Students examine core samples from Mars and discover what they can use it to tell the history of Mars.  For this core sample lesson students create and analyze their own core samples then eat them at the end.

High schoolers locate and access data to help them with their science inquiry.  For this geographical positioning lesson students evaluate and compare data sets. 

Students view cut-away images of the planets' interiors, comparing and contrasting them with the Earth's in written form. Students also classify each planet as "terrestrial" or "Jovian". The Planet Interiors applet on the CSA website...

Students study plate tectonics.  In this plate tectonics lesson students build a cutaway scale model of the Earth. 

Students study the makeup of the earth, including the core, the mantle and the crust. They compare the temperatures and thicknesses of each layer. In pairs, they make a model of a cross-section of the earth out of modeling clay.

In this earth's layer worksheet, learners label a diagram of the earth's layers. They are given 4 terms and their definitions to read and students determine which layer is which on the diagram based on the definitions.

Students study and classify soil. In this soil science lesson, students classify soil by texture and size and study soil horizons. Students label the soil types with their specific soil horizon and learn about permafrost. Students...

This PowerPoint provides a multiple choice and fill-in-the-blank format for reviewing vocabulary and related content following an "earth's crust" science unit. The information is concise and age-appropriate and the font and colors are...

Students interpret a rock core sample from a clay model. In small groups, they layer modeling clay in a plastic container using coarse-grained spices sprinkled in to represent fossils. They switch containers with another group and remove...

Third graders draw what they believe is in space on a dry erase board. In groups, they are given a beaker half filled with water and they add a teaspoon of oil, observing the different layers that form. To end the lesson, they identify...

In this maps worksheet, learners read 3 pages of detailed information about maps, latitude, longitude, topography, satellites and global positioning. Students then answer 10 questions. There is also a research project assignment available.

Students investigate water as an agent of change. They conduct an experiment involving a mound of soil, observe and record any changes that occur when ice melts on the mound of dirt, and create a drawing of the changes that take place...

Explore Earth and her amazing layers with this lesson on planetary change. Students will research the ways in which Earth's layers cause change. They will complete a "Tectonic Puzzle" and use a worksheet to answer questions about Earth's...

Practice reading comprehension by approaching oceanography through 2 pages of informational text. The text compares the ocean floor to the Grand Canyon to gives students perspective, and gives a brief coverage of the earth's crust and...

Providing an interactive experience, this Jeopardy-style game leads players through a review of scientific concepts. The presentation covers topics such as sound, the Earth's layers, magnetism, and the states of matter. This would be a...

Learners discuss Landsat Satellites and the use of the images they provide as well as the purpose of keeping records of the information from the satellites. The class works in groups to complete a worksheet on short term and long term...

Fourth graders discuss the different interactions of plates and the ways mountains are created.  In this plate tectonics lesson students complete an activity in groups.

Earth Rocks! Explore the many properties and types of rocks, where they come from and how they are formed. This resource presents a simplistic overview of the rock cycle. Tip: Bring in samples of sedimentary, metamorphic, and igneous...

With a piece of plastic here and a piece of plastic there, here a piece, there a piece, everywhere a piece. Teams go on a field trip in order to document the locations and kinds of plastic trash in an area near them. The eighth...

Fifteen detailed pictures and informative captions delve deep into the exploration of stars—their life cycle and importance in the universe. 

Be water wise! Science scholars learn the water cycle on a global scale in part seven of a 13-installment series. The hands-on interactive allows them to explore Earth's water storage, types of precipitation, and the cycling of water...

Fourth graders explore the three layers of the Earth describing the composition, thickness, and temperature of each layer. Layers are compared and contrasted and data unearthed placed into graphic organizers.

Eighth graders identify the different layers of the earth. For this earth science lesson, 8th graders choose a project to do from a given list according to their learning style. They present their finished project in class.

Young scholars are introduced to the process of stratification. Using the internet, they read about the Richard Beene archeological site near San Antonio. Using a map, they color code the different layers present at this site and...
