Aggregates Poster

Aggregates (sand, gravel and crushed stone) are the most mined materials in the world! The front of the poster depicts some of the ways aggregates are created, such as alluvial deposits from rivers and streams and crushed stone from hard rock deposits, as well as photos of some sample aggregates. The back of the poster contains four aggregate-focused activities to be photocopied and used in classroom instruction. Activities include use of maps, math, rock identification and a rock cycle fill-in-the-blank. 22” x 17” 2-sided poster
