The problems with mold and mildue wile camping HISTORY & PROBLEM STATEMENT JUSTIFICATION SOLUTION CRITERIA & PARAMETERS SOLUTION DESIGN SOLUTION DESIGN MATRIX TESTING A clear, concise statement of the problem you are trying to solve, along with a brief background/history of the problem. Any supporting evidence you have gathered that justifies your problem statement. Make clear, obvious connections between the evidence and how it provides specific justification. You must cite all sources of justification. Brief summary of existing solutions and their drawbacks, followed by the actual report (nothing is wasted in EDD!) Remember to provide a link between the cons you found and your solution A bulleted list of all the things your solution should be able to accomplish (criteria), along with actual measures by which they will be evaluated (parameters). A detailed verbal description of your proposed solution and how it works. You should include sketches, inventor drawings, models or other supporting documentation to help explain your design. An explanation of why you chose your solution is also helpful. A matrix that compares existing solutions with your proposed solution (why is yours better?). EXISTING SOLUTIONS REPORT & SUMMARY Based on what you know now, how do you propose to test your solution? (it would be a good idea to look at criteria and parameters to help flesh this out). hi my name is megan Fiberglass Fiberglass Woven fiberglass coated with PTFE (Teflon or silicone) is also a widely used base material. Glass fibers are drawn into continuous filaments, which are then bundled into yarns. The yarns are woven to form a substrate. The fiberglass carries a high ultimate tensile strength, behaves elastically, and does not suffer from significant stress relaxation or creep. The PTFE coating is chemically inert, can withstand temperatures from 100°F upwards to 450°F+. It is also immune to radiation and can be cleaned with water.

Because of its energy efficiency, high melting temperature and lack of creep, fiberglass-based fabrics have been the material of choice for stadium domes and other permanent structures, particularly in the United States. However, when properly constructed, polyester structures may be equally durable. // Can withstand temperatures from 100°F upwards to 450°F+ Silica gel's high surface area (around 800 m²/g) allows it to absorb water readily,

making it useful as a desiccant (drying agent).

Once saturated with water, the gel can be regenerated by heating it to 120 °C (250 °F) for two hours.

Some types of silica gel will "pop" when exposed to enough water. Silica Gel Properties Waterproof Fabric Waterproof/breathable fabrics resist liquid water passing through, but allow water vapour to pass through.
Their ability to block out rain and snow while allowing vapour from sweat to evaporate leads to their use in rainwear, waterproof outdoor sports clothing, tents, and other applications. introduction

List of Associations that can be contacted. Intro Problem Statement
Camping gear getting wet can cause mold to grow, thus ruining your gear. camping gear needs to be cept dry.
because wet gear can cause rust, mold, and mildeew to form A typical problem statement addresses four W questions and two H questions.

Who - is affected?
Campers, hikers, and backpackers

What - is the effect?
Ruining your gear
Some mold can be harmful to your health. It can trigger some allergies and asthma symptoms in sensitive individuals.

When - does the effect manifest itself?
Within 24 to 48 hours of an object being wet.

Where - does the effect take place?
On a damp surface

How much/many - is the frequency/amount of the effect?
?

How - is the effect manifested?
They reproduce by spores - tiny, lightweight “seeds”- that travel through the air. Molds digest organic material, eventually destroying the material they grow on, and then spread to destroy adjacent organic material.
Problem Statment The End Justification Existing Solutins (matrix) when camping it is comenly known that you dont want to get your gear wet.
There are multiple resonse to keep your gear dry on a campout:
rust
mold
milduew
staying dry so you can stay worm Objective: Camping gear getting wet can cause mold and mildew to grow on your camping gear, thus ruining your gear.

Method: mold and mildew ruin camping gear.

Original problem statement: “Mold and mildew ruin camping gear.”

