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.
- Observe how transpiration relates to the overall process of water transport in plants.
- Use a gas pressure sensor to measure the rate of transpiration.
- Determine the effect of light intensity, humidity, wind, and temperature on the rate of transpiration of a plant cutting.
- Write equations for the dissociation of compounds in water.
- Use a conductivity probe to measure the conductivity of solutions.
- Determine which molecules or ions are responsible for conductivity of solutions.
- Investigate the conductivity of solutions resulting from compounds that dissociate to produce different numbers of ions.
This experiment can be conducted with several different combinations of equipment:
- Dynamics Cart and Track System with Go Direct Sensor Carts
- Dynamics Cart and Track System with Motion Encoder, Dual-Range Force Sensor, and Bumper and Launcher Kit
- Dynamics Cart and Track System, Motion Detector, Dual-Range Force Sensor, and Bumper and Launcher Kit
The objectives of the experiment include
- Measure a cart’s momentum change and compare it to the impulse it receives.
- Compare average and peak forces in impulses.
