Why do women in some countries wear veils?

A veil is a piece of cloth that is usually worn to hide a person’s hair or face. Women have worn veils since ancient times—mostly in Middle Eastern countries— primarily to keep men from looking at them. Many women of the Muslim faith still wear veils of some type when they are out in public. In some Muslim countries, only a woman’s eyes are allowed to show.

Although Westerners (people from North America and Western Europe) may find these veils symbolic of women’s restricted freedoms in many Muslim societies, Muslim women wear them to honor long-held traditions of modesty and to show respect for their religion and the men in their lives.

How do police officers help the community?

There are about 800,000 police officers in the United States. Police officers protect the lives and property of citizens. They maintain order, catch lawbreakers, and work to prevent crimes. Also called “peace offers,” police officers have different responsibilities depending upon the size and structure of the communities in which they serve.

Police officers may patrol the streets on foot or in squad cars, control traffic, or work as detectives investigating crimes. At the police station, officers may be assigned to work in the crime laboratory or the records department. All officers file reports of incidents, and many testify at trials and hearings.

What is a “kissing bridge”?

Kissing bridges are covered bridges with roofs and wooden sides. They are called kissing bridges because people inside the bridge cannot be seen from the outside, making them good places to kiss discreetly. They were first built in the nineteenth century by engineers who designed coverings to protect the structures from the effects of the weather.

More than 10,000 covered bridges were built across the United States between 1805 and the early twentieth century. As of January 1980, only 893 of these covered bridges remained—231 in Pennsylvania alone, where the first one was erected.

Can my cat or dog benefit my health?

As a matter of fact, yes! Researchers believe that regular contact with pets can reduce levels of stress and reduce blood pressure (the force of blood pushing against the walls of the arteries as the heart pumps out blood).

Pets offer stability, comfort, security, affection, and intimacy. Owning a dog also provides a great opportunity to get exercise and fresh air, since it will need to go for a walk every day.

How hot is the Sun?

The Sun is extremely hot. The surface of the Sun (or its outer visible layer, called the photosphere) is about 10,000 degrees Fahrenheit (5,537 degrees Celsius)— about 50 times the temperature required to boil water.

The core of the Sun, where solar energy is created, reaches 27 million degrees Fahrenheit (15 million degrees Celsius). It is so intense that nuclear reactions take place there.

How does the metal switch in a toaster bend?

It bends because it is made of two metals that are joined together, something called a bimetal switch. One metal (usually brass) expands quickly when heated, while the other expands much more slowly. This difference causes the switch to bend toward the low-expansion metal.

Bimetal switches are used in other appliances that switch electricity on and off to keep their temperatures even, like irons and refrigerators. The thermostat that regulates the temperature of your home by turning your furnace and air conditioner on and off also uses a bimetal switch.

Which muscles are the largest, and which ones are the smallest?

The largest muscle is the buttock muscle (gluteus maximus), which moves the thighbone away from the body and straightens out the hip joint. It is also one of the stronger muscles in the body. The smallest muscle is the stapedius, in the middle ear.

It is thinner than a thread and 0.05 inches (0.127 centimeters) in length. It activates the stirrup that sends vibrations from the eardrum to the inner ear. The longest muscle is the sartorius, which runs from the waist to the knee. Its purpose is to flex the hip and knee.

What can parents do to help kids with their library assignments?

Very often school-age children will ask their parents for help with library assignments. And very often parents will find themselves gradually taking over and doing a report for their son or daughter. Instead, ask your parents to try the following ideas to motivate you and increase confidence in wading through a book report or library assignment (courtesy of Reading Rockets, a nonprofit educational service of WETA, Washington, D.C.’s leading public broadcasting station): • Ask your children questions about the assignment and encourage them to ask their teacher questions. This helps children to clarify what they are trying to do. Help them to identify smaller components of the topic they are researching or to see the topic as part of a larger topic. (For example, brontosaurus is a subgroup of dinosaurs, which is a subgroup of extinct animals.) These classifications will help them to identify useful references. • Suggest that they look up the topic in the library catalog, periodical guides, and reference books. The librarian will direct them and help them get started.

Be sure they know how to use a table of contents and index. Suggest they start with something general about the subject and be prepared to consult more than one source. • Help them to break assignments into logical segments and avoid last-minute panics by setting deadlines for each phase of the work. Allow them plenty of time to gather the materials they need. • Help them to determine if the community library has the resources they need or if they need to check other information sources. • Encourage your kids to ask the librarian for help in locating materials and let them do their own talking. • Give them encouragement, advice, and a ride if they need it, but resist the temptation to take over an assignment. Let your children assume responsibility for researching and writing reports. It is the best way for them to library skills that they will able to use for the rest of their lives.

What was the Challenger disaster?

Seven astronauts were aboard Challenger flight STS-51L when it exploded during liftoff on January 28, 1986. Christa McAuliffe was a Concord, New Hampshire, high school social studies teacher. She and the other six crew members were killed when a solid-fuel booster rocket leak led to a massive fuel tank explosion during liftoff from its launch pad.

NASA’s next flight was Discovery, which was launched on September 28, 1988. After the Challenger disaster, NASA’s three remaining shuttles— Atlantis, Discovery, and Columbia—were rebuilt, each with more than 250 modifications improving safety and performance.
