Investigatory Project

Purpose

To determine which type of food will the molds grow the fastest, and to help households decide in which food to consume first.

In which food type will form mold the fastest, rich in Carbohydrates or Vitamin C?

PROBLEM

Hypothesis

I think that if the food is rich in Vitamin C, then the molds will grow faster compared to foods rich in carbohydrates.

Experimental Design

Manipulated variables:

kind of foodResponding Variables:

growth of molds

Controlled Variables: temperature,

container, amount of food,

Materials

1 loaf of bread

¼ kilo peach

6 plastic containers

1 meter plastic cover

Procedure:

1. Cut the bread and peach into pieces. 2. Layer the bread into three separate containers, the

same with the peach. 3. Be sure to cover each container with plastic and label

them.4. Leave the containers untouched in one week. 5. Observe the containers each day. 6. Record observation.

ResultsType of Food

Day 1 Day 2 Day 3 Day 4 Day 5 Day 6 Day 7

Vitamin C(peach)

No effect No effect No effect molds began to appear

Number of Molds increased

Molds covered the fruit

Starting to decay

Carbohydrates(bread)

No effect Few molds are observed

The number of molds increased

The bread was covered with molds

Starting to decay

decayed decayed

Food rich in Vitamin C (peach)

Food rich in carbohydrates (bread)

We therefore conclude that our hypothesis was wrong because the

molds grew faster in the bread which is rich in carbohydrate than

the peach that is rich in Vitamin C.

We also speculated that the households should buy more

Vitamin C rich foods like fruits, and consume immediately foods rich in

carbohydrates such as breads because they are easily damaged.
