What are theories in science?

Scientific theories are like blueprints for understanding the world. They guide us in making predictions and conducting experiments to test our ideas. Think of them as a framework that holds everything together.

What is a hypothesis?

Hypotheses are specific, testable predictions based on existing theories. They are like educated guesses that scientists can test using experiments.

What is deductive reasoning in science?

Deductive reasoning is like building a logical chain of thought, starting from a general principle (theory) and working down to specific predictions (hypotheses).

What is inductive reasoning in science?

Inductive reasoning uses specific observations to build a more general understanding. Scientists use it to refine existing theories or even develop new ones.
