1. GOALS OF SCIENCE I_________ and un__________ nature
E_________ events in _________.
Use ___________________ to make useful ___________________.

2. The Scientific Method
There are FIVE main steps to the scientific method:
Stating the P_____________ (from an observation)
Forming a H_______________ ( hint: ?)
Setting up a _________ ____________
R__________ and analyz____the results
Drawing c____________

3. STATING THE PROBLEM
This can be in the form of a question or statement.
Implies that an observation has been made to lead to a question…
Science is based on experimentation and observation
Observations can be:
Made directly with your senses
Color
Taste
Shape
Feel
Smell

4. INFERENCES
In contrast to observations, which are things that we see or measure, inferences are c__________ based only on o___________
The rule of inferring is to be __________ (makes sense).
They are always tentative, meaning, they are not final explanations
______ ______ __________ when new information is gained, or observations are made

5. FORMING A HYPOTHESIS
A “t_________” statement, a possible explanation that explains known facts and predicts ________ ________.
Should be written in the form
“If... then…”
Cause and Effect
Why? Or How?

6. DESIGNING AN EXPERIMENT
Must have several things:
V______________
E__________________ Group(s)
receives all of the conditions of the experiment
Independent Variable – one thing that is changed
Dependent Variable – measures how the result respond to the independent variable (how it reacts…)
C__________________ Group
receives all of the conditions of the experiment. The Control group does not get the independent variable (changed condition)
used as a means for comparison in the experiment
CONSTANTS (things that ______ ______ change)
Factors in the experiment that are maintained throughout the experiment, they ___________ the __________ throughout
PROCEDURE
Must be clear and detailed

7. RECORDING & ANALYZING DATA
RECORDING DATA
Numerber data should be g_________ and/or tabled
Observations should be written in clear, c_________ sentences.
TWO TYPES OF DATA
Qualitative – descriptive; a behavior or appearance
Quantitative – numerical data
Data Table
Independent variable (unit)
Dependent variable (unit)

8. RECORDING & ANALYZING DATA
Attempt to figure out what the collected data means… why did it happen as it did?
Graph
Title: Dependent variable vs. Independent variable
D _________ variable (unit)
I____________ variable (unit)

9. Graphing Graph A visual display of information or data
Three main types
_________ GRAPH

10. Line Graph Shows how data _____________________ or shows basic trends
Plotting data
Independent variable = __-axis (h________ or below)
Dependent variable = ___-axis (along the ____ or vertical side)

11. Bar Graph
Compares ___________ collected by ___________

12. Pie Graph
Shows how something is broken down into ________ or ______________

13. FORM CONCLUSIONS
Be sure to draw conclusions based ____________________.
Make inferences based on _____ ______ and the new knowledge gained in the experiment.
_____ ______ restate the procedure or simply restate the results…
How do the results compare to your hypothesis?
How can this data be used further?
What other tests could be done?

14. Self Assesment
1) Directions: Place the Scientific Method Steps in the right order. Use the numbers 1 through 5 to show which steps come first
Recording and Analyzing Results (Graphs)
Design a controlled Experiment (Variables)
Stating the Problem (from an observation)
Conclusion
Form a Hypothesis

15. Self Assessment cont. Designing an Experiment:
What is a controlled group?
How is the controlled group different from the experimental group?
List one thing that you DO NOT do in the conclusion. _____________________
