This United States Geological Survey site focuses on water and its properties. The site contains activities for teachers and students, along with pictures, data, maps, and an interactive center where users can give opinions and test their water knowledge. Unique aspects of this site include the sections that contain student work and a picture gallery. There are links to other resources for students, ... Full description.

The Federal Emergency Management Agency (FEMA) deals with natural hazards such as hurricanes, floods, national security matters, winter storms, etc. in a non-threatening scientifc and fun manner for children. The site includes animations, videos, games, quizzes and questions areas that address hazardous situations that children may face at any given time. Full description.

In this activity, students construct a "comet" from ingredients similar to those found in actual comets. They will learn about the behavior of a real comet by observing their model as the dry ice sublimates, and understand the concept of scale as they compare the size of their model to the size of a real comet. A list of materials and instructions are provided. This activity can be performed as a ... Full description.

This site presents a good overall introduction to hurricane science at the elementary level. Topics include: Weather Instruments, Killer Storms, Surviviors, and Inside a Hurricane. Each section has activites and/or simple explanations of the topic. Full description.

This lesson enables students to explore how water moves through the hydrologic cycle, eventually making its way to their drinking glasses. They will explore the components of Earth's hydrosphere, including surface and subsurface features, and prepare a diagram illustrating the path their drinking water follows as it cycles from the place of precipitation to their own faucets or taps. Assessment materials, ... Full description.

Ships travelling between Lake Ontario and Lake Erie use the Welland Canal. Beginning with a conversation between characters Mathise, Geo, and Trig, they explain how a lock in the canal operates by gravity alone, without pumps. The characters use mathematics to solve problems such as how long the locks take to fill and how to express the volume and flow of water in more common terms (bathtubs of water ... Full description.

Flowing water from rivers and streams is a valuable and plentiful energy resource that people learned to use centuries ago to operate the machinery that was important to their livelihoods. This page features diagrams (some animated) that show the three main principles of water; various types of water wheels; and the modern hydroelectric turbine. There are also animations of various types of mills ... Full description.

In this lesson, students test for visible and invisible pollutants in the air and keep a journal of experimental results, procedures, and conclusions. Using simple materials, they will form groups to set up experiments around the school, keep records, research the history of acid rain, make a mural showing the acid rain cycle, and post a chart displaying the sources of visible pollutants.

This standards-based module uses hands-on activities and real-time data investigations to allow students in the elementary grades to investigate weather phenomena both locally as well as in other places around the world. By using hands-on activities and real-time data investigations, the students will develop a basic understanding of how weather can be described in measurable quantities, such as temperature, ...
