Graph preferred by scientists.
a line graph
retesting
What is the dependent (responding) variable?
The variable you measure (depends on the IV)
How is a theory different from a law?
Laws are universally accepted.
What is the difference between an inference and evidence?
inference is an educated guess and an observation is fact.
What are the controlled variables?
the variables that are held constant between the two test groups.
What can render an experiment invalid?
No control
Multiple independent variables
How is the scale determined for the graph?
the highest value needed/number of spaces available
defined as heterotroph
eat different things
How does the data table relate to the graph?
the I.V. is the x-axis and the D.V. is the y-axis or the data table is the information you graph
Defined as below temperature.
hypothermia
One piece of information that must be present on all graphs?
title
units
labels for the x and y axis
equal scale for each axis
key
What is the difference between the control group and the controls.
the control group is a test group kept in normal conditions and the controlled variable(s) are the controls that are held constant (the same) between the two test groups.
Identify the independent variables in the following scenario:
Mrs. Zukowski noticed that she does not get dry skin in the winter when she puts olive oil on her hands. She wants to test olive to see if it makes a difference.
Olive oil = I.V.
Write a hypothesis for the following information:
Plant
Height in Centimeters
Red light
If you grow a plant in red light then, it will increase in height, because plants can best absorb red wavelengths of light.
Defined as dermatitis
Inflammation of the skin.
defined as photosynthesis
to make with light
The 3rd step of the scientific method
perform an experiment/gather data
