The Vernier Sensor Suite

 

All high school science programs require sound laboratory investigations.  Although no one would argue with the benefits of such a program, the time and equipment required has often meant it is overlooked or only briefly touched on.  Despite this, research has consistently shown the benefits of such programs.  Educators, both in secondary and post secondary environments struggle find a balance between lecture time and laboratory time.  Secondary schools are also subject to equipment shortage.  Rarely do they have enough equipment for each student to conduct their own experiments.  Rather, students typically work in groups of 3 or 4. Although this allows the schools to get by with less equipment, it diminishes the learning opportunities and is a less than ideal solution.  

 

On its own, the vernier equipment partially solves one of these problems.  Vernier equipment is designed to allow students and teachers to collect data and conduct experiments in a efficient, streamlined manner.  Digital sensors plug into an interface device which provide students and educators with the ability to graph, analyze and interpret data on the spot.  The sensors Vernier produces covers nearly every aspect of secondary science and they are constantly striving to meet the evolving needs of educators.  Vernier now produces more than 50 different types of sensors ranging from motion detectors to pH meters to soil moisture sensors.  A brief list is included below:

  • Accelerometers
  • Charge Sensors
  • Conductivity Probe
  • Current Probe
  • Differential Voltage Probe
  • Dissolved Oxygen Probe
  • Dual Range Force Sensor
  • Flow Rate Sensor
  • Force Plate
  • Gas Pressure Sensor
  • Gas Chromatograph
  • Hand-Grip Heart Rate Monitor
  • Magnetic Field Sensor
  • Motion Detector
  • pH Sensor
  • Photogate
  • Relative Humidity Sensor
  • Spectrometer
  • Temperature Probe
  • UV Sensor
  • Voltage Probe
 

 

 

This greatly reduces the amount of time required both in carrying out the experiments and in analyzing the results.
