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.

Biology

“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.

Chemistry

“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.

Physics

“Newton’s Second Law”

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

• Dynamics Cart and Track System with Go Direct Sensor Carts
• Go Direct Force and Acceleration Sensor and the Dynamics Cart and Track System
• Dual-Range Force Sensor, Low-g Accelerometer, and Dynamics Cart and Track System

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.
