Lab 1: We measured two types of temperature - name them?
- air temperature
- soil temperature
Lab 1: What are the names of the instruments that you used
for each of them and how/where did you measure these
temperatures?
- liquid analog thermometer for air measured at 5-6 ft off the
ground and at ground level
- bi-metal dial thermometer for soil measured at 3 inches deep
into the soil
Lab 1: What is the name of the instrument that you used to
determine relative humidity?
sling psychrometer (hygrometer)
Lab 1: How was the sling psychrometer used? This is
complex so explain all steps!
- two thermometers: one normal and the other a wet-bulb
thermometer.
- wet the wick of the wet-bulb thermometer and swing the device
in a circular fashion
- water evaporates from the wet-bulb thermometer
- then record the two measured temperatures
if relative humidity is high, the closer the two temperatures are - at
100% relative humidity the air is holding as much moisture as
possible and there is no difference between the wet-bulb and
regular thermometer
- if the surrounding air is dry the wick dries faster and is cooled
making it read a lower temperature than the regular thermometer
Lab 1: Explain the physical principle on which sling
psychrometer measurement is based upon?
, 2
If the surrounding air is relatively dry, more moisture will
evaporate from the wet bulb, and the drop in temperature will be
higher. If the air is more humid, evaporation will be less, and the
fall in temperature will be lower.
Lab 1: What is the name of the instrument you used to
measure wind speed and explain how this instrument
measures wind speed?
- handheld wind meter
- as the wind speed increases it carries the ball in the tube farther
up the tube
- hold the device at eye level with the back of the unit facing
towards the wind. The position of the white ball in the tube
indicates wind speed in miles per hour
Lab 1: We compared our results to the SHU weather station.
On what web site is our weather published? Why were your
results somewhat different?
- www.wunderground.com
-courtyards temperature was higher than the SHU weather station
is because the courtyard is East-facing toward sun rising,
whereas SHU weather station west-facing the sun setting.
courtyard would experience the effects of the sun before the
weather station
- additionally, weather station was in an open area experiencing
wind straight-on would be higher than the courtyard which is in
the middle of many walls that can block/slow the wind.
Lab 1: rules for using a thermometer
- taken a reasonable distance away from house to avoid hot or
cool air from inside altering the measurement
- shouldn't be exposed to sunlight
- keep away from metal or dark objects
Lab 1: how did we measure long-term microclimates?
- temperature and relative humidity data logger
- light data logger
Lab 1: What four microclimates did we measure?
