Scientific Method test
hypothesis
a explanation for a question or a problem that can formaly be tested
scientific method
a logical approach to scientific problem solving
conclusion
a statement of whether or not the result from the experiment support the hypothesis
quantitative observation
a type of observatio recording measurements hoe much of it mass length volume density time rate temperature
theory
an explanation of a natural phemomenon that is supported by scientific evidence a hypothesis is that has withstood reapeatd testing of a period of time.
Graphs
are important to show the relationshio between the independent variable and the the outcome(dependent variable)
inferences
assumptions that are made form observations and data collected
step 6 of scientific method
conclusion
if
condition
step 4 of the scientfic method
experiment
because
explanation
step 5 of scientific method
gathering and recording data
step 3 of the scientific method
hypothesis
step 2 of scientific method
state the problem
dependent variable
the changes that occured as a result of the independant variablethe result of the change ex. plant dies, plant wiltsm plants loses leaves, leaves turn yellow or brown
independant variable
the factor being tested it it the one that affects the out come of the results of the experimentthe one thing that has been changedhe factor that is being tested. It i the one factor that afftects the outcome of the results of an experiment
control group
the group that has all the normal conditions and the outcome is known
control group
the group with normal conditions where the outcome is KNOWN
experiment
the procedure that tests the hypothesis by the process of collecting information under controlled conditions
experimental group
the test group
experimental group
the tst grup it has all the same conditions except for the one factor being tested
step 7 of the scientific method
theory
law
true 100% of the time
a qualitatitive observation
type of observation descriptive traits smell color shape sound location taste
observation
using 5 senses to examine environment
observation
using as many senses to gather information about a particular situation
controlled variables or constants
what remains the same between two groups ex: same type of flower, same amount of soil, same amount of water, same size pot
Inferences
ARE MADE FROM OBSERVATIONS AND DATA IS COLLECTED SO YOU CAN MAKE A CONCLUSION
