If you can get test tubes and a rack, you'll probably find them easier to use than glasses. If you have to use glasses, however, that's fine. You can use plastic or glass cups; just make sure that they're clear so you're able to easily observe what's happening to the wires in them. Make sure that you have all your materials ready before you begin the experiment.
Be sure to find an area large enough to accommodate the glasses or test tubes, where they will be undisturbed for the duration of your experiment. Remember that the more clear and accurate your observations are, the better you'll be able to draw conclusions from your experiment. Use the charts on the following section, or make your own, similar charts to keep track of what you observe during the course of your experiment. Be sure to not mix up the glasses.
They'll all look very similar, so be sure that the labels remain intact and you can see them clearly. Some observations you'll want to consider are how the changes to the metal wires immersed in the distilled water compared to the wires in the salt water. Which metals had the most rust? Was the formation of the rust on any of the wires concentrated on one particular area on the wire? Or was the corrosion distributed evenly along the immersed wire? Based on your data, which metal would you recommend for the manufacture of bikes, beach chairs, and swing sets-not to mention aircraft and medical equipment?
Once you've recorded your results, you can draw a conclusion and identify the answer to the problem you stated at the beginning of your project. If you enjoyed this project and would like to take it a step or two further, you could try one of the following ideas:. Use your imagination to come up with other ways to vary the project and delve a bit further into this issue.
Just be sure to keep good, accurate notes. Students test a variety of metals in water and salt water to determine which corrodes the fastest with this hands-on printable science activity.

So What Seems to Be the Problem? Other forms of corrosion include: Tarnish found on silver teapots, trays, and jewelry Copper carbonate, or patina, the corrosion that causes copper to turn green Discolored spots that appear on brass Aluminum oxide, which forms on aluminum Chromium oxide, which forms on the outside layer of stainless steel On some metals, corrosion actually serves as a type of protection.
What's the Point? Again, the types of metal you'll be testing are: Silver Steel Zinc Copper Aluminum Your control group will be 10 pieces of wire-two each of the metals listed above. Materials You'll Need for This Project The experiment you'll be doing will require only a short amount of time to set up, but you'll need to make observations over a day period.
You will need: 12 inches Conducting Your Experiment Make sure that you have all your materials ready before you begin the experiment. Follow these steps: Wires of different materials are suspended in distilled water and salt water. Excerpted from. This book contains great information for different kinds of science fair projects.

These deficiencies can lower the strength of the part over time, and in some circumstances, become a safety issue.
There is a difference between rust and corrosion, though. Rust is generally used to describe the oxidation of iron and iron-based alloys only. Usually, rust occurs when iron-based metals come into contact with water, saltwater, acidic substances, etc. Corrosion, on the other hand, is used as a broad term to describe the destruction of metals due to chemical or electrochemical reactions.
While rust only appears on iron and iron-based alloys, corrosion can occur on almost every metal. Some metals are more resistant to corrosion than others, though. None will withstand rust or corrosion forever, but still, it should resist these reactions for the lifetime of the part. Here are those metals.
This alloy creates a thin chromium-oxide layer on the surface, which protects the part from further oxidation. Even when a crack appears in the metal part, a new layer of the compound will form, protecting the part further. Can you please help me with some resources and answers that could support my hypothesis? Again I know steel will rust faster because copper and bronze will tarnish. Steel is a refined and very useful form of the element 'iron'. Copper and bronze do not contain any iron, and only iron can rust because rust is defined as iron oxide, a compound of iron and oxygen ; so the answer is that steel will rust the fastest and copper and bronze will never ever 'rust'.
But, yes, copper and bronze do tarnish, they do corrode. But bare copper roofs last decades outdoors, and bronze statues last decades outdoors, so it is very difficult to say which of the two corrodes or tarnishes faster, but again neither rusts. Good luck. I am trying to find the answer to the same question. I am years old. And I need these answers for my science project.
I want to know what happens when copper, bronze, and steel rust? Do they break or bend easily? Can you clean it up or do you have to replace it? Also in what kind of machinery are these metals used?
Hello, Destiny. We will reword it for you to try to make it clearer. Copper is an element you can look up 'element'. Bronze is an alloy you can look up 'alloy' of the elements copper and tin. Iron is an element, and steel is a very useful, reasonably pure form of iron. Rust is iron oxide, the corrosion product of iron. You can only make iron oxide from iron and oxygen; you can't make it out of copper or tin, so copper and bronze can never rust.
Copper and bronze can corrode or tarnish, however. In fact, all metals except precious metals like gold will eventually corrode back to a form very similar to the ores we find in nature. When metals corrode the surface turns to some kind of oxide or corrosion product rather than being metal anymore -- so it no longer performs the functions of metal. Yes, it's likely to look poorly, to be weak, to bend or break more easily, to become perforated with holes.
Usually you can clean the metal -- remove the corrosion products -- but there is less metal left and eventually what's left will no longer serve the original function. Cars are made predominantly of steel, but the electrical wiring is pure copper; and there may be some wear surfaces or small electrical springs made of bronze.
I am doing a science fair project on which metals would rust the fastest. I just wanted to know which metal would only rust the fastest between iron, bronze, copper and steel. After that question is asked I would like to know what metal would tarnish the fastest between copper and steel. Hi, Dario. To keep your project moving forward, please try your best to express your question in terms of what has already been said.
I've already explained why bronze and copper cannot rust but iron and steel can. I'll be happy to explain again if you can tell me what it is that you don't quite understand.
As for whether copper or steel tarnishes fastest, get a piece of each, shine them up with fine sandpaper [affil. Best of luck! Hi I'm Owen and I'm ten years old and I'm doing a science fair project on metals that rust the fastest in water.
This site has been very helpful to me. Would you have any suggestions on how I could get hold of a some metals for my experiment? Is there anything I could use around my house? Also, do you know any good books that could help me? I was at the library and I couldn't find a thing about it?
My mum is clueless. Plain steel nails would be best, Owen. Masonry nails if you have any these are flat nails that look like long thin triangles rather than being round. Use sandpaper to remove plating or paint from whatever nails you have. If you have some painted sheet metal from an old toy or whatever, you can sand the paint off of that -- but first test it with a magnet to make sure it is steel. Pennies are copper on their surface, and electrical wire and copper piping are pure copper.
The pull tabs on soda cans are aluminum, as is aluminum foil. The main reason for librarians is to help people find what they need from a library. Ask for help there. Well, yes, Anfernee. In the same sense that fresh cod or flounder will turn into rotting fish faster than fresh cabbage or carrots will. Vegetables can rot, but they can't become rotting fish. Copper and bronze can corrode, but they can't become rust because rust is iron and oxygen.
I am also doing a science project, but mine is steel, copper, aluminum, and brass. I need help! I have looked on the internet on oxidation, but nothing comes up! Yes I am years old and I am also doing a project over what types of metal rusts faster. And I need help on finding a good Hypothesis!
I am a hard working student but I just can't find or think of a good Hypothesis it's for my science project.
