Grade: 5 Strand: Interrelationships in Earth/Space Systems SOL: 5.6 The student will investigate and understand characteristics of the ocean environment. Key concepts include a) geological characteristics; b) physical characteristics; and c) ecological characteristics. Time: 3-4 weeks 1. Desired Results Enduring Understandings (BIG Ideas) The Earth’s oceans are complex environments. Essential Questions
What are the geological, physical and ecological characteristics of the ocean? How are the features and systems of Earth’s oceans interrelated? How have ocean environments been affected weather related factors? (El Nino, global warming) What characteristics change in the Earth’s oceans? (pressure, salinity, light, temperature, volcanoes, tectonic movements, earthquakes) How do changes in the Earth’s oceans affect the ocean’s ecosystems? How have organisms adapted to the Earth’s ocean environments? Understanding the Standard Essential Knowledge, Skills and Processes Students will: Create and interpret a model of the ocean floor and Important features of the ocean floor near the label and describe each of the major features. continents are the continental shelf, the continental Research and describe the variation in depths associated slope, and the continental rise.

These factors influence the type of life forms that are present at a given depth.

Animal-like plankton are called zooplankton. Plant-like in the Teaching Resources book.

A diversity of animals and plants live in the ocean environment and share limited resources. Water is necessary for life. River waters flow into the oceans. Tides are a basic cycle occurring in nature. Water cycle. Food chains begin with the sun. Animals have life needs and specific physical characteristics.

Throughout the Unit Formative Assessment: • Teacher observation of students engaged in cooperative learning investigations. • KWL • Class created science rubric • Science notebook (questions, summaries, charts, drawings) • Informal assessment through observation of students’ participation in hands-on activities and use of vocabulary in classroom discussions. Summative Assessment: • Test/assessment • Completion of accurate model of ocean floor. • Successful creation of an interpretation of a
marine food web. 3. Learning Plan References to Adopted Materials: Science Fusion – Unit 11 Earth’s Oceans Lesson 1 – “What are the oceans like?” Lesson 2 – “How does ocean water move?” Lesson 3 – “How can you model ocean water?” Lesson 4 – “What are some ocean ecosystems?” Science Fusion – Unit 6 Energy and Ecosystems Lesson 1 – “What are roles of organisms in ecosystems?” (focus on ocean organisms: floating, swimming, ocean floor) Lesson 2 –“How does energy move through ecosystems?” (focus on marine food web) Lesson 3 – “What role do decomposers play?” (focus on decomposers in the ocean)
Suggested Activities: refer to VDOE ESS sample lessons (see websites below) Review Activities: Bingo with related vocabulary Matching – oceanography vocabulary words with their definitions and/or pictures http://www.rockingham.k12.va.us/resources/elementary/5science.htm Outdoor Connections: Stream study: If your school is close to a stream, analyze the water for its dissolved oxygen level and/or its pH level. If you can, also see what types of macro-invertebrates are in a sample of the stream. Arlingtonians for a Clean Environment (ACE) can visit your school to help with this activity. Outdoor Classroom Water source: The same tests can be done as stated in the previous bullet, minus the macro-invertebrates study. Modeling a Wave: In a baby pool, or a very large tub, take students outside to create a model of an ocean wave. What happens if more force is applied? High Tide Demonstration: It is recommend to do outside since it might be a little messy. Of course, this can take place inside too! For directions, please see worksheet attached to this section. 4.
