Which of the following is an observation and not an inference?
Which of the following is the correct order for the steps of scientific inquiry?
A dependent variable is
A scientific theory _______.
Which type of graph is best for analyzing quantitative dependent and independent variables?
Which of the following is an observation and not an inference?
A student is conducting an experiment to determine how far a ball will roll down a ramp based on the angle of incline.
The angle of incline is the independent variable, and the distance the ball rolls is the dependent variable. Other conditions should be kept constant.
How is a scientific law different than a scientific theory?
A scientific law describes what consistently happens in nature, while a scientific theory explains how or why something happens. Both are supported by evidence.
What is the difference between an observation and an inference?
An observation is information directly gathered through the senses or measuring tools, while an inference is a conclusion or interpretation based on those observations.
A student is conducting an experiment to determine how far a ball will roll down a ramp based on the angle of incline.
The angle of incline is the independent variable, and the distance the ball rolls is the dependent variable. The ball, ramp, and other conditions should be controlled.
A dependent variable is
Explain how the first three steps of scientific inquiry are related.
Observations provide information that leads to questions. A question can then be used to form a testable hypothesis that predicts what will happen.
