1. Board Work What are some characteristics of living things? Which of these characteristics does each object have

2. Chapter 1: What is Biology? Collecting Biological Data

3. Biology - The Study of Life “Bios” = Life “logos” = Study Biology = The study of life

4. Biologists Study the Diversity of Life Biologists study the interactions of life Biologists study the interactions of the environment Biologists study problems and propose solutions - i.e. medical treatment, disease prevention etc.

5. What is an Organism? All living things are organisms

6. Characteristics of Living Things Organization Reproduction Growth and Development Ability to adjust to Environment Living things adapt and evolve Video

7. Organization All living things are composed of one or more cells Each cell contains DNA All parts function together in an orderly living system

8. Reproduction Species They can interbreed The offspring that they produce are fertile

9. Growth and Development Growth - Results in more living material and forms new structures Development - All changes that take place during the life of an organism

10. Ability to adjust to Environment Environment - air, weather, temperature, other organisms, and many other factors Stimulus: Any condition that requires a response Response: Reaction to a stimulus Homeostasis: maintaining conditions suitable for survival - takes energy

11. Living Things Adapt and Evolve Adaptation: Any structure, behavior, or internal process that enables an organism to respond to stimuli and better survive in an environment Evolution: gradual accumulation of adaptations over time

12. Chapter 1 1.2 - The Methods of Biology

13. The Scientific Method Make observations And collect data that Lead to a question Formulate Hypothesis Test Hypothesis: Experiments - collect data Interpret Results, and revise the hypothesis if necessary State Conclusions in a form that can be evaluated by others SCIENTIFICALLY PROVEN X

14. The Scientific Method Examples of the scientific method

15. Controlled Experiments Control Group All conditions kept the same Experimental Group All conditions kept the same EXCEPT ONE

16. Controlled Experiments Frog Egg Experiment

17. The Variables in an Experiment Independent Variable The condition in an experiment that is changed There should only be one independent variable Dependent Variable A condition in an experiment that changes because the independent variable changed

18. Controlled Experiments Frog Egg Experiment Independent Variable =UV light

19. Controlled Experiments Frog Egg Experiment Dependent Variable =Size of Eggs

20. Scientific Tools Beakers Test tubes Hot plates Petri dishes Graduated cylinders Dissecting instruments Microscopes

21. Theories and laws Theory: A hypothesis that is supported over a long period of time. Law: Fact of nature that is generally known to be true. E.g. the law of gravity (what goes up must come down).

22. Chapter 1 1.3 - The Nature of Biology

23. 2 Kinds of Research Quantitative: dealing with numerical data (counts/measurements) Uses the International system of measurement (SI) meter gram liter second Celsius

24. 2 Kinds of Research Quantitative: dealing with numerical data (counts/measurements) Uses the International system of measurement (SI) meter (length) gram (weight) liter (volume) second (time) Celsius (temperature)

25. 2 Kinds of Research Descriptive: Uses written descriptions of what a scientist observes. E.g. Animal behavior

26. Science and Society Ethics: moral principles and values held by humans Society plays a vital role in determining what is ethical or not ethical when it comes to science Why should I care about science? Does God care about science?

27. Misconceptions about the relationship between Science and Religion Science has all the facts Science and religion should be separate and independent from each other If science does not agree with the Bible, then bend the bible a little

28. True Science “God is the foundation of everything. All true science is in harmony with His works; all true education leads to obedience to His government.”
