1. Biology Grade 9 Mrs. Webb

2. The Science of Biology Chapter 1

3. Section 1-1 What is Science? The Goals of Science are to: investigate and understand nature –in a careful & organized way –looking for patterns and connections

4. explain events in nature & make useful predictions – deals only with the natural world –explanations can be tested by examining evidence

5. understand the wisdom & glory of the Creator, God –Genesis 1:1 –Hebrews 11:3 –Psalm 19: 1-3

6. Biology Through the Eyes of Faith “If we follow our observations of beauty, order, and purpose in the natural world to a realization that all of this speaks of a Creator,

7. God invites us to take the next step and find that the Creator has also come to redeem His creation.” Richard T. Wright

8. Science is an organized way of using evidence to learn about the natural world and the Creator of the natural world

9. In Small Groups Use your Bible to find at least three scriptures that speak about creation or science Write them out on the paper provided

10. Science is –an on going process –not the discovery of unchanging, absolute truth –always subject to revision as new evidence is developed

11. Problem Solving Attitude assume basic rules & use scientific inquiry to discover those rules collect data to better understand nature

12. Desirable Qualities Curiosity Honesty Open-mindedness Skepticism Recognition that science has limits

13. Limitations of Science Presuppositions (assumptions) Proof Domain limitations Human involvement

14. Science begins with Observation using one or more of the senses to gather information information gathered is called Data

15. Data can be –Quantitative - involves #’s –Qualitative - involves characteristics not easily measured

16. “Look at the fish”

17. Look at the Candle

18. “There are two yous: the visible you that is known by others and the real you that is known only by God.”

19. Observation is followed by inference A logical interpretation based on prior knowledge and experience –must be logical, not merely a feeling about the evidence

20. Look at the Candle

21. Worldviews function as a guide to life determine values help us to interpret what we see and evaluate the events that cross our pathway each day cultural

22. Worldviews in Conflict Native American population and European settlers of New England

23. Group Discussion How might the different worldviews in this classroom affect our ability to do group work? (Be sure to consider positives as well as negatives!)

24. Flip It

25. The Scientific Method a systematic approach to problem solving a way of thinking using logic and reason NOT a rigid set of steps

26. Explanation of the Evidence Hypothesis –a possible explanation for a set of observations –an educated guess based on current knowledge

27. –is useful only if it can be tested testing can be done by further observation or careful questioning

28. Scientific Method Controlled Experiment - one variable changes at a time Variables - factors that can change, like equipment used, type or amount of materials, temperature, light, time, etc.

29. Manipulated Variable - factor that is deliberately changed Responding Variable - factor that changes in response to the manipulated variable

30. Scientific Method Three interacting parts shaping principles (values and assumptions) data (quantitative/qualitative) theories (explanation that has been tested by repeated observations)

31. Theories must be... Objective (consider all data) Rational (use logical thinking when making connections) Generalized (extended in their application)

32. Hip-Hop Scientific Method Scientific

33. Biology The study of living things or organisms ( any living thing) Many different levels (page 21) Many different branches

34. Branches of Biology Zoology - animals Botany - plants Ethology - behavior Paleontology - past

35. Cytology - cells Genetics - heredity Histology - tissues Epidemiology - epidemics

36. 8 Characteristics of Living things Go outside and observe different living things Make a list of the common characteristics that you see

37. Characteristics of Living Things Made of cells –highly organized, tiny structures with thin membrane coverings, the building blocks of all organisms –Unicellular/Multicellular

38. Reproduce –make more organisms of their own kind Sexual - 2 cells, 2 parents Asexual - 1 parent (budding, cell division)

39. Based on a Genetic Code –DNA, Genes ( inherited instructions) –heredity - passing of traits from parent to offspring

40. Grow and Develop –have a distinctive life cycle or particular pattern of growth & change that occurs over it’s lifetime

41. –increase in size (growth) –increase in complexity (development) –have a lifespan - all eventually die

42. Use Energy –Metabolism: sum of all chemical reactions carried out by an organism

43. –Obtain energy in a variety of ways (photosynthesis, herbivorees, carnivores, omnivores, decomposers)

44. Respond to their Environment –Stimulus =Response –Nervous system, sensory organs, Immune system, Regulatory system

45. Maintain an Internal Balance –Homeostasis - maintaining balance internally in spite of external changes –example: amount of water in cells

46. Taken as a group, Living things Change over time (evolve) Adaptation: improves survival Variation: range of expression Mutation: change in DNA

47. Everyday Life Read page 22 Write a paragraph explaining how Biology touches your life every day.

48. Exploration Using a Compound Microscope Page 29

49. Biology Current Events Purpose: To become aware of and develop an appreciation for science that is happening right now in the world around us.

50. Find an article about a scientific topic in a newspaper or magazine The article must be 1 page or longer Copy the article

51. Type a summary of the article Include names of key people, the hypothesis or focus of research,findings/conclusions, your thoughts on the article (agree, disagree, benefits, etc)

52. PRESENT findings to the class (3 minute report) TURN IN a copy of your article and your written summary (Summary should be 2-5 paragraphs - 1 page long)

53. 1 current event per quarter worth 50 points Your first one is due on September 10th
