What is required for something to become a scientific theory?
Multiple research projects proving it correct
What does a scientific theory explain?
Why something is true in the natural or scientific world
What happens if new evidence contradicts a scientific theory?

What is the main purpose of a scientific law?
To explain current phenomena
What distinguishes a scale model from a life-size model?
Scale models maintain proportional parts.
Why are simulations considered beneficial in scientific research?
They provide a safer means for testing dangerous scenarios.
Which of the following is a characteristic of conceptual models?
They provide a reference point for designers.
In what situations are physical models particularly useful?
When testing outcomes in dangerous scenarios
What distinguishes a scientific law from a scientific theory?
Laws can be disproven with new evidence, theories cannot.
How do models differ from simulations?
Models represent current states, simulations re-enact scenarios.
'A scale model must have parts that are proportional and of the same ratio.' This statement emphasizes the importance of:
'A scale model should maintain accurate proportions.'
What is the first step in conducting a simulation?
Identifying the scenario to recreate
Which organic molecule class is primarily responsible for genetic coding?
