Week 3 Lab Exercise: Determining the Dew Point Temperature AV115: Weather and Climate

Materials:

Thermometer

1 cup size metal container (non-insulated)

Ice

Approximate time: 2 hours

Instructions:

Fill the metal container with warm tap water (at least 50 F in the winter and 75 F in the summer).

Place the thermometer in the water and begin to slowly add ice while continuously stirring the mixture.

Record the temperature when the first sign of condensation begins to appear on the outside of the container. This reading should be within about 3 F of the dew point temperature.

Compare your recorded temperature to the dew point temperature given on your local weather report. Repeat this process once or twice per day for 2 to 3 days to see if you are consistent in the outcome.