Contributing Factors:
Morning dew produces moister on gear
Rain will cause your gear to get wet
Putting gear away when it’s still wet
If the gear is dirty and then gets damp
Not washing your gear after a camping trip
Not allowing gear to dry completely
If not moister is not removed, spores form "Violinists develop dermal abrasions, visible to the unaided eye, on the underside of their jaw on every occasion when continuously playing for greater than 58 minutes".

[WHO Violinists][WHAT develop dermal abrasions,] [HOW visible to the unaided eye,] [WHERE on the underside of their jaw] [HOW MUCH/MANY on every occasion] [WHEN when continuously playing for greater than 58 minutes.]

and then zeroed in to focused on the preventing of mold and mildew from forming The reson i wanted to focus on the prevention of mold and mildew is because mold is not only ruens camping gear but it also is a health risk. ok so i just got a great idea

i found a bunch of sorces and justifications
i now have at least 3 justifications:
why focuse on mold and mildew
proof that mold grows on tents and nilon, and that its a problem
and that is grows on clothing on campouts that is a prblem Great strength with light weight
sturdy, solid, came with great customizable foam
Waterproof hard case
Great for its purposes - water tight rigid case to protect gear. 
Plenty of room, safe for equipment, durable
Very rugged, good organizer 
not too large, not too small 
durable, waterproof 
Sturdy, no-nonsense styling 

Bulky but with a reason
pricy, heavy
a little expensive  
Don't leave plastic hard case in car on a hot days (90+ degrees)
a little larger than expected. Definitely not a carry-on
Stiff latches can be hard to close 
latches are stiff 
Cost, clamps are a little hard to open and close
Case tips over when lid is opened  Pros Cons Justifications

1.Mold and mildew does and can form on camping gear and is a problem when camping.
“Mildew is the ugly by-product of a fungus that grows in warm, wet areas. Because camping is an outdoor activity, mildew and mold can grow on camping equipment despite the best efforts to keep the equipment dry and mildew-free. Once the mildew is gone, getting rid of the smell can take more work. When mildew rears its head, try these steps to kill the mildew and remove the smell.”

2.Camping gear (such as a sleeping bag) getting wet can cause mold to grow.
“A wet or damp sleeping bag is a breeding ground for mold. Even storing it in a cool damp place can cause mold growth. Simple washing won't get rid of the mold spores.”

3.Mold can penetrate waterproof fabric such as a tent and ruin gear.
“Mold is a fungal growth that reproduces by spreading spores. When it grows on fabric, it is referred to as mildew. Mold grows in a dark, warm and damp environment. It can penetrate the waterproof coating on tent canvas and destroy the fabric below. In addition to damaging the tent, mold spores cause problems for people with mold allergies. Mold has also been linked to asthma, chronic sinusitis and a weakened immune system.”

4.Mold forming on camping gear is a problem among campers.
“One of the most common problems that I see with tents is that some people will not properly dry their tent out after a camping trip where it has rained. Even when it doesn’t rain, moisture can seep up through the ground leaving the bottom of your tent damp. Storing a tent that is damp or wet will cause mold to set in and eat away at your tents fabric.”

5.Mold can cause health problems.
“When molds are present in large numbers, they may cause allergic symptoms similar to those caused by plant pollen. Exposure to a large number of mold spores may cause allergic symptoms such as watery eyes, runny nose, sneezing, itching, coughing, wheezing, difficulty breathing, headache, and fatigue. Repeated exposure to mold can increase a person’s sensitivity, causing more severe allergic reactions.”

Topic Area or Problem Statement:
Camping gear getting wet can cause mold and mildew to grow on your camping gear, thus ruining your gear.

Brief summary of discussion:
We talked about how I changed from my original problem of animals getting to food while camping to the problem of mold growing on camping gear.
We discussed what I had found on the problem and what I could do to find more, like having to ask professionals for their advice. Mr. McGee gave me a few suggestions on what to do.

Suggested course of action:
I needed to refine my problem statement.
Define mold and mildew.
Explaining what causes it to grow and what it needs to grow.
Answering the “4W & 2H”
Who, What, When, Where, How much/many, How
And get my work turned in
