As the result of test shows, kids don't have comfortable control over the bike. As evident in the video, first, the kids don't have much balance on the bike, which makes it very hard for them to ride the bike comfortably. Second, when they entered the curved course and used the steering handle to steer to change the direction of the bike, they tend to lean towards the changed direction. For these reasons, the bike is very hard to ride, in fact it is not fun at all to ride the bike, which was the main purpose of the product. Moreover, as the data shows, the average score of candidates on the straight course was (), and on the curved course was (). Therefore, it is clearly shown that the bike needs to be improved in terms of its function. There are several improvements that could be made. First, the back wheel and the front wheel can be aligned straightly.

Second, the back wheel can  have a more stable or strong joint.

Lastly, stronger material can be used instead of bamboo.

Kids like playing together while cooperating. But the bikes without pedals are only available for a single person to ride. Hence, kids are not able to enjoy them as much as they could compared to riding together with a friend. Furthermore, as most of the toys or equipment in our school are for single person use, students don't cooperate or communicate while playing with those equipment. As consequence, they have less chance to develop their cooperation skills.

Teamwork is one of the most important skills students need to learn that is required in order to be successful in school and in the future. However, most of the equipment or toys in our elementary gym are only for a single person to use and they don't require any teamwork or cooperation to play with. Hence, students tend to only focus on individual success while playing. However, by making bikes without pedals for two people, students will be able to learn the ways to work as a group or a team. They will have to communicate and cooperate in order to successfully ride the bikes. For instance, they will have to communicate dealing with which direction they are heading, the speed of kicking or pushing the ground. As a result, students will be able to develop their communication and teamwork skills, which are important aspects in order to be successful.

Aesthetics
The skateboard has a black colored striped pattern on the deck. The pattern is simple, but has variations as the stripes are angled differently creating a cool vibe. The organized pattern on the deck makes it aesthetically pleasing. The wheels have two colors, blue and yellow. These two colors are blended, which makes it look very fancy and modern, even though there are only two colors. Moreover, the surface under the deck is also painted with yellow and blue keeping the color scheme coherent. Hence, the overall color contrast of the skateboard looks good. In addition, the deck was spray painted, and there was street styled text sprayed on the surface making it street styled looking. My product will also have a consistent color scheme consisting of two major colors, excluding white and black, thus that the product will look aesthetically pleasing. The tubes of the bike will have a simple, but organized looking pattern on the surface to make it look interesting and fancy. This will attract little kids as generally they like fancy looks. On the other hand, I won't spray paint my product in a street style, as street styles are not common or suitable for kids, as they are popular amongst hooligans or teenagers.

# data[].attributes.body
Material
The two major material of this product is plastic and aluminum. The deck is made of plastic and the fork is made from aluminum. By using these two materials, the price of the product is very cheap. At the same time, the product is very light weight. As the product is for kids, thus it needs to be light weight for the kids to be able to carry it around when playing with it. For my product, I will use a type of metal for the fork because most pressure and weight is applied to fork and in order for the fork of the bike to be stable it needs to be made from a hard solid material like metal. However, I won't be using plastic as it is not available in the design room and it is very hard to deal with at this level of manufacture. In contrast, wood can be cut into shape that I want.

# data[].attributes.body
Material/Customer
The frame, which is the biggest component of the bike is made from aluminum. By using an aluminum frame, the bike has lighter weight. As the product is for little kids, it is important that the bike has a light weight, in order for the kids to be able to pedal and move around with it. Moreover, as aluminum is one of the cheapest bike frame materials, the price of the product will be low. The product has a foam cushioned saddle on top of an aluminum base. The foam gives more comfort when seating on it, preventing the butt to heart as it absorbs the bumpiness while riding. Once again, as the bike if for little kids, it is important to have a cushion on the saddle as kids are more sensitive and they easily get hurt. For my product, I will also use an aluminum frame, to minimize the weight to make it easier for the kids to ride on and move around with it. At the same time, decreasing the price of manufacture. Moreover, I will also use foam cushioned saddle for my product for kids to be more comfortable while riding on it, while preventing butt injuries. But, I will have a thicker layer of foam on the saddle than the existing product to give more comfort, thus kids can enjoy riding.

