The Project Guide is your place to connect to our entire collection of Ohio 4-H project books for the year. Each project book contains information and activities for members to explore as an organized group project or at home under the guidance of a parent or interested adult. When choosing a project, consider your interests, background, what is necessary to start the project, and the resources available to help you complete it.
