Our problems have to do with some of the Wonders we’ve been discovering about our world during our global research project…

The Great Barrier Reef is the largest natural structure in the world.  It is 13,171 miles long.  The Great Wall of China is the only manmade structure large enough to be seen my astronauts in space.  It is 1,600 miles long.  How longer is the Great Barrier Reef than the Great Wall of China?

Christ the Redeemer statue looks out over the ocean in Brazil.  It is 98 feet and 5 inches tall.  How many inches is that altogether?

The Eiffel Tower is 1,065 feet tall.  How much taller is the Eiffel Tower than the statue in Brazil?

The Nile River is the longest river in the world.  It is 4258 miles long.  The Amazon River is not quite as long, at 3,983 miles, but more water flows through it than in any other river in the world.  How much longer is the Nile than the Amazon?
