Function Practicum - the CBL

Need volunteers willing to clear their calculators' memories (most of you shouldn't mind doing this, unless you've already installed a lot of cool games, etc.!).
1. 2nd Mem
2. F1
3. All
Yes, you're sure!
Most of you will need to put batteries in your CBL - they're new, and you're using them for the first time! Once you have them fueled, plug the calculator into the CBL.
We need to install software on the calculators:
1. On the calculator:
  1. 2nd Var-Link
  2. F3
  3. Receive
2. On the CBL
  - Transfer
Your calculator should think for a little while (linking), then return from its lobotomy.
We'll hopefully try two experiments (but definitely the first):
1. Temperature Probe:
  Description of the experiment: We're going to have a warm-handed person grab the probe, and we'll watch as the probe warms to their body temperature over the course of a minute. Before you start, predict what your graph of temperature versus time will look like.
  Explicit instructions
  1. The temperature probe should be at an ambient temperature to start.
  2. Plug in your temperature probe (Channel 1 - CH 1 - is fine), and don't warm it up by touching it, etc.!
  3. You will run the datamate program:
    Type datamate() at the command line.
  4. The calculator may "detect sensors", then come back with a menu. The experiment is as follows:
    1. Decide who has the warmest hands.
    2. Use Setup
    3. Use the arrow keys to move down to "mode" line, and hit enter.
    4. Select Time Graph
    5. Change the time settings to be spaced at 1 second, and collect data for a minute.
    6. "OK" back to the main screen.
    7. You should be ready to go:
      1. Warm handed person grab the probe,
      2. Hit 2 to start, and
      3. Hold on!
  5. Explain:
    1. Was the result similar to the predicted function?
    2. What kind of model (from our zoo of functions) would be appropriate? Why?
    3. Can we use mathematics to quickly predict body temperature after only a few seconds of data?
2. The optical sensor
  This sensor detects light.
  1. Using essentially the same set-up, use the sensor to create a graph of an oscillatory (sine-like) function.
  2. How well can you mimic the sine function? What steps do you take to ensure
    - uniform period?
    - uniform amplitude?
