  1. Who? When? LIFE How? What? Why? Where?

  2. Develop 10 questions that include the word life in it or any derivatives of the word life. For example: What is life?

  3. What is an active class discussion?

  4. Okay let’s have an active class discussion!

  5. The Meaning of Life Active Reading Activity • Answer pre-reading def. • Read Title & Skim Article • While reading underline important information, jot down notes, ask questions and rephrase important information • Answer post-reading questions.

  6. The Meaning of Life Active Reading Activity • Definitions • Reading Comprehension questions

  7. Pouring Water Demonstration Planet 4 Planet 1 Planet 2 Planet 3 What will happen when you fill a cup with water and then turn it over?

  8. Should we be exploring other planets in search of life?

  9. In what ways have we been able to explore other planets/moons?

  10. Comparing current methods of exploration:

  11. What would be the best way to explore other planets/moon?

  12. Journal Question: What can you learn from dissecting a fetal pig? Do you think it is worth it? Explain.

  13. To truly explore other planets, we need to be able to interact without barriers.

  14. James Cameron’s Avatar

  15. Avatar • Presented by James Cameron • Skim through movie questions. • Watch movie and answer questions. • Have fun!

  16. JQ: Would you choose to be cryogenically preserved (deep freeze after death) if the technology was available? Explain.

  17. Avatar • Presented by James Cameron • Watch movie and answer questions. • Have fun!

  18. JQ: Is an Avatar living or non-living?

  19. How do you construct an Avatar?

  20. “Good science is good observation!” What does that mean?

  21. Quick Dissection Activity and Data Collection

  22. In order to understand how we will survive space exploration, we must understand how our bodies are “put together” To review organ systems thru dissection video: http://www.youtube.com/user/LakelandBiology

  23. Levels of Organization Organism Organ System Organ Tissue Cell Organelle Macromolecule Molecule Atom Subatomic Particles

  24. How can I remember all eleven organ systems? C DR SMILE RUN Cardiovascular Digestive Respiratory Skeletal Muscular Integumentary Lymphatic Endocrine Reproductive Urinary Nervous

  25. Circulatory System Function – transports substances throughout the body using heart Organs – heart, arteries/veins & blood

  26. Digestive System Function – breaks down food into usable substances & absorption through intestines Organ – esophagus, stomach, and intestines

  27. Respiratory System Function – moves air in and out of lungs Organ – trachea, pharynx, bronchi and lungs (diaphragm helps)

  28. Skeletal System Function – provides support and structure to the body, site for blood production (red and white cells), Organ – Bones

  29. Muscular System Function – allows your body to move through contraction and relaxation Organs– muscles

  30. Integumentary System Function – serves as a barrier & protects against infection (1st line of defense) Organ – skin, nails, hair follicles, sweat glands

  31. Lymphatic System Function – defend against pathogen and disease with white blood cells (2nd line of defense) Organs –lymph nodes/lymph vessels

  32. Endocrine System Function – slowly relays messages that regulate the body (growth and development) Organs – glands

  33. Reproductive System Function – production of sperm & egg cells to create offspring. Organs – testes & penis; ovaries, fallopian tubes, uterus.

  34. Urinary System Function – filters & eliminates waste from the blood Organ – kidneys, bladder

  35. Nervous System Function – quickly relays messages to and from brain through cells called neurons that regulate behavior. Organs – brain, spinal cord, sense organs

  36. Journal Question: How can you learn about yourself by dissecting the fetal pig? Explain. Link to videos

  37. What are all organ systems working toward? Homeostasis – process by which organisms keep internal conditions relatively constant despite changes in the external environment. Examples: temperature, heart rate, blood pressure, etc.

  38. Objectives: -Use technology appropriately in school -Visualize the 11 organ systems - Recognize that by studying the fetal pig you can understand how a human and is constructed. -Visualize and interconnectedness between organs and organ systems. -Develop basic dissecting skills.

  39. External Dissection • Determining the age of your pig. • Identifying the sex of the pig.

  40. External Dissection • Observing the Integumentary System. • Observing Muscular System.

  41. Male vs. Female

  42. Mouth Dissection • Identifying the tongue, soft & hard pallet. • Opening of mouth to view epiglottis. A B C D

  43. JQ: No Journal Question Today. Instead, put gloves on, your apron on, and have a seat in your desk. Your homework tonight is to complete the Dissection Lab

  44. Internal Dissection • Re-tie your pig to the dissecting tray. (tape?) • Make incisions to expose internal organs. • Identify all internal organs and show teacher. • When finished, work on Post-lab questions. Link to videos

  45. Clean-up • Put the fetal pig into the bag provided. Label bag with you & your partners names. • With soap and water clean tools and tray, return to cart. • Wipe down table and sink with wet sponge. • Return to seat.

  46. Testing your skills – Name that Organ System • Serves as a barrier & protects against infection. • Quickly relays messages from one part of the body to another. • Breaks down food into simple molecules that can be used by cells. • Brings oxygen in and carbon dioxide out. • Filters and removes waste from the blood. • Produces gametes (sperm and egg) cells. • Provides support and is a site for blood cell formation. • Allows the body to move. • Transports substances throughout your body • Slowly regulates the body’s functions. • Protects the body from disease.

  47. Testing your skills – Name that Organ System Answers • Integumentary System • Nervous System • Digestive System • Respiratory System • Excretory or Urinary System • Reproductive System • Skeletal System • Muscular System • Circulatory System • Endocrine System • Lymphatic System

  48. Testing your skills – Name as many Organs as you can for each system: • Cardiovascular System • Digestive System • Respiratory System • Skeletal System • Muscular System • Integumentary System • Lymphatic System • Endocrine System • Reproductive System • Urinary System • Nervous System
