Drilling Paradise Dry?

Answers will vary but should include the following points:

1. The 19-million-acre Arctic National Wildlife Refuge was established in 1980 to protect a rich variety of wildlife comparable to the Serengeti Plain in Africa. It's also oil rich, and President George Bush wants to let oil companies explore and drill inside the Refuge.

2. Oil is a fossil fuel, or an energy resource derived from decayed material of dead plants and animals. Oil is used to make gasoline, heating oil, plastics, candle wax, and tires.

Tour De Lance: Cycling Physics

Answers will vary but should include the following points:

1. The peleton, French for "pack," is a beehive-like formation where riders swarm together. Drafting--or "wheel sucking"--is a team-orchestrated physics trick where riders take turns shielding each other from the wind. This allows the rider tucked behind the front runner to use less energy. Maillot jaune is the yellow jersey worn only by the Tour de France's overall leader.

2. Pasta is crammed with complex carbohydrates, chemical starches that the body converts into energy. Each minute of bike pedaling burns 17.5 calories. A peanut butter and banana sandwich is energy-rich, a good food source for pedal power.
