 * Topic:** Pollution!


 * Problem:** does the location of pollution affect the amount?


 * Materials:**
 * 6 Styrofoam plates,
 * Petroleum jelly (Vaseline),
 * Wire ties


 * Procedure:**
 * 1) first I will smear a thin layer of petroleum jelly onto a Styrofoam plate.
 * 2) I will cut two holes onto the plate.
 * 3) I will set the plates up in different locations.
 * At Lawncrest park.
 * In my bedroom
 * In my front yard
 * In my back yard
 * In my car
 * Along Oakley and Passmore
 * 1) I will leave the plates out for 24 hours.
 * 2) I will take numerous photos and analyze data.
 * 3) I will repeat all steps again on a different day.


 * Hypothesis:** I think that the most pollution will be on Oakley and Passmore because of all of the cars passing. I think that the least polluted area will be in my back yard because it is not very close to the roads and no chemicals are used on my lawn.


 * Journal entries:**

· Sunday April 10, 2011: Today I will be going to the store to purchase petroleum jelly. I will begin my procedure by coating the plates with a thin layer of Vaseline. At about 12 noon I will set each of my plates out. In order to keep the plates in place i will use wire ties to secure them to a gate or fence. · Monday April 11, 2011: Today during lunch at about 12 noon I went go out to collect all of my plates because it is supposed to rain on Tuesday. i had to rip the edges of the plates so that the wire ties no longer held them in place. After I collected them I saw that the plate from my back yard was the second darkest behind the one on the corner of Oakley and Passmore. The one inside of my house was the lightest. From dardest to lightest this was the order: 1. Oakley and Passmore 2. my back yard 3. Lawncrest field 4. my front yard 5. my car 6. my bedroom

**Conclusion:** my hypothesis was correct. the one on the corner of Oakley and Passmore was where most pollution was found. this is because it is on a relatively buisy corner.
