College Experiments of the Month: Unlock Scientific Innovation

Featured Experiment for College

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.


Photosynthesis by Chloroplasts

To conduct this inquiry experiment, students use the Go Direct® SpectroVis® Plus Spectrophotometer or Go Direct Visible Spectrophotometer. The objectives of the experiment include

  • Use a spectrophotometer to measure color changes in DPIP due to photosynthesis by chloroplasts.
  • Use reference sources to find out more about photosynthesis by chloroplasts before choosing and investigating a researchable question. Some topics to consider are listed below:
    • photosynthesis
    • chlorophyll
    • chloroplast
    • ATP
    • NADPH
    • electron transport chain


Synthesis of Methyl Orange and Its Application to Textiles

This experiment aligns with the theme of National Chemistry Week 2022—“Fabulous Fibers: The Chemistry of Fabrics”—and it is a great choice for hands-on chemistry learning all year. 

To conduct this experiment, students use a spectrophotometer. The objectives of the experiment include

  • Synthesize methyl orange from the reaction of a primary amine with nitrous acid.
  • Calculate product purity using a spectrophotometer.
  • Observe the spectroscopic changes of methyl orange under acidic and basic conditions.
  • Explore how organic chemistry is an essential component of the textile industry.


Centripetal Accelerations on a Turntable

This experiment can be conducted with several different sensors:

The objectives of the experiment include

  • Measure centripetal acceleration on a record turntable.
  • Determine the relationship among centripetal acceleration, radius, and angular velocity.
  • Determine the direction of centripetal acceleration.
