2. Why use Vernier or Computer Based Labs? Stanford Kuo Lab Experience Using Technology to Focus on Data Providing Hands-On Experience Moving Towards 21 st Century Skills in Classroom

3. What can you do with Vernier? Gather and Log Data Analyze, Plot, Graph Data Utilizing Technology and Applications Building on Inquiry Model

4. Why use computer based lab equipment?

5. Tools

6. Navigating Main Menu Here is what the home screen looks like. Can navigate via three different options.  Front panel buttons  Fingertips  Stylus (plastic pen stored on back of unit)

7. Built-In Applications Built in Applications Labquest App – This is the one used in conjunction with the probes. Power Amplifier – Used for generating electronic signals Audio Function Generator – Used for creating different tones at different frequencies

8. Built-In Applications Built in Applications Periodic Table – Table of elements Stopwatch – Timer Sound Recorder – Records sound using built in or external mic

9. Built-In Apps Periodic Table

10. Built-In Apps Stopwatch

11. Built-In Probe/Sensors Thermometer

12. Viewing Modes for LabQuest App Speedometer Icon – Displays current reading of sensor Graph Icon – Displays graph of measured data (typically is measured against time) Chart Icon – Displays chart of data in table format Speedometer icon Graph Icon Chart Icon

13. Recording Data Tapping the “Play” icon Play Icon

14. Analyzing Data Tangent - This will draw a tangent line and display the slope for a particular point on graph Select checkboxSlope value

15. Analyzing Data Integral- This will integrate (sum up) the value underneath your curve (graph line). Select checkbox Area under curve Numerical value of area

16. Analyzing Data Statistics- This will provide statistical data of you graph on the right hand side of the screen. You can scroll through it by tapping on the arrows on the screen with your stylus. Select checkbox Use scroll icons to see further values

17. Analyzing Data Curve Fit - * For future experiments, select the model that best represents your data.  Pick one of the curve options. The Root Mean Squared Error (RMSE) value at bottom right determines how far off you are. This value should be as small as possible for the most precise curve fit formula. Select checkbox Choose Fit (linear) RMSE
