Abstract
Decaying is an important factor in the disposal of organic materials.
The objective of this experiment was to find out how fast apple cores decay under
different circumstances. In order to do this, five apple cores were exposed to five
different environments, such as under a light or outside and observed every day.
The data revealed that the apple core exposed to light all the time decayed at a much
faster rate than the apple cores located outside and an apple core shut off from
receiving light. The apple core did, however, decay at a similar speed to the control
apple core, which was kept at room temperature and open to the air that is used as
oxygen for humans.

Zusammenfassung
Die Faeulnis ist ein wichtiger Faktor beim Abbau organischer Materialien.
Das Ziel dieses Experiments war herauszufinden, wie schnell ein Apfelkerngehaeuse
in verschiedenen Ausgangslagen verfault. Um dieses Ziel erreichen zu koennen,
wurden fuenf Aepfel in fuenf verschiedenen Bedingungen untersucht. Eine
Bedingung war unter einem Licht, zwei andere Aepfelgehaeuse befanden sich im
Freien.
Die Daten haben gezeigt, dass das Kerngehaeuse, das unter einem Licht platziert
war, viel schneller verfault war als die Aefel die im Freien waren und das
Apfelgehaeuse, das kein Tageslicht bekommen hatte. Jedoch ist dieser schnell
verfaulte Apfel aehnlich schnell zersetzt wie das Kerngehaeuse, das als Kontrolle
untersucht wurde. Das Kontroll-Apfelgehaeuse wurde bei Raumtemperatur und in der
Luft, die Menschen ein- und ausatmen, gehalten.

Introduction
The topic for this science project is to find out how apple cores decay the fastest
under different conditions. This topic was chosen because it is a simple way of
showing how quickly foods decompose and how different conditions can affect this.
The materials needed can be found in most households and therefore it could easily
be repeated.
The main focus was how fast these apple cores decay, but their weight also played a
significant role in the observations and results, as there is no way to test if the apple
cores have experienced any forms of decaying.
Decomposition is the process of cells in a core absorbing oxygen and releasing
carbon dioxide. During this process, the apple core is eaten by microorganisms,
which break it up into organic materials, making this a chemical change.
Apple cores decay much faster than the whole apple. The peel around the apple
adds to its protection, but seeing as it was eaten to the core, there is much more
flesh exposed to the air. Therefore, the cells in the core absorb more oxygen and
release more carbon dioxide, adding to the speed of decaying.
Apple cores have fully decayed after about two months. The warmer the air around
the apple core is, the faster it decays.
Mould usually lives on dead organic matter. It needs four things in order to grow:
water, food, suitable air quality and temperature.1 All living organisms require water to
maintain synthesis and chemical reactions in the cells.2

The first step of decomposition is when the flesh left on the apple turns to sugar,
which makes the outsides go brown. Then the sugar decomposes further into organic
materials.
A further sign of decay is when mould forms on the flesh of the apple core. Different
types of mould can be observed in the decaying process of food. Such mould can be
harmful for one’s health if one tries to smell it, because it can harm the respiratory
system. Eating mould is also injurious, but small amounts cannot harm people a lot
as the immune system usually fights off invaders.
Aim
The aim of this experiment was to find out which of the five apple cores tested
decayed the fastest and to be able to show the speed of this. Another goal was to
know how to prevent foods from moulding in households, or how to slow the speed
rate.
Hypothesis
Before the experiment had started, the apple core that was next to the window and
whose jar was open was predicted to decay the fastest out of the five different apple
cores. This prediction was based on the fact that the more oxygen that an apple core
absorbs and lets off, the faster the rate of decay.
Also, the apple core in the jar next to the window was predicted to be the one whose
weight would reduce the quickest due to the same reasons given above.

