The purpose of this investigation was to study the effect of temperature on bear activity. This information could be useful in determining the activity patterns of bears due to temperature changes. This might also be beneficial to hikers because it would give them an idea of what weather conditions may cause bears to be active in the area, so that they could take the appropriate precautions. The experimenter’s original hypothesis was that if the temperature drops below 32 degrees Fahrenheit, then bear activity will be significantly decreased because bears hibernate during the winter months when the weather gets colder. The experimenter’s approach for this investigation was to pull data of bear detections through cameras placed throughout the state of Wisconsin and weather records in order to compile sufficient data to analyze and either accept or reject the hypothesis. The data collected indicated that the hypothesis was supported. Bear activity decreased significantly from a minimum of 571 detections when the temperature was above 32 degrees Fahrenheit to a maximum of 26 detections when the temperature was below 32 degrees Fahrenheit. This investigation could help the people of Wisconsin be able to accurately predict when bears may be active based on the temperature in the area. This knowledge could increase the safety of people in places that have higher bear populations. The objective of this experiment was met and the investigation question was answered using the data that was collected.
