The WebQuest can be used to supplement student learning during a rocks and minerals Earth Science unit.
Just one of the many positives of this WebQuest is the "Social Action" aspect of the WebQuest. The end project, the poster, allows the students to make a real world connection to their learning, and empowers them to take a stand either for or against a mine next to their school, and use their research to back up their opinion.
A possible extension activity would be to have students co-construct letters to the mining company, either in support for or against the mine next to their school. This activity would be an opportunity for students to practice formal letter writing skills and persuasive writing techniques.
Below are several resources containing image credits from this WebQuest, the New York State elementary science learning standards supported through this WebQuest, the rubric for grading the student posters created at the end of the WebQuest, and the worksheet that was constructed to be used with this WebQuest.
I have also included my lesson plan that I wrote up to go along with this WebQuest.
