text: In summary, having a student-designed project rather than a teacher-designed project will greatly increase how much each student learns over the summer. This is because the student will be more motivated, happy, and relaxed if it is a project that the student is interested in. If summer projects are included in more schools, hopefully they are student-designed. This can be a good opportunity to make students have something productive to do during their summer break. With a student-designed project more students will have a better work ethic, there will be better results, and students will be more excited to work on the project.Within countries around the world people are coming together, whether it be the polititians or the citizens, they are all beginning to put an end to the use of cars on a daily bases. In Germany there is a suburban city where the majority of its' streets are relatively free of cars and the residents of this "car-free" city seem quite content. Germany isn't alone in wanting to rid the world of cars along with the pollution and stress it brings, Paris, France is another of the handful of places that would prefer to begin an anti-car revolution. There are days in Paris that, when the smog is too much to bare and the air is hardly breathable, they are forced to enforce a partial driving ban. After about a week the air was noticably cleaner. While Vauban, Germany and Paris, France have joined the fight in kicking cars to the curb in their own particular ways, three cities in Colombia have also decided to become a member of the ever growing "car-free" city club by starting a program that sponsers a car-free day once a year.
