Student Learning Map for Unit: The Foundation of Life in the Ocean (5.3) Key Learning(s): The theory of evolution is connected to the origins of energy and matter. Life began on Earth once the conditions became suitable. Life has the ability to adapt to many different conditions and stresses. There are some basic parameters that scientists use to separate life from non-life. Primary producers are the most important part of any food web. Our classification system is flexible enough to account for exceptions. There is a great diversity of life in the oceans and we are continuing to find new species. Unit Essential Question(s): How did ‘everything’ come into being? Where did life begin? How do we classify the zones of the ocean? What are the characteristics of life? How is energy required for life? How does the processes of photosynthesis and chemosynthesis relate to the concept of primary production? How are animals classified or organized and why is it necessary for humans to classify things? Concept: Concept: Concept: Concept: Prokaryotes – Small Yet Significant Marine Algae and Plants Simplest of all Animals – Sponges, Coral, Anemones, Seafans, and Jellyfish A Little More Complex – Simple Marine Worms, Mollusks, and Complex Worms Lesson Essential Question(s): Lesson Essential Question(s): Lesson Essential Question(s): Lesson Essential Question(s): What are prokaryotes?
