as for is the earth round or flat. here's an idea.
get a buddy. go to homedepot. buy two twelve foot long dowels. you stay put with one poll. have your buddy drive 60 miles down the road with the other poll. making sure both of your poles are plum and standing on level ground measure the length of the shadows at exactly 3 pm. if the earth is flat the shadows will be the same length.