Function
The function of this product is for kids to ride on them for entertainment purpose. Kids seat on the saddle and put their feet on the pedal in order to ride it. The paddle rotates on the chain ring, which rotates the sprocket of the back wheel and spins the back wheel. To change direction, the rider grabs onto the handlebar and rotates on fork of the front wheel, which is available to rotate separately from the frame, to steer the bike. There are two brakes, each on the front and the back wheels. The brakes work when pressure is applied by pressing the brake lever on the handlebar, then the brakes apply friction against the rim of the tires to stop the bike. For my bicycle, even though it will have the function to move and change direction, it won't have pedals neither brakes. The bike will move by riders pushing against the ground and it will be stopped by their legs pushing towards the opposite side of the direction moving. However, my product will have a handle bar and a fork that rotates separately from the frame, on the front wheel, thus that riders are available to change their direction.

Author John C. Maxwell says, "Teamwork makes the dream work." I believe that.

But as I mentioned in last week's "Tuesday Tip," a lot of people do not know HOW to build a highly effective team. So I referred to Laser Quest's 4 pillars of teamwork: Communication, Cooperation, Trust, and Fun. I wrote about communication in the last issue.

(P. S., If you've never played Laser Quest, I'd suggest you give it a try. My wife and I were initially skeptical - after all, adults playing a game of hide and seek, lasers and lights. But we had a blast and learned a great deal at the same time.)

But let's explore the second pillar of teamwork today - COOPERATION. It's got to be a part of any team that ever hopes to be successful. So what does it mean? And how do you get it?

=> 1. Cooperation Means Working Together ... For Everyone's Benefit.

In other words, no one has to lose for you to win. And yet I see just the opposite in so many organizations. There is more strife within the organization and amongst the members than there is from the outside. That is NEVER a sign of healthy teamwork.

You might take a look at your own team to see if it passes the first test. Is EVERYONE working together?

For example, when a third grade class was asked to name two famous brothers who made it possible for man to fly, one child replied, "Ernest and Julio Gallo." They obviously worked together ... but I'm not sure for everyone's benefit.

Likewise, I remember one person saying that he bought a dog that was a cross between a pit bull and a Labrador retriever. At least, he says, if he bites my leg off, he'll bring it back to me. Again, that may be working together ... but not for everyone's benefit.

In a healthy team, you realize that everything is connected. Success depends on your ability to create interpersonal partnerships where everyone takes responsibility for positive results.

=> 2. Cooperation Also Means Taking Turns.

Janet Stetson of Conneautville, Pennsylvania wrote, "The two most important ingredients to get along in this world are two things that you learned on the playground - sharing and taking turns."

Effective teams take time to take turns - to learn from each other. Ineffective teams are too "busy" for that "touchy-feely stuff." After all, they have their work to do and can't waste their time on "connecting" with other team members. It's a BIG mistake.

In fact, if you haven't asked each of your other team members about his/her greatest learning in the last year, you've lost out on a lot. You may never have the advantage of knowing what made such a big difference in someone else's job or life. And you may even have to learn the same lesson the hard way.

You see, so many of the answers that you need in life, at work, and at home are "out there." But you and your team members may not be "out there" taking turns in asking those kinds of questions. That's why I recommend my book on "Brave Questions: How To Build Stronger Relationships By Asking All The Right Questions." It will transform your team if you ask one or two questions every time you meet. And the book gives you 400 questions great questions to choose from.

=> 3. Cooperation Means Helping Each Other Out.

In other words, in healthy teams, you don't hear such comments as, "That's not my job... That's her responsibility... or... I just work here." You hear comments along the lines of "Yes, I'd be glad to help you... What can I do for you?... and... Is there anything else that you need?" There is an actual helping of one another rather than a passing of the buck.

It's not like the one man I heard about. He called the fire department to report a fire in his garage. The fireman asked, "Did you pour water on it?" The man replied, "Yes," to which the fireman said, "Well, there's no sense in us coming over because that's all we'd do."

Do you see the members of your team helping each other out? I hope so.

If you saw the recent movie, "The March of the Penguins," you saw an excellent illustration of this. When a fairy penguin - a tiny, defenseless thing of only a few pounds - was about to be attacked by a predator, it let out a cry, and several other penguins swam ashore to help him. Like a beacon, the squeal prompted the other fairy penguins to come in from the sea. Then the raucous chorus of birds began waddling toward their nesting area.

The predator didn't know that the birds always made their journey together - never alone. To be safe, they had to stay together. They had to travel from their hunting grounds to their colony as a team. They knew that "birds of a feather flock together."

