|
Independent Varible
|
the values of the _____ variale vary at regular intervals
the values are known from the start of th experiment |
|
|
Dependent Varible
|
the values are not know at the start of the experiment
the values may or may noy vary at regular intervals you DESCOVER the value during the experiment |
|
|
Direct Relationship
|
as X increases, Y increases
|
|
|
Inderect Relationship
|
as X increases, Y decreases
|
|
|
No Realationship
|
as X increases, B stays the same
|
|
|
Cyclic Relationship
|
as X increases, Y increases and decreases in a regular pattern
|
|
|
State the Problem
|
consider the information available and state the problem in the form of a question
what is the ralationship between the independent variable and the dependent variable |
|
|
Reasearch (part of the introduction)
|
what do we know about the problem?
what do we need to know about the problem? where can we locate this imformation? |
|
|
Hypothesis
|
based on the information we have avalible, suggest an answer to the problem question
an educated guess which answers the problem question. as the independent varible increases the dependent variable increases |
|
|
Procedure
|
the procedure should be writen in a step by step formation. give directions how to do the experimient.
develop an experimental design to test your hypothesis choose the independent and the dependent variables determine method of measurement be sure to include at least three trails |
|
|
Data and Observations
|
an observation is what you notice about something (5 sences)
prepare a Data Chart to record your measurements (includes independent and dependent variables and units) choose an approprite graph to illustrate your data (line, bar, circle) |
|
|
Conclusions
|
do the results of your experiment support or refite your hypothesis?
what are some of the sources of error in your experiment? how could your experimental design and lad techniqe be improved? |
|
|
Introduction
|
the intro should include background info about the topic to tell the reader what the lab experiment is about.
|
|
|
Infrence
|
a judgement on the basis of observation
|
