VIRTUAL SCIENCE FAIR Karen Michelle Stewart

Science Content  Health, life & physical science  Concepts  Hygiene  Health  Prevention of sickness  How parts of the body work  Terms  Diaphragm  Muscle

Relation to Experiment  Why is this information important to the experiment?  Terms for parts of the body that a student may not know  Understand the importance of health  Understand how this relates to their life  Apply information to their own life

Narrative April 1st Researched new ideas for experiment Researched background information on topic April 5 th Began writing out procedures and brainstorming variables April 6th Bought supplies at the store

Narrative (cont’d) April 8 th Measured balloons to make sure they were the same size Checked for any blemishes in balloons Measured out confetti to have the same amount in each balloon

Narrative April 8 th Performed practice “pops” to determine best way to measure confetti spray. Cleaned up the mess :( April 9 th Carried out experiment

Materials  30 balloons  Bag of confetti  2 safety pins  Ruler  Graph paper/paper  Pencil  Measuring spoons  You and a buddy

Variables  Part of body used to block sneeze  Amount of ‘sneeze debris’ (confetti) that passes by part of body ManipulativeResponding Constants: Amount of air blown into balloon Shape of balloon Size of balloon Amount of confetti put into balloon Distance of balloon from elbow/hand Location where pin is used to pop balloon

Step 1- Ask a Question  What is the effect of covering your mouth with different body parts, on the amount of “sneeze debris” that gets past that body part?

Step 2-Background Research  Size of diaphragm?  What do the experts say?  Best way to cover sneeze?  Spreading of germs?  Ways to prevent?  Best practices…..

Step 3-Construct Hypothesis  I predict that using your hand to cover a sneeze will prevent “sneeze debris” from spraying, more so than the inside of your elbow.

Step 4-Test it!  2 people used for this experiment  Balloons are filled with 100 pieces of confetti  Blown up to size of diaphragm  Balloons popped near hand or elbow  Measurements taken/data collected  5 trials each body part

Step 5-Analyze Result/Draw Conclusion Manipulative12345TotalMeanMedianModeRange Elbow n/a10 Hand n/a6 Sneeze Debris (pieces) Trials of popping How much sneeze debris will pass through your arm and elbow?

Step 6-Communicate Results  My hypothesis was proven. Although the inside of an individual’s elbow and arm is larger than a hand, the hand is able to be cupped and moved easier to cover the mouth.

Real World Application  Pertains to Everyone!!!!  Always cover mouth when you sneeze  Wash hands often to prevent sickness and spread of germs  Understand how this relates to their life  Apply information to their own life