When you think about it, every great achievement came as a result of people helping people. If a single researcher in a lone laboratory makes a monumental discovery, it was probably based on the contributions of hundreds of other discoveries and publications made by other researchers. Even the lone musician on stage was inspired and taught by countless others.

Erik Weihenmayer talked about that when he arrived on the summit of Mt. Everest on May 25, 2001. He conquered the world's highest mountain as one member of a team of nineteen hardy, determined souls. The one difference between Erik, and his team members and all the other people who have climbed the mountain over the years, however, was the fact that Erik became the first blind person to achieve this feat.

In a CNN interview on the afternoon of his success, Erik spoke of "team accomplishment." He talked about his sponsors, the people who were on the mountain with him, and the many who were not there but had prayed for him. "I felt like, when I got to the top, I was on the shoulders of lots and lots of people. It wasn't just me standing there."
Action: Listen to the way people talk in your group or team. Do you hear more "We" or "Me?" Do you here more comments showing a willingness to help, or do you see people holding back, hoping somebody else will do it? If you're hearing and seeing more of the latter, you need to have a meeting to talk about that very issue. You need to discuss how you are going to get past this roadblock.

The Importance Of Cooperation To Teamwork - Positive Communication Pro

"It is through cooperation, rather than conflict, that your greatest successes will be derived." Ralph Chavell Author John C. Maxwell says, "Teamwork makes the dream work." I believe that. But as I mentioned in last week's "Tuesday Tip," a lot of people do not know HOW to build a highly effective team.

I will make a tandem strider bike. The product can be produced through carpentry. A 3-D model of the product will be designed through sketch-up before going into the woodwork. According to my primary research, this is an important process for numerous reasons. First, in order for a bicycle to function properly, especially the joint between steering handle, fork and the wheel needs to be precise in size and design. Through the 3-D model, I will be able to visualize how the pieces are joined. Second, mistakes are very common during woodwork when there's no clear and detailed planning. Then during carpentry, I will be using wide range of equipment and materials to be able to build the bike, from hand tools to machines according to my primary research. According to my primary research, a survey that i've conducted from kids under Grade 3 in SSIS, I have found out bikes with characters from Disney and marvel are popular and favored by kids under Grade3. Hence, my product will have a characters drawn on the frame, as it is the major and the widest part of a bike. Moreover, my secondary and primary research told me that wood is the suitable material for me, as wood can be supplied by the design teachers and I am most experienced with carpentry as over the past years, I have made various products made from wood. Also, the survey conducted shows me heavy bikes are very hard for little kids to deal with and they are more likely to avoid using heavy bikes. Therefore, I will only use the minimum amount of materials needed to build a bike to minimize the weight of it. The product is for kids under Grade 3. According to my primary research, there are no rides that are for two students at a time. Hence, they have less time cooperating and communicating with other students. However, according to my secondary research, cooperation and teamwork are important skills required while working and in daily life in order to be success. Therefore, students need to learn and practice to cooperate and communicate. The success of this project will be a positive feedback and reactions from the students. The main goal of the project was for students to have fun while riding the bike with a partner and cooperate and communicate while having fun. To ride the bike, students must cooperate with each other. This means the success of the project depends on if they had fun or not while cooperating. So if students give a positive feedback in a survey, the product is a success.

I have blended design 1, design 3 and design 4 to create the final design based on my primary and secondary research and the design specifications. I have used the design of the main frame of the bike along with the back wheel fork used in design 1. All the four designs have met the design specification in terms of size, aesthetics and material. However, according to my primary research, the target audience, the kids in SSIS like and favors fancy designs in form and aesthetics. Design 1 has the fanciest frame design with a shape of parallelogram which is tilted at an angle, where all the other designs have a basic rectangular frame at straight angle. Even though, the frame design of design 3 is fancy with a triangular hole in the middle and an extended geometric shape, it cannot have a full sized character drawn on the frame because of the hole in middle, thus it doesn’t meet specification 1.1 as well a the other frame designs. On the other hand, frame of design1  has a wide available space for characters and wide range of colors to be used, thus will be favored by the kids.

I have used the design of the steering handle used in design 3. This is because the steering handle  of design three is curved. This provides the riders different types of grips, thus riders can choose the grip that they prefer the most according to its comfortableness. Hence, different to other designs, the riders will have a more comfortable grip of the steering handle, thus meets design specification 3.1 extensively. Therefore, the design of steering handle used in design 3 was chosen to be used in the final design.

