when racing you need to make it fair to make all the cars start at the same point also no objects in the way of the co2 cars.

# data[].attributes.body
when testing uses your different prototypes to see what's best the fastest lightest and see how you can improve.

# data[].attributes.body
You want to make it fair so make the ramp even and make sure they all start at the same time so it is fair. You also don't want to have anything in the way of the CO2 cars.

# data[].attributes.body
when your done with designing, building, and testing your cars, you now have to set up an equal race. make sure it is completely fair and that there are no variables giving other cars a leg up.

# data[].attributes.body
Here you will want to have your final set up and your satisfied with your car when testing make sure all cars are raced equally and a timer is set don't forget about the C02. Make sure everything equal and no variables

# data[].attributes.body
when testing it, you need to make sure to do a few test runs to make sure your design is efficient. make sure to have a surface that works (probably on tile or hardwood, just something other than carpet) for you. adjust your design to go faster if needed during the testing process.

# data[].attributes.body
When testing your car you will want a smooth surface to test on you will also want to have timers to time your car then you can adjust your wanted speed until satisfied

# data[].attributes.body
When designing the car you want to make something that's light weight so I would sketch it out first and then make sure it will be aerodynamic so it can be heavier on the back of the car and lighter at the front and make sure it has a point so that the force when sped up can glide easily onto it.

# data[].attributes.body
When you finally get ready to put your car on the race track the carbon dioxide on the back of the car will help to start the gas and push force over the car making it speed up you will also need a track that is long and smooth and when your car goes fast enough and move smoothly that's how you know your project is successful.

# data[].attributes.body
Fairness, following the instructions, and being a good sport are key to having a successful race. Fairness and following the instructions make it so there is no cheating and the results of the race only show who won fairly.

# data[].attributes.body
To make the best of your testing time I think you need to do couple of test drives an see if all of your materials are efficent enough so that they won't break down I would say it works best on a smooth surface and not rough if you want the best results and then when you feel that the cars materials are good enough to test your then good enough to get started.

# data[].attributes.body
When you start the process of building your CO2 design. for this process woods works the best, you will need 4 large wheels 2 for the front and 2 for the back but to make sure you have all of these materials correct try making a plan and sketching it out and then put your car together.

# data[].attributes.body
When you start to test your car, make sure you set a timer and distance to see how fast your car will go. From there, you can adjust and fix the flaws in your design.

# data[].attributes.body
Before starting to build your car, you should draw out your design. Then you can start cutting and shaping your design onto your wood. Keep in mind that you want it to be light, aerodynamic, and have good wheels that keep your car moving fast.

# data[].attributes.body
for the co2 test it needs to be fair to where everyone has a fair chance. for example the start of the race everyone needs to be evenly put out. and another example is that threw out the race the track needs to be at an even angle so that one doesnt go faster than another.

# data[].attributes.body
to form the best test you need to be careful not to break your build so you need a protected test. for the test you will also need the right surface to be on like for starters you would want to be on a completely flat surface and a surface that doesn't have resistents.

# data[].attributes.body
when racing co2 car make sure everyone has the same amount of co2 and that all the cars start at the same time

# data[].attributes.body
When its to race the CO2  you need to make sure everyone has the same amount of CO2 and all the cars fit all the rules.
All the cars need to be on flat ground and nobody gets any head starts.

# data[].attributes.body
preparing for the race you should make sure your car is in the best condition. You should race fairly and have good sportsmanship. You have to follow rules like no cheating, sabotaging, and more. Be competitive but don't be a sore loser or too competitive. Remember its just a race.

# data[].attributes.body
When you test your CO2 car, you should test it for the time and distance. Then you need to improve the results. you will keep improving and repeating the tests until you are satisfied with the results.

# data[].attributes.body
For racing, try to make your car the best it can be to knock out the other competition and win the race. Good sportsmanship is also important as well as fairness.

In order to have a fair competition and race, a few things make it possible to do so. Such as no cheating, following the criteria for the cars etc. These will allow for more accurate results and make it more fun and enjoyable for everyone. If everyone shall follow these rules it will even out the playing field a bit more to let only the top cars succeed in this race

# data[].attributes.body
dont cheat, if you cheat, it only shows how bad you are at being creative. (im sorry but its true) If you dont cheat, and dont win, have good sportsmanship, if you win, dont brag, it only makes others feel bad

# data[].attributes.body
When you test your CO2 car time it for a set distance then time it. the reason you want to test before you race it is because while testing you might find some major or minor design flaws.

# data[].attributes.body
The best method for testing a CO2 car is using a flat surface. This will indicate whether or not the car is able to move successfully. Something should be used to measure the speed of the car at the end of the test. Keep modifying and improving until the results are promising.

# data[].attributes.body
When building a CO2 car first you will get the materials. the materials may include the wood that the car is made out of, two large wheels, two small wheels, an axel which will help the car get speed, and the CO2. you build the car. you will need to use a few tools.

# data[].attributes.body
test in an enviornent that will no harm your car

# data[].attributes.body
When testing your Co2 car you first want to make sure your axles/wheels spin freely, and make sure both the front and back wheels are pointing straight. And always make sure you have a safe way of stopping your car so that it does not break or break anything else.

