Summary Look at real seeds (outdoors or in) then design wind blown seeds using tissue paper, feathers and other materials. Build a model helicopter seed. Science content Biology: Features, Adaptations of Living Things (K, 1, 3, 7) Biology: Life Cycles (2) Activities in this lesson Seed diversity and classification Flower or apple dissection Seed dissection Wind-blown seed models Seed helicopter paper model Resource How a plant grows Procedure Discussion to introduce seeds. Ideas to bring up: Fall is the time when many plants make seeds. Seeds have protective coatings that allow them to survive the colder winter. They commonly germinate into a plant when the warmer weather returns in the Spring. Seeds are made to spread a plant to new places. The seeds are dispersed to new places where they have their own water and nutrients without competing with the parent plant. Seeds are made in a plant after its flowers have been pollinated. Optional: Seed hunt activity outdoors. Apple dissection (not flower). Open apple. What are these? [Seeds.] Seeds make a new plant. Students can study a bean seed closely.Seed study, both bean and dandelion. Dandelion seed formation: https://upload.wikimedia.org/wikipedia/commons/thumb/f/f6/Loewenzahn_Ta… Timelapse of dandelion seed formation: https://youtu.be/UQ_QqtXoyQw Seeds look different from each other. They are all adapted to spread as far from the parent plant as possible, so that it has its own space to grow.Look at different seeds and discuss how they disperse - by animals or wind. Make your own models of seeds that are blown by the wind.Wind blown seed design activity. You'll design seeds that can catch a wind - wings, parachute, or other structures that make the seed wide but light.Helicopter seed models instead for Ks and lower primaries. Notes Assist Ks individially as necessary. Allow time for Ks and they will stay engaged. Grades taught Gr K Gr 1 Gr 2 Gr 4 Gr 5
