Transcript of The Growth Of Mold On Strawberries

Hypothesis
My hypothesis is the warmer the temperature that the strawberry is in the faster mold will grow on it. I also think that if more moisture is added to the strawberry although the texture might get more soft and squishy the mold will grow slower.
The Purpose
The Growth Of Mold On Strawberries

The purpose of this experiment is to find
out which temperature will make mold grow
the fastest. Also to find out if more moisture is
added will the rate of growth slow down or
speed up.
Observations
Fridge
Analysis
Looking at all the observation it is obvious that mold grows the quickest when it has more moisture in its environment. It also grows quicker when it is in a warmer environment. These two things relate because the warmer the environment is the more moisture is in the air. This is because mold is a fungi and like all plants it needs water to grow. Mold spores are in the air and once it finds moisture and food which are the two things they need to grow the mold spores latch on and they begin to reproduce very quickly which is why when the mold started to grow it got bigger very fast.


Conclusion
In conclusion my hypothesis was incorrect, yes mold grows on strawberries faster in a place of heat but the more moisture there is in an environment the faster it grows.


Materials
- Strawberries
-Water
-Ziploc baggies
-4 Different controlled temperature (fridge,freezer,outside and room temperature)
-Journal
-Camera
-Writing Utensil
-Thermometer
-Mold scale
-Softness scale
- 1 tbsp measuring cup


Procedure

1, Get 8 strawberries, 8 Ziploc bags, and 4 tbsp of water. Set the water out until it reaches room temperature. Put the 8 strawberries in the 8 different Ziploc baggies and seal four of the bags. Put
one tbsp of water in each of the other four of the bags then seal them.
Setup
Next Steps
Put two bags one with water and one without water in four different locations. One in
the fridge, one in the freezer, one outside and one in a room that you can control the
temperature. Use a thermometer to measure what temperature each location is.
During The Experiment
Everyday at the same time, take picture of your strawberries,record
how much mold has grown on them,record any differences you find and record all
the characteristics of the strawberries (which includes texture,leaves etc). Everyday
write where each strawberry is on the mold scale and on the softness scale. Also every
day you need to record what the high and low temperature is outside because you cannot
keep the temperature consistent like you can in other locations.
