TRANSCRIPT
Lab Equipment
• Triple beam balance
• Thermometer
• Metric ruler
• measures mass, metric unit is the gram
• Measures temperature celsius/kelvin
• Measures length in centimeters or millimeters
Sol PS-1
Lab Equipment
• Graduated cylinder
• Spring scale
• Measures liquid volume, metric unit is milliliter or liter, read bottom of meniscus
• Measures force in Newtons
Graphs
• Bar graph
• Line graph
• Demonstrates change that is not continuous.
• Indicates trends when the data cover a long period of time.
• Demonstrates continuous change.
• Independent variable is on the X axis
• Set of data called a data pair.
Graphs
• Circular graph • Shows how each group of data relates to all of the data.
• Each part represents a category of the data.
Scientific Terms
• Density
• Weight
• Mass
• The amount of matter per given volume.
• D=Mass/Volume
• A measure of the gravitational force on an object, varies with location
• The amount of matter in an object
Scientific Terms
• Volume • The amount of space that matter occupies
• Liquid volume is measured with a graduated cylinder (mL or L)
• The volume of a solid is measured with a metric ruler (LxWxH) which is cubic centimeters
Scientific Terms
Independent variable
Dependent variable
• Also called the manipulative variable
• This is the variable that causes the change, the one you can control
• Located on the X axis
• Also called the responding variable
Scientific Terms
• Dependent variable
• Constant variable
• Control
• Is the result of the manipulated variable
• Located on the Y axis
• Factors or variables that stay the same
• The group that does not get any special treatment
Scientific Terms
• Scattergrams or Scatter Plots
• A graph that shows the relationship between two sets of data.
• Two sets of data are graphed as ordered pairs on a coordinate plane.
• Often shows a pattern, trend, or relationship between the variables
Scientific Terms
• Histograms • Type of bar graph used to display numerical data that have been organized into equal intervals.
