  1. Is it alive?

  2. Is this alive? • Object 1: Plant

  3. Is this alive? • Object 2: Dried sea stars

  4. Is this alive? • Object 3: Fish

  5. Is this alive? • Object 4: Car http://www.popsci.com/science/article/2013-02/physicists-create-nearly-living-crystals?src=twitter

  6. Biology • bio- life • ology- study of • Biology- study of living things

  7. 5 characteristics of life • Living things are organized. They have cells • Cells are the smallest unit of an organism that can carry on life processes http://www.exploratorium.edu/imaging_station/students/blood_cells.html http://www.exploratorium.edu/imaging_station/students/cell_struct_funct.html

  8. 5 characteristics of life 2. Living things respond to stimuli Nematodes moving around: http://www.exploratorium.edu/imaging_station/students/c_elegans.html Amoeba moving around: http://www.exploratorium.edu/imaging_station/students/cell_motility.html phototropism in plants http://www.youtube.com/watch?v=zctM_TWg5Ik Pinecone closing http://www.youtube.com/watch?v=0GaKFcANjng&feature=related Protozoa moving http://vimeo.com/53807106

  9. 3. Living things use energy • eat food, exchange gases, or absorb sunlight amoeba eating a paramecium http://www.youtube.com/watch?v=aWItglvTiLc

  10. How does this show energy use?

  11. 4. Living things grow and develop. -babies and kids are undeveloped humans Zebra fish development video: http://www.exploratorium.edu/imaging_station/gallery.php?Asset=Zebrafish%20development&Group=&Category=Development&Section=Introduction Sea urchin cell division http://www.exploratorium.edu/imaging_station/gallery.php?Asset=Sea%20urchin%20embryo%20cell%20division&Group=&Category=Mitosis&Section=Introduction Stem cell growth and division http://www.exploratorium.edu/imaging_station/students/stem_cells.html

  12. 5. Living things reproduce • Reproduction can be sexual (offspring are a genetic mix of mom and dad) or asexual (offspring are an exact genetic copy of parent) sea urchin egg fertilization: http://www.exploratorium.edu/imaging_station/students/sea_urchins_fert.html

  13. Is it alive? • A fossil? • A seed? • A virus?

  14. Living or not? Why?

  15. Review: What are the five characteristics of life? • All living things are made of cells or are organized • All living things respond to stimuli • All living things take in and use energy • All living things grow and develop • All living things reproduce

  16. How many different species of living things are on Earth? • The National Science Foundation’s “Tree of Life” project estimates that there could be anywhere from 5 million to 100 million species on the planet, but science has only identified about 2 million.

  17. How do we organize living things? • Living things are organized based on number of cells, type of cells, how they get food, and how they reproduce.

  18. All living things are classified into five different kingdoms • Why we classify living things http://www.youtube.com/watch?v=Q0cIfO4UeZE The five kingdoms intro • http://www.youtube.com/watch?v=TPZSoNY9vAo

  19. Vocabulary foldable • You will make a foldable for 9 vocabulary words • A copy of the words and definitions can be found on my website http://www.cinnaminson.com/Page/1737
