Rust is a broad topic of discussion for science classrooms at all grade levels. While elementary teachers present rusted metal as a simple example of a chemical reaction, high school instructors point to rust in explanations of oxidation and reduction reactions. Students in public school or home school are able to perform experiments on rusting iron nails for class research assignments or science fair projects.
Hypothesize whether cold or warm air temperatures will affect the rate at which rust forms on iron nails.Gather nine iron nails and three beakers or glass containers of the same size. Place three nails into a container filled with tap water. Place three nails in a container and fill with ice cubes. Place the remaining nails in a container filled with tap water and place under a heat lamp. Leave all three containers uncovered in an undisturbed area and observe daily for one week. Ice must be added to the second container frequently to maintain a cold environment throughout the experiment. Oxygen, the primary component of rust formation, combines with other elements, including iron, more readily at warmer temperatures, so the nail under the heat lamp should rust first, while the nail in ice should be the last to form rust on its surface.

Density experiments are versatile to fit most age levels. Students should hypothesize how the oxidation reaction that produces rust on iron nails affects the density of the nails. Purchase 2 pounds of iron nails and separate into 1 pound groups. Ensure the mass and volume of each group is equivalent. Leave one group indoors so rust will not form on them. Allow the second group to rust naturally outside, or accelerate the rust formation using a technique from the previous experiments. When oxidation is complete, calculate the mass and volume of the second group to determine whether any change in density occurs during oxidation. Rust is less dense than iron, but a gram of iron will yield more than 1 gram of rust, so students should observe a weight gain, and therefore an increase in density, in the rusted set of nails.
If you ever wonder why nails rust, it's because rusting happens when a metal is exposed to oxygen. The "rust" is actually iron oxide and forms when the iron in the nail reacts with the oxygen in the air or in liquids. The molecules of iron on the surface of the nail exchange atoms with the oxygen in the air and produce a new substance, the reddish-brown ferrous oxide, a.k.a. rust. A simple science project tests the effects of different liquids on the rusting process, such as oil, water, vinegar and detergent.
Place numbered test tubes or cups in a line to let you compare the effects of different liquids on your nails. Before you begin your experiment, take a photograph of each nail. You may also weigh each nail at this point. Place one nail in each test tube or cup.
Q. I did a science fair project on the effects of rusting nails. I used tap water, salt water, Sprite, and vinegar. after 14 days the tap water had rusted the nail entirely within 10 days. The salt water rusted the nail entirely within 12 days. both the Sprite and vinegar did not cause any rusting on the nail. Also the tap water was first to sprout signs of rusting within 3 hours of the submerging of the nail. Why did the tap water work most effectively?
You have probably seen action movies or science fiction movies where acids dissolve metals. But most acid used in the metal industry is actually used to remove rust from metal rather than to dissolve metal. If you put a rusty piece of metal into a strong acid, the rust will disappear almost instantly but it will take quite a long time for the metal to dissolve. So acids are actually used primarily to remove rust not to make rust.
A. In response to your question on nails rusting, I am in yr 8 as well and I am doing the same research... but I am doing an experiment, out of the six containers, tap water, vinegar, metholated spirits, bicarbonate of soda in water, lemonade, and salt water, the tap water over 1 night has significantly rusted the nail. then the salt water. the vinegar has completely cleared the nail of any existing rust, putting all the remaining rust on the top of the nail, which is above the water, the lemonade has corroded the nail above the surface again, the bicarb hasn't done anything and the "metho" hasn't done anything but smell disgusting. it would be a good idea to check these results by doing the experiment yourself, but remember to leave some nail over the water line, and don't use coated nails, because they are designed NOT to rust, so nothing will happen. ta,
A. I am in the seventh grade and we had a science fair so I decided to do it on ways to cause rust I used:1. 5 plastic cups or containers2. 5 nails make sure the steel and can rust3. 1 cup bleach 1 cup vinegar 1 cup water 1 cup salt water and 1 cup sugar water in both of the sugar and salt water I used 2 tsp of each sugar and salt4. and 2 days to do thisI put the nails in each cup and let them sit 4 a half an hour the one that had the most affect was the one with the bleach and the tap water. In the end the best way to cause rust is to use Clorox bleach.
