Students learn about the composition and structure of the atmosphere and create a large model of it. The activity and accompanying PowerPoint can both be downloaded, and the student handout is provided in both English and Spanish.

This teacher website provides a comprehensive lesson unit on the structure of Earth's atmosphere and how it sustains and impacts life on Earth and its ecosystems. Includes labeled diagrams, student worksheets, a slideshow, flashcards,...

As part of the General Chemistry Virtual Textbook, this site examines a variety of topics related to Earth's atmosphere. Topics covered in the overview include structure of the atmosphere, composition of the atmosphere, energy balance of...

The University of Oklahoma explores numerous types of weather and atmospheric changes, as well as the reasons behind them. Content details the four seasons, common meteorological variables, the vertical structure of the atmosphere, how...

A course lecture on how the Earth's geological features have evolved through the movements of tectonic plates. Explains the different types of plate boundaries and how they manifest in geological formations. Also describes the structure...

Engaging and very informative article that explains what elements are, some of their history, how they are represented, the categories of elements, the periodic table, and how they are structured and classified.

Create a model to help learn the layers and structures within the Earth. Identify characteristics of each layer of the Earth.

In this activity, students will make observations then construct a "sample" model representation of the Earth's layers. They will compare and contrast the movement and material in each layer explaining the location and what it contains.

Find out about the interior structure of the Earth and the role of seismic waves as they move through Earth's layers. The research details both compositional layers as well as mechanical layers.

Information on the features, size, salinity, temperature, ocean floor, currents, and tides of the Atlantic Ocean.

Interactive tutorials on plate tectonics, plates and boundaries, and the Earth's structure convey the dynamism of geologic processes, such as earthquakes and volcanoes. Takes a multidimensional approach to coverage of basic geologic...

This interactive activity adapted from A Science Odyssey Web site helps you visualize different types of plate tectonic activity and shows the impact this activity has on Earth's surface.

Visit an active volcano site to find out the connection between the movement of the Earth's plates and the processes deep within the Earth's interior. [58:23]

Understand the basic structure of atoms and molecules in the Earth's crust.

A comprehensive site covering everything from volcanic structures to pyroclastic materials. View pictures of major volcanic landforms, and volcanic rocks.

Instructional module focusing on minerals. Discussion includes chemical composition, chemical structure, and the formation process. The site also includes an interactive practice quiz and links relating to the topic.
