Asking Scientific Questions

Asking questions is a vital part of the scientific process, but it’s not enough to simply ask any question. Science is about asking good questions that can be answered through direct observation or w/ scientific tools. While initially observing a phenomena, you should identify variables (things that you can change in order to change what you are observing). Scientific questions seek to determine the relationship between variables through experimentation or investigation. The answers to scientific questions are the results of experiments and investigations and DO NOT rely on beliefs, biases, wishes or desires. SCIENCE RELIES ON FACTS!
