it)
Scientific Method Detailed Notes

(specific prediction)
Scientific Method Detailed NotesIII. Writing A HypothesisEX: If (the number of twirls) is related to (mass

effect)• Turn to your Glossary to letter “D”.• Add the words “dependent variable” and the
page number of your “Scientific Method Detailed Notes” (probably page 22)
Scientific Method Detailed NotesVariables related to an experiment:5. Independent Variable (I. V.) – manipulated/changed variable, cause (as in
cause and effect) (the one that I, as the experimenter, can change or control)

number of your “Scientific Method Detailed Notes” (probably page 22)
Scientific Method Detailed NotesIV. Write a Procedure
B. Short, easy to follow steps (sketches are good to include)
C. Each step begins with a verb (action word)D. Must be detailed enough so that someone
else could repeat your experiment.
Scientific Method Detailed NotesV. Carry Out (Do) the Experiment
• Now pick 3 crayons of different crayons from the bag.
Scientific Method Detailed NotesVI. Collect and Organize Data
A. Creating Data Tables1. Organize data in columns
and rows.
**Use 1 crayon to color 1 column and 1 row.
Scientific Method Detailed Notes• Turn to your Glossary to letter “D”.• Add the words “data table” and the page
number of your “Scientific Method Detailed Notes” (probably page 22)
Scientific Method Detailed NotesVI. Collect and Organize Data
A. Creating Data Tables2. Always have a title at the top of the
table.
Scientific Method Detailed NotesVI. Collect and Organize Data
A. Creating Data Tables3. Always put units (cm, g, etc.) in column
headings.
Scientific Method Detailed NotesVI. Collect and Organize Data
A. Creating Data Tables4. Usually, the Dependent Variable goes in
the right column and the Independent Variable goes in the left column.
**Use 2nd crayon to color “Dependent Variable” and D.V. column.
**Use 3rd crayon to color “Independent Variable” and I.V. column.

Scientific Method Detailed NotesVII. Analyze Data (Creating Graphs)• Turn to your Glossary to letter “A”.• Add the words “analyze data” and the page
number of your “Scientific Method Detailed Notes” (probably page 22)
Scientific Method Detailed NotesVII. Analyze Data (Creating Graphs)
A. There are three types of graphs:1. Line graph – continuous data (usually data over time)
Scientific Method Detailed Notes• Turn to your Glossary to letter “L”.• Add the words “line graph” and the page
number of your “Scientific Method Detailed Notes” (probably page 22)
Scientific Method Detailed NotesVII. Analyze Data (Creating Graphs)
A. There are three types of graphs:2. Bar graph – comparing data
Scientific Method Detailed Notes• Turn to your Glossary to letter “B”.• Add the words “bar graph” and the page
number of your “Scientific Method Detailed Notes” (probably page 22)

A. There are three types of graphs:3. Circle graph– percentage data (or parts of a whole)
Scientific Method Detailed Notes• Turn to your Glossary to letter “C”.• Add the words “circle graph” and the page
number of your “Scientific Method Detailed Notes” (probably page 22)

and the Dependent Variable goes on the y-axis.Choose 2 crayons. Color “The Independent
Variable goes on the x-axis” one color and color “the Dependent Variable goes on the y-axis” the second color.
Scientific Method Detailed NotesVII. Analyze Data (Creating Graphs)C. Every graph must have:
1. Title2. X-axis labeled 3. Y-axis labeled
Scientific Method Detailed NotesVII. Analyze Data (Creating Graphs)C. Every graph must have:
4. Appropriate intervals – must start at 0 and go up by the same amount each time
5. Appropriate type of graph for the data you are displaying
Scientific Method Detailed NotesVII. Analyze Data (Creating Graphs)C. Every graph must have:
X-Axis Label
Y-Ax
is La
bel
Color the x-axis one color and color the y-axis the second color. Use the same colors
Scientific Method Detailed NotesVII. Analyze Data (Creating Graphs)D. Interpolation vs. Extrapolation1. Interpolation – making a prediction based
inside the dataTurn to your Glossary to letter “I”.Add the word “interpolation” and the page
number of your “Scientific Method Detailed Notes” (probably page 22)
Scientific Method Detailed NotesVII. Analyze Data (Creating Graphs)D. Interpolation vs. Extrapolation1. Interpolation – making a prediction based
inside the dataa. For example, on the following graph
there is no specific data for 12 minutes, butwe can estimate what it would be becausewe have data between 10 and 15 minutes.
Interpolationthere is no specific data for 12 minutes
Scientific Method Detailed NotesVII. Analyze Data (Creating Graphs)D. Interpolation vs. Extrapolation2. Extrapolation – making a prediction that lies
outside the data• Turn to your Glossary to letter “E”.• Add the word “extrapolation” and the
page number of your “Scientific Method Detailed Notes” (probably page 22)
Scientific Method Detailed NotesVII. Analyze Data (Creating Graphs)D. Interpolation vs. Extrapolation2. Extrapolation – making a prediction that lies
outside the dataa. For example, on the above graph there is
no data for 3 minutes or for 35 minutes.
Scientific Method Detailed NotesVII. Analyze Data (Creating Graphs)D. Interpolation vs. Extrapolation
If we estimate for these times it would be extrapolation because we don’t have datathat those number lie between. They lieoutside of our data or they are “extra.”
Extrapolationthere is no specific data for 3 minutes or 35
minutes
Scientific Method Detailed NotesVIII. Draw Conclusions (Writing A Conclusion)• Turn to your Glossary to letter “C”.• Add the word “conclusion” and the page
