◦ Emmanuel (Emma), from Uganda, weighed 9 lbs at
the age of 2 ½.
◦ He was malnourished. Could not walk or smile,
had no hair was literally just bones.
◦ 9 million people die of hunger and hunger-related
diseases every year.
◦ Emma would have been one of those people
had it not been for FMSC.
◦ 300 million children go hungry every day.
The Project’s Foundation
◦ Mission: Feeding God’s starving children hungry in body and spirit.
◦ Vision: Feed My Starving Children strives to eliminate starvation in
children throughout the world by helping to instill compassion in
people so that they may help those in need.
◦ Goals: During the 2 hours allotted per session, volunteers pack
bags of food and seal boxes of these meals.
◦ In such a short amount of time, as much as 38,232 meals can be packaged;
feeding 107 kids for a whole year!
◦ Woman found the children abandoned by
their drunken father and helped them get in
contact with FMSC.
◦ 11 year old Brian cooks the MannaPack for his
◦ More than 70 countries through missionary
partnerships at orphanages, schools, clinics,
refugee camps and malnourishment centers.
◦ Barbados, Guatemala, Philippines, Thailand,
◦ Volunteers hand-pack meals for malnourished children, and then the
meals are sent to partners in various countries to help break the cycle
• One year later, Emma now weighs 22 lbs.
• He can walk, smile, and talk.
• With FMSC, you can directly see the impact
• More on his story:
◦ 92% of total annual donations spent directly on feeding.
(This includes volunteer labor.)
◦ 99.6% of meals safely reaching intended locations.
◦ FMSC food has reached more than 70 countries.
◦ 22 cents is the current meal price. (4th straight year with no increase.)
◦ 48% average year over year growth since 2003.

To design and fabricate a solid-propellant rocket to accurately land on a target located between two
A removable payload must account for at least 20% of
the rocket’s total weight
The launch rail must be set within 30 degrees from
The solid-propellant motor impulse must not exceed 20
The rocket must be launched 10-15 times, in order to find
the average distance from target.
A model of the computer simulation and its subsequent
analysis of the dynamics of the rocket flight must be
created, documented, and reviewed prior to a team
proceeding with field tests.
The sum total of the cost of the operation of this project,
design, and fabrication should be less than $250.
The rocket fabrication must not contain metal parts.
The rocket must be fabricated by the team, and not store
The team has three weeks after the preliminary design to
complete the model

Evaluation and Optimization
The prototype was fabricated and tested more than 3 times for each series of trials.
- Trial series 1: A8 motor with 20% payload
- Trial series 2: B6 motor with payload of 40% (in effort to increase % payload)
Results (Streamlined operation) :
- Using the A8 motor with 20% payload presented the most accurate flight.
- 60 degrees for the launch angle also results in the least amount of error
- Drag coefficient of 0.0015
- Our rocket empennages loosened due to lack of curing.
- Our payload separated from the rocket due to insecurity of nose cone and the increase in pressure.
- We let the epoxy cure for more than 24 hours before launching.
- We added tape around the nose cone to ensure it is tight enough to remain secure.

The vast majority of Americans do not meet minimum RDA standards of vitamins and minerals
93% of vitamins D and E miss recommendations from diet
61% not enough magnesium
50% not enough Vitamin A and Calcium

Supplements offer an unregulated promise of health in a bottle
It is BIG BUSINESS, with BIG PROFITS
Can a healthful diet provide adequate protection? Or, are supplements the answer?
• Choose a supplement
• Choose a side, for (PRO) or against (CON)
• Research, using evidence based, peer reviewed journal sources, or scientific
websites provided by the instructor
• Build your argument for or against supplementation based on scientific
evidence, not your or someone else’s opinion

Vitamin D is a hormone responsible for bone health and development
It also has some effects on other body systems, such as immune, endocrine, and
It is made in the body from a conversion that happens in the presence of adequate
daytime sun exposure at certain latitudes, certain times of the year
Vitamin D: Conditions Recommended
• Post menopausal bone loss
• Type II Diabetes
• Preventive: colorectal and breast cancers (observational studies)
Vitamin D: Groups Affected; recommendations
Breast fed infants
Older adults with “marked Vitamin D deficiency”
may improve balance and muscle strength, but not gail
Girls age 9-18
People taking statins (high cholesterol medications)
Taking daily high doses (over 800 iu) without physician guidance
Adverse effects are shown with higher doses of Vitamin D
May actually weaken muscles
Benefits appear to happen only for those with markedly lower levels at testing
lower dose (800 mg-1500 mg seems optimal)
Harm (or no benefit) may happen at higher doses
Consult physician for optimal dose level
Blood testing to determine deficiency
Not advisable to take in the absence of deficient signs (which means testing levels
below 20 ng/mL
More is NOT better
Most research is quite mixed, and does not account for confounding or other
factors which distort research
It is not the magic pill

• What it is
• What it does/regulates sleep wake cycles
• Produced from the Amino Acid tryptophan
• Possibly beneficial in supplement form; not proven
• Melatonin in depth
The Bottom Line
• Many studies have been conducted on Melatonin’s use as a sleep aid
• Research is mixed
• Short term safety is established
• No studies on long term safety
• Side effects include drowsiness next day; possible behavioral disturbances;
drowsiness, dizziness, headache, nausea
• Do not use for long term; safety not established
• Practice sleep hygiene
• If you have a sleep problem, see your physician. Sleep problems can be
symptom of underlying health problem
Collagen Peptide Powder
• Derived from Cow bone or Pig skin
• What is Collagen?
• Is mixed. There is no scientific evidence that collagen works any better than
placebo for the myriad of conditions that it is purported to treat.
• All collagen supplements are animal derived. There is no organic form of
collagen on the market
• Collagen can cause digestive distress; weight gain; susceptible to heavy
metal toxicity, contamination.
• Non research based
• Collagen production declines with aging (like all things), and a supplement
or pill can’t make that go away.
• Save your money $$$ eat healthy and exercise throughout life; wear
sunscreen to protect your skin
• A plant that is used in Ayurvedic medicine and cooking
• Dried, powdered roots (rhizomes) used medicinally
• Bioactive compound: curcuminoids/the compound curcumin
distinctive yellow color
• Thought to have anti-inflammatory and anti-oxidant properties
Does it work?
• Scientific studies (with mice) show promise; but no studies in humans show
any benefit for the treatment or prevention of cancer
• Phase I and Phase II clinical trials on humans are currently underway
• Shows some benefit due to anti inflammatory properties
• May interfere with other medications
• It is not really known if it works for what it is purported to treat
• Dosages in turmeric form (the herb, not the bioactive compound) are not of
high enough concentration of curcumin to have any benefit
• Probiotics are a booming business with many promises made
• Live organisms, when administered in volume, benefit the host
• Probiotic foods (kefir, yogurt) and supplements
• Must be taken indefinitely since no permanent alterations of the gut flora
after consumption is possible

Mechanisms of Action
• Influence immunity
maintain the antimicrobial mucosal barrier in the gut
• Reduce the growth of pathogens
• Compete with “bad” bacteria
• Support gut health, which supports human health
• Many strains, many theories
• No consensus on dosage, frequency, strain type
• They are very expensive – and may not work
• Much research has been done in mice models
• Some research has assumed stool samples same as gut bacteria; not so
• IBS, other gastrointestinal disorders
• Obesity and the role of leptin and ghrelin
• Essential mineral and co factor for hundreds of enzymes
