Here are two publications specifically geared to homeschooling that are open to submissions, but don't pay.
* The Old Schoolhouse Magazine is the trade magazine for the homeschool community. Its curriculum site, SchoolhouseTeachers.com, is looking for writers. Needs writers to create educational materials for any grade and almost any subject. You don't have to be a homeschooler, or have a specific degree or background--they are looking for mastery of a subject, not specific qualifications. You also need to love to write from a Christian worldview. Offers free advertising and free membership to the entire site for your family. Contact Executive Editor Bonnie Rose Hudson at firstname.lastname@example.org for more information and to submit ideas for consideration.
* Molly Green Magazine is owned by The Old Schoolhouse Magazine. Their goal is to assist their readers and members in crafting a home-oriented lifestyle by focusing on all things HOME: HOMEsteading, HOMEkeeping, HOMEschooling, and HOMEindustry. Open to articles 800-1,300 words; blog 500-1,000 words, and e-Newsletter 400-600 words. Currently looking for articles on homesteading or home industry, but will consider articles about homekeeping or homeschooling. Email article queries to email@example.com and include the words "Article Idea" in the subject line. Visit www.mollygreen.com/mollyblog and read the digital version of the magazine at www.mollygreenonline.com for examples of the type of articles they are looking for.
