WEATHER AND CLIMATE: WHAT’S THE DIFFERENCE? 1 TIME:Introduction:30 minutes Data collection:10 minutes per day (for one or more weeks) Part 1 graphing/analysis:45 minutes Part 2 graphing/analysis:45 minutes Part 3 discussion:15 minutes LEARNING OBJECTIVES: Students will: Learn to collect and graph local weather data Learn to access and understand longer-term local climate data Understand the general distinctions between weather and climate Understand that daily weather measurements are highly variable compared with longer-term climate data NATIONAL SCIENCE STANDARDS: Content Standard A: Science as inquiry Content Standard D: Earth and space science ADAPTED FROM:National Center for Atmospheric Research (NCAR)/University Corporation for Atmospheric Research (UCAR): overy/LIA_lesson1_9.28.05.pdf. DESCRIPTION This lesson plan enables students to learn the differences between weather and climate. Students collect local weather data for a defined period of time, and then compare these data with longer-term climate data for their community. BACKGROUND Weather is a specific event or condition that happens over a period of hours or days. For example, a thunderstorm, a snowstorm, and todays temperature all describe the weather. Weather is highly variable day to day, and from one year to the next. For example, Minneapolis might have a warm winter one year and a much colder winter the next. This kind of change is normal. But when the average pattern over many years changes, it could be a sign of climate change. Climate refers to the average weather conditions in a place over many years (usually at least 30 years, to account for the range of natural variations from one year to the next). For example, the climate in Minneapolis is cold and snowy in the winter, while Miamis climate is hot and humid. The climate in one area, like the Midwest or Hawaii, is called a regional climate. The average climate around the world is called global climate. When scientists talk about global climate change, theyre talking a pattern of changes happening around the world over many years. One of the most important trends that scientists look at is the average temperature of the Earth, which has been increasing for many years. Rising global temperatures are leading to other changes around the world, such as stronger hurricanes, melting glaciers, and the loss of wildlife habitats. That's because the Earths air, water, and land are all related to one another and to the climate. By examining trends in weather and temperature data, along with the changes occurring in all of these systems, scientists can get a good understanding of today’s climate change. MATERIALS Thermometer for recording temperature outdoors A copy of the “Daily Weather Data” worksheet for each day of data collection A copy of the “Instructions for Getting Climate Data (Daily Average Temperature)” for each student or group of students(optional: the educator can look up these data ahead of time and fill in the table before the class to save time)
