Hypothesis stating that life could arise from nonliving matter
Spontaneous Generation
100
The scientific study of living things
Biology
100
Replication of Experiments
Reason for Common System of Measurement
100
Organized way of using evidence to learn about the natural world; also, the body of knowledge that scientists have built up after years of using this process.
Science
200
questions existing ideas and new hypotheses
What does it mean to describe a scientist as skeptical?
200
A test of the effect of a single variable by changing it while keeping all other variables the same
Controlled Experiment
200
States that cells are the basic structural and physiological units of all living organisms, and that all cells come from preexisting cells.
Cell theory
200
a decimal system of measurement whose units are based on certain physical standards and are scaled on multiples of 10
metric system
200
Use of one or more of the senses—sight, hearing, touch, smell, and sometimes taste—to gather information.
Observation
300
It involves the observation of anything that can be measured such as the differences in shapes, sizes, color, volume, and numbers.
What is the main difference between qualitative and quantitative?
300
Factor in an experiment that a scientist purposely changes; also know as independent variable
Manipulated Variable
300
Any gradual change. Most often refers to organic or Darwinian evolution, which is the genetic and resulting phenotypic change in populations of organisms from generation to generation.
evolution
300
1 kilometer
1000 meters
300
Evidence; information gathered from observations.
Data
400
a proposed explanation
What is a scientific hypothesis?
400
Factor in an experiment that a scientist wants to observe, which may change in response to the manipulated variable; also know as a dependent variable
Responding Variable
400
The contribution of offspring to the next generation by various genetic types belonging to the same population. The mechanism of evolution proposed by Charles Darwin
natural selection
400
When scientists collect data, they are often trying to find out...
whether certain factors changed or not
400
Logical interpretation based on prior knowledge and experience.
Inference
500
a scientific hypothesis must be testable; scientists continually evaluate the strengths and weaknesses of hypotheses; they are open minded and modify hypotheses if data deem it
Is a scientific hypothesis accepted if there is no way to demonstrate that the hypothesis is wrong?
500
Well-tested explanation that unifies a broad range of observations
Theory
500
The complete DNA sequence for a particular organism or individual.
genome
500
devices that produce magnified image of structures that are too small to see with the unaided eye
microscopes
500
Possible explanation for a set of observations or possible answer to a scientific question.
