Week 8 Lab + Week 9 Lab Prep

Objective: Dry-run presentation of final Freshmen Design Presentation

Date: May 22, 2014

Today in lab:

• Present PPT prepared for the dry run
• Get feedback from Dr. Allen and the Teaching Fellows
• Design Matrix is unecessary; just the summary will keep the section simple and concise
• Don't rush through the presentation
• NEVER discredit ourselves by saying "Because we're only freshmen and have insufficient knowledge..."
• Further explain design a little (why that formation and number of donuts? etc)
• Don't be nervous

For next time:

• Memorial Day holiday!!! (Mon 5/26)
• Remaining groups - not us - will finish dry-run presentations
• Prepare for final presentation
• Practice individual presentation slides! :)

Week 8 Lab Prep

Objective: Prepare for this week's preliminary presentation

Date: May 19, 2014

Today's Discussion:

• Week 8 Team Assessment
• Presentation prep
• Add decision matrix
• Other solutions
• Add block diagram
• Experimental results + analysis
• Design model (Creo)

Figure 1: Completed Model of Product 

Figure 2: Really cool mess-up of the model

• Experiment materials
• Make prototype
• Get take-out cup from Hans
• Motor oil
• Camcorder

For next time:

• Finish prelim PPT by Wednesday 9pm
• Continue preparing for experiment

Week 7 Lab

Objective:


Date: May 15, 2014


Today in lab:

• Check progress with Dr. Allen
• Stuff to research
• Sponge absorbance vs Design absorbance
• Will our product suffice when another Gulf of Mexico incident happens?
• Currently popular oil spill solutions?
• Overall shape of donuts connections - how big? Star formation? Line formation?
• Costs of competitors, approximate price per unit

For next time:

• Start on preliminary PPT presentation for next lab
• Bring in sketch and 3D model of product (donuts!)
• Group consultation appointment with Engineering Librarian on Tue May 20th 3pm-3:20pm

Week 7 Lab prep

Objective: Discuss and analyze results of last lab's experiment, work on draft of Final Report due by lab this week

Date: May 12, 2014

Today's meeting:

• Chi-Square Goodness of Fit test, testing

• Ho: percent change in sample mass is approximately equal to the expected values
• Ha: at least one of the observed percent change in sample mass differs from the expected value
• Use significance level 5% (alpha = 0.05)
• Results:
• From the experiment, there is sufficient evidence to support the claim that hair absorbs 2x its mass in water, 10x its mass in an oil-water mixture, and 12x its mass in oil!!!
• Q's for Dr. Allen (to ask on Thursday)
  - Is appropriate for the presentation to incorporate a little humor (especially puns)?
       --> This problem just got hairy!
       --> It's about to get mesh-y!
       --> So... wat'er we waiting for??
  - Is it possible to get a projector, so we won't need to prepare a larger scale demo?
  
  

For next time:

• Finish individual report parts by Tuesday night
• Finish editing and submit on Wednesday
• Bring laptops to create PowerPoint for week 10's final presentation

Week 6 Lab

Objective: Continue making progress with lab

In lab:

• Make block diagram of project
• Check progress with Dr. Allen
• Begin experiment!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
• Lab coat and goggles preparation
• Set up scale
• Prepare the five mixtures for experiment

 Warning! This is about to get hairy!!!!!!!!!!

For next time

• Lab space open Friday (tomorrow) 3-5pm
• Will continue and finish hair absorbency test

Week 6 Lab prep

Objective: Confirm materials for lab, finalize lab procedures, split up final report parts, and continue research

Date: May 5, 2014 (Cinco de Mayo!!!)

Today's Discussion

• Lab materials all set, but only have one hair type
• Will test absorbency in various solutions instead of absorbency of various hair types
• Research for Thursday
• Overall structures of mat
• Regions and placement of polar and non-polar materials
• Possible materials that could be incorporated (i.e. nanotubes)
• Split up final report parts, details sent in email to group

For Thursday:

• Bring in individual research and some sort of visual (diagram, 3D model, etc) 
• Present to the group (in the second hour of our lab time)
• Vote on whether each proposed idea is feasible for the not-so-distant future and whether we want to include it in our final presentation ppt

Week 5 Lab

Objective: Continue to make progress in project

Date: May 1, 2014

Today in lab:

• Group updates with individual parts
• Check up with Dr. Allen (see notes and images)

Notes:

Notes 1: Materials and hair sample measurements

Notes 2: Solutions for next week's experiment

Notes 3: From discussion with Dr. Allen

Images:

Image 1: Scale for measuring mass of nets and hair samples

Image 2: Net with ruler

Image 3 and 4 (from left to right): net stretch out with ruler, motor oil in container

For next time:

• Prepare last of lab materials
• Prepare to finalize lab procedures and data collection/ analysis methods
