Make a climate station

Atmospheric scientists examine climate processes, the worldwide dynamics of local weather, photo voltaic radiation and its results, and the function of atmospheric chemistry in ozone depletion, local weather change, and air pollution. They observe what is going on on in our ambiance right now and examine it to information from years previous. To observe the climate, atmospheric scientists use extremely specialised devices that measure rainfall, wind velocity and route, humidity, and atmospheric strain. You possibly can measure these at your own home or college. Start making a climate station by constructing a psychrometer, additionally referred to as a hygrometer, to measure the relative humidity.


  • Two alcohol-filled air thermometers (they have to learn precisely the identical temperature when positioned facet by facet out of direct daylight)
  • Clear packing tape
  • Cotton shoelace (the hole kind)
  • One- or two-liter bottle (label eliminated)
  • Water (distilled is finest however faucet will do)
  • Thread
  • Axe
  • Relative humidity chart


  1. Have an grownup punch a gap within the facet of the bottle about an inch from the underside. Heating the axe will make an ideal gap. The identical factor will be performed with a scorching nail held with tongs. Use nice warning when doing this so you do not burn your self or others. Once you’ve made the opening, place the new object in chilly water.
  2. Lower the information off the shoestring. Lower about two inches of shoestring and slip it over the bulb of one of many thermometers. Fastidiously tie it in place with thread.
  3. Lower a small piece of packing tape. Place the bulb of the shoestrings thermometer about 1/eight inch over the opening. Make certain the highest of the thermometer is aligned with the highest of the bottle. Tape the thermometer to the bottle. Tape the opposite thermometer parallel to the primary one and about 1/four inch away. Put a strip of tape across the bottle and each thermometers to verify they do not fall off.
  4. Push the shoelace by means of the opening. Put room-temperature water within the bottle till it reaches slightly below the opening.
  5. Wait 5 to 10 minutes, and browse each thermometers. There will probably be a distinction within the two. Use the chart beneath to calculate the relative humidity.
  6. Hold a file of the each day humidity for just a few weeks. Subsequent to your entries, describe the way in which you are feeling on these days.
  7. The dry-bulb temperature may also be used to file the air temperature!
