Endurance Tent Experiment
We worked in the local area of Bull Pass today. While we were out I set up an experiment in the tent for my students in Yarmouth which I hope Mr. Pride will find useful.
Problem: Given the following data, is there a correlation between light intensity and the temperature inside the tent? If so, what is it? If not, why not? What other factors could influence the temperature inside the tent?
Setup: The tent was vacant during the entire test. The test lasted for 8 hours with light intensity and temperature measurements programmed to be taken automatically every 15 minutes (900 seconds). The tent is an "Endurance Tent" which measures 8 feet by 16 feet (base) with a 6 foot maximum height in the center.
Equipment: As shown.
- TI-83 Plus graphing calculator (used to program the LabPro)
- Vernier LabPro
- Vernier temperature sensor (degrees Celsius)
- Vernier light sensor (no units - works off a relative setting, 1=100% equals
maximum intensity relative, .50=50%, and so on)
Hint: you might want to convert the relative light intensity to a percentage. Although it isn't necessary, you could convert the temperature readings to Fahrenheit. For details about the sensors, see either Mrs. Evrard who can point you to the technical manuals we have or Mr. Borda who can point you towards the Vernier web site at http://www.vernier.com
