for my 9th project I did hot wheels because that it one of the only project I have not done and it is relative new in the class room. During this project I learned the importance of making sure every thing is together correctly so the project goes as smoothly as possible. Out of the 7 standers this project ties to are Empowered Learner because I made my track how I wonted it, it also ties Global Collaborator because I put my projects on my website. A challenge I over came was making sure my track was made so my car would not go air born accept at the end. I over came this challenge by remaking my track until it worked. If I could change one thing I would change the length of the track so it would be longer and the car could do more stunts. the carres my project ties to are engineering and construction.
