1

what is science

a collection of knowledge and a process of discovering how various parts of the universe interact with each other

2

Physics

is the study of forces and energy.

3

Chemistry

the study of atoms and molecules, their structures, and their interactions to form various substances

4

Earth science

Earths structure and composition, as well as the process that change earth such as volcanic and seismic activity.

5

physical science

studies non-living organisms
(earth science, chemistry, physics)

6

life science

studies living organisms

7

Atoms

extremely small particles that make up All living and non-living things. Atoms are so small they cannot be seen with an ordinary microscope. when these particles bond together they make a wide variety of molecules.
Atoms and molecules make up every substance we know.

8

variables

changing quantities in an experiment

9

dependent variable

the one that changes because of the independent variable

10

independent variable

is the one that is being changed or controlled by the experimenter

11

control(constant) variable

the variables that need to be either eliminated or kept constant (these are not being studied)

12

controlled study

an independent variable (the cause) is systematically manipulated and the dependent variable (the effect) is measured; any extraneous variables are controlled.

13

observational study

can be done with our own senses (sight, hearing, smell, taste, or touch) or by using tools (telescopes, radiation detectors, multimeters, etc.).

In observational studies, the systems are observed as they appear in nature and researchers do not attempt to change them.

14

field study

collection of raw data outside a laboratory, library, or workplace setting. The approaches and methods used in field research vary across disciplines.

15

physical model

is a smaller or larger physical copy of an object used to study the larger scale.

16

conceptual models

can be used to visualize things that cannot be seen, such as atoms.
The main goals of a conceptual model are to capture the essential features of the system that it represents and to be easily understood by those who use the model.

17

mathematical models

treat physical objects or phenomena using mathematical methods. In these models, pertinent physical characteristics are represented using formulas, graphs, or other mathematical means.

18

principle of falsification

for a theory to be considered scientific it must be able to be tested and proven false.

19

hypothesis

an educated guess or prediction that might explain a phenomenon.
- is based on real data with little supporting evidence.
- relies on the principle of falsifiability.

20

scientific law

A law is a concise statement based on many experiments or observations.
- supported by all data and observations
-descriptions of natural phenomena
-generally rely on a mathematical equation

21

Theory

is a statement that explains a wide range of observations and that is supported by a large body of scientific evidence. It explains how and why things happen
