Scientific Method
The Goal of Science
Deals only with the
natural world
Collect and organize
information
Propose explanations
that can be tested
Science uses evidence to learn about
the natural world and create a body of
knowledge.
Science begins with observations -
often taking data on what you see,
hear and smell.
DATA is the information gathered from
observations:
Quantitative data = numbers
Gathered by measuring or counting
Qualitative data = descriptive
BOTH kinds of data are important
INFERENCE = a logical interpretation
based on prior knowledge or experience
E.g. You see a broken window and a
baseball on the floor next to the glass - you
infer that a baseball broke the window
HYPOTHESIS = a proposed scientific
explanation
This statement is testable and can be
confirmed with experimentation or further
observation.
PREDICTION = an "if-then" statement that
shows what you expect to see as a result of
an experiment or observation
E.g. If fertilizer makes a plant grow faster,
then seedlings planted with fertilizer will be
taller than those without.
Steps of the Scientific
Method
1. Ask questions, make
observations
2. Gather information
3. Form a hypothesis
4. Set up a controlled
experiment
5. Record and analyze
results
6. Draw a conclusion
7. Repeat!
