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.

This series of activities demonstrates some effects of rising levels of greenhouse gases on climate. Specifically, it shows how an increase of heat-trapping gases in the atmosphere raises temperatures; higher temperatures affect the water cycle, and rising sea levels could affect coastal areas as a result of glacial and polar ice melt. Although these activities are designed to teach specific skills ... Full description.

This three-part module covers the major concepts of the chemistry of water, at a level appropriate for late primary and early intermediate learners. Key vocabulary words are defined using examples that are relevant to children's lives. Each part of the module contains an activity or experiment to reinforce the science content that was covered. Full description.

Students participating in this lesson will collect, observe, and record particulates from the air to contrast visible and invisible air pollution. They then complete a simulation of the damage due to acid rain to illustrate invisible pollution. The lesson plan provides essential elements, objective, focus, a list of materials, background information, procedure, and ideas for enrichment. Full description.

These science bulletins from the American Museum of Natural History feature news on space science, astronomy, and astrophysics topics with in-depth feature stories about cutting-edge developments, weekly images from observatories around the world and in space, and and 'Astro Viz', a visualization of astronomical or astrophysical phenomena. Each story features a link to an educators' guide and links ... 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.

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.

The information on this site indicates that the life cycle of a glacier is more eventful than it appears. The site allows students to follow the journey of a single snowflake as it takes a ride through a glacier, a process that can take as much as 30,000 years to complete. It can be viewed as an interactive slide show or a single page of text and illustrations. Full description.
