  1. Chapter 2 Science Test Notes: 8th Grade

  2. Mathematics is not used to learn a foreign language. • A column is not a feature of a graph. • An independent variable can be found in a data table.

  3. If a graph shows the relationship between the independent variable and the dependent variable as a curved line, the graph is nonlinear.

  4. If a graph shows the relationship between the dependent variable and independent variable with a straight line, the graph is linear.

  5. A system of ideas that explains observations and is supported by a large amount of scientific evidence is called a theory. • Economic is not a type of model that is commonly used in science that uses familiar things to describe unfamiliar things.

  6. A calculator is not used to take accurate measurements while collecting data. • The International System of Units is based on the number 10. • A summary of many experimental results and observations is called law.

  7. Data tables and graphs are useful for organizing data. • A constant is the value of the slope between any two points on a straight line. • A data table is not used to get accurate measurements.

  8. A graduated cylinder does not use familiar things to describe unfamiliar things. • Scientific data should be rejected by scientists if the data is not reproducible. • In the equation y=kx, the slope of the line is represented by the constant k. • To get an accurate data reading, scientists must be sure to use the right tool.

  9. Scientific models have limitations because they do not act exactly like the real thing. • Graphs and data tables are used to organize data.

  10. A law that describes what happens can • be constructed after a model verifies the • results of multiple experiments. • A system of ideas that explains related • observations and is supported by a large • body of scientific evidence is called a • theory.

  11. A model represents a system or an object and uses familiar things to describe unfamiliar things. • The International System of Units is used by many scientists, and changing from one unit to another is easy. • Using tools to take accurate measurements is a way to collect data.

  12. In order for scientific data to be accepted, they must be reproducible. • A computer is a tool that can be used to make a mathematical model. • A model of a galaxy forming is an example of a conceptual model.

  13. A meterstick, stopwatch, balance, and a computer are tools that can be used for collecting and analyzing data in science. • If a line of data is sloping upward, the numbers reflecting the information being gathered is increasing. • Measurement tools are used to collect data during an experiment.

  14. Slope is Not calculated by dividing the run by the rise.
