The process of scientific inquiry
The scientific inquiry process is the method scientists use to explore observations and answer questions. It's a cycle of observation, questioning, hypothesizing, testing, and concluding.
Identify independent and dependent variables
In an experiment, the independent variable is the one you change, and the dependent variable is the one you measure. Think of it as 'I' change the Independent variable, and the Dependent variable 'Depends' on that change.
Identify the experimental question
The experimental question is the clear, specific, and testable question that an experiment is designed to answer. It often explores the relationship between the independent and dependent variables.
Identify questions that can be investigated with a set of materials
Given a set of materials, a good scientific question is one that can be answered through a controlled experiment using only those materials. It requires you to think like a scientist and design a testable investigation.
