1. The Effects of Aluminum Foil On Baking a Potato By: Jacob Morgan Erin Reed

2. Experimental Question What effect does Aluminum foil have in the baking of a potato? What effect do the different sides of Aluminum foil have?What effect do the different sides of Aluminum foil have?

3. Experimental Design Temperature of Oven set to 350 F. Temperature of Oven set to 350 F. 3 potatoes tested at a time.3 potatoes tested at a time. 1 potato wrapped with shiny side of foil out1 potato wrapped with shiny side of foil out 1 potato wrapped with dull side of foil out1 potato wrapped with dull side of foil out 1 potato with no foil1 potato with no foil Temperature of center of Potato measured at varying time intervals. Temperature of center of Potato measured at varying time intervals.

4. Results

5. Results Average time to cook (180 F) Average time to cook (180 F) –No Wrapping - 42 minutes –Shiny Side Out – 49 minutes –Dull Side Out – 48 minutes

6. Discussion of Results Dull side out cooks the slowestDull side out cooks the slowest Initially at the highest rate, the cooking process slows down as heat flux due to radiation decreases.Initially at the highest rate, the cooking process slows down as heat flux due to radiation decreases. Wide range of differences with foil, due to finlike properties that occurredWide range of differences with foil, due to finlike properties that occurred Initial testing showed that the surface area of foil used had a large impact on heat flux.Initial testing showed that the surface area of foil used had a large impact on heat flux. If large amounts of aluminum foil were used (roughly 3 times what would normally be used) then cooking rates increased.If large amounts of aluminum foil were used (roughly 3 times what would normally be used) then cooking rates increased. Uncertainty also due to difference in Potato volume.Uncertainty also due to difference in Potato volume. No two potatoes are the same.No two potatoes are the same.

7. Conclusions Don’t cook with Aluminum Foil Don’t cook with Aluminum Foil The unwrapped potato cooks fastestThe unwrapped potato cooks fastest (Jacob couldn’t taste a difference)(Jacob couldn’t taste a difference) And buy Chevron Gas, it is the best gas in the world And buy Chevron Gas, it is the best gas in the world
