Science Method Flashcards
(28 cards)
What is the scientific method?
A process used by scientists to test whether their ideas about how things work are correct.
What is the first step in the scientific method?
Forming a Hypothesis
What is a hypothesis?
An idea or prediction that can be tested.
What are two forms a hypothesis can take?
- A prediction
- A question
Fill in the blank: A hypothesis can be a _______ or a question.
[prediction]
What is the next step after forming a hypothesis?
Testing the Hypothesis
What do scientists do during the testing phase of a hypothesis?
Conduct experiments to test the hypothesis.
True or False: A hypothesis can only be a prediction.
False
What is the first step after suggesting a hypothesis?
Testing the hypothesis through experiments
Testing is crucial to validate the hypothesis.
Name one method scientists might use to test a hypothesis.
- Seeing what happens when a magnet is placed near the rock
- Mixing the rock with vinegar
- Measuring its melting temperature
- Testing if electric currents can flow through it
Each method aims to explore different properties of the rock.
Why is it important to repeat experiments?
To obtain trustworthy results
Repeating experiments helps confirm the reliability of the findings.
What are variables in an experiment?
Certain parts of the experiment that can be changed to see how they affect the results
Changing variables can provide insights into the relationships between different factors.
Fill in the blank: The more often the same result is obtained, the more _______ it is.
trustworthy
What can changing the water temperature in an experiment help to determine?
How it affects the results
Variable manipulation can lead to different outcomes.

What is the first step in the scientific method?
Making a hypothesis
A hypothesis is a proposed explanation for a phenomenon, which can be tested through experiments.
What do scientists do after conducting many tests?
They study all the results to see if they can reach any conclusions
This involves analyzing data to determine if it supports or contradicts the original hypothesis.
What happens if the results do not match the original hypothesis?
The hypothesis must be discarded
For example, if a scientist finds no new elements in a rock, the hypothesis regarding the rock’s composition is rejected.
What occurs if the results support the hypothesis?
Other scientists will repeat the experiment to confirm the findings
This process ensures the reliability and validity of the results.
