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
Instructions1) First click on "View" from the top-menu bar.2) Then click on "Slide Show" from the drop-down menu.3) Then use the right-arrow button on your keyboard to advance through this presentation.
Notes
Step 1: Make ObservationsStep 2: Ask A QuestionStep 3: Form A HypothesisStep 4: Test The Hypothesis By doing experimentsStep 5: Analyze The ResultsStep 6: Draw ConclusionsStep 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)
SPI 0807.Inq.2 (Tools and Procedures
Tools and Procedures in Science The procedures used in science are called the scientific method
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
Notes
SPI 0807.Inq.2 (Tools and Procedures
In an experiment……you should only test for ONE key thing at a timeThis is called the…
Notes SPI 0807.Inq.1 (Variables and Controls) Experiments
…after you introduce the independent variable, you observe what happens. This response/result is called the…
Items or events that are repeated exactly the same way each time you duplicate an experiment are called…
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)
In an experiment… …you use scientific tools such as…
Notes
…a triple beam balance …a metric ruler or meter stick
…a graduated cylinder
…a spring scale -measures force (weight)
-measures volume
-measures length
-measures mass
SPI 0807.Inq.2 (Tools and Procedures
…a metric thermometer-measures temperature …a stop watch-measures time
-measures acidity and basicity …a pH indicator
-measures electrical current (strength and direction)
…a galvanometer
Experiments
…a microscope -allows you to observe very small things

SPI 0807.Inq.2 (Tools and Procedures
In an experiment……you measure things with the metric system using tools such as:
-unit of measure: newtons (N)

…a graduated cylinder-measures volume
SPI 0807.Inq.2 (Tools and Procedures
In an experiment……you measure things with the metric system using tools such as:
-unit of measure: liters-examples: milliliter (mL), liter (L)
-can be converted to cubic centimeters etc.-measures both liquid volume and volume of irregular solids
In an experiment……you measure things with the metric system using tools such as:
