Fossils and Geologic Time
Students explore the development of the geologic time scale. They examine the major time periods in earth's history. Students discuss the role fossils play in helping us understand history.
Curated OER
The Basics of Earth Science
Students discuss and define the term "scientific theory." They work in small groups to draft an overview of one theory including details about the theory's evidence and significance.

Incorporating 3D Visualizations into Your Classroom
Students make observations through 3-D visualizations. They explore scientific and geologic processes through the use of 3-D pictures.
Curated OER
Are We Falling Apart? Exploding Volcanoes
Students explore how volcanoes are formed, list the parts and characteristics of volcanoes, state the differences in various types of lava, and analyze the volume of ejecta from a volcano.

Rock Eaters of the Gulf of Alaska
Learners compare and contrast the processes of photosynthesis and chemosynthesis. They identify and describe sources of energy used by various organisms for chemosynthesis.
Curated OER
Faulty Movement
Students discover the faults throughout the Earth. They describe the different types of faults and how they are related to earthquakes. They build models of the faults.
Curated OER
Vulcan's Revenge-Volcanoes
Sixth graders research various types of volcanoes. They explore the various emissions that come from them. Offer some explanation why some erupt by "quietly" puring lava, while others blast out chunks of rock and clouds of ash and gases.

The Science Behind Tsunamis
Natural disasters can be teachable moments that create more scientifically literate citizens.
Curated OER
The Rock Cycle
Students study the rock cycle of different types of rock. They arrange cut-outs of the parts of the rock cycle in the correct order and then draw the rock cycle or research different types of rocks.

Volcanoes And Atmospheres
Students identify the volcano as the primary source of atmospheric gases, to explain the formation of ozone, and to recognize the dangers of volcanic gases through the use of technology in the classroom.
Curated OER
Cell Energy-Colorful Respiration
Students examine the acid-base indicator, bromthymol blue (BTB), and what happens to it when you blow air into it or add plants and snails. Through an experiment, they test three different setups of BTB and record the color changes that...
Curated OER
Mount St. Helens Shakes and Burps
Students uncover the nature of volcanoes and locate some of the world's active, dormant, and extinct volcanoes. They also discover how scientists detect, measure, and predict volcanic activity.
Curated OER
Island formation
Learners explain what an island is, and distinguish islands from similar landforms. They compare and contrast the different ways in which islands are formed.
