About This Quiz & Worksheet

In this quiz/worksheet combo students will be tested on ways to design scientific experiments that produce consistent results each time they are performed. Potential solutions to problems like random error and insufficient data collection will be presented in an easily accessible and interactive format.

Quiz & Worksheet Goals

In this assessment you'll be tested on:

  • The definition of a variable
  • Why it is important to control variables in an experiment
  • Why it is good practice to run an experiment multiple times

Skills Practiced

  • Interpreting information - verify that you can read and correctly interpret information regarding how to ensure consistent results in scientific experimentation.
  • Defining key concepts - ensure that you can accurately define main phrases, such as random error, experimental error, variable and control variable.
  • Distinguishing differences - compare and contrast topics from the lesson, such as variables and control variables, random error and experimental error.
  • Knowledge application - use your knowledge to answer questions about the best practices to use in designing experiments that will consistently produce the same result.

Additional Learning
