Before you can begin this project you have to find two brand new pennies. Then you have to collect either two bowls or cups that you can place a liquid and a penny into. Drop one penny into each vessel then fill one halfway with orange juice and the other with soda. After completing this portion of the experiment, place the cups or bowls on a safe surface where they will not be interrupted for a week. If there is still no rust on the pennies after a week, record what you see and let them sit for another week.
This fairly easy experiment will test what liquid will rust a wire wool. Before you can begin find five small glass bottles and wire wool. Next, label each bottle one through five so you can keep track of what liquid will go into each bottle and then put a piece of wire wool into each. Pour water into the first container and put the lid on it. Pour boiled water into the second container and put the lid on it. The third container does not need a lid or a liquid, just the piece of wire wool. Mix salt and water together in the fourth container and then put the lid on it. The fifth bottle will need a little of the baking soda with the lid on top. Once all of your containers are done, let the wire wool sit for a day in the liquid. The following day write down what you observed in each container. The jar that should show rust is the fourth jar because of the element salt.
The few materials that are needed before you can start this experiment are four plastic cups, four iron nails, salt, tap water and a jug. First, fill the jug full of room temperature tap water and then mix a teaspoon of salt into the water until it all dissolves. Place the four cups in front of you and label the first one none, 1/4 on the second, 1/2 on the third and all on the fourth cup. Next, measure the amount of saltwater you wrote for each cup and pour it into the appropriate glass. Then, add freshwater to each glass until each reaches its fullest capacity. The last step consists of placing one nail into each glass. Check on the nails the next day and see which nail has rusted the fastest.
This experiment will test how nails, aluminum foil and copper wire rust. Before you can begin this experiment find three glasses you can fill with water and salt. You must also make sure the three nails and copper wire are clean and new. Now, put the three glasses on the counter and pour one teaspoon of salt into each glass and then fill it to the top with water and mix. In the first glass place one iron nail. The second cup, which will be designated as the control cup, will consist of an iron nail that has aluminum foil twisted around the entire nail. The last glass will have copper twisted around the iron nail. Watch what happens in each cup and see which one rusts fastest.
