five pennies, five dimes, five, five nickels, five quarters, five containers, 1/2 cup of vinegar, and one teaspoon of salt.

Procedure:
First set out out four containers,
Put four pennies in the first containers, Put four nickels in the second containers, Put four dimes in the third containers, Put four quarters in the fourth container, fill each container with 1/2 cup of white vinegar and 1/2 teaspoon of salt, leave the coins in the containers for sixty seconds, After the sixty seconds take the coins out form their containers, Write down your observations and your conclusion. ]]> 2018-04-26 01:28:19 UTC https://padlet.com/gallicha25/6e4yx5ovubu1/wish/255479966 Observations gallicha25 https://padlet.com/gallicha25/6e4yx5ovubu1/wish/255479977 When I mixed the salt and the vinegar the container became foggy then the salt settled and the container bacme clear. 
During the sixty seconds I could see the salt and vinegar eating away at the dirt and rust on the coins. 
When I took the coins out I didn't see much of a difference except the pennies top coat got messed up.  ]]> 2018-04-26 01:28:26 UTC https://padlet.com/gallicha25/6e4yx5ovubu1/wish/255479977 Conclussion gallicha25 https://padlet.com/gallicha25/6e4yx5ovubu1/wish/255479990 In the end I was wrong about my hypothesis because the quarters clean the best then the dimes then the nickels and lastly the pennies.]]> 2018-04-26 01:28:31 UTC https://padlet.com/gallicha25/6e4yx5ovubu1/wish/255479990
