Tennessee SPI Objective:
Design a simple experimental procedure with an identified control and appropriate variables.
Essential Learning
Students will examine the steps of the scientific method and
key components of experiments to include independent
variables, dependent variables, controls, and constants.
Check for Understanding
Identify tools and techniques needed to gather, organize, analyze, and interpret data collected from a moderately complex scientific investigation.

Tools and Procedures in Science
Procedures in science are called the scientific method
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
A key task is to test your hypothesis by doing detailed and thorough experiments (step 4 shown above)

Procedures in Experiments
In an experiment you…
…measure quantities and/or qualities
…should record in detail everything you do and observe.
…should conduct multiple trials
…should include independent variables, dependent variables, constants, and controls.
Ex: Medical researchers might test a new flu virus vaccine to
learn how many people it protects from the flu. (quantity).
This is a quantitative/objective measurement.
Ex: Software designers might measure the “playability” of new
Playstation or X-Box video games (quality).
This is a qualitative/subjective measurement.

4. Key Concepts in Experiments
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)

5. Scientific Tools In an experiment…
…you measure things with the metric system using tools such as:
…a spring scale
-measures force (weight)
-unit of measure:
newtons (N)

6. -measures liquid volume milliliter (mL), liter (L)
Scientific Tools
In an experiment…
…you measure things with the metric system using tools such as:
…a graduated cylinder
-measures liquid volume
-unit of measure:
milliliter (mL), liter (L)

7. Scientific Tools
In an experiment…you measure things using tools such as:
…a triple-beam balance
-measures mass
-unit of measure:
milligrams (mg) , grams (g) , kilograms (kg)

8. Scientific Tools
In an experiment…you measure things using tools such as:
…a metric ruler or meter stick
-measures length
-unit of measure:
millimeters (mm) , centimeters (cm), meters (m) , kilometers (km)

9. Scientific Tools
In an experiment…you measure things using tools such as:
…a thermometer
-measures temperature
-unit of measure:
degrees-Celsius (C) or Kelvins (K)

10. Scientific Tools
In an experiment…you might need to examine tiny things…
…you would use a microscope
-two types: (1) regular microscopes, (2) electron microscopes

11. -you could use a pH indicator
Scientific Tools
In an experiment…
…you might need to measure the strength of an acid or base
-you could use a pH indicator
-unit of measure:
pH scale from 0 to 14

12. Scientific Tools In an experiment…
…you might use a galvanometer to measure electrical current
-measures both the strength and direction of electrical current
…to just measure the current you could use an ammeter

13. Scientific Tools In an experiment… …you also might use… -beakers
-test tubes
-flasks
beaker
Test tubes
flask

14. Scientific Tools In an experiment… …you also might use… -hot plates
-petri dishes
-burners
hot plate
Bunsen burner
Petri dish
