NWS JetStream Learning Lesson: Water, Water Everywhere
Water is the most abundant and important substance on Earth. It is essential to life and is a major component of all living things. There are approximately 336,000,000,000,000,000,000 gallons of water on the earth, existing in three states; solid, liquid and gas. The sources for this water storage are the oceans, icecaps & glaciers, ground water, fresh-water lakes, inland seas, soil moisture, atmosphere, and rivers. The students will be surprised how little water is found in each of the remaining beakers. Despite the over abundance of rain we often receive, the atmosphere contains very little of the earth's total water supply. Fast Facts A cubic mile of water equals more than one trillion gallons. The 48 contiguous United States receives a total volume of about 4 cubic miles (6.4 cubic km) of precipitation each day. Flash floods are the deadliest natural disaster in the world.

How to Use Weather Maps to Make a Forecast - Weather Lesson Plan
Purpose of lesson The purpose of the lesson is to use meteorological data on a weather map, including a variety of weather map symbols, to predict weather events and produce a mock forecast. The intent is to show how data is collected and analyzed. Students first analyze a weather report to discover its parts. They then use these same techniques to analyze weather data. Objectives Given wind speed and direction data in a weather station model from various locations around the United States,correctly label the map with the locations of high and low pressure zones.Given temperature data on a United States isotherm map, chose the correct frontal boundary from the four types of frontal boundaries and draw it on the map so that a forecast can be produced. Resources Materials needed for lesson Teacher needs to collect the daily newspaper forecast for 5 days in advance of the lesson. A computer projector (and a computer) would be helpful in reviewing the online Jetstream school. Background
NOAA/NASA SciJinks :: Why do leaves change color?
Colorful fall leaves. Photo by Jeremy Baucom (Flickr Creative Commons) In the fall, trees put on a pretty impressive fashion show. It all starts inside the leaf. Chlorophyll (greens) Xanthophylls (yellows) Carotenoids (oranges) Anthocyanins (reds) Leaves are green in the spring and summer because that’s when they are making lots of chlorophyll. The summer sunlight triggers the leaves to keep making more chlorophyll. As summer fades into fall, the days start getting shorter and there is less sunlight. Shorter days in the fall are a signal for trees to start preparing for winter. Weather is also an important part of the color change. Extreme weather changes can also have an effect on the leaves. So if you want to know how long the colors will last this fall, be sure to keep an eye on the weather!
Global Warming is Affecting Weather
Global warming is making hot days hotter, rainfall and flooding heavier, hurricanes stronger and droughts more severe. This intensification of weather and climate extremes will be the most visible impact of global warming in our everyday lives. It is also causing dangerous changes to the landscape of our world, adding stress to wildlife species and their habitat. How is Climate Change Impacting Weather-Related Events?
