science exam 2nd qtr

• line graphs - used to track changes over short and long period of time
• when smaller changes exist, line graphs are better than bar graphs
• used to compare changes over some period of time for more than one group
• interpolation - works within the given data set
• extrapolation - works beyond the given data set
• anomalous result - unsignificant result
• hyperbola

  
• parabola

  
• direct relationship - k = y / x
• inversely proportional - k = xy
• measurement - act of determining a targets size, length, weight, capacity, or other aspects
• base unit

  • fundamental unit
  • can express themselves w/o the assistance of other units
• derived unit

  • cannot be expressed in the absence of fundamental units
• parallax - observers displacement of an object caused by change of observer's POV
• metric system - measure weight, distance, and volume
• length

  • meterstick
  • tape measure
  • micrometer

  • dropper
  • measuring cup
  • measuring spoons
• mass

  • triple beam balance
