Replicating an Artifact Corrections

We goofed! One of our amazing collaborators at the Connecticut Science Center brought an important error to our attention. In our Solid as a Rock: Replicating an Artifact unit, we incorrectly identify soapstone as a sedimentary rock. Soapstone is a metamorphic rock! We have made corrections to all of the affected pages and have created PDFs of those pages that you can download here:
