This product includes all the words and definitions that are set out for the 6th grade science curriculum in the state of Utah. I've included 3 sections. The first section is the word with an attached picture, most of the pictures come from the NASA website and do not infringe on copyright. The second section is just the word. The third section has the word and definition.
Use any or all of these when introducing the words and building a science word wall in your classroom. I also have a companion activity for students to review and learn the words and definition.