I have used the saddle design used in design 4 for numerous reasons. First, the saddle of design 4 is easiest the build, but is the most steady, thus it is the most efficient and effective design. This is because there is a single long saddle available for two people, but other saddle designs are two separated pieces, which takes more time and effort to build as it has more joints and more cuts are required. Second, the single long pieces saddle design provoke creativity where other designs limits the kids creativity while cooperating. Therefore, the design meets the design goal to allow kids to learn communication and cooperation while having fun. This is because the long piece design requires more communication and cooperation for the kids to use as they are seating on a single saddle, thus they will have to cooperate in order to sit not he saddle. Moreover, they will be closer together physically, inducing more communication. On the other hand, other dieting have two operate saddles, which doesn’t require as much as communication and cooperation from the kids.

I have used tenon saw to cut the bamboo for the frame. In order to cut the piece, I first tightened up the vice to hold the piece stable and solid. However, as the piece was very long, I used four vices in hold the piece stable. Having the piece stable is very important because not only if the piece is not stable, you can't cut the piece at all or at a straight line, but also the piece and the saw may slip and cause injuries. To cut the piece more efficiently, I apply more pressure when on the push movement of the saw and apply less pressure on the pull movement since the cut happens the most during the push movement. When the saw was half way through the piece, there were lots of times where the saw got stuck. in order to prevent this, I asked my friend to pull the end of the piece to crate more space in between where the cut is being made.
Moreover, when cutting the bamboo, I avoided sawing through the node of the bamboo because it is harder to cut through as it is not hollow. So, instead, I have cut through the hollow part of the bamboo to make the job easier for myself.

# data[].attributes.body
I have used this technique when I was trimming/adjusting the edge of my fork, to create more space thus that it the wheel doesn't touch the fork (to make it roll). First, I have used a tenon saw to cut a line to prevent the chisel to go over the length I want. Then I placed the chisel at a parallel angle on the bamboo and used a mallet to hit the top of the handle. When using the mallet, I tried to hit the handle and make the contact with the middle of the mallet's head, which would transfer the most power to the chisel, thus I could more efficiently and effectively perform the technique. Also, I chiseled out thin pieces one by one. This was because chiseling thick pieces at once won't work, and the piece may crack over the length that I want, which means the pieces won't be useable anymore.

# data[].attributes.body
I have used the hole saw when I drilled holes on the frame with suitable sizes for forks to go through. I have also used the hole saw when I drilled a hole through the fork for the steering handle to go through.
In order to successfully drill the hole, there were numerous tings I had to be mindful of. First, I made sure that I was drilling at a straight angle/right angle. To do this, I asked my friend to see if me drilling and tell me if I was not drilling at a straight line. Second, I made sure I had control of the drill, and to do this, I used my left and to grab the top but of the drill with strength, to make sure the drill is stable, to, also to make sure that I was drilling straight. At the same time, I applied pressure with my left hand and a little bit of my body weight to push the drill through, since bamboo was very solid material. Second, when I was half way through drilling the hole, there were times where the drill got stuck. So I had to pull it out. Then when I started drilling again, I pressed the button and start the drill before the drill bit made contact with the piece. This is because

I have used a hack saw to cut a metal threaded bar. To do this, first, I used an engineer's vice instead of a regular vice that I was familiar with because I was cutting metal and regular vices were made out of wood, thus wasn't strong enough to hold the metal threaded bars. On the other hand, engineer's vice is made out of steal, which provides more stable and a stronger hold of the material being cut. Then I used a hack saw, instead of tenon saw, which I've always used to cut wood. This is because the saw blade of tenon saw is for cutting wooden material, thus is not strong enough to cut metal materials. Therefore, I used a hack saw, which is built stronger with a stable blade to cut the threaded bar.
There were few things that I needed to keep in mind to cut the threaded metal bar.

In my sketch-up model, the back fork had a design as shown in figure 1. However, the back fork in my final product has a different design as shown in figure 2.
This change was made because as I've mentioned above, after having a discussion about my project with Mr.MAC, I decided that I will make my product out of bamboo since it will have a unique aesthetics making it more appealing and there were plenty of it available for use. Also, as kids will be riding on the bike, the bike must be strong enough to hold weight of them for it to function and also not to break and cause injuries. Hence, decided to use bamboo to make the fork since it is one of the strongest wooden materials. Consequently, I came up wth a different design of the fork that is suitable for bamboo. Moreover, design of the fork didn't seem probable.

# data[].attributes.body
In my sketch-up model, the steering handle had a design as shown in figure 3. However, the steering handle of my final product has a different design as shown in figure 4.

