Some children do better in school than others for many reasons. All kids have different talents and abilities, and some of these just show up better in school. Some children may be naturally better at reading and writing, working with numbers, and at storing and using information.
Some children are very organized, good with managing their time, and diligent about doing their homework. Most schoolwork requires these skills, so kids who are strong in these areas are likely to be better students. Still, most kids have enough ability to earn the basic skills taught in schools, things that they will need to know to get along well in the world once they graduate. Kids succeed by putting a lot of time and effort into their studies, by getting help when they need it, and by not giving up!
The town meeting is one aspect of local government that still exists today, although it was created in the early years of the republic. At least once a year the registered voters of the town meet in open session to elect officers, debate local issues, and pass laws for operating a government. As a group, or body, they decide on road construction and repair, construction of public buildings and facilities (such as libraries and parks), tax rates, and the town budget.
Having existed for more than two centuries, the town meeting is often called the purest form of direct democracy because governmental power is not delegated, but rather exercised directly by the people. However, town meetings cannot be found in every area of the United States. They are mostly conducted in the small towns of New England, where the first colonies were established.
Green plants get nourishment through a chemical process called photosynthesis, Which uses sunlight, carbon dioxide, and water to make simple sugars. Those simple sugars are then changed into starches, proteins, or fats, which give a plant all the energy it needs to perform life processes and to grow. Generally, sunlight (along with carbon dioxide) enters through the surface of a plant’s leaves. The sunlight and carbon dioxide travel to special food-making cells (palisade) deeper in the leaves. Each of these cells contain a green substance called chlorophyll.
Chlorophyll gives plants their green color and traps light energy, allowing food making to take place. Also located in the middle layer of leaves are special cells that make up a plant’s “transportation” systems. Tubelike bundles of cells called xylem tissue carry water and minerals throughout a plant, from its roots to its outermost leaves. Phloem cells, on the other hand, transport the plant’s food supply sugar dissolved in water—from its manufacturing site in leaves to all other cells.
No. Denning bears, such as brown and black bears, often retire to their caves for the winter months, but they sleep lightly, and are often active, with females giving birth to cubs during the winter. They don’t technically hibernate during these months. Hibernation is when a species passes the winter in an inactive state, conserving their resources and energy until winter passes.
Bears are not true hibernators because their body temperature drops only a few degrees and they show only a moderate drop in their metabolism. Small animals with high metabolic rates such as rodents, hummingbirds, and bats are true hibernators: their body temperature drops almost to the level of the surroundings and they show little response to nature’s sights and sounds. These animals collect and eat a lot of high-calorie foods (such as nuts) to store calories to make it through the hibernation period.
The Chinese lunar calendar is based on the cycles of the Moon, and is constructed in a different fashion than the Western solar calendar. In the Chinese calendar, the beginning of the year falls somewhere between late January and early February, and contains 354 days.
Each year is given an animal designation, such as “Year of the Ox.” A total of 12 different animal names are used, and they rotate in the following sequence: Rat, Ox, Tiger, Hare (Rabbit), Dragon, Snake, Horse, Sheep (Goat), Monkey, Rooster, Dog, and Pig. The Chinese have adopted the Western calendar since 1911, but the lunar calendar is still used for festive occasions such as the Chinese New Year. Many Chinese calendars print both the solar dates and the Chinese lunar dates.
The words parkway and driveway come from the days when only the well-off could afford an automobile.
The long, winding roads from the highway to the manor were, and are still, called “driveways.” On the other hand, to ensure the pleasure of driving, highways were built carefully, with planted trees and groomed medians to imitate the natural beauty of a park, so they were called “parkways,” meaning left in an enhanced natural state.
Beginning in the Middle Ages, Boxing Day was known as St. Stephen’s Day in honour of the first Christian martyr. Although unknown in the United States, Boxing Day is still observed in Britain, Canada, New Zealand, and Australia.
It’s called “Boxing Day” because on the day after Christmas, the well-off boxed up gifts to give to their servants and tradespeople, while the churches opened their charity boxes to the poor.
According to a national survey conducted by the American Pet Products Manufaturers Association in 2008, Americans owned about 75 million dogs and 88 million cats. Approximately 39 percent of U.S. households own at least one dog, and 34 percent own at least one cat.
According to the American Kennel Club, Labrador retrievers are the most popular dog breed, followed by Yorkshire terriers, German shepherds, and golden retrievers. Persian cats are the most popular feline breed, followed by the Maine coon and the Siamese. Combined reptiles are the next popular type of pet, followed by birds and horses.
The immune system protects the human body against germs, which are microorganisms that cause sickness and disease. There are four major types of germs— harmful bacteria (pathogens), viruses, fungi, and protozoa. This defense system begins with the skin, which stops germs from getting into your blood or tissues. If germs get into your body, for example through your nose or mouth, white blood cells called phagocytes and lymphocytes attack them. Phagocytes scout out and destroy invaders, and long-living lymphocytes remember the invaders and release chemicals called antibodies to make the body resistant, or immune, to them.
White blood cells live in the bloodstream, lymphatic system, and spleen. The lymphatic system (or lymph system, for short) is a far-reaching network that extends throughout your entire body. A clear liquid called lymph runs throughout the system, washing the body’s cells with nutrients and water and detecting and removing pathogens. Lymph is filtered through the lymph nodes, and then passes into the body’s bloodstream.
Crocodilians—scaly, carnivorous reptiles that include crocodiles, alligators, caimans, and gharials—are descendents of the archosaurs who lived on Earth with the dinosaurs 200 years ago.
Today’s modern crocodiles are semi-aquatic predators that have remained relatively unchanged since the Triassic period. Besides birds, they are the dinosaurs’ closest living relatives.
