About This Course
Utilize the chapters in our middle school earth science course to learn about the Earth's structure and important physical characteristics. Chapters explore the processes that cause earthquakes, volcanoes, mountains and rock formations. You'll also learn about different types of energies and their roles in the earth system. Chapters are devoted to the scientific method and the interpretation of data. The topics explored during the course include:
- The four spheres of the earth and their structure
- Causes of plate movement, earthquakes and volcanoes
- Formation of mountains, rock formations, beaches, valleys and rivers
- Forms of thermal, tidal, solar and nuclear energy in the earth system
- Ecosystems, habitats, niches and biomes
- Material resources, including water, soil and minerals
- Scientific method and other forms of earth science investigation and experimentation
Our earth science chapters are presented through a series of concise video lessons that include important vocabulary and key terms. You can access transcripts for all chapter lessons to better understand the content, and quizzes are provided to test your learning of the material.
|Earth's Spheres and Structure||These lessons name the internal and external forces that shape the earth's surface and discuss the relationships between the earth's four spheres. You'll also learn about the nature and composition of the earth's crust, mantle and core.|
|Plate Tectonics||The lessons define the theory of Pangaea, the theory of continental drift and the unified theory for change of the earth's surface. You'll be able to identify the causes of tectonic plate movement and understand convergent, divergent and transform boundaries.|
|Understanding Earthquakes||Get information on the components and causes of earthquakes. You'll be able to understand aftershocks and foreshocks of an earthquake, as well as the destruction that may come from this natural phenomenon. The lessons also show how the Richter scale can be used to measure earthquake activity.|
|Understanding Volcanoes||By the end of these lessons, you'll be able to list the types of volcanoes, including shield, cinder cones and composite cones. You'll also learn about the gases released and their flow and effects during a volcanic eruption.|
|Understanding Rock Deformation and Mountain Building||The lessons help you understand the causes and types of rock deformation. Review the different types of geological folds and faults. Video lessons explore the process of mountain building.|
|Shaping the Earth's Surface||After finishing the lessons, you'll be able to explain the effect of erosion and deposition on landforms and the earth's topography. Lessons show how valleys, shorelines, beaches, rivers and streams are formed. You'll also identify how natural events can change habitats.|
|Thermal Energy||These lessons provide examples of thermal energy and explain how fuel becomes heat energy. You'll study the transformation and transfer of energy to living organisms.|
|Energy in the Earth System||Lessons show how the sun serves as a source of energy for winds, currents and the water cycle. You'll learn the difference between weather and climate. You can also explore different weather variables, including air pressure, temperature and density.|
|Ecology and Ecosystems||Lessons depict the flow of energy in an ecosystem through the food chain and trophic levels. You'll study the interactions between different populations of species, such as predator/prey relationships, competition and symbiotic relationships. Lessons highlight the defining characteristics of the earth's various biomes. You'll be able to explain how the phosphorous, nitrogen and carbon cycles work.|
|Earth's Energy Resources||These lessons provide examples of renewable and non-renewable resources. You'll analyze the advantages and disadvantages of fossil fuels and explore different forms of energy, such as nuclear, oil, natural gas, solar, wind, hydropower and geothermal energies.|
|Earth's Material Resources||By the end of the lessons, you'll be able to name the unique properties of water and important water resource issues. You'll also review the steps of the rock cycle and the three major rock groups.|
|Earth Science Investigation and Experimentation||These lessons give you the tools to understand and list the steps of the scientific method. You'll be able to successfully read and construct graphs, charts and tables from scientific data. You'll also learn to provide written and oral reports of scientific investigation findings.|
