Living Systems Storyline

1 Living s Storyline Prepared Graduate Competency Analyze how various organisms grow, develop, and differentiate during their lifetimes based on an interplay between genetics and their environment. Analyze the relationship between structure and function in living systems at a variety of organizational levels, and recognize living systems' dependence on natural selection. Big Ideas All organisms have structures and systems with separate functions. Human body systems have basic structures, functions, and needs. Enduring Understandings and Grade Level Expectations Living things are part of large systems called ecosystems. Living things have body systems that include structures to help them survive in their ecosystem. All living things need food, water, a way to dispose of waste, and an environment in which they can live. Animals (including humans) detect, process, and use information about their environment to survive. Organisms and populations of organisms depend on their environmental interactions both with other living things and with nonliving factors. Essential Questions How do organisms live, grow, and respond to their environment? How and why do organisms interact with their environment and what are the effects of those interactions?

2 1: s Everyday s The Earth Recycling How can you identify a system? Is planet Earth a system? What happens when compost worms interact with organic litter? 1 A system is a collection of interacting objects, ideas, and/or procedures that together define a physical entity or process. A subsystem is a small system that is inside a larger system. Earth can be described as the interaction of four earth systems: the rocky part (geosphere), the atmosphere, the water (hydrosphere), and the complexity of living organisms (biosphere). Food webs are subsystems within ecosystems. They describe the transfer of matter and energy within the system. Food webs are made up of producers (organisms that make up their own food), consumers (organisms that eat other organisms to obtain food), and decomposers (organisms that consume and recycle dead organisms and organic waste). Food webs are made up of producers, consumers, and decomposers. Introduction to s Is Earth a? The Biosphere Nature s Recycling

3 2: Nutrient s Yeast Nutrition Plant Nutrition 7 Days Animal Nutrition 2 days What does yeast need to break its dormancy? How do plants get the food they need? How do animals get the nutrients they need? 2 Yeast is a single-celled fungus. Dormant yeast cells can become active again when provided with water, warmth, and sugar as a food source. Carbon dioxide is a waste byproduct of yeast metabolism. A nutrient is a substance, such as sugar or starch, that is used by a cell to produce the energy needed to perform the functions of life. Plants make their own food by photosynthesis. Chlorophyll is the green pigment that absorbs sunlight in the cells of producer organisms. Green plant cells make sugar (food) from carbon dioxide and water in the presence of sunlight, and release oxygen. Animals obtain nutrients by eating other organisms. Digestion is the process used by animals to break down complex food items into simple nutrients. There s Yeast in my Bread! Producers Getting Nutrients The Human Digestive

4 3: Transport s Plant Vascular s Two session- then Circulatory s Respiratory s How are nutrients transported to cells in a plant? How do humans transport nutrients to all their cells? Why do people breathe? 3 Scientists classify objects and information by organizing them into groups with similar attributes. Vascular bundles are arranged in predictable patterns of veins in the leaves of vascular plants. Vascular plants have specialized tissues for the transport of water, minerals, and sugar to cells: xylem tubes carry water and minerals from the plant s roots to all the cells in a one-way flow; phloem tubes carry sugar from the leaves to all the cells that need it. Leaf Classification Plant Vascular s The Story of Maple Syrup All cells have basic needs: water, food, gas exchange, and waste disposable. Multicellular organisms have systems for transporting nutrients and wastes. In the human circulatory system, blood transports resources to the cells and wastes from the cells. The Human Circulatory In humans, the respiratory system transports oxygen to the blood and carbon dioxide from the blood. All cells have basic needs; water, food, gas exchange, and waste disposal. Multicellular organisms have systems for transporting nutrients and wastes. The Human Respiratory Other Circulatory and Respiratory s

5 4: Sensory s Stimulus/ Response Attention Sound Off 1 Day Part Four: Instinct and Learning 2 days Part Five: Ecosystems 3 days In dodge ball, how are you able to avoid being hit? What features of organisms attract attention? How do animals use their sense of hearing? What behaviors are instinctive, and what behaviors are learned? What are the parts of a marine ecosystem? Summative 4 A stimulus is something that triggers a response. A stimulus is often information received through the senses. A response is a reaction of a living thing to a stimulus. Response time is the length of time it takes for a person to respond to a stimulus. Animal adaptations include pattern and color that attract attention to warn predators off or to attract a mate. Animals communicate to warn others of danger, scare predators away, or locate others of their kind, including family members. Instinctive behaviors, such as knowing what to eat, how to find shelter, and how to migrate, help organisms survive. Some animals learn behaviors by watching adults or through trial and error. Marine ecosystems have biotic (living) and abiotic (nonliving) parts. Phytoplankton are the base of the food chain in the ocean. The ocean plays an important role in the carbon cycle.
