Scientific Methods Flashcards
What is Science?
Systematizes body of knowledge based on gathered facts, observation and experimentation.
What are the two ways of process of science?
Science as a product is an ever-changing body of knowledge, and a process of investigating and thinking.
What involves in way of thinking?
Reasoning
What involves in way of investigating?
Questions, observations, experimentations, and predictions.
meaning of the Latin word “scientia”
“having knowledge”
“scientia potentia est”
“knowledge is power”
what is knowledge?
facts, information, and skills acquired by a person through experience or education.
it is the theoretical or practical understanding of a subject.
Steps of scientific method
- obeservation
- question
- hypothesis
- test your hypothesis by doing an experiment
- data collection and analysis
- conclusion
- communicate results
what is the scientific method?
A process that is used to find answers to questions about the world around us.
What is a hypothesis?
It is an educated guess based on observations and your knowledge
of the topic.
What is the core of scientific method?
Hypothesis testing
First step of scientific method and one of the most important tools for a scientist.
observation
What is Scientific observations?
Scientific observations can be made directly with our own senses or may be made indirectly through the use of tools.
Two types of scientific observations.
Quantitative and Qualitative observations
Qualitative observation
When observations are recorded without capturing numeric data values. This type of observation is more subjective and relies on the researcher’s interpretations.
Quantitative observation
Observations are quantitative if they return numerical data. When numeric values are recorded, the observations are more objective and quantifiable.
This type of observation involves using the five senses—sight,
hearing, touch, taste, and smell—to gather information about
the environment or a particular phenomenon.
Observation Based on Senses
It’s a direct way of perceiving the world, often used in qualitative assessments where the details are described without numerical measurements.
This refers to making observations that are influenced by one’s previous knowledge, experiences, or understanding of similar
situations.
Observation from Prior Experience
This type of observation involves using tools or instruments to quantify or measure aspects of the environment or a phenomenon.

What is Inference?
The process of drawing a conclusion or making a logical judgment based on evidence and reasoning rather than direct observation.
In science, inferences are often made after analyzing data or observations to reach conclusions about phenomena that may not be directly observable.
What is scientific theory?
A well-substaniated explanation of a natural phenomena, that includes multiple trials, repeatable results and peer review. Your experiment must be conducted over and over again to ensure its validity.
