In order to get the most reliable results in a scientific inquiry, it is important to be both precise and accurate in the collection of data.
Bias and errors can result in inaccurate results from an experimental inquiry.
An experimental inquiry typically has three main types of variables: an independent variable, a dependent variable and controlled variables.
When scientists have questions, they may perform tests or experimental inquiries to try to find the answers.
Even a well-planned experimental inquiry can include variability and errors beyond the experimenter’s control.
Before conducting the inquiry through testing and observation, students need to develop a scientific hypothesis.
Enabling students to design and carry out experimental inquiries is an important aspect of learning about scientific processes.
