold
Bread with pond scum- no mold on the bread. There is a lot of condensation in the bag. The bread is wet and soggy. You cant see the middle of the bread.
June 6th, 2003
Control- no mold.
Bread with pond scum- there is mold. Mold is on the outside of the algae. The mold is fuzzy and gray.
June 9th,
Control- no mold.
Bread with pond scum- the mold is very fuzzy. It looks wet. The mold is green white and gray.
Conclusion:
My hypothesis was correct. I think it was right because it would take at least 2 days. I also figured it would take less than 5 days, because a regular piec of bread would take at least 5 days.
Mold grows on different surfaces at different rates. Mold is very fuzzy and it is different sizes. There are many different kinds of mold. Mold is different shapes sizes and colors. It can spread different diseases and cause allergic reactions.
If I did this experiment again I would use old cheese. It would grow mold fast because it is old and rotten.
