Chemistry Chapter 1.1 - the central science

chemistry

the study of matter and the changes it undergoes OR the study of the interactions of matter with other matter and with energy

matter

anything that is physically real and can take up space

why is chemistry central to other sciences?

it joins together physics and math, biology and medicine, and earth and science

what is the language of science and what is it used to do

math is the language of science and it is used to communicate concepts in chemistry

knowledge of chemicals and chemical processes provide what

insights into a variety of physical and biological phenomenons

science

the process by which we learn about the natural universe by observing, testing, and then generating models that explain our observations

model

a workable explanation, description, or representation of a phenomenon

what does the process or the action of science overlap

scientific method

scientific method

the general processes by which we learn about the natural universe

scientific method (simplified)

propose a hypothesis, test the hypothesis, and refine the hypothesis if necessary

why do we make observations

to collect data which leads to questions and hypothesis

hypothesis

a supposition or proposed explanation made on the basis of limited evidence as a starting position for further investigation

quantitative data

the numbers and statistics

qualitative data

words used to describe

why do we test data

to find patterns and make predictions

why do we used deductive and inductive reasoning

to connect the data to make predictive

deductive reasoning

comes from general statements (premises) to specific conclusions

inductive reasoning

known data to unknown general conclusion; cannot prove conclusions but rather shows probability based on other evidence

what is explained when data is collected and reviewed consistently

the phenomenon being tested, it becomes a theory

theory

a carefully thought-out explanation for observations of the natural world that has been constructed using the scientific method and which brings to many facts and hypothesis

when does a theory become a law

when it has been tested by the scientific community

law

a statement that recognized and repeating pattern in nature; laws often take the form of a mathematics equation
