Activity 1 - View NOVA Video
NOVA: Absolute Zero: Part One, The Conquest of Cold
- Video - NOVA: Absolute Zero, The Conquest of Cold (first 52 mins)
- Transcript
- Part One, "The Conquest of Cold," opens in the 1600s when the nature of cold and even heat were a complete mystery. Are they different phenomena or aspects of some unified feature of nature? Are they added to a substance or qualities of the substance itself? The experiments that settled these questions helped stoke the Industrial Revolution, which exploited such fundamental insights as that heat always flows from hot to cold.
a) Watch video,
b) take notes in carbon copy (CC) lab notebook,
- - make note of all historical names mentioned and in what context are they noted (you might need to expand on this later)
- - make note the years
- 1) Document all historical people mentioned throughout the program (please use web or transcript linked above to correct all name spellings),
- 2) At ~4.50 min there is an experiment done with salt/ice/water...describe and briefly explain...
- 3) At ~8:45 min there is an experiment done by Boyle...describe and briefly explain...
- 4) What tool did Boyle need to make his research better? (hint: ~11 mins)
- 5) List the names of the 3 thermometer scales...2 are mentioned first (~12 mins) then the 3rd later...
- 6) Who proposed the erroneous "Caloric Theory"?
- 7) Who disproved the "Caloric Theory"?...and what did this person have in common with the person who proposed the theory?
- 8) What was Tudor's 1st "ice" ship called?
- 9) What was the name of the book written by Carnot?
- 10) What job did James Prescott Joule hold while developing his contribution to thermodynamics?
- 11) Who is attributed to inventing the frozen food industry?
- 12) Who is attributed to inventing "air cooling"?
c) turn in CC (at end of lab period).
Activity 2 - Laptop Check/Igor
a) Install Igor software on your computer...go to here and download version 8.0. Although you can use the software for a 30 day trial, I ask you to register/activate your copy using the info in this image/below (click on it to expand) ->
- VAPG-PDSX-GZLA-XPKY-MJYU-YLUX-KNS <- cut and paste:
b) make a simple Igor plot:
- - wave_01 --> 1, 2, 3, 4, 5, 6
- - wave_02 --> 10, 20, 30, 40, 50, 60
- include axes labels x = time; y = number
c: Import "Load waves":
- - Click here...and then "save as"
- - Note that this file has header information.
- include axes labels x = Magnetic Field (Gauss); y = Intensity
d) Make a new Layout and add both graphs...add you name...then print
