The Tiny Seed by Eric Carle (1987) Science-Literacy Teacher Guide Major themes for this book the needs and differences of seeds and plants: Survival – Living things have structures and behaviors the help them get what they need (seed mobility, sprouting, plant growth). Ecosystem – Nonliving and other living things can help or threaten survival. Life Cycle – There are differences among offspring that can help or hurt their survival. Science Standards (EALR 4): LS1 – Living Systems LS2 – Ecosystems LS3 – Biological Evolution 1st: Use after FOSS Air & Weather LS1F – Explain that most plants get water through roots and gather light through leaves. LS2B – Describe how the habitat provides the basic needs of living things living there. LS3A – Use logical rules to sort objects into “living” and “not living.” LS3C – Use external features & behaviors of animals to compare or sort them into groups. 2-3: LS1A – Describe the life cycle of a common animal. [Going from one generation to another]. LS2A – Identify 4 ways that an ecosystem supports the basic needs of living things that live there. LS3A – Give examples of variations among individuals in a population (e.g. coloration, size). LS3B – Compare features of offspring that resemble parents, and features that are different. LS3C – Predict how differences might help an individual plant/animal survive better than another. 4th: Use anytime in 4th grade struggle for survival LS1C – Give example of how a plant or animal responds to its environment. LS2A – Identify the living and nonliving parts of an ecosystem. LS2B – Explain that plants make their food, while animals get food by eating plants or animals. LS2E – Describe how one population may affect another (plant or animal) in the ecosystem. LS3A – List reasons why some populations in an ecosystem may not do as well as others. LS3B – Explain that living things inherit (from parents) characteristics that allow them to survive. 6th: Use with FOSS Environments The Tiny Seed by Eric Carle (1987) Science-Literacy Teacher Guide Pre-Reading 1. Reveal students’ initial ideas about seeds and their needs: “A flower makes many seeds. What helps some seeds to become plants, but other seeds not to become plants?” 2. Collect & chart students’ ideas. Probe them for how they know (or think they know) these things. Our Ideas about Seeds Becoming Plants I Know I Think I Know How I Know (or think I know) Questions We Have About SeedsPlants Needs of Sprouting Seeds: 3. Collect and chart questions that students have about the needs and differences of seeds and plants … especially in these categories: Needs of Growing Plants: Differences among Plants: Post-Reading 1. Guide student discussion add/change their initial ideas; answer their questions: “What did the story add to what we know about seeds becoming plants?” “Which of our questions got answered?” 2. Collect and chart new questions that students have about the needs and differences of seeds and plants…same 3 categories as before. 3. Use online research to address student questions: (text + pictures) Alfalfa seed/plant growth http://www.ag.ndsu.edu/pubs/plantsci/hay/r648w.htm (video) Plants germinating in light & dark http://plantsinmotion.bio.indiana.edu/plantmotion/earlygrowth/germination/arabidopsis/atgermination.html 4th grade (online simulations & Concord Consortium) Virtual Field http://www.concord.org/activities/virtual-field Literacy Strategies Finding evidence in the story that supports or challenges students’ initial ideas. The Tiny Seed by Eric Carle (1987) Science-Literacy Teacher Guide About Seeds—Information Found in the Story: [ + questions to follow up each fact about seeds ] In the text and pictures… Wind blows seeds far away. [How does this help the flower?] Seeds are different sizes. [How many seeds are there? How does big/small seed size help the plant?] Some seeds don’t survive/sprout. [Why are there so many seeds?] Seeds don’t sprout right away. [How long can a seed wait?] Rain helps seeds sprout. [How does water get inside?] Seeds first develop roots, then stems. [Why do roots grow first?] Plants need sunlight, air, rain. [Do seeds need soil? Why/not?] Young plants take sunlight and rain from other plants. Young plants get trampled. [Why does a plant die (or not) when trampled?] Plants get harvested. [What do we get from plants?] Plants look different from each other as they grow. [Why do some plants look different?] Plants grow many times larger than their seed size. [How do plants get bigger?] Petals and leaves fall off of the plant. [What happens to dead plants?] Seeds are formed from one plant for the next generation (offspring). [Which living things have life cycles?] Other Questions: 1. 2. 3. 4. 5. [Are seeds “alive?”] [What do seeds need to survive? To sprout?] [If a seed/plant can die in so many ways, how can they survive on the Earth year after year?] [If plants make so many seeds, how come we don’t see more plants?] [What do we mean by “life cycle?”] Online Resources about Seeds, Plant Growth & Survival: 1.
