  1. Chapter 1Biology: The Study of LifePages 1 to 33 Section 1.1: What is Biology? Section 1.2: The Methods of Biology Section 1.3: The Nature of Biology

  2. Priority academic student skills: P.A.s.s. • This chapter is an introduction into the SCIENCE PROCESSES & INQUIRY: • Process Standard 1: Observe and Measure – all parts • Process Standard 2: Classify – all parts • Process Standard 3: Experiment – all parts • Process Standard 4: Interpret and Communicate – all parts • Process Standard 5: Model • Process Standard 6: Inquiry

  3. Section 1.1what is biology? • Objectives: • RECOGNIZE some possible benefits from studying biology • SUMMARIZE the characteristics of living things. • New vocabulary : page 3 (14) • Student is responsible for defining the new vocabulary to properly prepare for the exam.

  4. Section 1.1:the science of biology • The Science of Biology • Biology means the study of life because bios means “life” while logos means “study”. • Biologists study the interactions of life • Refer to Figure 1.1 on page 4

  5. Section 1.1:biologists study the diversity of life • Biologists Study the Diversity of Life • Biologists study the interactions of the environment. • Living “things” cannot live in isolation. Interaction of living “things” to the environment must be investigated. • Refer to Figure 1.2 page 5 • Answer the Reading Check at the bottom of page 5: EXPLAIN why scientists study an organism’s environment.

  6. Section 1.1:biologists study the diversity of life • Biologists Study the Diversity of Life • Biologists study problems and propose solutions • Refer to Figure 1.3 page 5 • The study of biology will teach you how humans function and how we fit in with the rest of the natural world.

  7. Section 1.1:characteristics of living things • Characteristics of Living Things • Anything that possesses all the characteristics of life is known as an ORGANISM. • All living things: Must know • Have an orderly structure. • Produce offspring. • Grow and develop • Adjust to changes in the environment.

  8. Section 1.1:characteristics of living things • Characteristics of Living Things • Living things are organized. • All living things show an orderly structure, or ORGANIZATION • Refer to Figure 1.5 page 7 • Living things make more living things • REPRODUCTION is the production of offspring. • SPECIES is a group of organisms that can interbreed and produce fertile offspring in nature.

  9. Section 1.1:characteristics of living things • Characteristics of Living Things • Living things change during their lives • GROWTH results in an increase in the amount of living material and formation of new structures. • DEVELOPMENT is all of the changes that takes place during the life of an organism.

  10. Section 1.1:characteristics of living things • Characteristics of Living Things • Living things adjust to their surroundings • Another name for surroundings is the ENVIRONMENT. • Environment includes the air, water, weather, temperature, any other organisms in the area, and other factors.

  11. Section 1.1:characteristics of living things • Characteristics of Living Things • Living things adjust to their surroundings – continued • STIMULUS is anything in an organism’s external or internal environment that causes the organism to react. • A reaction to a stimulus is a RESPONSE.

  12. Section 1.1:characteristics of living things • Characteristics of Living Things • Living things adjust to their surroundings – continued • HOMEOSTASIS is the regulation of an organism’s internal environment to maintain conditions suitable for its survival. • Examples of homeostatis are maintaining temperature, water amount, mineral content, filtration of fluids, etc.

  13. Section 1.1:characteristics of living things • Characteristics of Living Things • Living things adjust to their surroundings – continued • ENERGY is the ability to cause change. • Energy is obtained by the foods that are consumed by the organism.

  14. Section 1.1:characteristics of living things • Characteristics of Living Things • Living things adapt and evolve • ADAPTATION is any inherited structure, behavior, or internal process that enables an organism to respond to environmental factors and live to produce offspring. • EVOLUTION is the gradual change in a species through adaptations over time

  15. Section 1.1:Section ASSEssment • Understanding Main Ideas • Answer #2 to #4 • Thinking Critically • Answer #5 • SELF CHECK QUIZ • http://www.bdol.glencoe.com\self_check_quiz

  16. Section 1.2The methods of biology • Objectives: • COMPARE different scientific methods • DIFFERENTIATE among hypothesis, theory, and principle. • New vocabulary : page 11 (9) • Student is responsible for defining the new vocabulary to properly prepare for the exam. • Also include any Review Vocabulary.

