Inform the students about the limitations to the questions that they can ask the geology expert. Students need to document where they found the information by recording where it came from. Encourage the students to find at least three informational sources for the answers to their question. Have them evaluate the information that they found to see if there is anything contradictory in the information between their three sources. Have the students share the information that they found with their group.
Students can either create projects made by the entire group, small groups, or individually.
