Pre-Building Brainstorm


Testable Questions:

  1. Which Balloon-Powered Car Design will travel 5 meters the fastest?
  2. Which Balloon-Powered Car Design will travel the furthest?


Independent Variable:


Shape of the car

materials

size




Dependent Variables:


distance

speed


Controlled Variables:


balloons

track





Things that can increase backwards force

Solutions to these problems

 Air resistance against the front of the car

cut a hole in the top so the air goes through
 


friction 

get the wheels to move smother, and faster.

 


uneven forces

make the car balanced


dragging

make sure nothing is too heavy for the car


not enough pressure

make sure the car isn't too light


Things that can increase forward force

Explain how your design will increase forward force

  Put one balloon inside the other balloon


With two balloons deflating at the same time, it will cause more air to be pushed out quickly, increasing forward force.


smaller car


It wont be too heavy so the balloons cant push it forward

blow the balloon bigger



the force of air will push the car faster and farther

bigger straw



The air will push out of the straw faster which



thicker wheels

The wheels will have the right amount of friction


List all the Materials you will need to bring in to build your car:

1.gatorade bottle

2.tape

3.bottle caps

4.scissors

5.CDs

6.straws

7.sticks

8.balloons




 

What part of car will this material be used for:
1.body
2. used to bind things together
3.wheels
4. used to cut things
5.wheels
6.axel
7.axel
8.power for the car






 

 

Materials and Procedures


Materials Used to Make Your Car (Also include the tools you used)


1.sticks

2. wire box

3.gatorade caps

4.drill

5.tape

6.hot glue gun

7.balloon

8.straws



.

Why did you choose to use this material?



1.axel

2.body of the car

3.wheels

4.used to drill holes

5.used to bind things together

6.glue things together

7.used to power the car

8.axel and where the balloon releases the air


Procedures – Written directions to make the car

Diagrams – Draw, describe, and/or insert a picture of what you did in that step (label if necessary)

STEP 1


  first we gathered all needed materials we needed.


 

our materials were:

*bottle

*straws

*sticks

*balloon

STEP 2


  put the wheels on a stick



STEP 3

         put the stick in a straw




STEP 4



          stick it to the car


STEP 5


place the balloon around a straw



STEP 6


place the straw and balloon on the car



STEP 7

then blow it up and watch it go..





 



 

Challenges and Technical Difficulties



Describe the problem. You may also use drawings.

Explain how you solved this problem.

Problem #1:

the wheels fell off all the time 


we placed rubber bands around the 

sticks so that they wouldn't fall off..

Problem #2:

The car wouldnt move


We fixed the wheels so that they would spin

Problem #3:

Air wasnt going through the car so the car went slowly


We cut the whole back side of the car out

Conclusion

 

   Are car didn't really work . are car was made out of random thing and could have been made durable.

   if i could change anything about the car i would have, made the wheels stronger. so that it had more forward force.

   One thing i recommend is that you should start as soon as possible, think clearly, and make your steps before you 

make your car.
