I would use the above link of pictures of large gold nuggets found in Alaska as a hook for a lesson to discuss mineral deposits and the Gold Rush in Alaska. I would use it to show that minerals high in value can be found all over Alaska. They are created and reach the Earth’s surface through geological processes. We would then look in to gold mining and how human intervention brings such deposits to the surface as well.
The following link: https://www.akhistorycourse.org/images/geography/large/g1.jpg Would also let us see which different areas in Alaska have mineral deposits.
