True or False: Scientific theories are guesses.
False.
What makes a scientific explanation reliable?
Evidence from repeated investigations.
Explain one difference between a law and a theory.
Laws describe patterns; theories explain why those patterns occur.
Why are theories considered reliable?
They are supported by extensive evidence and testing.
Can scientific theories change? Why?
Yes, when new evidence becomes available.
Can scientific laws change?
Yes, if new evidence shows they are incomplete or inaccurate.
What is meant by predictive power in science?
The ability to accurately predict future observations or results.
Why are scientific models useful?
They simplify complex systems and help make predictions.