# data[].attributes.body
To race co2 cars you need to make sure everybody's car has an equal amount of c02 (because if one has more it could go for longer). Also make it so the place where you are racing on is equally long and equally flat in all places. Then when you are actually racing make sure that the cars take off at the same time ( no head starts).

# data[].attributes.body
when building the co2 car, the first thing you should do is sketch your design onto your block of wood. then you can cut it out based on what design sketch you went with. you want to make sure that you have an aerodynamic car, so make it as lightweight as possible, and not very high off the ground. when making this, note that round cars move a lot better because it allows air to flow over it with very little disruption to its stream.

# data[].attributes.body
when testing you want to make sure your car is the lightest weight it can be and is the fastest it can be like the pointed front

# data[].attributes.body
To test it roll it on something smooth or just the ground and make sure everything is working fine and fix anything you need to.
Also time it and see the time and see if you can improve the speed at all

# data[].attributes.body
When making a co2 car you will want to make the front of your car aerodynamic. You will want to make it aerodynamic cause the wind will not be able to catch the car and slow it down. When getting all the materials for your car you have to be careful of what you get. When getting the wheels you have to check if they can rotate freely.

# data[].attributes.body
make sure all the info you gathered is true before building, that way you know what not to do to your car. build the car so that the least amount of drag occurs

# data[].attributes.body
You should test your car during the prototypes to make improvements along the way. Test the friction of your wheels, the drag of your car, how fast it goes, the weight, and anything that could be adjusted. Keep testing and improving until you are satisfied with your build.

# data[].attributes.body
During building your co2 car, you want to test lots of things so that you don't get to the race and realize it doesn't work. One thing you could test is the wheels, and making sure it moves freely and doesn't stiffen up. Also you want to make sure the wheels aren't going to fall off or that your car is going slower somehow.

# data[].attributes.body
A good way to test your car would be how resistant it is to air. A way to test your car would be by taking a fan at home and putting a peice of wood behind your car. Next you are going to want to place the fan in front and facing the car. Next turn the fan on and see how long your car can stay not touching the wood when you push it forward. This will give you a good idea on how air resistant your car may be during the race

# data[].attributes.body
for the co2 build it would be best if you put all your ideas and mixed them all together forming one big accurate build. for the shape you would want the most smoothest design when going at high speeds and for the wheels you would want them to make the build the fastest.

# data[].attributes.body
To test a co2 car first roll it on a flat surface and see if it goes strait, if that fails to work then adjust your axles. also make sure your car can make it to the finish line in a good amount of time.

# data[].attributes.body
When building a CO2 car, the design process is this. First, you will need to sketch your design out and get an idea of what your model should look like. Next, you start the building process by shaping a wood block into the desired proportions. While building, it is best to keep in mind that light weight and freely spinning wheels will help the car go a lot faster.

# data[].attributes.body
You want make sketches first about it and then test it out early an not wait until it is due. You also want to have a smooth car all around and have a some what pointy front and have the air just brush off the car. Then you want to add the wheels but make sure they are on it and they are sturdy so they dont ruin the whole thing by either not moving or falling off

# data[].attributes.body
To test your co2 car you can roll it on a smooth surface and it should go straight if the car swerves or turns all over the place you know that the car probably should get looked at, since the wheels could be misaligned which could cause a huge problem in a race. And of course see how fast its able to go by rolling it down a slanted surface.

# data[].attributes.body
Aerodynamics and light weight is the key for making a co2 car if you have a light weight car it will go faster cause if its too heavy it wont move as fast. for aerodynamics the car should be sleek and have a flatter shape so the wind wont slow it down

# data[].attributes.body
When you are building your co2 car you always want the wheels to spin freely, You also want the car to be very light. This means you should use wood and remove much of the material. This will allow the car to move much more quickly and weigh it down less.

# data[].attributes.body
You want to make your design not as heavy, because if you make it heavier it will make the car slow down. If you have a lightweight car it will fly with the wind and go a lot faster.

# data[].attributes.body
when building a Co2 car you should start with a idea a sketch it on a piece of paper. next you could make a prototype of the design with foam or any other kind of soft easy to work with material. You want to do this so you can make sure you like your design.

# data[].attributes.body
Isometric drawings a great way to explore different designs and visualize what your call will look like from different angles. They are 2-dimensional drawings of your car at a 30-degree angle which allows you to see the side, front, and top of the car.

# data[].attributes.body
When your building a co2 car you should start with multiple drawings, and label the drawings with important details. Then take the best few drawings and make prototypes to test. Test the all the important factors and improve them or start over. Then make a final design after making the ideal prototype

# data[].attributes.body
When building make sure you use light weight materials that will not slow you down like basswood is a good option and little material possible

One of the best ways to build your co2 car

# data[].attributes.body
First, in order to develop a good c02 car you are going to want to make a front the is aerodynamic. Make a car that is low to the ground and has as little material as possible. This will help reduce the drag from the wind and therefore allow your car to move faster. Again another improvement you could make is by adding a slight ramp to your front. This will allow for the air to pass right over your car and allows you to have a fast car.

