1. ScienceData Collection For the Interactive White Board Using a Variety of Sensors and a Vernier Go! Link USB Computer Interface

2. 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. Light Pressure Voltage Motion Stainless Steel Temperature Magnetic Field Temperature

4. It uses the included Logger-Lite Software.

5. It will work with 36 sensors.

6. Also available are Go! Temp ($39) and

7. Go! Motion ($99)Vernier Go! Link USB Interface Go! Products Demo: http://www.vernier.com/go/index.html

8. Using a Magnetic Field Sensor 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?

10. Does this graph match your prediction?

11. What other forces behave this way?Actual graph of Distance (cm) and Magnetic Field Strength (mT)

12. 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.

Volz and Sandy Sapatka The link below has directions for the lab activity. “How Bright is the Light?” http://www2.vernier.com/sample_labs/PSV-25-COMP-how_bright_is_light.pdf

13. 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!

14. Measuring the voltage of a Lemon Battery http://www2.vernier.com/sample_labs/PSV-33-COMP-lemon_juice.pdf This lab activity can be found in Physical Science with Vernier By Donald L. Volz and Sandy Sapatka

16. Predict the graph that will result.

20. Why does the graph stop rising at 100 degrees Celsius?This lab activity is found in Physical Science with VernierBy Donald L. Volz and Sandy Sapatka http://www2.vernier.com/sample_labs/PSV-02-COMP-boiling_temperature.pdf

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

22. The Motion Detector can be used with a LabPro which connects to the computer through a USB port. http://www2.vernier.com/sample_labs/PSV-36-COMP-velocity.pdf

23. 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.
