  1. Living Things 7th Grade Chapter 8 Section 1 Pgs. 214-217

  2. Do Now… • Complete Chapter 8 Preview Activity. • Glue completed worksheet in notebook.

  3. Objectives Students will… • Complete Chapter 8 Preview Activity to become familiar with chapter content • Distinguish between living and nonliving things • Identify what living things need to survive • Get back chapter 20 science test

  4. Organisms • Any living thing is called an organism. • Which of the following would be considered an organism? • Frog • Leech • Rock • Sand • Elephant • Ipod

  5. What are living things like?

  6. How organisms grow • A one-celled organism grows by increasing the size of the cell. • A many-celled organism grows by increasing the number of cells.

  7. Plants vs. Animals pgs. 216-217

  8. For Next Time… • Complete Self-Check questions #1-3 pg. 217 in science notebook • Have test signed by a parent due Monday • http://www.pbslearningmedia.org/resource/tdc02.sci.life.colt.alive/is-it-alive/

  9. How Are Living things classified? 7th Grade Chapter 8 Section 2

  10. Do Now… • Define genus, phylogeny and kingdom on index cards. • Check Self Check questions #1-3 pg. 217

  11. Objectives Students will… • Describe how early scientists classified living things • Explain the system of binomial nomenclature • Demonstrate how to use a dichotomous key

  12. Classification

  13. Classification • Why people use scientific names to classify organisms • 1) Using scientific names helps avoid mistakes • 2) Organisms with similar evolutionary histories are classified together • 3) Scientific names provide descriptive information about a species • 4) Scientific names allow information about organisms to be organized easily and efficiently

  14. Determining the phylogeny of an organism Scientists use… • Similarities in structure • Fossils • Hereditary information • Early stages of development

  15. Classification of Animals Way to Remember Kangaroos Play Cellos, Orangutans Fiddle, Gorillas Sing

  16. Tools for Identifying Organisms • Dichotomous keys are used to identify organisms. • They provide descriptions and illustrations of organisms and information about where an organism lives. • For example—the characteristics used to identify mice in North America • 1) Tail hair 2) Ear Size 3) Tail Length 4) Tail Coloration • What characteristics could you use if you wanted to identify a dog?

  17. Dichotomous Key • Using a Key • Classification of Living Things • http://dnr.wi.gov/org/caer/ce/eek/critter/watercritter/critterindex.htm

  18. For Next Time… • Complete Self-Check Questions #1-3 pg. 220 on loose leaf. • This will be a 5pt HW assignment!

  19. Using a Dichotomous Key and Intro to the Cell Theory 7th Grade

  20. Review Now… • Check Self Check questions #1-3 pg. 220 • Hand in questions

  21. Objectives • Students will… • Describe the development of the cell theory • Practice working with a dichotomous key to identify macro invertebrate life

  22. In the Beginning… • Scientists didn’t know what cells looked like or even that they existed! • In the late 1500s, a Dutch Optometrist created the first microscope by putting 2 magnifying glasses together in a tube.

  23. Scientist Contributions

  24. Partner Pairs • Sean/Greyson • Maddie/Megan • Gabby/Caroline K. • Gabrielle/Anna • Julia/Abby • Caroline H./Rachel • Salvo/Owen • Michael C./Ryan • Jake/Michael S.

  25. EEK! Aquatic Critter Key • http://dnr.wi.gov/org/caer/ce/eek/critter/watercritter/critterindex.htm • (Type in search—Eek Water Critter Key) • With a partner, explore and identify macro invertebrate creatures using a dichotomous key. • Label the creatures on the key.

  26. For Next Time… • Read pgs. 221-225 • Define cell theory, cell walls, cell membrane, cytoplasm and ribosomes
