Vernier Equipment UNDERSTANDING THE BASICS OF VERNIER TECHNOLOGY
Vernier Equipment UNDERSTANDING THE BASICS OF VERNIER TECHNOLOGY AND TOOLS PART 1: INTRODUCTION – GETTING TO KNOW LABQUEST
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
What can you do with Vernier? �Gather and Log Data �Analyze, Plot, Graph Data �Utilizing Technology and Applications �Building on Inquiry Model
Why use computer based lab equipment?
Tools
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)
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
Built-In Applications Built in Applications �Periodic Table – Table of elements �Stopwatch – Timer �Sound Recorder – Records sound using built in or external mic
Built-In Apps �Periodic Table
Built-In Apps �Stopwatch
Built-In Probe/Sensors �Thermometer
Viewing Modes for Lab. Quest 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
Recording Data �Tapping the “Play” icon Play Icon
Analyzing Data �Tangent - This will draw a tangent line and display the slope for a particular point on graph Select checkbox Slope value
Analyzing Data �Integral- This will integrate (sum up) the value underneath your curve (graph line). Select checkbox Area under curve Numerical value of area
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
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
