1. Q.O.D. What features identify an organism as a living thing? How would you identify an unknown object as an organism?

2. Chapter 1 The Study of Life

3. Section 1 Introduction to Biology

4. What do Biologists do/study? Study the diversity of life – Jane Goodall Field Study- Chimpanzees – Charles Darwin Field Study- Finches Research diseases – Genetics Humans vs. Chimpanzees- 99% identical Develop technologies – “Bionic Hand” – Medical/medicine Improve agriculture – Genetically engineered crops- Why? Preserve the environment – Endangered Species

5. Q.O.D. If you could be any living organism, what kind would you be? List the characteristics that it has that makes it a living organism using specific examples for each.

6. Do Now: In groups, you will be given one of the characteristics of life. Your job is to find a way to illustrate that characteristic either in a picture, a poem, a story or a song.

7. Characteristics of Life Made of cells – Prokaryotic vs. Eukaryotic – Unicellular vs. multicellular Displays organization – Cells, tissues, organs, organ systems Grows and Develops – Growth – Development

8. Characteristics of Life Reproduces – Asexual reproduction – Sexual reproduction Responds to stimuli – Stimulus – Response Requires energy

9. Characteristics of Life Maintains homeostasis – Examples – Feedback mechanisms – Importance Adaptations evolve over time – Adaptations – Natural selection

12. Q.O.D. What is science? What is pseudoscience? How can you tell the difference?

16. Section 2 The Nature of Science

17. What is Science Relies on evidence Expands scientific knowledge Challenges accepted theories Question results Tests claims Uses the metric system

18. Q.O.D. What does it mean that questions posed by science are “testable?” Provide examples of questions that are testable and examples of questions that are not testable.

19. Q.O.D. How many milligrams are in 2 kilograms?

20. Section 1.3 Summary – pages 19-23 Scientists always report measurements in a form of the metric system called the International System of Units, commonly known as SI.

21. Section 1.3 Summary – pages 19-23 Measuring in the International System In biology, the metric units you will encounter most often are: meter (length), meter (length), gram (mass), gram (mass), liter (volume), liter (volume), second (time), and second (time), and Celsius degree (temperature). Celsius degree (temperature).

22. Metric conversions Metric units are based in multiples of 10 Kilo___ = x 1,000 Deka___ = x 10 Deci___ = x 1/10 Centi___ = x 1/100 Milli___ = x 1/1,000

24. Section 3 Methods of Science

25. Q.O.D. What is a controlled experiment? Describe the parts.

26. Scientific Method

27. Observing and inferring Asking a question Hypothesizing – Predictions – Validity Collecting data – Observations – Measurements – Sampling

29. Redi’s Experiment

30. Experimenting – Controlled experiment Control group vs. experimental group Independent variable and dependent variable Analyze data Drawing Conclusions – Modeling – Inferring – Forming a theory

31. Microscopy and Measurement Light microscopes Electron microscopes Measurement: – Metric system

32. Section 4 Tools and Techniques Chapter 1 Object Size and Magnifying Power of Microscopes

33. The Microscope

34. Transmission Electron Microscope

35. Scanning Electron Microscope

36. Avian Flu Virus Image

37. Tips on Use Start on low power objective lens Locate image, then center image Revolve nosepiece to high power objective Do NOT use coarse adjustment now Use fine adjustment to clarify image If image is lost, return to low power objective lens and start again

38. Returning Microscope Remove slide from stage Revolve nosepiece so that lowest power objective lens is facing down Use coarse adjustment to lower body tube as low as it will go Wrap up wire and cover it and then return it to cabinet
