Title: Scientific Process Skills


1
Scientific Process Skills
  • Ms. Tipple 7th 8th grade Science

2
Observing
  • Refers to use of 5 senses to gather data about
    objects events

3
Classifying
  • Involves grouping objects or events according to
    similar characteristics (e.g., shape, color, size)

4
Communicating
  • Involves use of spoken written words, graphs,
    drawings diagrams to share information ideas

5
Using Space/Time Relationships
  • Involves developing an awareness of phenomena
    events outside of ones immediate environment
    (e.g., which soap has longest lasting bubble,
    which molecules are farther apart)

6
Measuring
  • Scientists gather share data about the world by
    using common standards of measurement (e.g.,
    length, mass, volume, time).

7
Using Numbers
  • Quantification is the essence of science, the
    ability to describe the world numerically is
    basic to all scientific endeavors

8
Formulating Hypotheses
  • Scientific explanation that can be tested is a
    key skill in the scientific method

9
Inferring
  • Logical thought process to show a relationship
    between two or more observations

10
Predicting
  • Forecasting future events based on observations
    inferences

11
Defining Operationally
  • An operational definition is a definition framed
    in terms of experiences. For example, defining
    an acid as any substance that turns blue litmus
    red is an operational definition.

12
Experimenting
  • Combines all of the process skills used in
    conducting a scientific investigation

13
Forming Models
  • A model is a verbal structure of graphic
    representation of the physical world. Scientists
    develop models as a way of describing the world,
    then test refine those models as more
    information becomes available

14
Controlling Variables
  • In a science experiment, two conditions, alike in
    every way but one, are compared to determine the
    influence of the one missing element

15
Interpreting Data
  • Involves the analysis synthesis of data to
    support or refute a hypothesis

16
Independent variable
  • Something that the scientist changes
  • Ask yourself What is changing?

17
Dependent Variable
  • What is being measured?

18
control
  • What is staying the same?
