Asking a scientific question

Asking a scientific question

Explanation:

Scientific inquiry is using evidence from observations and investigations to create logical explanations and answer questions. Scientific inquiry is for people who want to be challenged and use creative and critical thinking to answer questions related to science.

The scientific method has five basic steps;

1. Ask a Question (just like the research student asking which is a better fuel between ethanol and gasoline)

2. Do Background Research

3. Construct a Hypothesis

4. Test Your Hypothesis by Doing an Experiment

5. Analyze Your Data and Draw a Conclusion
