Unit 7 Reflection

Unit 7 was on the skeletal system, including types of bones and joints and structural aspects of bone. We first learned about some of the disorders of the bone, including degenerative ones like arthritis and rickets and structural ones like scoliosis and kyphosis. Then we moved on to bone remodeling, which explained the physical characteristics of bone as well as its function. Bone density is important because dense bones equates to a stronger body support system. Osteopororis is inevitable, but leading a healthy lifestyle can certainly slow bone loss down. One of the ways we keep our bones fresh and strong is through bone remodeling. Osteoclasts strip away bone tissue and replenishes the blood with calcium. Osteoblasts rebuild the bone by secreting collagen.

Next we moved on to bone fractures and repair. Repairations include fibers reconnecting the bones and bone replacing cartilage.

The last sections was on joints. Joints can be classified by their mobility and how two bones are joined. Synarthroses are immovable joints, amphiarthroses have limited movement, and diarthroses hare filly movable joints. Structurally, there are fibrous, cartilagenous, and synovial joints. The typical joint you would think of is synovial synarthroses, such as he knee and elbow.

As for my new year's goals, I am running semi regularly with my friends now, but i still need to do my fill of resistance training. I just got a three month gym membership so hopefully I make the most out of that before summer starts! My diet is doing okay--I don't really think it's especially bad or great right now. I've cut junk food but I still like my carbs. 

20 Time is going smoothly, my project is essentially done but there's always more I can finess.

Hi friends! Thanks for visiting my progress report again :)

To further my project, I've been researching the price of raw materials and pieces of technology that are needed to create one bottle. Some considerations and notes:

• Since the bottle has moisture sensitive technology, the water bottle cap needs waterproofing.

• The water bottle set will be comprised of a bracelet and a water bottle, with the bracelet connecting to the bottle via magnet.

• The bracelet is primarily silicon, adjustable by disc magnets to fit all wrist sizes. Its function is to remind the wearer to drink water periodically; keep the reminder with the person as opposed to solely on the bottle.

• Reminders will come from bottle itself and the bracelet.

Cost of materials per bottle:
bluetooth chips - (receiving and sending) - $5
glass thermos bottle - $4
stainless steel - $0.06
thermocouple (measures temperature) - $2
processor - $6
touchscreen back-glow display - $7
silicone rubber - $0.10
plastic - $0.20
disc magnets (6) - $0.48

cost per bottle: $24.84

Because the cost is around $25, the price of the bottle should be around $90 to make adequate profit.

Finding the base cost of materials was actually pretty difficult--I ended basing my costs off of what I saw on wholesale websites that were kind of sketchy.
The accessibility of information needed to accurately calculate the costs was a bit of a set back, but I just averaged out what I saw and estimated the best I could. The only actual setback is HOW HARD BLOGGER IS TO USE. The pictures in post2 really screwed up my blog formatting. I just have to deal with it and do the best I can to make my posts un-ugly.

Through this project, I've learned that I am maybe not cut out for engineering because I could not figure out of the life of me how bluetooth works and how to make it, though I did manage to find some components needed to build it.
