Inventors are problem solvers, so learn to look at old problems in new ways. Make sure all your logs and drawings are neat and complete. Always use proper spelling and grammar. Use a dictionary or thesaurus if needed. Try to make your invention work as efficiently as possible with as few parts as necessary to accomplish the task.
Inventors solve problems economically.
Think about the cost of materials involved and production time needed before you make your invention. Be certain the invention is safe to use and safe to make. If tools are needed, get permission from your parents to use them, and ask for help if it is needed. Maintaining a detailed log is essential to the success of your invention project. A log is a dated, written record of your ideas, research, experiments and tests.
