As a teacher and homeschool mom, my winter lesson plans revolve around science themes. With the holidays over, it's a good time to explore physics, earth science and biology themes. Why not check out these printables for your students? The Detroit Science Center closed in 2011 and has since reopened late in 2012 as the Michigan Science Center. The center website offers free printable lesson plans and activities. Teachers, homeschool families, kids and parents will love the science-themed coloring pages, puzzles, games and learning extensions. Here are lessons on astronomy and educational astrology from Michigan Science Center's Dassault Systemes Planetarium. These lessons work well for special needs students because they are hands-on.
