Cricket Investigation

Question: Does the cricket prefer a light or dark environment?
Hypothesis: If the cricket spends more time in the light then the cricket prefers the light because it is more attracted to it.
Background Research: They are approximately 900 types of crickets. Crickets have good vision and good hearing. Crickets have compound eyes which means that they are able to see in many directions at once. When it comes to chirping crickets chirp more when the temperature is hotter. They chirp by rubbing parts of their body together. When the temperature is 52 Fahrenheit, crickets chirp about 60 times a minute. The reason crickets chirp is to attract female crickets. Only male crickets chirp. Crickets diet consist of fresh fruits, tomatoes, fresh seedlings, fungi, alfalfa, apples, bananas, grapes, and etc.

Explanation: In my data table what I did to collect my data I did 5 trials. I collected data by observing what the crickets were doing in the tank every 15 seconds. If they were walking I would put a tally mark next to it and if it was simply standing I'd put a tally mark next to that and the same thing with jumping. Along with seeing where they were every 15 seconds I wrote down if they were in the light or in the dark.

Conclusion: Based on my data table the cricket liked to spend more time in the light. At first the cricket was just in the tube which is the dark part of the environment it is in. Then it began to jump onto the tube which is considered as the light  part. My data supports my hypothesis because my hypothesis states that the cricket would spend more time in the light because it is attracted to it. When I started recording data the cricket was mostly in the tube but then it spend the rest of the time in the light.
