What is A Weather?<br />The weather is the state of the atmosphere at any time. Weather includes such things as precipitation(rain), temperature, air pressure, and cloud coverage. Weather changes from day to day. Daily changes in weather are due to winds and storms. Trends in temperature and weather conditions tend to be predictable during a season. Seasonal changes are due to the Earth rotating around the sun. <br />

Students know how to use simple tools (e.g., thermometer, wind vane) to measure weather conditions and record changes from day to day and across the seasons.<br /> b. Students know that the weather changes from day to day but that trends in temperature or of rain (or snow) tend to be predictable during a season.<br />c. Students know the sun warms the land, air, and water<br />
