Please keep your work neat and presentable! Rational: At the end of each unit students will be responsible for completing a culminating task that provides evidence they have internalized the concepts and content of the given unit. Strand 4: Culminating Task: Students will create a model of either a plant or animal cell from materials of their choosing. The following information needs to be included in their model. > A representation of each organelle > A legend system connecting the identified organelle with a detailed description of its functions. > Cell model needs to follow a general sense of scale. For instance the nucleus should not take up 50% of the model.
Concept 1: Structure and Function in Living Systems Understand the relationships between structures and functions of organisms.
PO 1. Explain the importance of water to organisms.
PO 2. Describe the basic structure of a cell, including: • cell wall • cell membrane • nucleus
PO 4. Differentiate between plant and animal cells.
PO 5. Explain the hierarchy of cells, tissues, organs, and systems.
PO 6. Relate the following structures of living organisms to their functions: Animals • respiration – gills, lungs • digestion – stomach, intestines • circulation – heart, veins, arteries, capillaries • locomotion – muscles, skeleton Plants • transpiration – stomata, roots, xylem, phloem • absorption – roots, xylem, phloem response to stimulus (phototropism, hydrotropism, geotropism) – roots, xylem, phloem
PO 7. Describe how the various systems of living organisms work together to perform a vital function: • respiratory and circulatory • muscular and skeletal • digestive and excretory
Cell Membrane Lab
Watch Preview video and setup science notebook for lab. Watch at least 3 of the research videos and take around a paragraph of notes on what the cell membrane is and use those notes to help construct a hypothesis in class.
Concept 2: Reproduction and Heredity Understand the basic principles of heredity
No performance objectives at this grade level however, I love genetics and if we have time we will delve into this area of life science to better understand the other components that you are responsible for understanding.
Concept 3: Populations of Organisms in an Ecosystem Analyze the relationships among various organisms and their environment.
PO 1. Explain that sunlight is the major source of energy for most ecosystems. (See Strand 5 Concept 3 and Strand 6 Concept 2
PO 2. Describe how the following environmental conditions affect the quality of life: • water quality • climate • population density • smog
Concept 4: Diversity, Adaptation, and Behavior Identify structural and behavioral adaptations.
No performance objectives at this grade level however, this directly links to genetics and if we have time we will delve into this area of life science to better understand the other components that you are responsible for understanding.
