  2. Wednesday April 9th 2014 • Welcome! • Take out your review packet and pick up your practice test from the front counter. • Review your test and work on making sure your self- assessment (yellow page) is complete.

  3. Crust and mantle…….. • How far is it from the surface to the center of the earth? • 6371km • The Earth’s crust is _________ km thick. • 100 or 5-70km • The inner core is made from iron and ________. • Nickle • The plastic-like layer of the Earth is called the ___________. • Mantle/ Asthenosphere • The innermost layer of the Earth is the ____________. • Inner Core

  4. Day 2- Ecosystems, Natural Selection and Natural Resources

  5. Living things on Earth interact.

  6. Kingdoms of Life • Open to page 7 in your review packet

  7. Kingdoms of Life • How do we classify life? • The number of cells • The type of nucleus in their cells • How they eat Unicellular has only one cell per being Example- Archaea, Bacteria, Protista Multicellular has many cells per being Example- Fungi, Plantae, Animalia

  8. Kingdoms of Life • Prokaryotic = no membrane around the nucleus • Example- Archaea, Bacteria • Eukaryotic= do have a membrane around the nucleus • Example- Protista, Fungi, Plantae, Animalia • Autotroph= can make their own food • Example- Archaea, Bacteria, Protista, Plantae • Heterotroph= must get there food from others -Example- Bacteria, Protista, Fungi, Animalia

  9. Kingdoms of Life • If you were asked to classify an organism that is multicellular and autotrophic, in which Kingdom might you place it? • Plantae

  10. Kingdoms of Life • If your mystery organism is unicellular and prokaryotic, into which two Kingdoms might you place it? • Archaea or Bacteria

  11. Kingdoms of Life • If the mystery organism is multicellular, eukaryotic and heterotrophic, it could belong to which twoKingdoms? • Fungi and animalia

  12. Types of Plants and Animals * Monocot= grass (means 1 leaf) • Dicot= most everything else (means at least 2 leaves)

  13. Types of Plants and Animals • Conifer = reproduces with seeds in cones, usually has needles, usually green all year.

  14. Types of Plants and Animals • Deciduous- has leaves that usually change color and fall during autumn; reproduces with seeds, fruit and flowers.

  15. Types of Plants and Animals • Arthropods= animals with jointed legs and exoskeletons.

  16. Types of Plants and Animals • Reptiles= reproduce by laying eggs, are covered in scaly skin, and are cold- blooded.

  17. Types of Plants and Animals • Birds= reproduce by laying eggs, have feathers, many can fly, cold blooded.

  18. Types of Plants and Animals • Amphibians = reproduce by laying eggs, can live on land and in the water, go through metamorphosis.

  19. Types of Plants and Animals • Mammals- reproduce with live births, are covered in hair, warm blooded.

  20. Types of Plants and Animals • Fish- have scales, bones, gills, and are cold blooded.

  21. Ecosystems • An ecosystem is a community of living organisms.

  22. Ecosystems provide resources. • All life needs….. • Food • Shelter • Water • Space ….to survive.

  23. Natural Resources • Are materials we use/need to survive. • Some are renewable, like wood and oxygen • Some are nonrenewable, like oil

  24. Natural Selection Why do these birds have different beaks?

  25. Natural Selection • When biological traits become more or less common in a population based on the environment the organism lives in.

  26. Food Webs • In a ecosystem living things are connected by who they eat and who eats them.
