12. Graphing Calculator

13. Interfaces
CBL 2 – multiple probes Easy Link – single probe

14. Probes
Easy Temp ph sensor

15. Calculator Software – Easy Data
The EasyData App is a graphing calculator application.
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.

16. Commonly used probes & sensors
Temperature pH
Light
Voltage
May actually use the probe or interpret data taken with the probe or sensor

17. Sample Procedure
Turn on your TI-84 Plus 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

18. 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.

19. Probe Setup Graphing calculator Easy link or CBL Probe
Collect data onto calculator
Graph analysis
Quick data collection

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

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