We will have a quiz on this material
tomorrow – Wednesday (9/18)
2.
3. What is a testable question?
• A question that one can find an answer to through
an activity or experiment
The question begins with…
• “How”
• “Can”
• “What”
The question does not begin with “Why”
4. “Why are strawberries so big?”
“How does the amount of rainfall affect the
size of strawberries?”
6. Hypothesis: A proposed answer to a
question based on prior knowledge
“If strawberries receive more than the
average rainfall in a growing season, then
their size will be above average.”
7. A detailed, ordered process that includes
the procedure and materials
Control
• Factor(s) not changed
Control group
• The standard group used for comparison against
the experimental group
8. Variables
• Factors that can be changed
Independent variable
• Factor that the experimenter is manipulating
Dependant variable
• Factor that responds to the independent variable
9. Data
• Detailed information gathered during the
experiment stated clearly without opinion
• 2 types of data
Quantitative – numerical, must include units (metric)
Qualitative – descriptive, using sensory input
• How is data organized?
10. How can data be displayed?
Every graph should include:
• Title that clearly identifies the relationship between
independent and dependant variable
• Labeled axes, including appropriate units
• Consistent and appropriate scale
11. Conclusion – A clear, well-focused analysis
of the question based on the data and
observations collected
12. In a perfect conclusion you will find:
A claim, well supported by relevant data
Important information
Appropriate terminology
More than the obvious or predictable
Details in logical order
Complete, well constructed sentences
No personal pronouns
Facts states clearly without opinion
14. 2 types
• Deductive
The use of a general concept that is applied to a
specific situation
• Inductive
