ScienceData Collection <br />For the Interactive White Board Using a Variety of Sensors and a <br />Vernier Go! Link USB Computer Interface<br />
This session will show you how to connect a Go! Link or other computer interface to temperature, pressure, voltage, light , motion, and magnetic field sensors for data collection.<br />Light<br />Pressure<br />Voltage<br />Motion<br />Stainless Steel Temperature<br />Magnetic Field<br />Temperature<br />
Data Collection Interfaces <br /><ul><li> The simplest and least expensive interface is a Vernier Go! Link ($60)

Using a Magnetic Field Sensor<br />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? <br />
<ul><li>What is the relationship between distance and magnetic field strength?
What other forces behave this way?</li></ul>Actual graph of Distance (cm) and Magnetic Field Strength (mT) <br />
A Light Sensor can be used to conduct a similar experiment to show that light intensity vs. distance follows the inverse square law. <br />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.<br />This lab activity is found in :<br />Physical Science with Vernier<br />By Donald L. Volz and Sandy Sapatka<br />The link below has directions for the lab activity. “How Bright is the Light?”<br />http://www2.vernier.com/sample_labs/PSV-25-COMP-how_bright_is_light.pdf<br />
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.<br />Try this experiment!<br />

<ul><li> Move a magnet up and down inside a solenoid that is connected to a voltage sensor.
What happens if you don’t move the magnet?</li></li></ul><li>Graph of Voltage as a Magnet is Moved Inside a Solenoid<br />
<ul><li> 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.</li></li></ul><li>Graph of Temperature as Water is heated and boils.<br /><ul><li>Was your prediction correct?
Why does the graph stop rising at 100 degrees Celsius?</li></ul>This lab activity is found in Physical Science with VernierBy Donald L. Volz and Sandy Sapatka<br />http://www2.vernier.com/sample_labs/PSV-02-COMP-boiling_temperature.pdf<br />
6. Tell what you think is happening in this graph?<br />
The Motion Detector can be used with a LabPro which connects to the computer through a USB port.<br />http://www2.vernier.com/sample_labs/PSV-36-COMP-velocity.pdf<br />
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.<br />This graph shows velocity/time for the same toy car. The slope of the line is the acceleration.<br />