Q. Umm I'm in 8th grade and I had to do a science fair project. my project was too see what liquid rusted a nail the most...I used vinegar, lemon juice, and tap water...tap water does rust it the most....which is kinda odd cuz its not very acidic. and vinegar rusted only the top of the nail in huge chunks..(it was gross)I think you should use non galvanized nails and non galvanized steel bits but its kind of hard to real steel. you could just get it from a hardware store or ask your parents to take you to a like car fixing place and maybe ask them if they have and unused bits of steel that hasn't been coated with anything to protect from rust.
But what you might think about is . . . the point of this effort. I mean suppose you find that Kosher salt rusts steel wool faster or slower than water softener salt -- so what? The reason I ask is not to pooh-pooh the project, of course, but in hopes that you will think about what you are supposed to get from this effort that is valuable.Here's what I mean. Suppose you have two piles of match sticks with 301 in one pile and 203 in the other. One way to know the total number of match sticks is to memorize a table of every possible 3-digit number added to every other possible 3-digit number -- but to do it that way you would need to memorize one million combinations. But I was able to do this addition in my head, and I think you were too, because we learned useful, flexible concepts in arithmetic class like adding the digits column, then the tens column, then the hundreds column. You should be trying to learn similar important concepts from your science experiments, not just a million individual one-at-a-time facts like whether kosher salt rusts steel wool faster or slower than water softener. So the real question is what are the concepts that you think you are learning from this project :-)
We have an FAQ: What Liquid Cleans Pennies Best; although that question is a little different than what liquid rusts nails best, I think you will find it interesting and helpful for your project because it explains the purpose of these experiments and a standard way to approach them. Good luck.
Q. I just did an experiment on rusting nails and did salt water and then distilled water. The distilled water rusted the fastest and took off the metal in sheets. Why did the distilled water rust the nail so fast versus the salt water? I would have thought the opposite!
Okay where the hell do I get research for this? I'm doing a science fair project on which substance rust nails the fastest and I can't find anything. I don't know where to get the stupid info! ugh! I HATE science fair! This is my second year doing this and I hate just as much! And my 8th grade science teacher is on my back about this because I'm supposedly her "best student" and she expects me to win the freaking contest! WHAT THE#^%#%$^&*!
This project can be done by a variety of different ages. Younger students can experiment with making steel wool pads rust and trying to find substances that might prevent rusting. High school students can appreciate the chemistry involved.
Today's lunch was inspired by the science experiment my son recently completed for a school project. He decided to investigate which liquid(s) would make a nail rust the fastest. To complete the experiment he gathered five clear plastic cups, placed a nail in each cup, and filled each one with a different liquid (vegetable oil, vinegar, orange juice, 7-up, and salt water). After letting the nails soak in the liquids for several hours he began to notice that only one of the nails was rusting. We left the cups sitting on the counter overnight and in the morning there was still only one nail that had any signs of rust on it. Can you guess which liquid it was? Here's a hint:
Your body depends on a wide range of potentially toxic minerals to survive. One is iron. If taken in its pure form, iron would kill you, but the Creator God put in place an elegant system to supply your daily iron without adding rusty nails to your breakfast.
Nails are fasteners that attach objects to one another. While important in the construction of buildings and appliances, nails are also used in art projects or science experiments. Rusting is an electrochemical process in which two compounds combine to form a new compound. In most cases water molecules combine with iron molecules to create rust. Nails are made from a variety of metals including iron, tin and steel, so when the nails come into contact with water they rust easily.
In my district, summer school is all enrichment based. I designed a 3-week course using Titanic lessons, where we would do daily science experiments, literacy connections, and more. I LOVED teaching this class just about as much as I loved learning about the Titanic. I stopped teaching summer school when I had my girls, and unfortunately, I never took any pictures of the class back then. I made it my mission this year to pull out my bins of Titanic lessons and materials to take pictures of some of the activities and experiments that we loved so much. And here they are! So many Titanic activities for you to do in your classroom. Have fun and always, always, always Remember the Titanic! 2ff7e9595c
