PURPOSE

• What you would like to find out.

?
4
PURPOSE

• Babies go through a lot of diapers each day
  and there are so many types of diapers to choose
  from. We would like to find out if a certain
  brand of diaper would hold more liquid than the
  others. Knowing this might help us to choose
  which type of diapers to buy.

5
Research

• Use your library, the internet, or ask an expert
  to find out all the information you can about
  your topic.

6
QUESTION

• What are you going to test?

7
QUESTION

• Do Luvs, Dri-Bottoms, or Pampers diapers
  absorb more liquid?

8
HYPOTHESIS

• Educated guess What do you think is going to
  happen?

9
HYPOTHESIS

• We think that Pampers will absorb the most
  because they cost the most.

10
MATERIALS

• List all the things needed to complete your
  experiment.
• Use METRIC measurements.

11
MATERIALS

• 3 jumbo size Luvs diapers
• 3 jumbo size Dri-Bottoms diapers
• 3 jumbo size Pampers diapers
• Measuring Cup
• Water

12
PROCEDURE

• Step by step plan
• Exactly what you will do to test your hypothesis.
  Collecting data and recording observations.
• Controls and variables

13
PROCEDURES

1. Pour one cup of water into the center of each
   diaper.
2. Check for any leaks.
3. Pour a second cup of water into the center of
   each diaper.

14
RESULTS

• Graphs, charts, or diagrams
• The outcome of your experiment is shared through
  daily logs, journal
• entries, graphs, charts, and drawings. 
• A log of the step-by-step procedure with any
  data collected could be in a notebook or folder
  which is placed in front of the project.

15
CONCLUSION

• In this section you will interpret your findings
  and results. Refer back to your purpose and
  indicate whether or not your findings support
  your hypothesis.

16
Demonstration, Model,
Experiment

• Whats the difference?

17
Demonstration

• A Demonstration
• Explains a device, scientific principle, or fact.
  
• Has a result that is already known.
• Does not require you to make measurements or
  observations.
• Does not have a variable

• Show what happens to a white carnation if you
  put it in colored water.

18
Experiment

• A Science Experiment
• Begins with a question that you dont know the
  answer to.
• Only one thing (variable) is tested while
  everything else remains the same.
• Requires something to be measured.
• Requires you to make and record careful
  observations.
• Has a conclusion that comes from your results and
  observations.
• Begins with a question that you dont know the
  answer to.

• Try the above demonstration with colored water of
  different temperatures.
• Example Question
• Will warm colored water change the
  carnations color faster?
• ice water warm water

19
Model

• a small copy of something
• details of how something is designed

20
Testable vs Un-Testable

• Testable
• Something can be observed.
• Something can be measured.
• Two or more things can be compared.
• Common materials found at home or school can be
  used for testing.

• Un-testable
• Equipment needed for testing would be too hard to
  get.
• Testing might be unsafe.
• Question is too complex to investigate at home or
  school.

21
Testable or Non-TestableYou Decide

• Which ice cream melts the fastest?
• Which car produces the most pollution?
• What coating keeps apples from browning?

22
Finding a Science Fair Project Idea

• Use your experiences Remember a time you
  noticed something and thought "I wonder how that
  works?" or "I wonder what would happen if..."
  then turn that into a project.
• Check the science section of the school library.
  Think about current events. Look at the
  newspaper. People are hungry in Africa because of
  droughts - a project on growing plants without
  much rain, which types grow ok with little water?
  Watch commercials on TV. Test their claims.
  Does that paper towel really absorb wetness
  better than other ones?
