  1. Chapter 1What is Science Grade 8

  2. When scientists create a representation of a complex process, they are • making models. • inferring. • predicting • classifying.

  3. Explaining or interpreting the things you observe based on reasoning from what you already know is called • observing. • inferring. • predicting. • classifying.

  4. Using one or more of your senses to gather information is called • observing. • inferring. • predicting. • classifying.

  5. Observations that deal with descriptions that cannot be expressed in numbers are called • manipulated observations. • quantitative observations. • qualitative observations. • operational observations.

  6. One useful tool that may help a scientist interpret data by revealing unexpected patterns is a • variable. • graph. • theory. • law.

  7. Making a statement or claim about what will happen in the future based on past experiences or evidence is called • observing. • inferring. • predicting. • classifying.

  8. In science, a hypothesis must be • correct. • manipulated. • controlled. • testable.

  9. In a scientific experiment, facts, figures and other evidence gathered through observations are called • data. • laws. • dependent variables. • independent variables.

  10. When scientists put things into categories or group together items that are alike in some way, they are • making models. • inferring. • predicting. • classifying.

  11. Palm reading and astrology are examples of . . . • empirical evidence. • qualitative observations. • pseudoscience. • objective reasoning.

  12. During an experiment, if you purposely change the temperature to test a hypothesis, the temperature is called the • independent variable. • experimental variable. • hypothetical variable. • dependent variable.

  13. A summary of what you learned from a scientific experiment is called a(n) • hypothesis. • inquiry. • conclusion. • law.

  14. A scientist’s open-mindedness should always be balanced by ____, which is having an attitude of doubt. • skepticism • curiosity • creativity • bias

  15. During an experiment, which factors must be controlled so that researchers can draw logical conclusions from the experiment? • variable • hypotheses • inquiries • theories

  16. To find out why food left on the kitchen counter eventually molds is an example of • using scientific inquiry • developing a theory • making a prediction • collecting data

  17. If you conduct an experiment and draw conclusions that are based on your beliefs rather than the facts, you are using • subjective reasoning. • objective reasoning. • faulty reasoning. • experimental reasoning.

  18. Be able to read a data chart and identify: • The independent variable • The dependent variable • Be able to make a prediction about future data • Be able to draw a conclusion based on given data

  19. Similar to the Variables worksheet… Be able to read a scenario and identify • The manipulated/independent variable • The responding/dependent variable • The controlled variables

  20. Be able to read a data chart and • Create a line graph with titles and a key • Explain the dependent and independent variable. • Explain variables that need to be controlled in the experiment. • Make conclusions from the graph/table.
