hypothesis
scientific method
technology
2
The step of the scientific method in which you determine what was learned from your investigation
drawing a conclusion
testing the hypothesis
stating the question
forming a hypothesis
3

quantitative
10
Science
covers 3 areas, dealing with the sudy of Earth, life, and matter & energy
begins with observation & asking questions
is a way of investigating & learning about the natural world

conclusions
18
Applying what is learned through science to solve specific problems & come up with practical uses to improve our lives
technology
graphs
models
experiments
19
A data table is used to
allow an experimenter & others to easily analyze information
clearly show any relationship between the independent & dependent variable
record & display data in an organized way
all of these
20
You test this by carrying out an experiment
conclusion
hypothesis
observation
data
21

True
False
22
An effective conclusion should include
all of these
a summary of the experiment's findings
an explanation of any problems encountered during the experiment
whether the hypothesis was supported by the data or not
23
If your experiment does not support your hypothesis the experiment was a failure
True
False
