Free "History of Science" Lesson Plans for 6-12 gr.
Written for teachers, these are interdisciplinary lesson plans. Some consist of only one or two activities, while others could fill a semester or more. The lessons I've read are clear, fully explained, and include extensive bibliographies. Most are written with the expectation that students will be working in a group. They could a be a valuable resource for a homeschool science club.
National Geographic Xpeditions: online & offline geography activities and lesson plans
There are 2 ways for homeschoolers to use this website: parents can use the included lesson plans (grades 1-12 are represented) to teach about specific topics, or students can explore the virtual "Xpedition Hall" independently and learn about mapping and geography. The lesson plans are creative and use materials from respected scholars and artists. The Xpedition Hall requires reading, and is best suited for middle school age or older. The tasks in the Xpedition Hall emphasize understanding and applying geographic techniques and information, not rote memorization.
Teacher's Resources from the Library of Congress
The Library of Congress has helpfully linked primary sources, lesson plans, activities and even professional development for teachers on this page. From here, you can find a wealth of lesson plans, primarily relating to American History, but literature and culture are also well represented.

Scholastic Lesson Plans: a searchable, free collection of plans and projects
Looking for ideas to support a new interest, or a whole unit study? There's lots to choose from here! There are hands-on science projects, multimedia-supported lessons, book club ideas... Most are designed for classroom use, but all the lessons I've looked at are very well-suited to homeschooling.
There is the most available for elementary students, but pre-k through 12th grade are represented. Interesting to just browse if you're feeling uninspired.
Free, Creative Math Lesson Plans from the Math Project Journal
Includes lessons for Pre-algebra, Algebra, and Geometry. Some relate to popular culture, others mythology, all involve a hands-on component. Could be a way to add some fun or at least novelty to a topic review.

BBC Primary School Languages: French, Spanish & Welsh
The BBC has fun resources to help elementary aged kids learn French, Spanish and Welsh. These are the first free resources I've found that go beyond the absolute basics (i.e. colors, numbers, and a couple phrases) while remaining fun and appropriate for younger kids.
"Fieldwork" hands-on high school level marine biology for/by homeschoolers
A homeschool mom is generously sharing the marine biology course she's developing for her kids. Alas, the marine biology course isn't for those of us who live far from the ocean, but it's a very cool program for coastal families.
