Children love learning about outer space. Here is a zip file chock full of ELA, Math and Science activities to support your space studies. There are over 20 pages of lessons that can be used as independent projects or in cooperative learning centers. I have used them with my classes with great success.
For some example of activities look at my Mix It Fix It, Landing on the Moon, and Space Place Project. These are included in the packet. Altogether, there are sixteen activities to use with your students.
