• Hypothesis
• Introduction
• Materials Methods
• Results
• Discussion

Calisthenics 8/26/12

• U use scientific method everytime you meet
  someone. Science is really just a pursuit of
  knowledge. Think about yesterdays experiment.
  Other than a graph, what parts would you use on a
  first date?
• Parts
• Purpose
• Hypothesis
• Intro
• Materials and Methods
• Results
• Discussion

4
Purpose

• Answers the question, WHY am I doing this
  experiment?
• This is the whole reason why you are doing an
  experiment.
• Hint If you dont know the purpose, dont do the
  experiment.

5
Hypothesis

• Question- WHAT do I think will happen and WHY,
  Natedawg?
• Educated guess.
• Not eenie meenie minie moe!
• Hint At the end, you should be able to prove it
  True or False.

6
Introduction

• Question- WHAT do I know already?
• NOT what do you think.
• Introduces someone else to the important parts of
  your experiment.
• Hint Paragraph form.

7
Materials Methods

• Question- WHAT do I have and WHAT do I do?
• This part is easy and usually is given to you.
• Hint Read over before doing experiment.

8
Results

• Question- WHAT did I test?
• This part includes Graphs, Tables, and
  Observations.
• Hint Set up tables ahead of time to record
  quicker.

9
Discussion

• Question- WHY did I see what I saw?
• Most important part.
• Can suggest experiments or errors here too
  (paragraph form).
• Hint Back it up with facts.

10
Calisthenics (8/27)

• Write in slot 2 of your sheet.
• What is the average of the following set 76
  73 62 75
• What is wrong with the graph below?

D vs. T
Average
Time
Distance
11
Control

• Question- How do I know Im doing it right?
• You know what the outcome should be before you do
  it.
• to check or regulate
• a standard of comparison
• Hint Most experiments have one.

12

13
Independent Dependent Variables

• Questions-
• Which variable do I manipulate or change myself?
• Which variable am I measuring?

14
Independent Dependent Variables

• Independent (x-axis)
• The variable that is purposely changed
• i.e. time (it changes regardless of the
  experiment)
• Dependent (y-axis)
• Influenced by the independent variable.
• i.e. distance (when you walk, how far you go
  depends on how much time you have.

15
Graphing

• T.A.I.L.S.
• Title
• Be specific about what is in your graph
• Dont just write distance vs. time
• Axis
• Independent Variable (Y)Dependent (X)
• Interval
• Each grid line must change by the same amount
• Labels
• Concept and Unit
• Scale
• Did you use the entire space provided?

16
Graphing

• What is wrong with this picture?
• What is right with it?

17
Safety

• Question- AM I GOING TO BE OKAY?
• Right to Know Law
• Behavior
• Location of safety items.
• Hint Follow Instructions and You will be fine.
