SPI 0807.Inq.2 (Tools and Procedures)
Notes Science
A key task is to 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 Procedures in science are called the scientific method
Scientific Method
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
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.
Notes ScienceSPI 0807.Inq.2 Tools and ProceduresTake Notes: just copy down the green text
Ex: Medical researchers might test a new flu virus vaccine tolearn how many people it protects from the flu. (quantity).
Ex: Software designers might measure the “playability” of newPlaystation or X-Box video games (quality).
This is a quantitative/objective measurement.
This is a qualitative/subjective measurement.
Procedures in Experiments
In an experiment……you should only test for ONE key thing at a timeThis is called the…
Key Concepts in 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)
Scientific Tools
…a spring scale
-measures force (weight)
In an experiment……you measure things with the metric system using tools such
as:
-unit of measure:
newtons (N)
Scientific Tools
…a graduated cylinder
-measures liquid volume and/or
-the volume of irregular shaped objects(water displacement method)
In an experiment……you measure things with the metric system using tools such
as:
-unit of measure:
milliliter (mL), liter (L)
Link (1 min 57 sec): How to Read a Graduated Cylinder
Link (3 min 45 sec): Finding the Volume of an Irregular Shaped Object
Scientific Tools
Use this formula: Length x Width x Height
-useful for cubes and/or rectangular prisms
When determining the volume of an object……you can use a metric ruler for regular-shaped solid items.
Link (1 min 7 sec): Calculating Volume of Regular Shapes
…a triple-beam balance
-measures mass
In an experiment…you measure things using tools such as:
-unit of measure:
milligrams (mg) , grams (g) , kilograms (kg)
Link (2 min 25 sec): How to use a Triple-Beam Balance-Video
Scientific Tools
…a metric ruler or meter stick
-measures length
In an experiment…you measure things using tools such as:
-unit of measure:
millimeters (mm) , centimeters (cm), meters (m) , kilometers (km)
Scientific Tools
…a thermometer
-measures temperature
In an experiment…you measure things using tools such as:
-unit of measure:
degrees-Celsius (C) or Kelvins (K)
Scientific Tools
…you would use a microscope
In an experiment…you might need to examine tiny things…
-two types: (1) regular microscopes, (2) electron microscopes
Scientific Tools
…you might need to measure the strength of an acid or base
-you could use a pH indicator
In an experiment…
-unit of measure:
pH scale from 0 to 14
Scientific Tools
…you might use a galvanometer to measure electrical current
-measures both the strength and direction of electrical current
In an experiment…
…to just measure the current you could use an ammeter
Scientific Tools
…you also might use…
-beakers
In an experiment…
flaskTest tubesbeaker
-test tubes -flasks
Scientific Tools
…you also might use…
-hot plates
In an experiment…
-petri dishes -burners
Bunsen burner
Petri dish
hot plate
