Students compare real-time Earth and Mars measurements for temperature, wind speed, humidity and atmospheric pressure by accessing Internet-data resources from NASA.
Activity 1: Make predictions about the current weather data in your area.
Exploration - Real-Time Weather Data for Your Town
Meteorologists often report the temperature, humidity, wind speed and barometric pressure. Make predictions about the current weather data in your area.
2. What do you think the current wind speed and direction is? _____________
3. What do you think the barometric pressure is right now?________________
4. How do you think the barometric pressure is changing? ________________Activity 2:
The Internet is filled with scientific data about cities close to where you live. Use the WWW to find the current temperature, wind speed, wind direction, and barometric pressure in your area. Try the National Weather Service, The Weather Channel or Intellicast WWW sites first. You might even like to try Internet Weather-Cams.
2. What is the current wind speed and direction? _________________
3. What is the current barometric pressure? _________________
4. How is the barometric pressure changing? _________________
6. How well do the Internet
data agree with your predictions of what you see outside?
7. What would you expect the
weather to be if the temperature was 85 degrees F, the wind 10 mph from
the West, and the barometric pressure is 30.15 inches and rising?
8. How would you characterize
a cloudy, cold, winter day using weather data?
