Miss Cam and Nate go walking on the Great Wall of China — thirteen thousand miles of stone and earth winding across mountains, deserts, and grasslands, built a little at a time over two thousand years. Kids will find out why the Great Wall isn't actually one wall, how Ming dynasty builders glued it together with boiled sticky rice (scientists finally figured out why that works), how guards sent warnings hundreds of miles in a single day using nothing but fire and smoke, and why the famous "you can see it from space" fact is not true at all. Packed with marching, galloping, guessing, and stirring along at home, this is history made for curious kids ages 4-10. First stop in our tour of the New Seven Wonders of the World. Turn your imaginations ON!
