1.1. The Methods of Science

Expectation: Recognize that ______is a progressive endeavor that re-evaluates and extends what is already accepted.

  1. ______is a method of studying the natural world. It is a process that uses ______to gain knowledge about events in nature. Science can be classified into 3 main catagories:
  2. ______-studies living things
  3. ______-investigates earth and space
  4. ______-studies matter and energy.
  5. Investigations: Investigations can be done in many ways. Sometimes scientists perform ______; Other times they simply ______something that occurs and record their observations. And sometimes, they will build ______to resemble something in nature and then tests this to see how it acts.
  6. Scientific Method: an organized set of ______. There are 6 common steps in the scientific method:
  7. ______
  8. ______
  9. ______
  10. ______
  11. ______
  12. ______
  13. An ______is a possible answer for a problem. It is your best guess. A common way to test this is to perform an ______. An ______tests the effect of one thing on another using ______. A ______is a quantity that can have more than a single value. A ______variable changes according to the changes in other variables. The variable you change to see how it will affect the dependent variable is called the______variable. A factor that does not change when other variables change is called a ______. A ______is the standard by which the test results can be compared. Valid experiments must have data that is ______and it must be ______.

V. Models: A ______represents an idea, event or object to help people better understand it. Today scientists use ______to build models.

VI. Theories and Laws:

a. A scientific ______is an explanation of things or events based on knowledge gained from many observations and investigations.

b. A scientific ______is a statement about what happens in nature that seems to be true all the time. ______is an example of a scientific law.

C. ______is the application of science to help people.

1.2. Standards of Measurement

  1. A ______is an exact quantity people agree to use for comparisons of measurements. For a measurement to make sense, it must include a ______and a ______. In the United States we commonly use the ______system of measurement.
  2. Most other nations use the ______system. It is based on multiples of ______. All ______standards are universally accepted and understood by scientists throughout the world. The standards are kept in ______. (Under this paper, copy the SI Base Units chart to study.)
  3. Volume- ______. The formula for volume is V = ______Volume is expressed in ______.
  4. ______is measurement of matter in an object. ______is the mass per unit volume of material. The formula for density is ______. The measurement unit for density is g/cmA. This is a combination of SI units. A unit obtained by combining different SI units is called a ______. An SI unit multiplied by itself is also a derived unit such as cm2.
  5. ______is the interval between two events. The SI unit for time is the ______.
  6. For most scientific work temperature is measured in _____. On this scale the freezing point of water is ______and the boiling point of water is ______. The SI unit of temperature is the ______. Zero on the Kelvin scale is the ______possible temperature. This is also known as ______. Absolute zero is equal to ______below the freezing point of water. Kelvin temperature can be found by adding _____ to the Celsius reading.

1.3. Communicating with Graphs.

  1. A ______is a visual display of information or data. The horizontal axis, or the ______axis, measures ______on a distance-time graph. Time is the ______variable because as it changes, it affects the measure of another variable.
  2. Different kinds of graphs
  3. ______: used to ______
  4. ______: used to ______
  5. ______: used to ______
  6. Constructing Graphs: Use the ___-axis for the independent variable and the ____ -axis for the dependent variable.

VI. For most scientific work temperature is measured in _____.
