One day your science teacher was exploring the rocks along the Potomac River near Washington, DC. He noticed different shapes, sizes, and colors. As he walked and looked at the rocks, something happened that transported him halfway around the world. When he arrived, he found a world very different than the one he knew well. So he decided to explore. And when he explored, he saw some rocks. He thought the rocks were trying to say something. As he listened very closely, he realized the rocks were trying to tell him a story of how the land in Chile was formed and how it is changing. Watch the video. Pause as you watch, or wait until the end. Then complete the graphic organizer. Use each word once and only once. When you have completed the organizer, read it to yourself. Change what you need to change. If you are not sure what to change, let your teacher know what you know and ask about things you are not sure.
