Vernier Go! Link USB Interface

Data Collection Interfaces The simplest and least expensive interface is a Vernier Go! Link ($60) It uses the included Logger-Lite Software. It will work with 36 sensors. Also available are Go! Temp ($39) and Go! Motion ($99)

Which part of the magnet has the greatest magnetic field strength? What will happen to the strength of the magnetic field as the magnet is pulled away from the sensor?

Using a Magnetic Field Sensor

What is the relationship between distance and magnetic field strength?

Does this graph match your prediction?

What other forces behave this way?

Actual graph of Distance (cm) and Magnetic Field Strength (mT)

A Light Sensor can be used to conduct a similar experiment to show that light intensity vs. distance follows the inverse square law. Light Intensity = 1/d2. If you could make a graph of distance from the center of earth vs. gravity it would also show an inverse square.

The link below has directions for the lab activity. “How Bright is the Light?”

Use a gas pressure sensor and a syringe to see what happens to the pressure as you decrease the volume of air in the syringe.

Try this experiment!

Move a magnet up and down inside a solenoid that is connected to a voltage sensor. Predict the graph that will result.

What happens if you don’t move the magnet?

What will happen to the temperature of the water as it is heated for a long time on a hot plate? Draw your prediction on a graph.

Graph of Temperature as Water is heated and boils.

Was your prediction correct? Why does the graph stop rising at

100 degrees Celsius?

6. Tell what you think is happening in this graph?

The Motion Detector can be used with a LabPro which connects to the computer through a USB port.

This graph using Logger Pro shows position/time for a battery powered car. The slope of the line is the velocity. Notice extra analysis features in Logger Pro.

This graph shows velocity/time for the same toy car. The slope of the line is the acceleration.
