Equipment Needed

• TI Graphing Calculator (82, 73, 83, 83, 84, 84,
  92, 92)
• Calculator Based Ranger (CBR)
• Calculator-to-Calculator Cable

3
Conic Distribution of Sound Clicks

• Remember that the cone is three-dimensional

4
Buttons we will be using

• On
• Enter
• Apps
• Arrows
• 2nd

5
Set-up

• Plug one end of the cable into the bottom of the
  TI Graphing Calculator
• Plug the other end of the cable into the
  Calculator Based Ranger (CBR)
• As shown in the two images

6
Real-life Set-up
7
Steps Part 1

• Turn on the Calculator
• Click the Apps buttonAnd you will see a screen
  similarto the one shown
• Choose CBL/CBR and press Enter
• Follow the screenDirection (Press Any Key)Till
  you reach the following screen and then
  choose3Ranger

8
Steps Part 2

• Youll see this screen next and then you should
  press the Enter key
• Then youll see the following screen. Choose
  1Setup/Sample and press Enter
• To arrive at the following set of options

9
Steps Part 3

• Change options to read as shown. Scroll through
  options and press Enter to change options.
• Scroll up to Start Nowand press Enter to
  arrive at one of the following screens. The
  second is an error make sure your cables are
  properly plugged in.
• Once the CBR and TI are speaking with one
  another and you click Enter you will hear a
  series of clicks.

Starting Out Using the Distance Sensor

• Now that we know how to set up the equipment
  lets start using it
• Point the distance sensor at an object and the
  user moves the sensor, or
• The user or another object (like a ball) is moved
  or moves in front of the distance sensor

11
User Points at an Object and moves with the
Distance Sensor

• An effective way for a single student to conduct
  experiments and create and explore graphs
• The idea is that the user operates their own
  devices and creates their own graphs through
  their movements with the distance sensor and a
  stationary object

12
User or Object Moves in Front of Distance Sensor

• The mover or an object (like a ball) moves in
  front of the distance sensor while someone else
  operates the collect button.

My attempt at the wave graph

• As you can see my attempt is not the same as the
  intended graph. Its close but fortunately
• I can try again by pressing Enter after my
  graph choosing 3 Repeat Sample

15
Create your own graph and draw it

• Create your owngraph and draw it in the screen
  shown and explain the procedure to create it
  below

16
Graph Analysis

• Determine High and Low Points
• Determine Slope over an interval by calculating
  the Change in Y over the Change in X for points
  chosen

17
The Gauge Option

• From the Main Menu choose 1Gauge Hint may
  have to move through the apps menu sequence
  again.
• You will then be prompted with some options
• The Bar option is shown
• The Meter option is shown

18
The Data Logger Option

• There is another way to create graphs
• From the Main Menu choose 2Data Logger Hint
  may have to move through the apps menu sequence
  again.
• You will then be prompted with some options
• The most important are Samples and
  Intrvl(sec) and RealTme
