Why does a lot of hail, rain, or snow fall at some times and not others? This 6th grade science unit on weather, climate, and water cycling is broken into four separate lesson sets. In the first two lesson sets, students explain small-scale storms. In the third and fourth lesson sets, students explain mesoscale weather systems and climate-level patterns of precipitation. Each of these two parts of the unit is grounded in a different anchoring phenomenon.

OpenSciEd content is highly rated in EdReports and is aligned to NGSS standards.

Selected resources provide three web-based activities to complement science lessons in an issue of Beyond Weather and the Water Cycle. The free, online magazine for Grades K-5 teachers explores the essential principles of climate literacy.

Hear about how respect for Earth can help us attain a more sustainable lifestyle in the face of climate change in this video segment adapted from United Tribes Technical College.

In this video adapted from KUAC-TV and the Geophysical Institute at the University of Alaska, Fairbanks, Alaska Native students contribute to research on how their environment is changing as a result of global warming.

In this informational text, elementary school readers learn about the difference between weather and climate and about components of the climate system. The text can be used to practice visualizing and other comprehension strategies. Available in K-2 and 3-5 grade bands and as an illustrated book as well as a text document, the story appears in the online magazine Beyond Weather and the Water Cycle.

What would happen if a portion of the Antarctic Ice Sheet were to melt? This video segment adapted from NOVA uses animations to show the effect of a 6-meter sea-level rise on coastal cities across the world.

What happens when the ground under your feet is ice and it's moving? This video segment adapted from NOVA features some of the dangers faced by scientists conducting research in Antarctica.

This article includes links to expository text for students in grades K-1, 2-3, and 4-5 about the climate differences between the Arctic and Antarctica.

The AOML researches oceanography, tropical meteorology, atmospheric and oceanic chemistry and acoustics in order to understand the physical characteristics of the ocean and atmosphere. Explore science in action!

Biology 2e is designed to cover the scope and sequence requirements of a typical two-semester biology course for science majors. The text provides comprehensive coverage of foundational research and core biology concepts through an evolutionary lens. Biology includes rich features that engage students in scientific inquiry, highlight careers in the biological sciences, and offer everyday applications. The book also includes various types of practice and homework questions that help students understand—and apply—key concepts. The 2nd edition has been revised to incorporate clearer, more current, and more dynamic explanations, while maintaining the same organization as the first edition. Art and illustrations have been substantially improved, and the textbook features additional assessments and related resources.

By the end of this section, you will be able to do the following:

Define global climate change
Summarize the effects of the Industrial Revolution on global atmospheric carbon dioxide concentration
Describe three natural factors affecting long-term global climate
List two or more greenhouse gases and describe their role in the greenhouse effect

This interactive resource adapted from NASA describes the different temperature, precipitation, and vegetation patterns in seven biomes: coniferous forest, temperate deciduous forest, desert, grassland, rainforest, shrubland, and tundra.

This article continues an examination of each of the seven essential principles of the climate sciences on which the online magazine Beyond Weather and the Water Cycle is structured. Principle 3 states that life on Earth depends on, is shaped by, and affects climate. The climate dictates where and how species can survive. The author discusses the scientific concepts underlying the life forms' dependence on the climate and expands the discussion with diagrams, photos, and online resources.

What are the factors that make up an ecosystem? Students will be able to identify the biotic and abiotic factors of an ecosystem and explain how they impact each other.

In this video, Paul Andersen describes both weather and climate. Weather refers to the day-to-day conditions on the Earth's surface, including temperature, wind, humidity, air pressure, and precipitation. Climate means the long-term conditions on the Earth's surface. Both climate and weather are determined by sunlight, water, landforms, and life forms. [7:47]

A comprehensive site on Ancient Egypt, including sections on the lifestyle, geography, religion, and politics of the country.

A new instructional model, called Argument-Driven Inquiry (ADI), is introduced to elementary teachers in this article. The author shows how school librarians and classroom teachers can collaborate to help students construct and communicate evidence, or arguments. Evidence buckets, a collaborative activity, and related online resources are presented. The article appears in the free online magazine Beyond Weather and the Water Cycle, which is structured around the seven essential principles of climate literacy.

The CIA World Factbook provides this excellent resource on Argentina. The content includes geography, people, government, economy, communications, transportation, military and transnational issues.
