By: Alivia CollinsMy CO2 Car

I would like my car to be the fastest!

Define the Problem

This is my design :D

I actually wanted flames on my car but it ended up looking like a bird. So now my car is a bird.

Brainstorm

Research These are some of the websites I used

1. Flame car

2. Colored pencil

3. Bird

Ideas?

I chose the bird car because I thought it would be the lightest out of the three and I also thought it would be a different thing to choose.

Best idea!

My prototype turned out good but I didn’t take a picture.

I painted my car orange and red like a cardinal.

Prototype

My car ended up going 40.5 miles per hour and winning 1st place!

Testing my car

This is the end of my presentation!
