LO 2 Main Idea

1. Compared with the fourteen-thousand-foot peaks of the Rockies, Mt. Washington in New Hampshire may seem relatively small at 6, 288 feet high. However, the top of Mt. Washington has unbelievably treacherous weather can change from a sunny to a stormy day-- often with fierce gales. No wonder the building on this mountain top is chained to the ground.

2. Many fighters for women’s equality say it’s about time the United states put a woman’s portrait on some of its paper money. Few people know, however, that two women have already achieved that honor, a century ago. Martha Washington’s face graced a one-dollar bill and Pocahontas’’ picture appeared on a twenty-dollar bank note.

3. Trees use and give off a surprising amount of water. The water is taken in by the roots and released by the leaves. It has been estimated that eighty gallons of water a day may evaporate from the average tree. A white oak tree will give off 150 gallons of moisture in a single day during hot weather. A large oak tree will give off 28,000 gallons of water during one growing season.

5. The mystery of how salmon can find their way back to their home rivers is solved. A salmon navigates by sun and stars when traveling in the ocean. When the salmon nears the general area of the river in which it was born, it used its nove. The salmon can remember the small of the home river that it left as a baby.
