Evaluate the following statement and determine whether it is a valid scientific
hypothesis: "Lightning and thunder are caused by angry ghosts."
This is not a valid hypothesis because it cannot be objectively tested.
Your answer
It is not a valid hypothesis because it cannot be used to form predictions.
It is a valid hypothesis.
It is not a valid hypothesis because the subject cannot be observed with a
naked eve.

Transcribed Image Text:Skill 1: Applying The Scientific Method
Science is the pursuit and application of knowledge to understanding of the natural
world by following a systematic methodology based on evidence. The scientific
method is an approach to gaining insights about the way nature works by creating and
testing scientific hypotheses. A hypothesis is a proposed testable explanation of a
natural phenomenon, usually based on prior knowledge and original observations. A
hypothesis forms a basis of predictions regarding properties or behavior of a natural
ei
system under study. Once formulated, the predictions are tested by a carefully
designed experiment, additional observations, or simulations, and the merits of the
hypothesis are evaluated in light of the data. The hypothesis is falsified when data
of
differ from the predictions and, consequently, it is either modified or rejected. The
modified hypothesis is then retested, further modified iteratively, until its predictions
Sys
are consistent with the observed phenomena (Figure 1.1). When the data agree with
the predictions and all the subsequent rigorous tests fail to falsify it, the hypothesis is
accepted as a putative explanation. It is important to recognize that a rejected
hypothesis is not a scientific failure; instead, it is a further step towards understanding
mei
a process being studied as it eliminates a false interpretation and often suggests a
direction for modifying or creating new hypotheses. Multiple corroborating hypotheses
are then used to develop broad general explanations, or scientific theories.
