How does temperature change during a storm?

Temperature sensor

• observing and describing the properties, locations, and movements of the sun, moon, clouds, and airplanes
• understanding that weather changes from day to day and over the seasons
• realizing that weather can be described by measurable quantities, such as temperature, wind direction and
  speed, and precipitation
• understanding that changes vary in rate, scale, and pattern, including trends and cycles
• manipulating and using simple instruments, such as temperature sensors to provide more
  information than scientists obtain using only their senses
• developing good explanations based observations (evidence) and what they already know about the world
  (scientific knowledge)
• developing abilities to work individually and collaboratively and to use suitable tools, techniques, and
  quantitative measurements when appropriate

Be observant of any weather warnings and obey storm safety instructions.

2. Enter your zip code at left-hand corner at the top of the page. Observe and record current weather conditions and the 5-day forecast.

How do you think the temperature will change during a storm? Explain in words and use the pencil in the graph below to show your prediction. Us the annotation tool to label the graph.

1. For up to 3 days prior to the storm, journal daily how the sky, cloud covering and wind changed during the day. Drawings of cloud types can be added to your journal.
2. Connect the temperature sensor outside in an area the is not temperature controlled. This could be a classroom with an opened window or a porced in area to protect the computer.
3. If your computer sleeps after so much time, disable this function so that the computer can continuously record temperature.
4. Start recording temperature 1 day prior to the storm. Continue recording temperature 1 day following the storm.

1. How did your prediction match the temperature collected?
2. What was the minimum and maximum temperature recorded?
3. How did the change in temperature during the day relate to the change in temperature during the night? Could you see a regular, repeated pattern of the temperature data?

1. How did your observations of the sky and cloud covering coincide with changes in temperature?
2. Did the temperature change suddenly around storm time?
3. How did this temperature rate change compare to the temperature rate changes between day and night?

• Try tracking another storm, but this time use a relative humidity sensor. Did your graph show the exact time of the sotrm?
• Set up a dew point sensor that collects data over a week period. By looking at the changes in dew point, can you predict an upcoming storm?
