  1. Vocabulary Review Chapter 1 Tools, Scientific method, graph (student notes)

  2. Uses one of the five senses to gather information about an object or event; process of noticing and describing events in a careful, orderly way observation

  3. A collection of evidence, information gathered thru observations or experimentation data

  4. A well tested explanation that unifies a broad range of observations & allows scientists to make accurate predictions theory

  5. Possible explanation for a set of observations or possible answer to a scientific question hypothesis

  6. Factors that can change in an experiment variable

  7. Variable being observed or measured in an experiment Dependent variable

  8. Variable or factor in an experiment that is changed purposely by the experimenter Independent variable

  9. 5 major parts: title, independent variable, dependent variable, scale, legend graph

  10. Includes independent and dependent variables in a graph title

  11. Graph the independent variable on the __axis X-axis

  12. Graph the dependent variable on the __axis Y-axis

  13. Short descriptive narrative concerning the graph’s data The Legend

  14. A test that changes only one variable and keeps all other variables the same experiment

  15. A procedure that tests a hypothesis by collecting information under controlled conditions Scientific method

  16. Observations with numerical values; units, graphs and charts quantative

  17. Observations reported using words and descriptions; no numbers qualitative

  18. The group in which all conditions are kept the same in an experiment Control group

  20. Scientist that studied maggots using gauze and jars (1st controlled experiment) Redi

  21. Scientist that studied bacteria using a “swan neck or S-shaped flask Pasteur

  22. basic unit of all forms of life (living organisms) cell

  23. 8 characteristics of Life • Reproduction • Universal Genetic Code • Growth & development • Energy use and metabolism • Response to to their environment (homeostasis) • Maintain a stable internal environment • Living things evolve

  24. An organism made of only ONE cell unicellular

  25. Molecule that contains genetic code of living organisms DNA

  26. An organism made of many cells multicellular

  27. The combination of genetic material from two parents to create first cell of new organism (zygote)..offspring different from parents Sexual reproduction

  28. Reproduction involving 1 parent that results in offspring that are genetically identical to the parent Asexual reproduction

  29. The process by which an organism grows and changes over time(from egg to adult) development

  30. Increase in size; number of cells Growth

  31. Signal to which an organism responds stimulus

  32. A reaction to an environmental condition response

  33. A change over time among a group of organisms evolution

  34. chemical reactions that take place within an organism ( or cell) to build up and break down needed materials metabolism

  35. The process by which an organism maintains relatively stable internal conditions homeostasis

  36. Organisms that can capture energy from sunlight or chemicals and use it to produce its own food autotroph

  37. Organism that obtains energy from the food it consumes; can’t make its own food heterotroph

  38. Another name for a living thing organism

  39. The “Science of Life” that studies all livings things biology

  40. An organism that uses chemicals such as iron and sulfur to get energy chemoautotroph