# data[].attributes.body
having a pointed shape of the car with allow it to go faster and for more air to surround it making it go faster. having the more weighted area on the back could lead to the car having more speed and having a lighter car can take more force and go quicker when its at the point at the top which will lead to your car being a success.

# data[].attributes.body
a good design for a co2 car to be more fast and to not lose speed are like making a sphere type design making it lose less energy to the build when set off.when it doesn't lose as much energy it will go further.

# data[].attributes.body
Something you can do to make your car faster and have less drag is something called golf balling. All you need to do is make little circular pits all around. It reduces the weight of your car and helps minimize drag.

# data[].attributes.body
To start the building process you want to plan it out and design it first. After youve done that make a drawing or plan out what you are going to do. The next step is cutting and shaping the car, and hopefully making it lighter. You also might want to test to make sure that it drives and making sure the wheels rotate.

# data[].attributes.body
to build your co2 car you want to make sure you know the best way to actually build it and to get the supplies for example when you come up with your design it needs to be make-able and possible without costing two much money. If you want it to move faster make it out of something lighter like make it out of wood instead of a heavy metal.

# data[].attributes.body
when making a CO2 car you want to make sure that your axles that your wheels will be attached to can rotate freely. You will also want to first cut the rough shape of your car and then sand it down to want you want.

# data[].attributes.body
You want to make your design not as heavy, cause if you make it heavier it will make the car slow down. If you have a lightweight car it will fly with the wind and go a lot faster. You will want to make your car flatter and not make it big. Making the car flatter will make the wind not slow it down, cause if you had a not flat front the wind will catch your car and make it go slower.

# data[].attributes.body
Aerodynamics is a key factor for maximum speed in a CO2 car.  Aerodynamics means the forces and airflow involved in the movement of an object through the air.   Putting aerodynamics into this design would look something like the above model.
A curved top and thinner middle section will prove to avoid drag (which is the effect of using a normal block shape)

# data[].attributes.body
when designing a Co2 there are 4 forces enacting on the car they are thrust in the front, drag in the back, downforce on top, and friction on the bottom.

# data[].attributes.body
What you will do first is you will need to sketch on a piece of paper what you want the CO2 car to look like. The design should be aerodynamic. By making it aerodynamic it will go faster. To make it aerodynamic you need to make the front of the car lower than the back of it.

# data[].attributes.body
the wings of a plane are curved at the top and flat at the bottom, a car is also built like this. the air goes faster over the top and slower under the bottom, creating less drag, making the car/plane go faster than if it was built differently.

# data[].attributes.body
rail design rail’ designs are used in the construction of dragsters. The advantage of using rail designs is that they have low mass. However, this benefit can also turn into a disadvantage, since dragsters with such a design have a fragile body.

# data[].attributes.body
CO2 is carbon dioxide.
Factors that effect the speed are mass, friction, the amount and speed of gas escaping the CO2 container. Another factor is how well the car passes through the air.

# data[].attributes.body
for the design process, u need to minimize the weight and make the car aerodynamic with a pointed front and a light body so the car can go its fastest potential.

# data[].attributes.body
Make it have a decently sharp front so the air wont slow it down and it goes right over and I will try to have even/stable wheels so it does not fly around

# data[].attributes.body
you want to plan the shape of your car to be aerodynamic which would be a symmetrical shape like a sphere. That would allow air to blow over the top surface car without too much disruption

# data[].attributes.body
To make the CO2 car go the fastest it can, it is best to go with aerodynamic. When the CO2 car has aerodynamic features it goes faster because it lets the air flow over its suface with no disruption or causes to make it slow down. You also can lessen its load by making it smaller or lighter.

# data[].attributes.body
For a co2 car to work properly we are going t need to make it light. Making it light will allow for more speed to come out the car. This works because when the co2 car starts to go it will have to push less material therefore allowing it to get to a faster potential then before. Also, making an aerodynamic car is also good. Aerodynamic means that the car   reduces the drag from the air that the car is cutting through.

# data[].attributes.body
first, sketch some ideas about what you want your race car to look like. you could also make a "working drawing", which is a precise 1:1 scale drawing that describes it and its features. the size of your car usually determines how fast it goes- bigger= slower and smaller = faster.

# data[].attributes.body
Its good to use something with a slimmer shape with holes in it so it can move through the air easier (aerodynamics) and go faster. You also want something relatively light so it doesn't take as much force and can move faster.

# data[].attributes.body
tips and good ideas for the design process are to minimize the amount of weight your car has the more mass it has the slower it goes. Minimize friction the more the car drags the slower it goes.

# data[].attributes.attachment_caption
This is an example of a car that is very aerodynamic.

# data[].attributes.body
To make the car go the fastest you need to make it aerodynamic. To do this, you need to create a symmetrical pointed front, this way there is much less wind/air resistance to slow the car down.

Before making your final "production model" out of wood, you should make one or more prototypes of your car out of foam. Why? Foam is cheaper and easier to work with so you can learn which design features work/don't work faster.
