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.

Biology

“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

Chemistry

“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.

Physics

“Centripetal Accelerations on a Turntable”

This experiment can be conducted with several different sensors:

• Go Direct Acceleration Sensor
• Go Direct Force and Acceleration Sensor
• Low-g Accelerometer and a LabQuest^® interface 

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.
