These posters are great if you are teaching the science standards for rocks or the rock cycle. I have a unit that goes along with this. It covers minerals vs. rocks, the different types of rocks, physical properties of minerals, and a rock cycle lab that includes food. We all know how much children love to experiment with food!!! Please enjoy these posters and check out the unit I have created to go along with it. If you have any suggestions please feel free to let me know!