  17. Section 1.2:the methods of biology • Why does rain bring out the worms? • Read this short paragraph for clarification of what section shall present. • Refer Skill Handbook – pg. 1104 to 1109 • Observing and Hypothesizing • The methods biologists use • SCIENTIFIC METHODSare the common steps that biologists and other scientists use to gather information and answer questions

  18. Section 1.2:the methods of biology • Observing and Hypothesizing • The question of brown tree snakes • Read and refer to Figure 1.10 page 12 • HYPOTHESIS is an explanation for a question or problem that can be formally tested. • Not a random guess. • The explanation is based on observation and researching the event or situation.

  19. Section 1.2:the methods of biology • Experimenting • EXPERIMENT is an investigation that tests a hypothesisby the process of collecting information under controlled conditions. • What is a controlled experiment? • CONTROL is the part of an experiment that is the standard against which results are compared. • Control receives no experimental treatment. • Read Figure 1.11 for further understanding.

  20. Section 1.2:the methods of biology • Experimenting - continued • Designing an experiment • Independent variable • The only factor that affects the outcome of the experiment. • On a line or bar graph, the x-axis title. • Note: Independent starts with an “I”. I change the factor of the experiment.

  21. Section 1.2:the methods of biology • Experimenting - continued • Designing an experiment • Dependent variable • The result of independent variable usually in a quantitative value. • On a line or bar graph, located on the y-axis. • The dependent variable “depends” on the independent variable. • READING CHECK on top of page 14.

  22. Section 1.2:the methods of biology • Experimenting – continued • Using tools • Know the following measurements including the tools and the units used to describe each. • Measurements include: length, volume, and mass.

  23. Section 1.2:the methods of biology • Experimenting - continued • Maintaining safety – Use pg. 1107 to 1109 • Safety symbol is a symbol that warns you about a danger that may exist if chemicals, electricity, heat, or procedures you will use. • Refer to pages 1107 to 1109 and Table 1.1 on page 15. Information must be looked at because they shall be on EOI, chapter exam, benchmark exam & semester exam.

  24. Section 1.2:the methods of biology • Experimenting – continued • Data gathering • Data is the information obtained from investigations. Also referred to as experimental results. • Two types of data: numerical and descriptive. • Refer to pages 1060 & 1061.

  25. Section 1.2:the methods of biology • Experimenting – continued • Reporting results • Results and conclusions of investigations are reported in scientific journals, where they are available for examination by other scientists. • Verifying results • Data and conclusions are shared with other scientists for an important reason. • Thinking about what happened • Often, the thinking that goes into analyzing data takes the greatest amount of scientist’s time.

  26. Section 1.2:the methods of biology • Experimenting - continued • Scientific Methods – Figure 1.14 on page 17 • Students are responsible for being able to list and describe each of the steps for the scientific method. • Theories and laws • Theory is an explanation of a natural phenomenon that is supported by a large body of scientific evidence obtained from many investigations and observations.

  29. Section 1.3:the nature of biology • Two Ways to Describe Things • Read this short paragraph • Kinds of Information • Quantitative Information • Usually consist of a number and an unit such as 50 meters. • Also known as numerical data • Measuring in the International System • Student is responsible for this information. • Must know the types of measurements, tools and the units. • Refer to Skill Handbook in back of textbook.

  30. Section 1.3:the nature of biology • Kinds of Information - continued • Qualitative information • Observational data --- that is, written descriptions of what scientists observe --- are often just as important in the solution of a scientific problem as numerical data or quantitative information.

  31. Section 1.3:the nature of biology • Science and Society • ETHICS refers to the moral principles and values held by humans. • Can science answer all questions? • Some questions are simply not in the realm of science such as good v. evil. • Can technology solve all problems? • TECHNOLOGY is the application of scientific research to society’s needs and problems.
