Scientific Method Concepts

The video tutorial explains the biological method, detailing the steps from observations to scientific laws. It covers how observations can be qualitative or quantitative, the formulation of hypotheses through deductive and inductive reasoning, and the rigorous testing of these hypotheses through experiments. The video further explains how a series of well-supported hypotheses can lead to a theory, which, if consistently supported by evidence, becomes a scientific law. The tutorial concludes with examples of scientific laws in biology.

What is the first step in the biological method?

• Hypothesis

• Experiment

• Observation

• Theory

Which of the following senses is NOT used for making observations?

• Vision

• Hearing

• Smell

• Telepathy

What type of observation involves measuring quantities?

• Qualitative

• Quantitative

• Subjective

• Descriptive

What is a hypothesis?

• A tentative explanation

• An untested theory

• A proven fact

• A scientific law

Deductive reasoning moves from:

• Hypothesis to theory

• Specific to general

• General to specific

• Theory to law

What is the purpose of testing a hypothesis?

• To create a law

• To prove it wrong

• To gather data

• To accept or reject it

A well-supported hypothesis that is not falsified becomes a:

• Theory

• Fact

• Observation

• Law

What characteristic is important for a good theory?

• It is simple

• It is always correct

• It suggests new hypotheses

• It is irrefutable

What is a scientific law?

• A hypothesis

• A theory

• A constant fact of nature

• An observation

Which of the following is an example of a biological law?

• Darwin's Hypothesis

• Mendel's Law

• Einstein's Theory

• Newton's Law
