Give instructor top 3 project choice list
My top 3 projects I selected are model boat, bridges, and static electricity. I ended up in the model boat team.

Write problem statement
The goal of this project is to build a model boat that can move by remote control. So I decided to look for a radio control car and take it apart and learn how the car move by remote control. Then I will use that part from inside of the rc car that receives radio waves from remote control and then put it for the boat I am going to make. I want that rc car part for the boat to function. It's the function part. Also I will think of a design of the boat. I don't want the boat to have too much mass or else the boat won't move freely. I want to keep the boat lighter mass as possible. So I am thinking about plastic soda bottles.

Assign Task1
So the assignment for task one is to learn how the radio control car functions by the remote control.

Compare actual work done to Task1
Right now I am planning of a design of what the model boat should look like.

Week1 Narrative
I want to use soda plastic bottles for the structure of the boat because they contain lighter mass to support the boat. We don't want to make it heavier or else the boat wont move properly.

Assign Task2
I will continue and figuring out the perfect design of the model boat I where should I put the RC reveiver part piece from RC car.

Compare actual work done to Task2
I will look for objects of building a model boat.

Week2 Narrative
A week ago I bought a 2-liter bottle of Pepsi. I emptied it by drinking the whole bottle. I will use the empty Pespsi bottle for the base of the model boat. Then I took the RC car apart and found a green circuit board where it receives signal waves from the remote control of the car. The goal is to figure out where to put that circuit board on the empty soda bottle. Looks like I need another 2-liter empty soda bottle to complete the base of the boat. I want to put the circuit board between the bottles.

Assign Task3
I will get another empty 2 liter bottle and enrich the boat's design.

Compare actual work done to Task3
I will design the model boat by using the following materials.

a. 2 2-Liter plastic soda bottles

b. 3 rectangular balsa wood pieces with lengths 23cm and widths 7.8cm.

c. PC fan

d. 9-Volt battery

Week3 Narrative
First, I super glued the 2 big plastic bottles together and let them stand vertically for them to dry. The reason I let them stand vertically is to make it look perfect. I waited for two hours for the glue to dry. Then I cut 3 balsa wood rectangular pieces. Each has a lengh of 23cm and width 7.8cm. Then I super glued them on one side of the soda bottles to create the base of the boat. I let them dry overnight. Next step is to get the PC fan working. In order to charge the PC fan, I need a 9-volt battery. I saw this youtube video,where this person charged the PC fan with 9-volt battery to get the boat to move.So the following day, I went to the dollar store and purchased some 9-volt batteries. I attached the PC fan wires to the 9-volt battery and it worked! Right now, the goal is to place the PC fan connected to the 9-volt battery on the model boat. On a Friday night, I super glued the PC fan boat on the back of the model boat and I waited for a couple of hours for the glue to dry. On Saturday morning, I filled a large container with water. There was a problem. The boat sank backwards vertically. So I got a help from my brother to hold the center of the boat. While he holded the boat, I attached the PC wires to the battery. The good news is that the boat moves but the bad news is that the boat moved backward!. So that's another problem. So there are two problems so far. One, the boat sank backwards vertically because it did no achieve equilibrium. That means there's more mass on the back of the model boat then the front or the middle. In order for the boat to reach perfect equilibrium, I should do center mass. So I took off the PC fan and super glued again in the middle of the boat to achieve the center mass. Another problem is that the boat moved backwards because the air is blowing toward the front side of the boat. In order for the boat to move forward, I need to turn the PC fan backwards for the air to go in the opposite direction. If the air of the PC fan goes backwards, that means the boat moves forward where I wanted. The link to the boat http://www.youtube.com/watch?v=WKBHfgjVzjs

Rationalize differences

Week4 Narrative
Upload photos to wikimedia. Upload video to youtube. Convert all spreadsheets, documents, and presentations to wiki format and create wiki subpage of your page for each of them. Link to them here in a narrative that tells a story. High light the problems (engineering problems) you had and how you solved them.
