Students should be encouraged to think, design, and build as much of their project as possible. If outside assistance is necessary for dangerous or logistical tasks (ex. operating power tools, sourcing materials, etc.), parents, teachers, or other mentors can assist, but the students should still direct the process. Parents can also provide opportunities at their homes or local libraries for teams to work together. Encouragement is always needed. Younger students will likely need more guidance but you should still let them do as much as they can. If students use outside assistance, they should give credit in their logbook.
