Give instructor top 3 project choice list
I was assigned Corn Starch after problems with the internet prevented me from sending in choices.

Write problem statement
Make the corn starch oobleck, put it on a speaker make it dance.

Assign Task1
Task one was not decided on, I was supposed to meet with a group member on Friday, but due to a miscommunication and a last minute appointment, I was unable to. So the project was stalled for the weekend.

Compare actual work done to Task2
As no real work was done on the first week, the differences where no work was done over the weekend was minimal.

Week1 Narrative
Week one was about getting the speakers to work. getting the speakers to work was really the first step to this project, the speakers had to work to get the waves in the fluid and the monsters to form. We brainstormed and tried to wire the headphone jack to one of the speakers to see if it would work. I noticed that the speaker had a wire on the inside was disconnected and wouldn't work. We then tried a few other speakers, wiring the speakers to the jack to the computer to test to see if they were working. They didn't work. On Wednesday in class we tried again, and were repeating our mistakes since we are all pretty new at wiring speakers, when Professor Forester told us about the wave generator and the wire to it and voila! The speakers worked. I then played around with the wave generator box to find the proper waves and frequencies needed to create low sounds with plenty of vibrations. Sine waves and 10Mhz work really well.

Week1 Peer Review
Go to each team mates weekly summary wiki page. Read their activities and narrative. Then go the associated discussion page. Say something positive on this page. Try some constructive criticism.

Assign Task2
Create a test of the corn starch oobleck and be prepared to recreate it in class on Monday.

Compare actual work done to Task2
Rationalize differences

Week2 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.

Task two was to create ferro fluid out of printer ink and vegetable oil.

Week3 Narrative
I got the ink cartridge that the employee at Office Depot said contained Micr (the magnetic ink needed to create ferro fluid) but after some trial and error, the ferro fluid didn't form. After doing further research on the ink, I found out that it didn't contain any Micr after all. I then decided to order toner from the internet and it should arrive by Monday.

Assign Task4
I will run some calculations to see how much it would cost per volume to create a corn starch solution for the Engineering event in the spring.

Compare actual work done to Task2
In this week I didn't get to do the equation, but I made a successful ferro fluid batch.

Week4 Narrative
After waiting for the correct MICR toner to arrive, I was able to successful create ferro fluid, although to a lesser degree than some of the videos online. My ferro fluid reacted, which was an improvement over the previous week, but only formed small blobs and not spikes like the videos showed. I believe this was due to the ratio of iron to ink in the MICR powder, the size of the magnets used to react the solution, and the ratio of vegetable oil to MICR toner.
 * My experiment with ferro fluid.

Week4 Peer Review
Commented on Bamminnick's page and will check back in with Alex's page to see if he has added anything.

Will be working on the perfume project now, created most of the pages for Perfume, with help from Baminnick. Will begin distilling next week.
