What are the three factors needed for a question to be scientific?

1. Verification questions - These are basic data collecting questions. They are useful in building knowledge.Examples are: Is it cold today? Is the sun still out? Is a flame hottest when it is blue?2. Significant/Theory questions require an explanation and prior knowledge - Examples are: Why should you point a car's wheels toward the curb when parking on a hill? Do clouds have to be in the sky for it to rain? Why do you add acid to water instead of water to acid? These questions increase knowledge of the subject, but need prior knowledge to be asked3. Experimental questions require explanations, prior knowledge, and are testable - Example: If salt is added to water, would the solution still boil at the same temperature? or If Suntan lotion is put on ultraviolet detecting beads, will the beads still change color? Experimental questions require a more in depth answer that requires testing. Experimental questions are what researchers use.


What two theories or questions that science currently working on?

It depends on which branch of science you are interested. Medical science is working on cancer, physicists are looking for the Higg's boson, meteorologists are trying to understand global climate change...


Do chemical reactions that increase entropy tend to occur spontaneously?

Reactions that increase the randomness. Reactions that have more moles of gas on the product side than the reactant side increase entropy. Also reactions that have a positive change in spontaneity and a negative enthalpy.
