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

“Transpiration”

To conduct this experiment, students use the Go Direct^® Gas Pressure Sensor or Gas Pressure Sensor. The objectives of the experiment include

• 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.

Chemistry

“Properties of Solutions: Electrolytes and Non-Electrolytes”

To conduct this experiment, students use the Go Direct Conductivity Probe or Conductivity Probe. The objectives of the experiment include

• 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.

Physics

“Impulse and Momentum”

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.
