The Scientific Method Flashcards
What is the scientific method?
The scientific method shows the way most scientists work, starting from observation to hypothesis testing.
What do scientists do first when they encounter something they don’t understand?
Scientists start by observing something they don’t understand.
What is a hypothesis?
A hypothesis is a possible explanation for what scientists have observed.
What is the next step after forming a hypothesis?
The next step is to test whether the hypothesis might be right or not by making predictions and gathering evidence.
What happens if evidence from experiments supports a prediction?
If evidence supports a prediction, scientists are a step closer to determining if the hypothesis is true.
How do scientists share their findings?
Scientists share their findings in peer-reviewed journals or at conferences.
What is peer review?
Peer review is when other scientists check results and scientific explanations to ensure they are scientifically valid.
What happens if a hypothesis is supported by all experiments?
If all evidence supports a hypothesis, it may be accepted as a theory, but it is not considered indisputable fact.
What are theories?
Theories are accepted hypotheses that have survived extensive testing over the years.
What happens if new evidence contradicts an existing theory?
If new evidence cannot be explained by the existing theory, the hypothesizing and testing process may start over.
What is a representational model?
A representational model is a simplified description or picture of real-life processes used to explain observations and make predictions.
What is an example of a representational model?
The lock and key model of enzyme action is a simplified way of showing how enzymes work.
What are computational models?
Computational models use computers to simulate complex real-life processes, like climate change.
What are some limitations of models?
All models have limitations on what they can explain or predict, such as difficulties in accounting for all variables in climate change.
