The research plan must include the following:

I. Statement of the Problem/s:
This study aims to
Specifically answer these questions:
1. What chemicals or substances would be effective to use?
2. Where else can we apply the monolayer, other than plastic, using the same procedures? 3. How long will this effect last?
4. What liquids can it repel besides water?

II. Hypothesis:

a. There is a significant difference in the results using varied amounts of concentration of chemicals. b. There is no significant difference in the results using varied amounts of concentration of chemicals. III. Methods/Procedure (Describe in Detail)

1. Procedure
The materials for this experiment are: gloves, cans of compressed air, ethanol, a bottle of water, forceps, sand paper, a solution of aqueous Silver Nitrate, copper pieces, 11-mercaptoundecan-1-ol (MUO) solution, and pieces of plastic mold. First, we will boil the copper pieces to at least 4 degrees Fahrenheit (1083.0 degrees Celsius) for it to melt and while it’s not dry yet, we are going to soak the pieces of plastic mold so that the copper would stick to it as a thin layer of coating. We will then let it dry. After letting it dry, we will place it on a fresh paper towel. Using a piece of sandpaper, sand both sides of the copper-coated plastic until each surface is shiny. Then we will pick up the sanded copper-coated plastic using the forceps and rinse both sides with ethanol for 5 seconds, followed by water for 5 seconds. After that, we will place the cleaned copper-coated plastic in silver nitrate solution and swirl the solution containing the piece of plastic for 25 seconds, then remove the plastic using the forceps and rinse both sides with water for 5 seconds. After that, we will dry both sides of copper-coated plastic with compressed air. We will then soak the copper-coated plastic in the 11-mercaptoundecan-1-ol (MUO) solution for at least 10 minutes. After at...
