Unlock Scientific Innovation with These College Experiments

Vernier offers more than 1,000 experiments in biology, chemistry, engineering/robotics, and physics that can promote STEM literacy and help you integrate data-collection technology into your courses.


Transpiration of Plants

To conduct this inquiry experiment, students use the Go Direct® Gas Pressure Sensor or Gas Pressure Sensor. The objectives of the experiment include

  • Measure transpiration rates under different conditions. 
  • Use reference sources to find out more about transpiration before choosing and investigating a researchable question. Some topics to consider are listed below:
    • transpiration
    • cohesion-tension theory
    • water potential
    • osmosis
    • stomata
    • water potential gradient
    • xylem
    • mesophyll cell

Determining the Mole Ratios in a Chemical Reaction

To conduct this experiment, students use the Go Direct Temperature Probe or Stainless Steel Temperature Probe. The objectives of the experiment include

  • Measure the enthalpy change of a series of reactions.
  • Determine the stoichiometry of an oxidation-reduction reaction in which the reactants are known but the products are unknown.


Simple Harmonic Motion: Kinematics and Dynamics

To conduct this experiment, students use the Motion Detector, Dual-Range Force Sensor, and Springs Set.

The objectives of the experiment include

  • Collect position vs. time data as a weight, hanging from a spring, is set in simple harmonic motion (SHM).
  • Determine the best-fit equation for the position vs. time graph of an object undergoing SHM.
  • Define the terms “amplitude,” “offset,” “phase shift,” “period,” and “angular frequency” in the context of SHM.
  • Predict characteristics of the corresponding velocity vs. time and acceleration vs. time graphs, produce these graphs, and determine best-fit equations for them.
  • Relate the net force and acceleration for a system undergoing SHM.
