CO2 Cars

In Room 15 we are designing our CO2 cars. Instead of racing each other in our class we are going to go  BEYOND just our class we are going to invite Room 5 and Room 6. Last week we started to design our cars on a piece of paper and a small group of others wrote a letter inviting the two other classes. My CO2 cars name is going to be called The Flying Unicorn. My CO2 car is going to be pure white with blue racing lines on the side, in words The Flying Unicorn, a lightning bolt and a small picture of a grey unicorn. On Room 5's blog they have made a sticky when everybody can say what makes a winning CO2 car. If I had won the CO2 car race I would be amazed and very surprised.
