Cycles on Earth and in Space
This section of Water Science for Schools from the U.S. Geological Survey offers information on where, how much, and in what forms water exists on Earth.
Students can envision the water cycle by following a drip of water around as it moves on its way. They could really begin this story anywhere along the cycle, but the ocean is where the story begins since that is where most of the Earth's water is. Students can click on the Water Cycle Graphic to view or print it.
Kids Zone Water Cycle
The earth has a limited amount of water. That water keeps going around and around and around and around and (well, you get the idea) in what we call the "Water Cycle".
What Forces Affect Our Weather?
Students learn what forces affect our weather by exploring the topics on this website. The Atmosphere, water cycle, powerful storms, ice and snow and forecasting are all covered. There are links to other web sites that relate to weather also.
This web page explains the determining factors that affect weather and the information can be viewed at three different reading levels. The page can be presented in Spanish and adjusted to any one of the reading levels too.
How to Read a Weather Map
This web page introduces students to all the common symbols found on weather maps on television and in the newspaper.
Weather Wiz Kids
This page explains which weather instrument measures what, and how the instrument works. This site also includes information on all aspects of weather including hurricanes, tornadoes, winter storms, and much more.
This interactive site from Scholastic allows students to 'test drive' the tools meteorologists use every day. Students click on each tool for more information along with instructions on building it and using it in an experiment.
Earth and Its Place in the Solar System
The Bodies in our Solar System
Students can click on individual planets or on other bodies in our solar system including asteroids, comets, meteoroids, or Kuiper Belt Objects to learn more about them. On the bottom of each page students will find links to pictures, graphics and other relevant sites.
