    3. 3. Life Science Goals in Early Childhood Childs Curiosity Free Exploration and Play Lisa Elliott 4/07 Teacher Interaction Through Focused Exploration Organisms Habitats Nature Encourage Deeper Thinking through Questioning and Focused Exploration Reflect, Represent, Discuss, Demonstrate Experiences Model Respect for Living Things

    5. 9. Activity 1 K-W-L Chart What I Learned Want to Know What I Know
    6. 10. Earthworms - What do earthworms eat? -Where do they live? -What do they like? -How do they breathe underground? -Are alive -Live underground What I Learned Want to Know What I Know
    7. 11. Activity 2 <ul><li>Our role as teachers in life science is to guide and encourage further exploration. </li></ul><ul><li>The art of inquiry and constructivist teaching is to not tell or fill a child with facts, but to help each child build and construct their own ideas about the world around them. </li></ul><ul><li>Teachers can do this with through anticipating questions and misconceptions through careful preparation of the learning environment. </li></ul><ul><li>Professional development </li></ul>
    8. 12. Basic Understanding of Life Science Organisms <ul><li>Consist of cells and tissue (14.07) </li></ul><ul><li>Have a life span. (21.54) </li></ul><ul><li>Get energy from another source. (29.05) </li></ul><ul><li>Respond to changes in their environment. (40.58) </li></ul><ul><li>Reproduce and pass their DNA on to the next generation. (49.17) </li></ul>Essential Life Science for Teachers VOD
    9. 13. An Earthworm’s Body <ul><li>Is soft, slimy brown or pink and is divided into rings or segments. </li></ul><ul><li>Is pointed at both ends with one end flattened. </li></ul><ul><li>Uses its skin to breathe and small bristles to move. </li></ul><ul><li>Has no eyes. </li></ul>
    10. 14. Earthworms have a Lifespan <ul><li>Living Beginning </li></ul><ul><li>Growth </li></ul><ul><li>Development </li></ul><ul><li>Reproduction </li></ul><ul><li>Death </li></ul>
    11. 15. Earthworms Get Energy and Matter by Consuming <ul><li>soil, sand or mud as they tunnel through it.  </li></ul><ul><li>dead leaves and other bits of plants. </li></ul>
    12. 16. Earthworms Respond to the Environment by <ul><li>Living underground in burrows for protection. </li></ul><ul><li>Earthworms cover the burrow openings with sticks, leaves or mud to keep out the cold and rain and to stop the burrow from drying out in hot weather. </li></ul><ul><li>Earthworms leave their burrows when they flood with rain. </li></ul>
    13. 17. Protection from Enemies <ul><li>frogs </li></ul><ul><li>birds </li></ul><ul><li>people </li></ul>
    14. 18. Earthworms Movement <ul><li>It has tiny little hairs sticking out underneath its body. The earthworm uses these bristles called setae to cling to the ground as it moves. </li></ul><ul><li>The earthworm contracts its body to move. </li></ul>
    15. 19. Earthworms help the Environment by enriching and producing soil <ul><li>Worms spend their days tunneling through soil. Worms usually tunnel at least 20cm everyday. </li></ul><ul><li>Worms eat dirt and </li></ul><ul><li>other debris. </li></ul><ul><li>Earthworms build soil by producing body waste called castings that are rich in nutrients. </li></ul>
    16. 20. An Earthworms Lifecycle <ul><li>Earthworms are hermaphrodites, each having both female and male reproductive organs. Fertilized eggs are deposited in the soil in cocoons. Each cocoon produces an average of four eggs. Eggs hatch within three weeks. Earthworms burrow deep into the soil and come to the surface to feed on organic debris. </li></ul>
    17. 21. Five Reasons Why Study Earthworms? <ul><li>Young children construct knowledge through participation with others in activities that foster experimentation, problem solving, and social interaction (Gallas 1995; Chaille & Britain 1997). </li></ul><ul><li>Young children should be allowed to exercise choice in the learning environment (Bredekamp & Copple 1997). </li></ul><ul><li>Children’s social skills develop best when they have opportunities to learn and practice them in the context of meaningful activities (e.g., Katz & McClellan 1997). </li></ul><ul><li>Volcanoes made of baking soda and vinegar are a chemistry experiment. </li></ul><ul><li>I had difficulty capturing penguins in my neighborhood. </li></ul>Journal Article NAEYC Young Children and Science; Science in the Preschool Classroom (Conezio &French 2003).
    18. 22. Best Practice for Science/Math <ul><li>Research Based </li></ul><ul><li>Uses Inquiry Methods </li></ul><ul><li>K-W-L Charts to guide, develop and answer questions together. </li></ul><ul><li>Use of Higher Vocabulary and Scaffolding. </li></ul><ul><li>NCTM Guidelines to align to standards. </li></ul><ul><li>Well prepared teachers. </li></ul>
    19. 23. Science Exploration through Play <ul><li>Look for living things. </li></ul><ul><li>Examine where living things live. </li></ul><ul><li>Find out about environments of living things.* </li></ul>
    20. 24. Teacher’s Role <ul><li>Spend time with students who are ready and interested. </li></ul><ul><li>Have ready children engage reluctant children. </li></ul><ul><li>Observe play and listen to discussions to guide, plan, and prepare activities. * </li></ul>
    21. 25. Plan the Environment <ul><li>Child Centered and Teacher Focused. </li></ul><ul><li>Create a Science Rich Environment. </li></ul><ul><li>Encourage Wonder. </li></ul><ul><li>Build Excitement. </li></ul><ul><li>Explore living things in a new way.* </li></ul>
    22. 26. Being a Caring Naturalist <ul><li>What is a Naturalist. </li></ul><ul><li>Stay Safe (discuss what can be touched and what cannot). </li></ul><ul><li>Keep animals and plants safe. </li></ul><ul><li>Look very carefully at what you find.* </li></ul>
    23. 27. Questioning <ul><li>Tell me what you found. </li></ul><ul><li>What does it look like? </li></ul><ul><li>How does it feel? </li></ul><ul><li>Where did you find it? </li></ul><ul><li>Why do you think it was there?* </li></ul>
    24. 28. Reflection <ul><li>Document </li></ul><ul><li>Tally </li></ul><ul><li>Take photographs </li></ul><ul><li>Write more questions* </li></ul>
