text: In summary, summer projects should be student-designed because students would be able to express their creativity, enjoy time, and express what they have learned during their summer break to their teachers and classmates. I take this position and encourage every teacher to assign student-designed summer projects based on my reasons stated.Cars are used everyday, and all around the world.
