1. Biology I UNIT 1 NATURE OF SCIENCE

2. Science An organized way of using evidence to learn about the natural world. It is both a body of knowledge and a process.

3. Biology Biology is the study of life (organisms)

4. Characteristics of life Orderly structure or organization cells→tissues→organs→organ systems→organism 2. Reproduction species 3. Growth and Development 4. Respond to stimuli

5. Stimulus Response Adaptation Internal environment

6. Nature of Science Equipment, Procedures, and Safety

7. 1.1 Handling, Measuring, and Storing Liquids Accuracy-a correct measurement; how close you are to the target.

8. Precision- reproducibility of the measurement. It also be thought of as how many decimal places are in a measurement.

9. Do accuracy and precision go hand in hand?

11. Measuring and Dispensing Liquids Graduated cylinder - accurately measures volumes of liquids, usually in mL. Read the bottom of the meniscus.

12. Pipettes, Syringes, Burettes Syringe

13. Handling and Storing Liquids Test tubes-used for mixing and handling.

14. Beakers and Erlenmeyer Flasks

15. 1.2 Scientific Measurements Measuring Mass and Weight

16. Mass A measurement of how much matter is in an object. Is constant Unit of measure-gram Instrument of measure-balance

17. Triple Beam Balance

18. Reading a triple beam balance

19. Weight A measurement of the force of gravity on an object. Changes in relationship to force of gravity. Unit of measure - Newtons (N) Instrument of measure - spring scale

20. Measuring Length Metric rulers or meter sticks are used to determine length in meters, centimeters, or millimeters.

21. Determining Temperature Temperature is a measure of the average kinetic energy of particles in an object. Thermometers measure temperature in degrees Celsius ( o C)
