Nature of Science
Details and information gained through experimentation and observation.
What are data?
Type of energy that gasoline contains before it is burned.
What is chemical potential energy?
The process by which organisms with favorable traits will survive and reproduce, increasing those favorable traits in a population.
What is natural selection?
The preserved remains or traces of living things.
What are fossils?
A model used by scientists to determine the properties of elements.
What is the periodic table of elements?
The variable that a scientist changes on purpose in an experiment.
What is an independent (test) variable?
A physical characteristic that remains the same for a pure substance, regardless of the sample size.
What is melting point?
What is boiling point?
Inherited characteristic that increases an organism’s chances for survival and reproduction in its environment.
What is an adaptation?
The type of rock in which fossils are found.
A state of matter with a fixed shape and a fixed volume.
What is a solid?
The group in an experiment or study that does not receive treatment by the researchers.
What is a control group?
This type of heat transfer involves materials that are in direct contact with one another.
What is conduction?
Any of two or more alternate forms of a gene that an organism may have for a particular trait.
What is an allele?
All the information that paleontologists have gathered about past life.
What is the fossil record?
A core of positive and neutral particles surrounded by negative particles.
What is the atom?
The variable that belongs on the y-axis (vertical axis) of a graph.
What is a dependent (outcome) variable?
The three subatomic particles that make up all living and nonliving things.
What are protons, neutrons and electrons?
Early stages of development in organisms in which there are many similarities (i.e. a chicken and human embryo).
What is comparative embryology?
What is embryological development?
Principle that could be used to date a stack of horizontal rock layers.
What is superposition?
What is the law of superposition?
A sudden change in the sequence of DNA that can bring new alleles to a population.
What is a mutation?
Variable that is constant and is unchanged in an experiment.
What is a controlled variable?
Average speed of a cyclist traveling 32 km in 2 hours.
What is 16 km/h?
A type of reproduction used by Cyanobacteria to produce genetically identical offspring.
What is asexual reproduction?
The age of our planet Earth.
What is 4.5 billion years old?
Changes in the allele frequency of a population over time.
What is evolution?
