Question
scientists have been studying ways to increase numbers of new populations of the federally endangered red-cockaded woodpecker. Previous research has shown that the woodpecker prefer to colonize forests with naturally existing nesting holes, rarely moving into new territories with no holes. Scientists wondered if birds would move into new sites if they included trees with artificially constructed nesting cavaties. They hypothesized that birds would colonize these forests with artificially constructed cavaties. Desribe a possible experiment to test the hypothesis, including a control. State a prediction.
Experiment:
Control:
Prediction:
Explanation / Answer
Experiment would involve including trees with artificially constructed nesting cavities. After that observe the behavior of birds for a certain time period. After the selected time period is over compare the results with control and derive the conclusion.
Control: Forests with no nesting cavities
Prediction: Since the scientists hoped for a positive result, control used will act as a positive control and will help in deducing how much percentage of birds colonized trees with nesting cavities compared to trees with no nesting cavities.
