Hypothesis	The first floor of Timber Ridge Magnet School will produce the most airborne particles because doors are opening and closing and letting particles in.
Abstract	My question for the science fair is" Which Floor of Timber RidgeMagnet School has the Most Airborne Particles?" I choose this question because I have always wondered what I was breathing, and what floor of the school makes me sneeze.  I think that the first floor of Timber Ridge Magnet School will have the most airborne particles.  The reason I say this is because the door is opened down stairs and it lets more particles in. First, draw large circles on both sides of each index card with your compass.  Then, make a hole at the top of your cards with a hole puncher and connect your paper clips in the holes.  Next, you must tie the strings on to the paper clips and then smear the petroleum jelly on the circles. After that, you have to write the lettered labels on each card so you know weather a card is upstairs or downstairs.  Then, tape the end of the strings onto the ceiling 4 upstairs and 4 downstairs for 4 days.  When you have finished the first batch observe them with a the with the magnifying Last, you must keep all of your cards in a plastic bag to keep them preserved. My results found that the first floor of Timber Ridge School has the most airborne particles.  My hypothesis was right and I think it happened because the movement of kids and the constant opening and closing of doors. This is good information because you will know it is better to be on the second floor of a building.
Materials	1) 32 7-by-12.7 cm. index cards 2) pencil  3) 32 paper clips  4) 32 pieces of string  5) 32 pieces of tape  6) compass  7) petroleum jelly  8) 32 plastic bags  9) magnifiying glass  10) hole puncher  11) scissor
Procedure	1)  Draw  large circles on both sides of your index cards with your  compass.  2)  Make a hole at the top of your card with a hole puncher.  3)  Connect the paper clip so it is coming out of the hole in the card,   and tie the string onto the paper clip.  4)  Smear petroleum jelly on both sides of the card inside the circles.  5)  Write the letter in which the card is, a b c or d and write (u) for   upstairs or (d) for downstairs.  6)  Tape the string to the ceiling in four different places on that floor.  7)  At the end of the day use the magnifying glass to observe the number  of particles in the circle of the card.  8)  Repeat this steps for 4 days.  9)  After every time you record results make sure your cards are safe in a  plastic bag .
Results	Number of Particles  DAY 1:                  Day 2:  Upstairs               Upstairs  A-3                          A-7  B-2                          B-2  C-6                          C-2  D-4                           D-10  Downstairs         Downstairs  A-1                         A-2  B-2                         B-6  C-3                         C-1   D-2                         D-7    |  DAY 3:               DAY 4:   Upstairs            Upstairs  A-8                      A-3  B-4                      B-2  C-4                      C-2  D-4                      D-1      Downstairs       Downstairs  A-3                       A-7  B-5                      B-1  C-10                   C-3  D-4                      D-10
Conclusion	In my results I found that the first floor has the most airborne particles.  This conclusion is the same as my hypothesis, but I have another reason why this happened. It happened because there is more movement and people to spread particles on the first floor.  In the real world this conclusion is useful so you know upstairs positions in a building are better for people with allergies.
