The hypothesis is that peanut residue will be present on the airplane seats.

You will categorize and color-code sterile swabs, prepare distilled water and phosphate buffered saline, and swab the seats, tray tables, and armrests.

You will need an America West "Airline A 319" Flight 820, an America West Airline "Airline A 319" Flight 805, an America West Airline "Airline A319" Flight 748, a Peanut Allergy Kit, 20 Sterile Swabs, 1 Liter Distilled Water, a packet of Phosphate Buffered Saline ph 7.4, Singer Electric Sewing Scissors, a Laboratory, 2 Fedex shipping boxes, Blue Ice, Air Sick Bags, Airline Tickets, Yellow Yarn, Light purple Yarn, Olive Green Yarn, Hot Pink Yarn, Colored Coded Markers, a Black Pen, a red Sharpie, Sticky Noted, a 4x4 Cardboard Cutout, a 2x8 Cardboard Cutout, a roll of Scotch tape, an Ice Chest, and 2 4 ounce containers.

The results showed that peanut residue was found on one airplane seat, but the amount was not likely to cause a severe reaction in a passenger with a known peanut allergy. This observation stands out because it shows that although peanut residue was present, it was not in an amount that would cause a severe reaction.

This science project is interesting and unique because it investigates the presence of peanut residue on airplanes and the potential for allergic reactions in passengers.

Experiment variations to consider include testing different types of snacks served on airplanes and testing for other allergens.
