K–12 Experiments of the Month: Elevate Hands-On STEM Learning

Featured Experiment for K-12

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 classes.


Cell Respiration (CO2 and O2)

To conduct this experiment, students use the Go Direct® CO2 Gas Sensor and Go Direct O2 Gas Sensor (or the CO2 Gas Sensor and O2 Gas Sensor). The objectives of the experiment include

  • Measure gas production.
  • Study the effect of temperature on cell respiration.
  • Determine whether germinating peas and non-germinating peas respire.
  • Compare the rates of cell respiration in germinating and non-germinating peas.


Investigating Commercial Hand Warmers

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 the Go Direct Temperature Probe or the Stainless Steel Temperature Probe. The objectives of the experiment include

  • Determine the temperature change of two substances as they dissolve in water. 
  • Test several substances to determine which one can make the best hand warmer based on two factors: enthalpy of solution and cost.


Newton’s Second Law

This experiment can be conducted with several different combinations of equipment:

The objectives of the experiment include

  • Collect force and acceleration data for a cart as it is moved back and forth.
  • Compare force vs. time and acceleration vs. time graphs.
  • Analyze a graph of force vs. acceleration.
  • Determine the relationship among force, mass, and acceleration.
