Scientific Method Flashcards
✓A scientific inquiry begins with a
problem that can be solved
through scientific investigations.
True or false
all questions are scientific and all problems can be
solved by a scientific method.
False
Why use scientific inquiry
✓It is helpful for scientists to follow certain steps in solving a scientific
problem.
3 types of sci investigation
DESRIPTIVE INVESTIGATIONS
A student placed a plant cell under the microscope to describe its parts.
COMPARATIVE INVESTIGATIONS
A student used hand lens to compare
the size and color of minerals in different rock samples.
EXPERIMENTAL INVESTIGATIONS
A student placed a plant cell under the microscope to describe its parts.
Descriptive
A student used hand lens to compare
the size and color of minerals in different rock samples.
COMPARATIVE
A group of students conducted an experiment to determine what condition is best for the mongo seeds to germinate at the soonest time.
XPERIMENTAL INVESTIGATIONS
Steps in investing
OBSERVATION
• Gathering of qualitative and quantitative data
• Use of senses and instruments for measuring
2. QUESTION
• A scientific inquiry must be objective and can be answered through scientific experimentation
3. PREDICTION
• Hypothesis – a tentative, testable statement or prediction about what has been observed
- EXPERIMENTATION
• Experiment – set of controlled observations that test the hypothesis
• Carefully planned to test one variable at a time - GENERALIZATION
- COMMUNICATION
• Scientific researche

- QUESTION

- PREDICTION
• Hypothesis
set of controlled observations that test the hypothesis
• Carefully planned to test one variable at a time
- EXPERIMENTATION
• Experiment –
– a judgment based on the information obtained during the experiment
• May or may not support the hypothesis
- GENERALIZATION
• Conclusion
• Scientific researches are either published in journals or posted in online sites
• Serve as reference for future scientific studies
- COMMUNICATION
an explanation of a natural phenomenon based on many observations and investigations over time; a hypothesis that is supported by experiments, but may not be true in all conditions
• Theory –
a relationship in nature that is supported by many experiments and is proven to be true in all conditions
Scientific Law –
an investigation where one variable -
the independent
variable is changed
and all other
conditions -
controlled variables
are kept the same
Fair test
• what is measured or observed is
referred to as the
dependent variable
Is changed
Independent variable
The same
Controlled
We will use different types of detergent used for each setup.
Independent
We will observe and compare the quality of cloth after soaking and washing it using different types of detergent.
Dependent
We will use the same type of cloth, same amount of detergent used and the soaking time
Controlled
