Teacher: Taylor, Parris, LaPorte Grade Level: 5th Date SOL/ Learning Objectives 5.6 a-c; 5.1 (ongoing throughout the year) Interrelationships: Ocean Environments Essential Questions & Understandings/ Big Ideas Dates: February 9-13, 2015 Content or Unit: Science Monday 2/9/2015 Tuesday 2/10/2015 Wednesday 2/11/2015 The student will: ~Explore the difference between ocean water and fresh water ~Understand that oceans have many valuable resources ~Understand what causes currents, waves, and tides ~Describe the topography of the ocean floor The student will: ~Explore the difference between ocean water and fresh water ~Understand that oceans have many valuable resources ~Understand what causes currents, waves, and tides ~Describe the topography of the ocean floor The student will: ~Explore the difference between ocean water and fresh water ~Understand that oceans have many valuable resources ~Understand what causes currents, waves, and tides ~Describe the topography of the ocean floor The student will: ~Explore the difference between ocean water and fresh water ~Understand that oceans have many valuable resources ~Understand what causes currents, waves, and tides ~Describe the topography of the ocean floor How does the ocean serve a useful purpose? What are oceans, seas, and basins? How does the water in a wave move? What are tides/ currents? What is the ocean floor like? How do we explore the oceans? How do people affect the oceans? Friday 2/13/2015 Scientists can compare changes in sediment type, organisms found in each layer, and gases trapped in sediment to understand how oceans have changed over time. Ninety-seven percent of Earth’s water comes from the ocean. Oceans are an important natural resource. Key Vocabulary Basin, current, continental shelf, continental slope, continental rise, abyssal plain, seamount, trench Basin, current, continental shelf, continental slope, continental rise, abyssal plain, seamount, trench Assessment Part 1 What are some of the ocean resources you use? How would you describe what you know about the way ocean water moves? 1 Thursday 2/12/2015 Basin, current, continental shelf, continental slope, continental rise, abyssal plain, seamount, trench Basin, current, continental shelf, continental slope, continental rise, abyssal plain, seamount, trench What part of the ocean can be explored from scuba diving? Teacher: Taylor, Parris, LaPorte Grade Level: 5th Possible misconceptions or learning gaps Students may not understand why the oceans do not continue to get saltier. What is the difference between a sea and ocean? Dates: February 9-13, 2015 Content or Unit: Science What causes the ocean water to have different colors? How does the moon affect the tides? How does salt affect water density? Why do continents not end at the seashore? Students may not understand how continental crust merges with ocean crust along the continental rise. Many students may not know the multiple ways in which humans affect the ocean and how our everyday carbon footprint affects the environment negatively. Snapshot/ Warm-up Whole Group Teaching/ Learning Teaching Station 2 What do we use from the ocean in our daily lives? The teacher will explain how salt in water comes from rocks, from within the Earth, and is removed as fast as it is added. Seawater is an important source of minerals. List from the densest to the least dense: vinegar, water, oil, coin TTW explain how areas on Earth within the bulges of water experience high tides and low tides on the outside of those bulges. Bulges occur on the side of the Earth nearest the Moon and on the side opposite. High tide bulges draw the water away from the other areas of the Earth, resulting in low tide. Winds drive surface currents, flowing What causes the tides? Where do continents end? Draw your answer. TTW explain that the sediment that forms the continental rise comes from the continents and the continental shelf. TTW develop vocabulary by asking students to use clues about the vocabulary to determine its meaning. TTW discuss the features of the ocean floor including the continental shelf, slope, and rise; the flat abyssal plains; seamounts; The oceans provide fish and other seafood for us to eat; they contain minerals; they provide a habitat for many organisms; they have recreational use. The dumping of sewage, factory wastes, and fertilizers (farms) pollute the ocean daily. Oil spills are caused by ships carrying oil that break open in the ocean. We can help reduce the Teacher: Taylor, Parris, LaPorte Grade Level: 5th Dates: February 9-13, 2015 Content or Unit: Science clockwise from the equator northward and counterclockwise from the equator southward. trenches; and the midocean ridge. Tell Students that we draw conclusions every day based on facts we receive. Ask students to list three facts from page C 89 and to draw a conclusion about why the lowest tides occur when they do *No Teacher Station Teacher and students will create foldables defining words and pictures/examples of the parts of the ocean floor Activities ~ Work stations *Reinforcing Skill of the Day * Using various liquids of different densities such as water, cooking oil, vinegar, ice, and a coin. Pour the liquids gently into a glass so that they form layers. Drop the coin into the glass as students watch. Float the ice cube on top. TTW ask which is the densest? Least dense? (coin; ice) TTW ask why the liquids do not mix (different densities) 3 *High tides occur on two sides of Earth where the water bulges. The lowest low tides occur at the same time as the highest high tides. The spring tide drawing shows water pulled away from the area of Earth between the bulges. The conclusion is that the bulges are largest during spring tide resulting in the most water.* negative impact by limiting use of harmful fertilizers (that have phosphates and nitrogen), rely less on offshore sources of oil and natural gas, and by not eating endangered fish *No Teacher Station Students will complete an informal assessment in which they make a picture for each of the three major ways in which the ocean’s water moves. For example, for tides, they can draw the tidal bulges on Earth or show a seashore where the water’s edge has moved down the beach.

Create class drawing of the experiment. Where do the highest What are the different high tides and lowest parts of the ocean floor? low tides occur. Explain. How are they similar to land? What is the relationship humans have with the ocean? Why is fresh water less dense than the ocean? What is a current? Draw a picture showing how we affect the ocean.
