A place for insight, inspiration, and 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 classes.
- 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.
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.
- 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.
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.
