text: Being able to choose what you're working with will make a project more enjoyable. Most of the time, teacher-assigned projects would have all the students doing or researching the same thing. While this makes the assignment easier to grade and gives everyone a common goal, some people want to look somewhere else. Choosing your subject could bring about interesting results and give you a new interest rather than just being given the generic science project where you monitor and grow a small plant for x amount of time. Working on something you, personally, picked out could also inspire you to put more work into the assignment.
