Understand and be able to list the levels of biological organization.
Understand how they are organized in a hierarchy from simplest to more complex. - Atoms,
Molecules, Cells, Tissues, Organs, Organ Systems, Organisms, Populations, Communities, Ecosystems,
Biosphere
Be able to list the properties common to all living things. - Order, Regulation, Growth and
Development, Energy Usage, Response to Environment, Reproduction, Evolution; Have Cells and DNA
They are complex and organized; they grow and reproduce; they respond to stimuli; they acquire
materials and use energy (metabolism); they use DNA to store hereditary information; they have
adaptations to their environment.
Homeostasis - The process of keeping internal conditions such as temperature constant in an
organism
Be able to list the three domains of living organisms
and the basic type of organisms each domain contains - Domains:
Eukarya-Domain is made up of mostly multicellular organisms with eukaryotic cells.
Archaea-Domain is made up of single-celled organisms with prokaryotic cells prefer extreme
environments.
Bacteria-Domain made up of single-celled organisms with prokaryotic cells; can live everywhere.
Basic Type Organisms:
Prokaryotic or Eukaryotic
Understand and be able to list the steps of the scientific method using an example experiment. -
Observation, Question, Hypothesis, Prediction, Experiment, Results,
Example Experiment:
, ?
Hypothesis - Tentative, testable answer to a question, or an explanation on trial; very specific; not yet
been proven.
Experimental Variable - Group in an experiment that is/has the factor you are testing
Control Group - Group in an experiment that cancels out all other factors than the one being tested;
differs from experimental group in only one variable.
Know how hypotheses differ from theories. Be able to give an example of a scientific theory. - A
hypothesis is constructed before any applicable research has been done. A theory, on the other
hand, is supported by evidence: it's a principle formed as an attempt to explain things that have
already been substantiated by data.
Example:
Evolution, plate tectonics, and the Big Bang are all examples of scientific theories.
_______is a substance that can't be broken down into another substance by ordinary means. -
Element
Know the three components of an atom and their properties - Protons have a positive charge +
neutrons are neutral =
electrons have a negative charge -
Understand how electrons orbit around the protons and neutrons in the nucleus of the atom. - The
attraction between the negative charge of an electron, and the postive charge of the proton, is what
keeps the electrons in orbit around the nucleus.
Atomic Number - An element's atomic number equals its number of protons or electrons. Know that
an element's atomic mass equals its number of protons plus its number of neutrons.
Ion - Are atoms or molecules that are electrically charged as a result of gaining or losing electrons.
