Scientific Investigation
Steps
-
Observation
Data are gathered through the use of five senses and collecting information about the question. This will help in making a hypothesis.
-
Designing an Experiment
Designing an experiment whose results will either support or disprove the hypothesis. If the hypothesis is supported, then the results of the experiment will indicate that the hypothesis is correct. However, the results of your experiment can also prove that the hypothesis is wrong.
Collection of Data
This can be any piece of information that you collect regarding the experiment. This can be quantitative (numbers) or qualitative (descriptions). Data must be organized, which can be presented or organized into charts, tables or graph
-
Communicate the Results
Be prepared to present the project to an audience. Expect questions from the audience. There is a need to communicate the result of the scientific investigation especially in the presence of experts to verify the validity of the result.
Definition
A procedure consisting of a series of steps with the goal of problem-solving and information-gathering.
Concepts
Fair Testing
Fair testing is important in experimentation. If testing is not fair, then the results will not be accurate and this will reduce the effectiveness of the test by making the results incorrect.