This change was made because of lack of time. To make a steering handle with curved ends, cuts needed to be made at an angle and I would have had to use glue or dowel joints to connect the pieces. However, as I could not attend few design lessons as planned due to volleyball ACAMIS and holiday. Also because I got stuck in different parts of the process of making the bike, more time was consumed to make the bike. Therefore I made a steering handle that is simple in order to reduce the time required.

In my sketch-up model, the frame had a design as shown in figure 5. However, the frame in my final product has a different design as shown in figure 6. This change was made for the same reason for the change of back fork mentioned above.

Testing Method-The testing method is to have a course and have candidates to to ride my bike in straight line and curved lines. The candidates will vary in different ages from 5 years old to 15 years old, in order to test how different sized (height and weight) is capable of riding the bike. There will be three criteria level, unsuccessful, partially successful and unsuccessful, depending on the observation on the accuracy of how the candidates went thought the course.

Purpose of the test
There are numerous things that I can test from this test. First, most importantly, I can test if the bike is ridable or not, which is the main purpose of the product. Then, I can test how well the steering handle functions, in order words, how controllable the bike is.

Equipment list-
-12 corns
-a camera

# data[].attributes.body
Testing method-
I will have kids under grade 3, who are my consumer to sit on the bike.
Then I will have students from grade 6 to 10, that weigh from 40kg to 70kg to seat on the bike.

Purpose -
The purpose of this test the amount of weight the bike can maintain to make sure the bike won't break when kids seat on it and apply pressure, thus that the bike is safe to use.

# data[].attributes.body
Testing Method
-In this test, I will let go of the bike when it is standing, thus that the side of the bike drops and hits the floor. I will have the bike to hit different surfaces, including concrete, wood/gym, cement and surface with rocks. During the test, I will take record of if the bike breaks/cracks or not and how much  the bike bounces from the surface.
Purpose-
There are numerous purposes of this test. First, when kids ride the bike, and put away, they will not put the bike gently on the ground or stand it against a wall. Instead, they will be roughly throwing away the bike making it fall on ground and bump into walls. Therefore, I will need to test if the bike can endure this kind of rough treatment from the kids, and if the product has enough durability, thus that it is appropriate for kids to use. Second, this test simulates how the bike falls and what happens after the bike falls, and by measuring the distance it slips and bounces off from the ground, I will be able to notice if there is any safety problems when the bike falls.

The product, which is a bike doesn't have a saddle, thus riders sit on the frame to ride the bike. This makes the bike look as if it is an incomplete product, as a result, the quality of the product decreases, which eventually means it is less likely to attract the kids to ride the bike.

Moreover, a layer of cushion can be added on the saddle or the frame that the riders sit on. Since the material of the frame/saddle is very hard, when kids ride on the bike they feel uncomfortable, moreover they might get hurt when they ride on a bumpy surface. Hence, a layer of cushion of sponge on top of the frame/saddle will make the bike to be comfortable and safer.

The evaluation of the product against the specification in D2 clearly shows that the aesthetics of the product is more towards a failure. Although the bamboo theme is aesthetically pleasing, it is not appealing to kids, who are the target audience of the product. Two improvements can be made to solve this problem. First, since bamboo is not suitable for painting, colorful stickers could be used to decorate the bike to have a fancy aesthetics and color scheme, making it more attracting to kids. Sticker machines in the design room can be used to design and cut out stickers. Moreover, stickers can be easily bought in stationary shops or on Taobao. There are wide range of stickers that have attractive designs, and it is also very simple to stick stickers on to the bike, hence this is a very simple, but an effective solution. Second, in more specific, character or hero stickers can be applied onto the bike, which would be more appealing to kids.

# data[].attributes.body
I believe the product has achieved the goal from the design brief. Firs more than one kid were able to ride the bike at the same time. They had to communicate with each other in order to balance, match the timing of when they push against the ground. Hence, the product would clearly help the kids to improve their teamwork and communication skills while riding the bike, which means the main goal of the product was successfully achieved. improving these skills will help the kids both in their school and out of school as communication and teamwork is essential everywhere in order to be successful. For instance, when kids are involved in group assignments, they would need to communicate with each other to successfully finish he assignment. Second, the kids really enjoyed riding together with friends. They were playful with each other while riding the bike and since it was more challenging to ride the bike a friend, kids seemed to be enjoying more. Therefore, they will be able to have more fun while riding bikes.
