Transcript of Scientific Inquiry

are factors that can change in an experiment. To make an experiment valid, only one variable can change, while the rest stays the .
What is Science?
is a way of learning about the natural world, including the knowledge gained by exploring the natural world.
The Scientific Process
Scientific refers to the diverse ways in which scientists the natural world and propose explanations based on the evidence they gather.
Step by Step
Thinking like a scientist...
Scientists use skills such as, observing, inferring, predicting, classifying, and making models to learn more about the world and make scientific progress.
Observing is to use one or more of your to gather information. Your senses include: sight, hearing, touch, taste, and .
Observations that deal with a
Observations that deal with descriptions that
be expressed in numbers.
Inferring is when you
or the things you observed.
Inferences are not just a wild
. It is based on
reasoning from what you already know.
Predicting means making a
of what will happen in the future based on past experience or .
Predictions are inferences, but for the .
Classifying is the process of
together items that are alike in some way.
Classifying objects and inform-
ation help to stay
so that it could be easily found
and used later.
Making models involves
complex objects or processes.
Models can be
objects, like a globe or TV set; or
they could be generated by a
A model accurately
shows the proportions between
its parts. "Drawn to scale"
DEVELOPING A HYPOTHESIS
DESIGNING AN EXPERIMENT
COLLECTING AND INTERPRETING DATA
Scientific Inquiry often begins with a
problem or about an
These questions come from
and inferences that you make. Perhaps something you saw sparked curiosity.
A is a possible explanation
for a set of observations or answer to a
In science, a hypothesis must be . This means that researchers must be able to carry out the investigations and gather evidence that will either
or the hypothesis.
Once a hypothesis is developed, the next step
is to design an to gather
evidence that supports or disproves the hypothesis.
Before collecting data, it is important to have an
operational definition, which is a statement that
how to measure a variable or define a term.
Data should be recorded in a . Facts, figures, and other evidence gathered through observations are considered .
A conclusion is a of what you have learned from your experiment. This is where it is determined whether or not the data supports or disproves the .
