Cleaning Coins Science Project Results

Experimental Procedure. Fill four cups each one quarter full with each of the six cleaning solutions suggested (4 with lemon juice, 4 with orange juice, 4 with cola, 4 with water, 4 with baking soda paste and 4 with dish liquid). Carefully record each coin's condition prior to placing it into its cup.
Try your hand at classic science with the cleaning pennies science experiment. Kids will be amazed at how this simple chemical reaction transforms pennies!
You're not done yet, though, lets try another experiment: Add more pennies to the bowl for 10 seconds, but this time , don't rinse them off. Place them on a paper .
Did you know that most coins circulate for about 25 years until they are too. This would clean the tarnish off them, since acids are very good at dissolving metals.. My results showed that strong acids such as Lemon Juice, were clearly the .
Penny cleaning science projects are a popular choice at grade school. It isn't just dirt, it is the result of the copper in the pennies interacting with oxygen in the .
STEP2 – Pour out a glass of your cola. STEP3 – Cover one side of each coin with Blu-Tac but leave the other side open. STEP4 – Pop your coins into your glass .
Science Projects on Cleaning a Penny. Ketchup. Soak your pennies in ketchup to clean them like new. Hot Sauce. Hot sauce, like Tabasco or taco sauce, also will remove the oxides off pennies. Coke. Coke and off-brand colas will quickly remove the tarnish. Citrus Juice. Pencil Eraser. Vinegar and Salt.
This graph interprets the results of the experiment. As it is easy to see, the ingredient that had the greatest impact was vinegar with salt, and the one who had the .
