How Tempreture and Light, and Air Affect the Rotting of Food

.

In our society, we have many farmers and families who love to grow and eat natural foods as it has vitamins, proteins, carbohydrates, etc... but many of them struggle in storing it the right way as they don't know the variables that affect the rotting of it, so for that I will do an experiment and research to see what variables mostly affects the rotting of food.

We will be using 3 apples cut in halves, each half will be preserved in a different way, and we will conclude by using our sense of sight, smell, and taste

How does light, temperature, and air affect the rotting of foods?

If we put the halves in different temperatures, conditions, and light exposure, there will be a difference in the level of decomposition.

Independent: Temperature
Dependant: The condition of the apple

Controlled: Apple, container, Temperature, time

Independent: Light

Dependant: The condition of the apple

Controlled: Apple, container, Amount of light, time

Independent: Air

Dependant: The condition of the apple

Controlled: Apple, container, air-exposed, time

Tools: Apple, container, refrigerator, cabinet, knife

Place: House

Steps:

1- Cut 3 apples into halves. Every two halves tested separately by changing one variable.

2- The first two halves: (A1) stored in a container in the dark, (A2) stored in a container exposed to light

The second two halves: (A3) No container in the dark, (A4) No container under the light

The third two halves: (A5) stored in a container in the refrigerator, (A6) stored in the refrigerator without a container

3- Wait for 2 days

4- Conclude the results based on the way it looks, the smell, and the taste every 12 hours until the end of the second day.

ِAs for the results, (A1) was the most affected from the experiment, then (A3), then(A2), Then (A4), then (A5) As it was effected a lot and unbeatable, and the final apple(A6) hasn't changed and is the least affected apple in the experiment

Based on the experiments we made, we can tell that the variable that affects food the most is Air, then temperature, so I recommend families and farmers to store their food in wrapped boxes and place it in a cold place like the refrigerator
