Nature of Science and Scientific Methods Flashcards
methodical observation and experimentation of the structure and behavior
of the natural and physical world.
Science
is a search to use the scientific method to discover an answer to a
question.
Scientific Investigation
What are the Nature Of Science?
Trial and Error Science as a product Science as a process Science as a Way of thinking Science in community
it is the most fundamental talent in science, and it is accomplished via the use
of our five senses.
Observing
is the process of formulating a statement that goes beyond the facts and seeks to
interpret or explain a set of observations.
Inferring
is done by comparing an object to a standard unit.
Measuring
is a talent that is used in the study of identifying similarities and differences as
well as interrelationships and putting things together to achieve a goal.
Classifying
is a talent that allows people to share ideas via talking and listening,
drawing and labeling drawings, drawing and labeling graphs, and acting out scenarios.
Communicating
is the process of projecting them based on a pattern of evidence.
Predicting
What are the 6 basic Science Process Skills?
Observing, Inferring, Measuring, Classifying, Communicating and Predicting.
What are the 6 Integrated Science Process Skills?
Identifying and Controlling variables, Defining operationally, Formulating a hypothesis, Interpreting data, Experimenting and Formulating a model.
defining the variables that might influence an
experiment’s outcome and changing just one element at a time while the other
components are maintained constant.
Identifying and Controlling variables
it is is describing what is done and seen in order to come up with a
definition.
Defining Operationally
is the process of making an educated guess or suggesting a solution
based on evidence that can be tested through an experiment.
Formulating a Hypothesis
is the process of evaluating and making meaning of the findings of an
inquiry.
Interpreting Data
to see if its hypothesis is correct or not.
Experimenting
such as a computer model, a drawing, an analogy, or an equation,
involves generating a mental or physical representation of a process or occurrence.
Formulating a Model
is a method for answering questions about the world around us that
is logical and rational.
Scientific Method
What are the steps in Scientific Method?
Make an Observation, Ask a question, Make a Hypothesis, Conduct an Experiment, Draw Conclusions and Report your Results.
reseach your topic of interest.
Make an Observation
it either accepts or rejects the hypothesis.
Draw Conclusions
develop a question or problem about your topic.
Ask a Question
be prepared to present the project to an audience.
Report your Results
develop and follow a procedure and the outcome must
be measurable.
Conduct an Experiment
predict a possible answer to the problem or questions.
Make a Hypothesis
a form of matter with a specific
composition and set of
characteristics.
Pure Substances
it is made up of only one kind of atom
Elements
educated guess, requires careful thinking and the application of skills.
Hypothesis
a table that lists the chemical
elements that can be produced
in the laboratory and are found
in nature.
Periodic Table of Elements
How many elements are in the Periodic Table?
118 Elements
The rows on the Periodic Table is called?
Periods or Series
The columns on the Periodic Table is called?
Groups or Families
is the lightest element in the periodic
table.
Hydrogen
The number of protons in an atom’s nucleus.
Atomic Number
The arrangement of electrons in energy levels
surrounding an atomic nucleus.
Electron Configuration
refers to the average mass of an
element’s atoms, which is generally stated in
comparison to the atomic mass of carbon 12.

Metalloids
a material made up of two or three
elements’ atoms. It is divided into
acids, bases, and salts.
Compound
are derived from the Latin word acidus, which means "to be sour," they change the color of litmus paper from blue to red.
Acid
are chemical substances that are soapy to the touch in solution and undergo a red-to-blue reaction when exposed to light.
Base
Indicator, used to
monitor the response of the
material in order to determine
what happened.
Litmus Paper
are formed when acids and
bases react with one another and
neutralize each other.
Salt
