Here are the online resources I used to pull our unit together....enjoy!
Homeschool Share unit and lapbook for Twinkle, Twinkle Little Star
Man on the Moon: A Space Unit for preschoolers from Musings of Me.
A is for Astronaut Tot Pack from Totally Tots
Astronaut Preschool Pack from Homeschool Creations
Astronaut Letter Writing Practice and Poem from Spell Outloud - I printed out this poem and accompanying graphics, cut out, laminated, and glued felt to the back to use these as flannelgraph pieces.
Coloring page of the planets from Coloring Castle - This is my favorite planet coloring page because it is so versatile. I printed this out, let the girls color the planets, and then we made mobiles by taping them to fishing line and hanging them from plastic coat hangers to make mobiles. You could also have your kids color these, cut them out, and then affix to their correct orbit paths.
Homeschool Share's Outer Space resources - tons of great stuff here!
Jimmie's Squidoo Lens has tons of printables for a space lapbook.
Learning Pages A-Z - This is a great site with some really nice resources, and it's free to join. Check out their space theme for lots of printables. We used their Planet Cut-outs. The kids colored these, cut them out and attached them to a large piece of black butcher paper to make a space mural. Throughout the unit the kids will add things of their choosing to the mural - asteroids, comets, meteorites, rocketships, etc.
Planet 10 - Choose the 1.0 Solar System option. It's a virtual fly-through of our solar system, complete with rotating planets revolving around the sun on their orbit paths. Fascinating site. (We haven't tried the 2.0 World Builder option but will eventually.)
