Rusty Nails

Data: let the nails be in the chemical formula for 6 hours. After each hour has passed, record the amount of rust on the nail. If there is none, put no change, if there are microscopic fragments of rust, put very minor change. If there is only a few spots with rust, put minor rust, if there is average/little rust, put medium. If there is rust on most of it put mostly rust. If there is rust on all of it, put rusted. Hour 1: Nail A: No rust Nail B: no rust Hour 2: Nail A: no rust Nail B: no rust Hour 3: Nail A: slight rust Nail B: no rust Hour 4:Nail A: medium rust Nail B: very Slight rust Hour 5: Nail A: medium rust Nail B: Slight rust Hour 6: Nail A: Fully rusted Nail B: Slight rust

Hypothesis: It is proven that Brand B nails are the better buy and are more durable than brand A nails by using a chemical formula.

Background Information: Project on which nail is better to buy. Seeing which brand nail has less rust after an experiment. The nail with less rust is the better buy for people/builders. This is great for many people because many people want to buy the best quality product. I researched many websites on google scholar to help me come to the conclusion on this project. i also came to Mr. Paczynski and he said that this experiment would be a great project for STEM.

Question: Which brand of nails are better for builders to buy by seeing which nail has less rust after an experiment.

Materials: 1. Two Cups 2. Two Different Brands of Nails 3. Salt 4. Vinegar 5. baking soda 6. lemon lime soda 7. Bleach 8. Hydrogen peroxide

Procedure:

Get two cuts and put all materials in there. Put the brand A nail in one cup and put the brand B nail in the other cup. Set a timer for 6 hours and wait till the timer is done. Make sure you check on the nails each hour. After 6 hours check both nails and the one with less rust or no rust is the better buy for builders. Builders are looking in which nail to buy, brand A or brand B, This is meant to help construction workers decide which nails are better to use and more durable to help them build.

Abstract:

Construction workers and builders uses nails all the time. Most builders wonder which nails to buy, they need nails that will last long. They need to decide which brand of nails to buy. While testing this experiment, scientists decided to use different materials to rust nails and see which brand nail is stronger and has less rust. The nail that has less rust is the better buy for builders. Using simple ingredients like vinegar, salt, baking soda, and some others, we can rust nails. The dependent variable is the mixture of salt, vinegar, baking soda, sprite, bleach, and hydrogen peroxide. The independent variable is the nail being tested in the mixture that is used to see which nail has less rust.This project looks at which brand nail rusts less in a certain amount of time. Both nails are put in the same formula and the result is that the brand B nail rusted less in six hours than brand A nail did. With this experiment, builders can conclude that brand B nails are more durable and better than brand A nails and they should use brand B over brand A.

Conclusion: When you mix salt, vinegar, baking soda, bleach, hydrogen peroxide, and lemon lime soda, it creates a chemical reaction to make metal rust. We have two different brands of nails and when you mix all the chemicals together in two different cups, then you place the nails in and wait for 6 hours. After the six hours, the brand nail that has less rust on it, is the better buy for builders and people. This experiment is to see which brand nail is the better buy for people. By a scientific experiment it is proven that brand B nails and better than brand A nails. After this experiment the conclusion was that brand B nails are more durable and the better buy for people.

Future Directions: In the future we will know how to create a chemical formula to make rust. This will give you more knowledge and would help you in the future.
