1

Define Biology

Science that deals with the study of life

2

Define Science

A process used to solve problems or develop an understanding of repetitive natural events that involves the accumulation of knowledge and the testing of the possible answers

3

A way of gaining information about the world by forming possible answers to questions, followed by rigorous testing to determine if the proposed explanations are supported by the facts

Scientific Method

4

What are the basic assumptions of science?

-There are specific causes for naturally reoccurring events
-The causes for events can be identified
-General rules can be used to describe nature
-A repeatable event probably have the same cause
-Observable by many
-Same fundamental rules of nature apply regardless of when or where

5

Describe cause and effect relationships

When an event occurs as a direct result of a previous event

6

Complete the following sentence
The Scientific method involves an orderly, careful _____ for ______

The scientific method involves an orderly, careful SEARCH for INFORMATION

7

Checking and Rechecking are involved in what?

The scientific method

8

What are the components of the scientific method?

-Careful observation
-Constructing and testing of hypothesis
-An openness to new information and ideas
-A willingness to submit one's ideas to scrutiny of others

9

How do we make an observation

through smell sight hearing taste touch

10

What is an extension of observation?

microscope sound recorder x ray machine thermometer

11

A statement that provides a possible answer to a question

Hypothesis

12

What are the characteristics of a hypothesis

-Must be logical
-Must account for all the relevant information available
-Must allow for one to predict future events relating to question
-Must be testable

13

What is validity?

Able to be justified; on target

14

Explain what an experiment is

a recreation of an experiment that allows a scientist to prove or disprove a hypothesis

15

Many separate factors are

Variables

16

When one variable experiment is present it is known as

controlled experiment

17

A _____ group is a group in which there is no manipulation of the variable

CONTROL group

18

An Experimental group is defined as?

A group in which a variable is manipulated

19

_______ variable is expected to change as a direct result of the manipulation of the independent variable

Dependent Variable

Independent variable is

The variable that is manipulated

21

Another word for reliable

trustworthy

22

What is inductive reasoning?

Process of developing general principles from the examination of many sets of specific facts

23

Deductive reasoning is?

The process of using general principles to predict the specific facts of a situation

24

Define scientific theory

Widely accepted, plausible, general statement about fundamental concepts in science that explain why things happen

25

A uniform or constant fact of nature that describes what happens in nature

Scientific law

26

What is the difference between scientific law and theories

Scientific laws describes what happens and theories describe why things happen

27

A deceptive practice that uses the appearance or language of science to convince confuse or mislead people into thinking something has scientific validity
