Subject: Science Grade Level/Course: 8th Unit Title: The Mysteries of Life Big Idea/Theme: Systems, Order, and Organization Timeframe Needed for Completion: Grading Period: 2nd and 4th Learning Targets: By the end of this unit, students will be able to identify living organisms and life functions, from cells to plants to humans, and how the environment and hereditary factors impact the evolution, reproduction, and survival of organisms. Essential Questions: Curriculum Goals/Objectives: Why do we need to know about cells? How will this knowledge impact my own life? 7.L.1.1 Compare the structures and life functions of single-celled organisms that carry out all of the basic functions of life including: Euglena Amoeba Paramecium Volvox 7.L.1.2 Compare the structures and functions of plant and animal cells, including major organelles (cell membrane, cell wall, nucleus, chloroplasts, mitochondria, and vacuoles). 7.L.1.3 Summarize the hierarchical organization of multi-cellular organisms from cells to tissues to organs to systems to organisms. 7.L.1.4 Summarize the general functions of the major systems of the human body (digestion, respiration, reproduction, circulation, and excretion) and ways that these systems interact with each other to sustain life. 7.L.2.1 Explain why offspring that result from sexual reproduction (fertilization and meiosis) have greater variation than offspring that result from asexual reproduction (budding and mitosis). 7.L.2.2 Infer patterns of heredity using information from Punnett squares and pedigree analysis. 7.L.2.3 Explain the impact of the environment and lifestyle choices on biological inheritance (to include common genetic diseases) and survival. 7. 7.E.1.6 Conclude that the good health of humans requires: monitoring the atmosphere, maintaining air quality and stewardship. Has man changed from the time of cavemen until now? Do other organisms need the same things we need to live and survive? How is the reproduction of a cell similar and different from the way humans reproduce or make babies? What is the difference between sexual reproduction and asexual reproduction? What would happen to living organisms in the event of a major catastrophe like a nuclear explosion? Essential Vocabulary: Literacy and other Integration Opportunities: Assessment Tasks:
