Instruction Guide: NXT View Mode - UNDER CONSTRUCTION

Printer-friendly version

(((The current version of this and all the other Instructor’s Guides based on what I anticipate teaching as I move through this curriculum for the first time in the 2012-2013 school year. I anticipate doing heavy revisions to these documents during each of the first 3 years I present this course. If you have any suggestions regarding any of the ideas surrounding the presentation of this lesson or this course please submit them to the google forms feedback page at this link.)))

The primary task in this lesson is for students to get an introduction the NXT and how it collects, displays, and organizes data. The View Mode Worksheet will be the primary mechanism for this instruction. The version of this worksheet used in robotics does not include the temperature sensor. The version I will use in Data Logging will probably use the touch sensor, but I do not anticipate using this sensor very much as we construct interesting science inquiry activities with sensors.

Begin by going over the inputs and outputs of the NXT, along with the power button, and the battery installation and removal. Show how the USB works, and then show how the sensors are connected.

The NXT also has a file structure for programs, data, and other memory related things. Kids will need to become familiar with this basic structure and how to navigate through it.  Kids will also need to be taught the importance of keeping an eye on battery life indicator or their activities can come to an unexpected finish and they won’t be done.

From here the students are ready to work their way through the View Modes Work Sheet.

View Mode Exercise

Have student power up NXT bricks Walk students through NXT top level men using left/right buttons

  • Projecting page 5 from the NXT Quick Start Guide may be helpful
    • My Files – this is where the programs that students create will be stored.
    • NXT Program – used to write programs directly on the brick (no computer involved).
    • View Mode – used to view sensor values. We will use this mode today.
    • Bluetooth – used to wirelessly connect the NXT to another NXT, or a computer, or another Bluetooth enabled device. We will use this is in advanced units.
    • Settings – used to control features of the NXT. We will use this right now.
      • Have students select Settings (by pressing the orange select button)
      • Have student select Volume from the sub-menu
      • Have student lower volume to “1” (by pressing left/right button)
      • Back out to top level menu (by pressing grey back button)
    • Try Me – used to run sample programs.

Navigate top level menu back to “View Mode” and select it Walk students through View Mode menu using left/right buttons

  • Notice that several menu option have a “*” at the end of their name
    • These denote older generation sensors which we will NOT be using. Student should bypass these choices.

Have students work through the "NXT View Mode" Worksheet to explore the function of each of the sensors.

See the Answer Key for the "NXT View Mode" Worksheet for the key learning students should take away for each of the sensors.
