  1. Bell Ringer • You are a scientist working for NASA. You’ve just taken some pictures of a possible new life form. Explain how you would know whether or not this recently discovered “creature” is living.

  2. AGENDA • Bell Ringer • Today’s objective • Unit 2 Performance Task • Lion King Video clip • Abiotic vs Biotic Factors • Class Practice • Homework assignment

  3. Today’s objective • SWBATdefine the 6 characteristics of life in order to later categorize factors asbiotic or abiotic.

  4. UNIT 2 PERFORMANCE TASK • Students will be provided with an animal and in pairs decide the following: the animals living condition, a name, physical characterisitics (height, length, weight, etc.), a behavioral adaptation, a physical adaptation, what the animal eats, what if any endangers the animal may face, where can the animal be found. environment? • The audience will be a panel from WWF and it’s community members who want to learn about the living organism and its specific requirements to survive in its envirionment

  5. So…what makes something living? • How do you know if something is living or not? • Can non-living things share characteristics of living things? • http://www.youtube.com/watch?v=gvQNp1NMg5Q • As you are watching the video make a list of living and non-living things you see

  6. Which of these things are alive? Plants air wind animals bacteria viruses rocks fungi soil water

  7. Characteristics of Life All living things share 6 characteristics, called the characteristics of life. Something must have ALL SIX of these characteristics in order to be considered “living.”

  8. 1. Living things are made of CELLS! • All organisms have 1 or more cells • Cells are the basic units of living things. • A living thing can be 1 cell (UNICELLULAR) or MANY cells (MULTICELLULAR)!

  9. 2. Living things reproduce.

  10. Living things reproduce • Living things pass hereditary information to new organisms through reproduction • It’s not just people, animals, or insects that do this but moss, mold, and bacteria do it too Think about it— Can an organism reproduce with just one parent? How do we pass on our traits?

  11. 3. Living things have a genetic code. • DNA, or deoxyribonucleic acid, determines inherited traits

  12. 4. Living things GROW and DEVELOP • Every living thing grows and develops • During development cells divide over and over • When cells divide they begin to look different and serve • different functions

  13. 4. Grow and Differentiate • Differentiation = organisms develop to become more complex over their life span

  14. 5. Use Energy • Every movement and action requires energy! • For example, as you are listening to me, your eye and brain cells are hard at work, using a lot of energy to focus • Every organism must: • make or obtain food • And convert it to energy

  15. 6. Living things respond to their environment AND maintain homeostasis • EXAMPLES: Plants respond to the direction of light • Ants move toward crumbs • Bacteria respond to antibiotics • Human react (quickly and automatically) to pain • Homeostasis—process by which organisms maintain a relatively stable internal environment even when environment around them changes

  16. Homeostasis example:your body temperature does not change

  17. Living things*… • are made of cells. • reproduce. • have a genetic code (DNA). • grow and develop. • obtain and use nutrients for energy. • respond to their environment and maintain homeostasis Living things AKA *ORGANISMS*

  18. BUT in order to be considered alive an organism must do ALL NOT just some of the above characteristics!!

  20. Ecology Unit 2

  21. Bell Ringer 1. Birds, mammals and theropod dinosaurs can maintain a constant body temperature. The ability to maintain a constant body temperature is an example of: a. Respiration c. Homeostasis b. An acquired trait d. Evolution • Name 3 characteristics that living things share. • Can something be considered living if it only has 4 of the 6 characteristics of life?

  22. KEY TERM #1 : Ecology is the scientific study of two things: 1. interactions among organisms 2. the interactions between organisms and their environment.

  23. KEY TERM#2: An ecosystem is all the living and non-living things in an area and their interaction with each other.

  24. Abiotic (physical) factors – something that is not alive and never was.EXAMPLES:SoilRocksTemperatureWaterSunlightPollutants

  25. Biotic Factors- something that is living or was once living.examples: plants, animals, bacteria, fungus, etc.) BIO= Life -> Biotic = living

  26. Biotic or Abiotic? A

  27. Biotic or Abiotic?

  28. Biotic or Abiotic?

  29. Biotic or Abiotic?

  30. Biotic or Abiotic?

  31. Biotic or Abiotic?

  32. Biotic or Abiotic?

  33. Biotic or Abiotic?

  34. Biotic or Abiotic? • Biotic or Abiotic?

  35. Biotic or Abiotic? **REMEMBER** BIOTIC FACTORS include things that are dead but were once alive AND anything that CAME FROM A LIVING THING
