Course Overview

Marine Science 1b: Our Blue Planet is an academically rigorous high school course that continues the study of Earth's aquatic environments, building on the foundation established in Marine Science 1a. This course emphasizes the physical, chemical, and biological dimensions of marine science, with particular focus on oceanography, marine geology, and marine ecology. Students explore the diversity of marine life, examine ecosystems from coral reefs to the deep sea, and evaluate the significant impact of human activities on ocean systems. The curriculum underscores the oceans' critical role in global climate, ecosystems, and human society.

Key Learning Focus

• Marine Ecosystems: Analyzing ecosystems such as coral reefs, estuaries, and the open ocean.
• Marine Organisms: Studying adaptations, biodiversity, and interdependence of marine life forms.
• Oceanography: Investigating currents, tides, waves, and the role of oceans in regulating climate.
• Marine Geology: Examining seafloor features, plate tectonics, and the geological processes shaping oceans.
• Human Impacts: Assessing overfishing, pollution, climate change, and conservation strategies.
• Sustainability and Society: Exploring how oceans influence human activity and how sustainable practices protect marine resources.

Instructional Approach

The course emphasizes active, inquiry-driven learning through project-based activities, lab investigations, and data analysis. Students analyze marine ecosystems, investigate ocean currents, study the behavior of marine species, and evaluate environmental challenges through real-world case studies. Collaborative projects and hands-on explorations encourage critical thinking, strengthen technical and analytical skills, and deepen appreciation for the importance of the oceans in global systems.

Academic Alignment and Progression

Marine Science 1b: Our Blue Planet is aligned with state and national science education standards and is intended for grades 9–12. As the second course in a two-part sequence, it builds directly on Marine Science 1a: Introduction, offering students a comprehensive understanding of marine science. Completion of the course prepares students for college-level study in marine biology, oceanography, environmental science, or related STEM fields, and connects to career clusters in Natural Resources, Environmental Science, and Sustainability.

Outcomes

By the end of Marine Science 1b, students will:

• Demonstrate advanced knowledge of marine biology, oceanography, ecology, and geology.
• Investigate and analyze the role of ocean systems in Earth's climate and human activity.
• Evaluate the impact of human activities on marine ecosystems and propose sustainable solutions.
• Apply scientific inquiry skills through lab work, field studies, and data-driven projects.
• Appreciate the global importance of oceans and their interconnection with life on Earth.
• Be prepared for college-level coursework in marine science, oceanography, and related fields.
