Unit Overview Content Area: Science Unit Title: Oceans Unit: 2 Target Course/Grade Level: Sixth Grade Timeline: 10 weeks Unit Summary This Oceans unit provides a means for students to ascertain the knowledge in the importance of water, the water cycle, fresh water environments, waves, tides, currents, and ocean zones. Each section within the unit leads to the next creating a progression of knowledge. Students will discover the unique characteristics of water, the water cycle and various freshwater environments. Students will then determine that all water leads to the ocean. The ocean section is where students will use manipulatives to explain ocean waves, tides, and currents. Ocean chemistry is also taught which enables students to understand the properties and characteristics of ocean zones. The entire unit culminates with students participating in experiments, group discussions, and projects with the goal of understanding the significance of water which enables life on Earth. Primary interdisciplinary connections: Language Arts, 21st Century Life and Careers, and Technology 21st century themes and skills: A. Critical Thinking and Problem Solving B. Creativity and Innovation, C. Collaboration, Teamwork, and Leadership Unit Rationale “Today more than ever before, science holds the key to our survival as a planet and our security and prosperity as a nation” (Obama, 2008). Earth is known as the “water planet”. Water is not only essential for all living things but for the existence of Earth as a life giving planet. Water shapes the land through erosion; however erosion can also be used to date terrestrial formations that give scientists insight to how the Earth has changed over its billions of years of existence. The ocean covers 71% of Earth’s surface and controls weather phenomenon’s like climate. Its size and power is reason enough to study the ocean. Through learning and awareness students will gain an understanding regarding the characteristics and properties of water and how humans can live economically and environmentally responsible lives. Learning Targets Standards Standard 5.1 Science Practices All students will understand that science is both a body of knowledge and an evidence-based, modelbuilding enterprise that continually extends, refines, and revises knowledge. The four Science Practices strands encompass the knowledge and reasoning skills that students must acquire to be proficient in science. B. Generating Scientific Evidence Through Active Investigations: Students master the conceptual, mathematical, physical, and computational tools that need to be applied when constructing and evaluating claims. C. Reflect on Scientific Knowledge: Scientific knowledge builds on itself over time. D. Participate Productively in Science: The growth of scientific knowledge involves critique and communication, which are social practices that are governed by a core set of values and norms. Standard 5.4 Earth Systems Science All students will understand that Earth operates as a set of complex, dynamic, and interconnected systems, and is a part of the all-encompassing system of the universe. A. Objects in the Universe: Our universe has been expanding and evolving for 13.7 billion years under the influence of gravitational and nuclear forces. As gravity governs its expansion, organizational patterns, and the movement of celestial bodies, nuclear forces within stars govern its evolution through the processes of stellar birth and death. These same processes governed the formation of our solar system 4.6 billion years ago. B. History of Earth: From the time that Earth formed from a nebula 4.6 billion years ago, it has been evolving as a result of geologic, biological, physical, and chemical processes. E. Energy in Earth Systems: Internal and external sources of energy drive Earth systems. F. Climate and Weather: Earth’s weather and climate systems are the result of complex interactions between land, ocean, ice, and atmosphere. G. Biogeochemical Cycles: The biogeochemical cycles in the Earth systems include the flow of microscopic and macroscopic resources from one reservoir in the hydrosphere, geosphere, atmosphere, or biosphere to another, are driven by Earth's internal and external sources of energy, and are impacted by human activity. Standard 9.1 21st-Century Life & Career Skills All students will demonstrate the creative, critical thinking, collaboration, and problem-solving skills needed to function successfully as both global citizens and workers in diverse ethnic and organizational cultures. Content Statements: Related Content Statements for Standard 5.1 Mathematics and technology are used to gather, analyze, and communicate results. Carefully collected evidence is used to construct and defend arguments. Scientific reasoning is used to support scientific conclusions. Scientific models and understandings of fundamental concepts and principles are refined as new evidence is considered. Science involves practicing productive social interactions with peers, such as partner talk, wholegroup discussions, and small-group work. Related Content Statements for Standard 5.2 Sinking and floating can be predicted using forces that depend on the relative densities of objects and materials. Related Content Statements for Standard 5.4 The relative positions and motions of the Sun, Earth, and Moon result in the phases of the Moon, eclipses, and the daily and monthly cycle of tides. Moving water, wind, and ice continually shape Earth’s surface by eroding rock and soil in some areas and depositing them in other areas. Erosion plays an important role in the formation of soil, but too much erosion can wash away fertile soil from ecosystems, including farms. The Sun is the major source of energy for circulating the atmosphere and oceans. The Sun provides energy for plants to grow and drives convection within the atmosphere and oceans, producing winds, ocean currents, and the water cycle. Climate is influenced locally and globally by atmospheric interactions with land masses and bodies of water. Circulation of water in marine environments is dependent on factors such as the composition of water masses and energy from the Sun or wind. Related Content Statement for Standard 9.1 The ability to recognize a problem and apply critical thinking and problem-solving skills to solve the problem is a lifelong skill that develops over time. Gathering and evaluating knowledge and information from a variety of sources, including global perspectives, fosters creativity and innovative thinking. Collaboration and teamwork enable individuals or groups to achieve common goals with greater efficiency. Leadership abilities develop over time through participation in groups and/or teams that are engaged in challenging or competitive activities.

Unit Essential Questions Unit Enduring Understandings Why is water important? Water is a unique compound with properties that differ from familiar substances. Water is a polar How does the sun play a key role in the water substance which enables it to have a high surface cycle? tension, perform capillary action, be the universal What are some characteristics of different solvent, form easily into 3 states, and also have a freshwater environments and where does all high specific heat. The Earth’s surface is 71% freshwater lead? covered by water. Water is essential for life. What causes waves, tides, and currents? What are the various features of the ocean? How do we build and refine models that describe and explain the natural and designed world? What constitutes useful scientific evidence? The sun is what drives the water cycle. The sun causes the water to evaporate, this leads to condensation and cloud formation, which causes precipitation that eventually forms bodies of water or erosion from runoff. Whether water is located in a lake, stream, river, glacier or aquifer, all water ultimately ends up in the ocean. The natural and human-based activities that occur on land can greatly impact the ocean environment. The sun causes wind which in-turn creates waves. Tides are caused by the gravitational pull between the Earth, Sun, and Moon. Surface currents originate and move based on wind while deep currents are caused by differences in density. Technology has given us the ability to “see” the various features of the ocean including the ocean floor and ocean zones. From underwater mountains and volcanoes to deep ocean trenches, there is much of the ocean that has yet to be discovered. Measurement and observation tools are used to categorize, represent and interpret the natural world. Evidence is used for building, refining, and/or critiquing scientific explanations.
