  5. Designing a Good Experiment. The most challenging part of the scientific method is usually the third step, designing and carrying out an experiment to test the hypothesis. A well-designed experiment should include all of the following characteristics: 1. An independent variable. The independent variable is the part of the experiment that the ...

  6. The basic components of a true experiment include a pretest, posttest, control group, and experimental group. Testing effects may cause researchers to use variations on the classic experimental design.

  7. A scientific investigation is a plan for asking questions and testing possible answers. A scientific investigation typically begins with observations. Observations often lead to questions. A hypothesis is a possible logical answer to a scientific question, based on scientific knowledge.