Method
The materials needed for the experiment are:
- Five apple cores, almost the same size and the same weight
- Five glass jars, which can be sealed properly (three of which will be open,
though)
- Five separate thermometers, all the same model, one in each jar
- Tinfoil to cover jar A and jar D
- Two different desk lights that will be swapped in case of the light bulb for jar B
overheating
- A cardboard box made of five sides with a hole where the light bulb will be
able to shine through
- A blanket to cover the cardboard box
- Two small boxes to stand the desk light on
- Scales to weigh the apples
- Kitchen roll to dry out the different jars
- A camera to take pictures of the apple cores every weekend
Five different apple cores were tested, which were in five separate jars. Each jar was
in a different surrounding. The jars were named from A to E and kept like that for a
month. The five jars were checked every day for the four weeks. Observations were
written down and pictures of the apples were taken every weekend. The temperature
and whether there were fluids (condensation or juice the apple might have expelled
during decaying) in the jar were checked every day. Any signs of decaying were
noted. The weight of each apple core and if the flesh was brown was also written
4
down. Furthermore, a place to write any additional or relevant comments was kept on
the observation sheets.
Jar A was covered everywhere with tinfoil, letting in as little light as possible to the
apple core. The jar was closed at all times, except when I checked the factors stated
above. There was a thermometer checking the temperature in this jar at all times.
Jar B was kept in a cardboard box with a blanket over it. There was a light in the box
shining on the apple core 8-10 hours a day on average. Because of safety
precautions it was not possible to have the light bulb on at all times. The apple was
open to the air we breathe, but the blanket and box presumably made the air muffled
and hot. There also was a thermometer in jar B.
Jar C was always outside, with the jar sealed properly. The fluids inside the jar were
tipped out and it was dried out regularly, trying to prevent these influencing the
decaying of the core. As also in all the other jars, there was a thermometer in this jar.
Jar D was outside as well, but the jar was open. It was on a terrace by the window,
not entirely protected from unwanted influence, such as precipitation or intruding
animals. To ensure extra protection, a lid out of tinfoil, with a lot of holes in it, making
it as similar as possible to when it is open, was made. There was also a thermometer
measuring the temperature in this jar.
Jar E was on the windowsill indoors and open. As all radiators in the house are
located under the windows, the jar on the windowsill was also located directly above
a radiator, although this was not the most desirable location. There was a
thermometer in this jar as well as in all the other jars.

Discussion of Results
The first five graphs show the rate at which the five apple cores lost weight. Figure 6
shows all of the five separate graphs in one graph to show the comparison.
The first thing that catches the eye in figure 6 is of course the weight loss apple B
had experienced. The weight loss happened rapidly, which the steep downward
curve indicates. It can also be seen how the weight stayed almost the same from
days 17-28. The apple core stayed at around five or six grams.
Apple E also catches one’s attention. As the light blue line in figure 6 shows, apple E
had a steady, yet fast weight loss. At about seven grams, the process of losing
weight slowed, as also stated about apple B.
It can be noted that jar C and D, which were both located outdoors, show a similar
weight loss. However, at day 20, apple C continued losing weight, whereas apple D
remained at around 36 grams. Both lost weight significantly slowly.
Up until day 12, apple A reduced weight slowly, but then the weight loss got faster,
even though the process was still a lot slower than the process of jar B and E.
Interpreted from the data, jar E can be clarified as the fastest in decaying. Part of the
hypothesis stated above (turn to page 2) was proven to be right. It was proven that
out of the five apple cores it decayed the fastest, but the weight did not go down the
fastest. Jar B’s weight dropped the fastest at first, but almost stayed the same for
over a week (see figure 2). However, in figure 5 you can note that the weight apple E
lost went down more steadily than apple B (can also be seen in figure 6). Taking this
into account, it can be interpreted that the second part of the hypothesis was
analyzed as wrong. The weight of apple E did not drop the fastest.
12
It is clarified that when an apple with light and warmth has reached about six grams,
it slows down its process of decaying. It is not clear if this happens to all apples.
Discussion- Errors and Modifications
The main error with the experiment was that there was not enough time for all, or
even one of the apple cores to fully decay. If there had been time to complete the
experiment, there would have been more data to work with and find out more about
the rates of decaying.
The size of the apples will have affected how fast they decayed, as they were not the
same size, but same weight. The more or less flesh there is exposed to the air, the
faster or slower the apple core will decay. Unfortunately this was not thought of as a
problem before the experiment was started and only realized near the end of the 28
days.
Furthermore, the scales that were used to weigh the apples were not 100% accurate,
as was also realized after the experiment had already been completed. The scales
may have changed the recordings of the weight of the individual apples and also
influenced the data.
Another problem might have been that the light for jar B was not on the same amount
of time every day, which will have influenced the speed of decaying every day, and
also my data. This was not my error but a safety precaution, and I could not influence
these to have it my way for my experiment.

Conclusions
What can be concluded from this experiment is that light and air getting to apple
cores, and as a prediction to other foods as well, adds to the speed of decaying.
What can also be taken from the data is that by keeping apple cores in a fruit basket,
they will most likely decay faster than when put in the refrigerator.
Based on the experiment, it is possible to interpret that apple cores in warmer
climates decay much faster than in colder climates.
Food that is exposed to a lot of light and warmth decomposes faster, which is a
reason why you put food into the freezer or fridge, where it is kept cool and where
there is no light, except for when you open it.
