Science SCI.III.2.5 Strand: Using Scientific Knowledge in Life Science - Organization of Living Things Standard: Benchmark: Grade: 3rd All students will analyze how parts of living things are adapted to carry out specific functions Explain functions of selected seed plant parts Constructing and Reflecting: SCI.I.1.1 - Generate reasonable questions about the world based on observation. SCI.I.1.2 - Develop solutions to problems through reasoning, observation, and investigation. SCI.I.1.3 - Manipulate simple devices that aid observation and data collection. SCI.II.1.1 - In the scientific world, decisions must be based on factual evidence that can be replicated. SCI.II.1.2 - Show how science concepts can be illustrated through creative expression such as language arts and fine arts. Vocabulary / Key Concepts Context Plant parts: Common edible plant parts: • • • • • • • • • • • • • roots stems leaves flowers fruits seeds bean cauliflower carrot apple tomato celery spinach Knowledge and Skills Resources Coloma Resources: All plants are made up of parts that perform a specific function (job) to keep the plant alive. Students will explain how each part of a plant that produces seeds works to support a plant’s life. Discover the Wonder (Scott Foresman) – Grade 3 Module B – Chapter 1 • • Photosynthesis poster • • • • roots – anchor the plant and take in water and minerals stem – provides support and carries water, minerals, and food to all parts of the plant leaves – make food (site of food production) flower – produces fruit and attracts pollinators fruit – holds and disperses seeds; protects embryo seeds – carry embryo for a new plant Flower model: Large Geppert flower model “Seed Plants” Sing the Science Standards with the Science Explosion Songbook “Salad Nutrition Chart” Grow Lab Activities for Growing Minds ISBN: 091587332 (NSF Pub.)

Focus Question: What are the functions of seed plant parts? Begin by reading a biography about Katherine Esau. As a review of plant parts and their functions – have children in small groups match a plant part card with the correct definition card (link to benchmark clarification III.2.E.5). Lead class discussion to ensure correct matches. Provide examples of foods that represent each part of a plant: Food Part Function bean seed carries embryo for new plant cauliflower flower produces fruit and attracts pollinators carrots root anchors plant and takes in water and minerals tomatoes fruit holds and disperses seeds; protects embryo spinach leaf makes food (site of food production) celery stem provides support and carries water, minerals and food to all parts of the plant Have students identify each item. In small groups, as food is passed to each group, have students classify each food as either a root, stem, leaf, flower, fruit, or seed. Have groups record their placement on a chart or board visible to everyone. Through class discussion, clarify the part of plant each food represents. Assessment Create a plant part salad. Incorporate each plant part in the salad. Identify the part and the function of each part through a written ‘menu’ entry, a labeled diagram, or an oral presentation about their salad. (Give students rubric before activity.) Scoring Rubric Criteria Apprentice Basic Meets Exceeds Completeness of Creates salad plant parts containing two or three plant parts. Creates salad containing four or five plant parts. Creates salad containing all plant parts. Creates salad containing more than one of each of the plant parts. Identification of plant parts Identifies two or three plant parts. Identifies four or five plant parts. Identifies six plant parts. Identifies six plant parts Functions of plant parts Identifies a function of two or three plant parts. Identifies a function of four or five plant parts. Identifies a function of six plant parts. Identifies more than one of the functions of the six plant parts. Teacher Notes: Analyze how parts of living things are adapted to carry out specific functions. Multicellular organisms, over a long period of time, have adapted and become specialized to be efficient at a particular function...for example the roots, stems, leaves, flowers, fruits, and seeds of a common green plant have specialized parts that work together to form systems to do processes which become interdependent within the organism. This interdependence helps to maintain a stable internal environment in higher plants and animals. This stable environment can be, in turn, disrupted by disease and other environmental conditions. The scientifically literate student should be able to describe how technology can be used in the prevention, diagnosis, and treatment of diseases in today's world.
