Calculator Software – Easy Data
The EasyData App (TI-84) and Data Quest (N-spire) are graphing calculator applications.
lets you collect, view, and analyze real-world data on certain TI-graphing calculators
using Vernier USB devices or probes (Easy Temp and CBR2 motion sensor) which connect directly to the calculator.
![Page 17: 2016-USING TECHNOLOGY FOR PROBLEM-SOLVING IN SCIENCE OLYMPIAD KAREN LANCOUR Life Science Rules Committee Chair](https://reader037.vdocument.in/reader037/viewer/2022103101/5697bf9a1a28abf838c92249/html5/thumbnails/17.jpg)
Commonly used probes & sensors
Temperature pH Light Voltage May actually use the probe or
interpret data taken with the probe or sensor
![Page 18: 2016-USING TECHNOLOGY FOR PROBLEM-SOLVING IN SCIENCE OLYMPIAD KAREN LANCOUR Life Science Rules Committee Chair](https://reader037.vdocument.in/reader037/viewer/2022103101/5697bf9a1a28abf838c92249/html5/thumbnails/18.jpg)
Sample Procedure – TI 84-Plus calculator
Turn on your graphing calculator and make sure that it is on the home screen
Plug the probe into the EasyLink Interface and then plug the EasyLink into the USB port of the graphing calculator.
The EasyData program will automatically start and the Main screen will be displayed
![Page 19: 2016-USING TECHNOLOGY FOR PROBLEM-SOLVING IN SCIENCE OLYMPIAD KAREN LANCOUR Life Science Rules Committee Chair](https://reader037.vdocument.in/reader037/viewer/2022103101/5697bf9a1a28abf838c92249/html5/thumbnails/19.jpg)
Collecting Data – Temp When starting a new data
collection with a probe, select File and then the option New.
Use the Setup menu to select the parameters for data collection.
Select Start to begin data collection.
Once data collection is complete, you will select Graph to choose the options for data analysis.
Finally when you are finished, you will to select Quit to end the data collection session.

Sample Station – Temperature
Use the temperature probe to detect temperature change in a chemical reaction
It could also be done with a traditional thermometer

Sample Station – pH
Determine the pH of various solutions using either pH probe or pH test papers.
