Have your plaque displayed
Have something to write with
If you have your signed safety contract...have it out too
Please have a smile on and a great attitude in your head

Objective & Key Questions
Graded work
Remember “

4. Safety Test & Student survey
Complete Safety Test & Turn In
Then, pick up Student Survey Sheet
Complete & Turn In
You have 20 minutes to complete both

5. What is Science?
Experimental Design

6. Thinking Like a Scientist:
Steps & Process
Posing a Question
Making Observations & Inferences
Developing a Hypothesis
Design the Experiment
Collect Data
Interpreting the Data Collected
Drawing Conclusions
Communicating the Data

7. Step 1. Posing a Question Scientist want to know the answer
Scientific Inquiry
Posing a Question
Scientist want to know
the answer
to a question

8. Step 2. Making Observations
& Inferences
Observations:
Using your
5 Senses to
Gather Information
1. Sight
2. Hearing
3. Touch
4. Smell
5. Taste
Inferences:
Interpretations
or Assumption
based on your
observations

9. A possible explanation to answer your question that is testable
Step 3. Developing a
Hypothesis
A possible explanation
to answer your question
that is testable
Usually an
“If, then” statement

10. Step #4 Design the Experiment
Control/Constant – what part of the experiment remains the same throughout
Manipulating Variable -what the scientist changes in the experiment (independent variable)
Responding Variable- what changes because of what the scientist changed (dependent variable)

11. Step 5. Collect Data Qualitative: Judgment Data Ex. Color, odor, sound
Information gathered that can be Opinion or Fact
Quantitative:
Fact that can be
Measured like
Numbers or
Measurements
Ex. Speed & Size
Qualitative:
Judgment Data
Ex. Color, odor,
sound

12. What does the Data Collected Mean
Step 6.
Interpreting the
Data Collected
What does the Data Collected Mean
Uses Tables & Graphs

13. This is where a scientist
Step 7.
Drawing Conclusions
This is where a scientist
states whether the
hypothesis
was correct.
It can be:
Right or
Wrong

14. Communicating the Data
Step 8.
Communicating the Data
A scientist needs to tell,
or communicate,
the results of the experimentt
This is usually a summary of the
Experiment or
Scientific Inquiry Process

15. Now…it’s your turn
