Transcript of A ______________ is a testable explanation hypothesis.
Characteristics of Life & Scientific Method Review
A ______________ is a testable explanation
•hypothesis
The factor that you will change in your experiment is called the
_______________ variable
• Independent
___________________are the repetition of an experiment (trials) and the same conditions are kept in the
experiment.
•Replicates
An _______________ is a logical explanation based on
observations and experiences
• inference
What is the independent variable in the following
problem: How does clay soil effect plant growth?
•Clay soil
______________ is the ability to travel from place to place
• locomotion
What is the study of life?
•Biology
What would be a constant for the “ice cube” experiment
•Amount of salt used•Amount of water used•Size of cups• Temperature of the water•Size of the ice cube
A________________describes relationships under certain conditions
in nature; Describes but does not explain a natural event
• Law
___________________are inherited changes in structures, behaviors, or internal processes that enable an
organism to respond to stimuli
•Adaptations
The ______________ variable is what you predict will change as
a result of variation in your experiment
•dependent
____________ is the ability to do work or cause change
• energy
A __________ is a group that serves as a standard of comparison during an
experiment
•Control
In what format do you write a hypothesis?
• If…..then
What is the dependent variable in the following problem: How
does clay soil effect plant growth?
•Plant growth
A ____________ is a condition in the environment that creates a
response
• stimulus
What is the independent variable in the “ice cube” lab?
•Salt water
______________ are the factors that DO NOT change in the
experiment
•Constants
What is the dependent variable in the “ice cube” lab?
• Ice melting
The increase in living material (cellular mass) and the
formation of new structures is called _________
•Growth
A __________is an explanation based on many observations (hypothesis is repeatedly verified over time and
through may separate experiments)
• Theory
_______________ is the regulation of an organism’s internal environment to maintain conditions that allow it to
live
•Homeostasis
____________ is movement or gestures
•motion
The _____________________ is a continuous process that seeks to
answer questions about the natural world.
•Nature of science
___________ are the basic unit of structure and function of all
living things
•Cells
The steps commonly used by scientists in gathering
information to test hypotheses and solve problems are
called________• The scientific method
Observations and measurements made during an
experiment is called _____
•data
Humans sweating or shivering in order to maintain body temperature (thermal regulation) is an example
of which characteristic of life?
•Maintaining homeostasis
The changes that take place during the life of the organism
is called ___________
•development
