              Money is what you use to buy things. You may earn money from completing household chores, getting good grades, for your allowance, or for losing a tooth! Money is very important in our world and comes in many different forms.

              People have been using money for hundreds of years. Before money gave specific values for things, people simply traded items. In the United States, we use the dollar as our currency or money, but people in different parts of the world use different currencies, though some countries also use or accept our dollars.

               People earn money from the jobs they work and use that money to save for the future, pay for their houses, cars, food, taxes, medical needs and household items among other things. Even things such as turning the lights on, using the air conditioning or heat, and connecting to the internet cost money.

The Bald Eagle

The Bald Eagle is a majestic bird. The adult bird has a brown body, brown wings, white head, and large, hooked yellow bill. Younger birds appear all brown.

Bald Eagles almost always live near water because their main food source is fish. Sometimes, however, Bald Eagles will eat dead animals (carrion). They will even steal food from other birds such as ospreys and gulls! It was for this reason that the famous Patriot Benjamin Franklin preferred the Wild Turkey as America's National symbol. Nevertheless, the Bald Eagle remains America's symbol.

               The Great White Shark is the largest predatory shark, and is probably the most well-known and feared shark. The Great White Shark is gray or bluish above and white below. The largest Great Whites can reach lengths of 22 feet and weigh up to 5,000 pounds. Most are between 13 and 16 feet and weigh 1,500-2,400 pounds.

          The Great White has massive teeth, which are positioned in rows and serrated. When the Great White attacks, it bites its prey and shakes it head back and forth. The serrated teeth act as a saw and literally tear the victim apart. The Great White Shark often swallows many of its own teeth in an attack.

          The Great White Shark normally feeds on fish, seals, dolphins, porpoises, otters, and turtles. It is thought to locate its prey by electrosense and by smell. Like all sharks, Great Whites have special pores called Ampullae of Lorenzini, which enable them to detect the electromagnetic fields radiated by moving organisms. Great Whites can detect voltage as small as one half billionth of a volt.

The Tyrannosaurus Rex

The Tyrannosaurus Rex, also known as T-Rex, was one of the largest land predators to have ever lived. The T-rex could grow to 40 feet in length (a little longer than a school bus) and could stand 13 feet tall at the hips (about three feet taller than a basketball hoop). It lived in what is now western North America and may have even been partly covered in feathers.

                The Tyrannosaurus Rex was a fearsome predator with strong jaws and up to 60 teeth. Some of these teeth could grow to be almost a foot long. The T-Rex was a strict carnivore (meat-eater) and hunted other dinosaurs. Scientists aren’t sure how fast the T-Rex could run, or, even if it could run at all.

                In 1990, a fossil hunter found the most complete skeleton of a Tyrannosaurus Rex ever found! It was sold to a museum for $8 million dollars, the highest amount ever paid for dinosaur fossils.
