Scientific Investigation on Bird Nests: Understanding the Impact of Latitude
A. What question is being asked in this investigation?
A. Does the number of eggs in a nest of this bird species vary with the latitude of the area the bird lives in?
B. What is the independent variable?
B. The latitude of the area
C. What is the dependent variable?
C. The number of eggs
D. What is the constant in this study?
D. The species of the bird
E. What is the hypothesis proposed?
E. The number of the bird eggs in a nest in a temperate zone area will be greater than that of a tropical area.
F. What is the sample size in this investigation?
F. 600 nests
G. Is there a repeated measure in this study?
G. The number of eggs in all the nests were counted; therefore, it is the repeated measure.
Explanation:
A. In this investigation, the scientist wanted to see if the number of eggs in a nest varied according to latitude, therefore, the question she will be seeking an answer to is: does the number of eggs in a nest of this bird species vary with the latitude of the area the bird lives in?
B. The independent variable is the latitude of the area
C. The dependent variable is the number of eggs
D. The constant is the species of the bird
E. The hypothesis is that the number of the bird eggs in a nest in a temperate zone area will be greater than that of a tropical area.
F. The sample size is 600 nests
G. The repeated measure is to count the number of eggs in each nest in all 600 nests.
This scientific investigation delves into understanding how the number of eggs in bird nests is affected by the latitude in which the birds live. The independent variable is the latitude, which is controlled and manipulated by the scientist. On the other hand, the number of eggs in the nest is the dependent variable, as it is influenced by the latitude. The constant in this study includes the specific species of bird being examined and the total number of nests studied.
Although not explicitly stated, a hypothesis in this experiment could be formulated as: "The number of eggs in a nest in a temperate zone area will be greater than that in a tropical area for this specific species of bird." The sample size for this investigation encompasses 600 nests, with 300 nests in temperate zones and 300 nests in tropical zones.
The repeated measure in this study involves counting the number of eggs in each nest across all 600 nests, providing valuable data to analyze the impact of latitude on the number of eggs. Understanding these key elements of the investigation is crucial to interpreting the results accurately.
