Eggsperiemnt (Air Pressure)
-hard boiled eggs, flame in bottle, place egg on lip
Prediction:
The air pressure will lower and a seal will be created and the egg will be sucked in.
What happened:
The flame created a quick increase in temperature, so when the seal was created the air pressure dropped so quickly that the egg was sucked into the bottle.
Sling Psychrometer (Humidity) :
We used a sling psychrometer and spun it around for one minute, inside and outside. We compared the temperatures on the dry bulb with the wet bulb to find the relativity humidity.
The air was more humid outside (69) than inside (36).
Measuring clouds:
water vapor, pressure, condensation nuclei(salt, ash, ect)
Water bottle, water, and match
-when you squeeze=high pressure, no clouds, warmer
-let go=low pressure, clouds, colder
Anometer (wind speed): measured with a weather vane
crossing rulers and put cups on each end-count how many times it goes around
Precipitation:
Wet-rain gauge
can by made with a ruler and cup
Dry-1mx1m snow board
