Biology:
The Study of LIFE
What do these have in common?
They are biology!!! Biology is They are biology!!! Biology is the study of life!the study of life!
What is a Biologist?Someone who studies biology
(living things)When you are in this class you are studying living things…YOU ARE A BIOLOGIST!
What makes a living thing living?
Characteristics of Living Things…1. orderly structure are
organized and made of at least one cell
2. reproduce produce offspring3. grow increase in the amount
of living material and develop all of the changes that take place during the life of an organism
Characteristics of Living Things… 4. adjust to changes in the
environment maintain homeostasisexample- shivering to stay warm
5. adapt (any inherited structure, behavior, or internal process that enables an organism to respond to environmental factors and live to produce offspring) and evolve (the gradual change in a species through adaptations over time)
Characteristics of Living Things… In order for something to be living it
must demonstrate allall of the characteristics of living things…An organism is a living thing
So…is it living, nonliving, or dead?
So, is it living, nonliving, or dead?Living (biotic)- Demonstrates all five characteristics of living things
So, is it living, nonliving, or dead?
Nonliving (abiotic)- Does not demonstrate ALL five of the characteristics of living things (may demonstrate some of them)
So, is it living, nonliving, or dead?
characteristics of living things at one time, but… does not currently do so.
Scientific Method
Common steps scientists use to gather information and answer questions.
There are no set order to the steps
Usually begins with asking a question or solving a problem
Hypothesize:Make a prediction in the form of “if…then…because…”
Experimenting…investigating
A controlThe part of an experiment that is the standard against which results are compared
Experimenting…investigating
Independent variableThe condition in the experiment that is being changed
Experimenting…investigating
Dependent variableThe condition that is being observed/measured during the experiment
AnalyzeOrganize data into a chart or
graph
Report the results
Conclusion
Observing… Gathering DataTwo types of data
QualitativeDescriptions such as color, behavior, etc
QuantitativeNumerical measurements such as time, height, mass, etc.
Theory vs. Law
A theory is an explanation of a natural phenomenon that is supported by a large body of scientific evidence obtained from many different investigations and observations.Ex. Big bang theory
Theory vs. Law
A law is a natural phenomenon that is generally known to be true.Ex. gravity
Science and Ethics Ethics- moral principles and values held
by humans
Science cannot answer all questions Good vs. evil Ugly vs. beautiful
Technology is the application of scientific research to society’s needs and problems
