Science Worksheets and Study Guides Seventh Grade. Exploring the Oceans/Oceanography

The resources above correspond to the standards listed below:

Washington Standards

WA.4. Earth and Space Science
ES2. Earth Systems, Structures, and Processes
6-8.ES2. Cycles in Earth Systems: In prior grades students learned how Earth materials change and how they can be used for various purposes. In grades 6-8 students learn about planet Earth as an interacting system of solids, liquids, and gases. Solar energy powers the water cycle and drives the weather system and ocean currents. Energy from within the planet drives the rock cycle and moves huge plates on the Earth's surface, causing earthquakes and volcanoes. The landforms we see today result from processes that build up and break down Earth structures. These fundamental ideas will enable students to understand the history of their planet, Earth processes occurring today, and future geologic events.
6-8.ES2D. Water is a solvent. As it passes through the water cycle, it dissolves minerals and gases and carries them to the oceans.
6-8.ES2D.1. Students are expected to distinguish between bodies of saltwater and fresh water and explain how saltwater became salty.
WA.4. Life Science
LS2. Ecosystems
6-8.LS2. Flow of Energy Through Ecosystems: In prior grades students learned how ecosystems change and how these changes affect the capacity of an ecosystem to support populations. In grades 6-8 students learn to apply key concepts about ecosystems to understand the interactions among organisms and the nonliving environment. Essential concepts include the process of photosynthesis used by plants to transform the energy of sunlight into food energy, which is used by other organisms, and possible causes of environmental change. Students also learn to investigate environmental issues and to use science to evaluate different solutions to problems. Knowledge of how energy flows through ecosystems is a critical aspect of students' understanding of how energy sustains life on the planet, including human life.
6-8.LS2A. Students know that an ecosystem consists of all the populations living within a specific area and the nonliving factors they interact with. One geographical area may contain many ecosystems.
6-8.LS2A.2. Students are expected to give examples of ecosystems (e.g., Olympic National Forest, Puget Sound, one square foot of lawn) and describe their boundaries and contents.
