1. The Methods of Science
Standard I-1: The Student will understand concepts dealing with the nature of science.
Objective 1: Analyze the methods of science used to identify and solve problems.

2. 7 Steps of the Scientific Method
Observation
Ask a question
Form a hypothesis (educated guess)
Test your hypothesis
Collect data
Draw a conclusion
Make a prediction

3. Hypothesis A hypothesis is an educated guess.
A hypothesis describes what you think will happen.
A hypothesis normally begins with the words I think, feel, or believe.
It can also be written as an if then statement.

4. 3 Parts of an Experiment
Control
Variable
Experimental Group

5. 3 Parts of an Experiment
Control- the part of the experiment that does not change or cause a change and can be used as a standard of comparison.
Variable- the part of the experiment that can change or cause a change.
Experimental Group- the part of the experiment that is being tested.

6. 2 Types of Variables
Independent- the variable that is chosen by the experimenter. This variable is located on the x-axis and will not change unless the experimenter decides to change it.
Dependent Variable- depends on the independent variable and is found on the y-axis.

7. Common Laboratory Equipment
Graduated Cylinder-is used to measure small volumes in cubic centimeters.
Triple Balance-is used to measure mass.
Bunsen Burner- used in the laboratory to heat water and other materials and substances.
Beaker- used to measure volume.

8. Common Laboratory Equipment
Flask- used to measure volume.
Thermometer-used to measure temperature usually in degrees Celsius in the laboratory.

9. Measurements
Meters are used to measure distance or length. Ex. Kilometer, centimeters, hectometers.
Ex. a. The thickness of a dime would be measured in millimeters.
b. The length of your finger would be measured in centimeters.
c. The length of a lab table would be measured in meters.
Liters are used to measure liquid volumes.
Grams are used to measure mass.

10. 3 Types of Graphs
Bar Graphs are used to show quick and easy information.
The circle/pie graph is used to show percentages.
The line graph is used to show changes over a period of time.
