We went on a day trip to a fantastic place called the Grand Canyon. We took a helicopter to view the canyon. It is 277 miles long, up to 18 miles wide and 5000 feet deep. It is one of the original 7 wonders of the world. Do you know what the other wonders are?
Then we went to see the Hoover Dam. It is a massive dam which produces electricity. Do you know what a dam is and how it works?
