TI and Science Olympiad Partnership

• 5-year partnership increases opportunities for MS
  and HS Science Olympiad coaches, supervisors and
  students to use technology in events
• Science Olympiad provided every State Director
  with a full set of data collection materials for
  2008 tournament season
• Set includes TI-84 Plus Silver Edition
  Calculator, CBR 2, Vernier Easy Link, temp probe,
  light sensor, pH probe and more
• Professional development for Science Olympiad
  across the US integral part of relationship
• TI committed to supporting tech-based events at
  state and national tournaments

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.
