Experimental Design
Levels of Organization
Scientific Method
100
The organ systems of an organism are in the perfect order to function.
What is order?
100
An organism physically adapts to survive in its conditions and surroundings.
What is evolutionary adaptations?
100
Something that is supported by a broad range of observations, experiments, and data.
What is theory?
100
The smallest level of organization.
What is atom?
100
The first step to the scientific method.
What is observation?
200
DNA which stores genetic code determines the physical traits of organisms.
What is genetic inheritance?
200
Living systems reproduce by either splitting itself into two or a sperm fertilizing an egg.
What is reproduction and development?
200
The variable that is measured and affected during the experiment.
What is dependent variable?
200
The largest level of organization.
What is biosphere?
200
The last step of the scientific method.
What is conclusion?
300
Outside sources are used to cause chemical reactions which create energy.
What is acquisition of materials and energy?
300
Organisms have appropriate complex responses to their environment helping them to survive.
What is response to stimuli?
300
The test group is exposed to this variable that deliberately changes.
What is experimental/independent variable?
300
Level of organization that consists of the organism and its community and surroundings, and other communities and surroundings from separate regions.
What is ecosystem?
300
When many experiments and observations support a theory.
What is scientific theory?
400
The systems within an organism must be at appropriate levels in order to survive.
What is regulation of internal environment?
400
How hawks have adapted to their way of life.
What is answers may vary (hollow bones for flight, sharp claws to catch prey)
400
An explanation that can be tested and begins with if...then...
What is hypothesis?
400
The union of two or more atoms.
What is a molecule?
400
A group of subjects that remain the same during the experiment in order to compare results.
What is control group?
500
How the liver maintains homeostasis.
What is when the organism hasn't eaten the liver releases stored sugar to keep blood sugar levels up.
500
One common scientific theory.
What is cell theory, gene theory, and/or evolution
500
Self-contained part of an organism that has a specific vital function to that organism.
What is organs?
500
The amount of experiments it takes for a hypothesis to be proven true.
What is a hypothesis can never be proven completely true?
