6. Steps to investigate why maple trees drop their leaves in autumn are as
follows:
(1) Based on observations, a scientist asks why maple trees drop their leaves.
(2) Based on observations and research of the literature he proposes that
maple trees drop their leaves because of colder temperatures.
(3) To test this explanation, maple trees are grown in two greenhouses
where the only variable is temperature (10C vs. 27C).
(4) Data is collected over time and there is a statistical difference in the
number of leaves dropped at 10C as compared to 27C.
(5) Based on this data analysis, the explanation that maple trees drop their
leaves because of colder temperatures is supported and accepted.,
