Tools and Procedures in Science
The procedures used in science are called the scientific method
Scientific Method
(In Flow Chart Format)
These procedures involve thoroughly examining events and items in nature, finding patterns, and drawing logical conclusions based on verifiable evidence

Tools and Procedures in Science
The procedures used in science are called the scientific method
Step 1: Make Observations
Step 2: Ask A Question
Step 3: Form A Hypothesis
Step 4: Test The Hypothesis
By doing experiments
Step 5: Analyze The Results
Step 6: Draw Conclusions
Step 7: Communicate results
Scientific Method
(In List Format)
A key procedure is when test your hypothesis by doing detailed and thorough experiments (step 4 shown above)

3. Notes SPI 0807.Inq.2 (Tools and Procedures Experiments
Experiments
In an experiment you measure a quantities and/or qualities
In an experiment you should conduct multiple trials
Experiments should include independent variables, dependent variables, constants, and controls.
Example:
Scientists could be testing a new vaccine for the flu virus to determine how effective it is
Scientists could be measuring how air pollution damages plants and animals
Scientists could be measuring the output of solar flares to determine how they might damage our communication satellites

4. (Variables and Controls)
Experiments
SPI 0807.Inq.1
(Variables and Controls)
Notes 
In an experiment…
…you should only test for ONE key thing at a time
This is called the…
Independent Variable
…after you introduce the independent variable, you observe what happens.
This response/result is called the…
Dependent Variable
Items or events that are repeated exactly the same way each time you duplicate an experiment are called…
Constants
NOTE: You should also conduct a control experiment where you either eliminate out the independent variable or use a neutral independent variable (called a placebo)
