Tell the students how you will evaluate their work. You can discuss as a class what kind of rubrics for scoring you will use to grade their work. Students should be involved with the scoring of each other's projects. Fifty percent of the grade could be given by the students and fifty percent could be given by you. 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.
If students cannot find the answers to their questions after they have searched extensively, have the students ask a geology expert by visiting the web page sponsored by the United States Geological Survey. 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.
