Today, since we are on a block schedule, we didn’t have any 8th grade science classes.

Students took notes today on Disturbing the rock layers and Gaps in the geologic record.

Today students worked on vocabulary words for our new unit or they worked on Zooniverse.org classifying insects.  Each groups will have the opportunity to do both activities.
