Tennessee SPI Objective:
Select tools and procedures needed to conduct a moderately complex experiment.
Essential Questions
1) Which tools and procedures would be best to use when conducting a science experiment? 
2) How do I correctly use common scientific tools such as spring scales, triple-beam balances, metric rulers, calculators, graduated cylinders, stop watches, etc.
Check for Understanding
Identify tools and techniques needed to gather, organize, analyze, and interpret data from a moderately complex scientific
investigation.

2. 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)

3. Scientific Tools In an experiment…
…you measure things with the metric system using tools such as:
…a graduated cylinder
-measures liquid volume
and/or
-the volume of irregular shaped objects
(water displacement method)
-unit of measure:
milliliter (mL), liter (L)

4. Scientific Tools When determining the volume of an object…
…you can use a metric ruler for regular-shaped solid items.
Use this formula: Length x Width x Height
-useful for cubes and/or rectangular prisms

5. 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)

6. 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)

7. 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)

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

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

10. Scientific Tools In an experiment… …you also might use… -beakers
-test tubes
Beakers
Measured in ML
Used to hold substances
Beaker
Test tubes
Test Tubes
No units of measures.
Used to mix, heat, and separate substances..

11. Scientific Tools In an experiment… …you also might use… -goggles
-pipette
Used for eye protection.
No unit of measure
Used to pick up or add small amounts of a substance.
