I like the idea for HOW to make/bind a different kind of book. Very little materials needed, and kids can do by themselves. They can staple paper inside. Lap Book, Spaces United, Spaces Lapbook, Lapbook Ideas, Spaces Maze, Rockabye Butterflies, United Lapbook, Flip Book, Rockabi Butterflies
Also on these boards
Lapbooks on Space; Black Holes, Asteroids, Astronauts and More!; Sun, Moon and Stars and Planets! Also good astronomy links at the bottom of the page.
