Name: edHelper Principles of Relative-Age Dating

Have you ever heard the phrase "older than dirt"? Can anything be older than dirt? The answer is yes! Dirt is formed as layers of rock are eroded away. Some layers of rock are older than others. A process called relative-age dating helps scientists determine how old these rock layers are. This has also helped them to know how old the Earth is.

Relative-age dating helps scientists put Earth's historic events in order. They compare one event or rock layer to another. There are many principles that help scientists with this process.

One principle is called original horizontality. This simply means that sediments are usually deposited in horizontal layers. As the layers build up, they cement together to form sedimentary rocks.

While looking at rock layers, scientists can use another principle to help determine relative age. This is called the law of superposition. This law assumes that each layer of sediments has been deposited at a different time. Layers on the bottom are deposited first. The younger layers are on the top. This principle only works, of course, for sedimentary rocks that have not been disturbed.

A principle that helps scientists determine relative ages of disturbed rock layers is called cross-cutting relationships. This rule is used with igneous intrusion, when there is a fault. A fault is a crack in a rock layer. Movement takes place at a fault. This rule states that a fault is younger than the rock it cuts across. For example, scientists may discover a layer of schist. In a certain area, a layer of granite cuts across it along a fault. The principle of cross-cutting relationships helps scientists to know that the granite is younger than the schist. The granite has intruded into the schist.

Erosion can make relative dating difficult. There is a geological principle that helps scientists with these problems, however. When a layer of rock is eroded, some of the particles are carried away. The loose material on the surface may mix with the new layer deposited on top. This is called an inclusion. Scientists must learn to identify inclusions and then focus on the rock layer on the bottom, knowing that it is older than the one on top.

Another way to determine relative age is by correlation. This is a way for scientists to match rock layers that are found far from each other. Geologists carefully examine the rocks. They look for unique fossils and other features. This helps them compare the layers.

The process of relative-age dating is based on the idea that sediments have been deposited in the same way since the beginning of time. Imagine standing on the bank of a river. The water flows by, depositing sediments along the bottom. This process has always happened the same way. This is called the principle of uniformitarianism. Name: edHelper Scientists once used this principle as a means to determine the age of the Earth. However, other methods have since proved to be much more accurate. Even though this principle cannot be used to determine the age of objects, scientists still use relative-age dating to compare rock layers. They can tell if one rock layer is older or younger than another. The relative age of something is not exact. Scientists use other methods if they need to know the exact age of a rock.

Where and when was pizza first made? Experts cannot seem to agree on an exact place and time. They do agree that pizza was not first made in the . Pizza appeared in the U.S. in the late nineteenth century. Italian immigrants began selling it in their neighborhoods in large cities. In Chicago, a pizza maker would walk up and down the streets. He would carry pizzas in a large metal washtub on his head. Experts say that was the way that pizzas were sold in Naples, Italy. Pizzas then began to appear in grocery stores and small cafes.

Gennaro Lombardi is given credit for having the first official pizzeria in the U.S. It was in New York City. Lombardi's business began as a grocery store in 1897. He then opened a pizzeria in 1905. A whole pizza could be bought for five cents. Many people could not afford that. Instead, they were asked what they could afford. They were given slices according to that amount. Many pizzerias have opened over the years. Home delivery has become popular. Pizza is a favorite food of many.

It was nearly two years until the election, but already the wheels were in motion to start the process of electing the next President of the United States. Since the current sitting president, George Bush, had already served two terms, he was not eligible to run again. His vice president, , chose not to run. This meant that it would be a wide open contest. No one had a clear advantage. Anyone could win.

There were plenty of politicians who were interested in the job. Many names were suggested, and many hopeful candidates considered their prospects.

Soon the Democratic Party had a large field of candidates, many of them current U.S. senators. There was , , , , , , and .

The Republican Party had many candidates, too, including , , John McCain, Duncan Hunter, , , , , and Tommy Thompson.

Smaller parties, like the Green Party, fielded their own candidates. , who had run in several earlier presidential elections, chose to run as an Independent.

Some other names were frequently suggested as possibilities including civil rights leader Al Sharpton and former vice president , who had become popular for his environmental activism, but neither of these men chose to enter the race.

The candidates who did decide to enter the race had to work fast. They needed to gain as much popular support as they could and as fast as they could. They needed to mobilize volunteers and paid campaign workers and organize their campaigns. They also needed to raise money-- lots of money.

Some candidates started out with a slight advantage. New York Mayor Rudy Giuliani, a popular figure ever since 9/11, was an early favorite. Hillary Clinton was already well-known from her days as First Lady during her husband 's presidency. John McCain was a popular leader and war veteran who was well known for his sacrifices for the country as a prisoner of war. Barack Obama had caught the attention of the American people when he spoke at the 2004 Democratic Convention.

Each candidate worked with his or her team of supporters to plan campaign strategies that would surpass the strategies of the other candidates. Meanwhile, the American people watched the contest and began to take sides. Name: edHelper Some candidates had more success than others.

By the end of 2007, the field of candidates was narrowing down. The Democrats had three top runners - Hillary Clinton, Barack Obama, and John Edwards. The three top candidates for the Republicans were Mike Huckabee, Mitt Romney, and John McCain.

In the beginning of 2008, states began to hold their primary elections. By February it was clear that it would be either Clinton or Obama for the Democrats versus Huckabee or McCain for the Republicans. Everyone looked to February 5, known as Super Tuesday because many states held their primary elections on that date.

But by the end of that day, it was still unclear who the two final candidates would be. Sometimes one candidate would be in the lead, sometimes another. Still, it was getting closer to the moment when each party would have its one official candidate.

For the Republicans, that moment came in March when Mike Huckabee conceded to John McCain. For the Democrats, the battle continued until June when finally it became clear that Barack Obama was the leading candidate.

Obama and McCain had already been campaigning for over a year, but the real contest was just beginning. Right up until Election Day, November 4, 2008, they would continue to compete with debates, advertisements, and rallies to be the voters' choice for their new president.

Everyday we make judgments based on our observations. Your friend's dog may not like you because every time you go to pet the dog it growls. When your teacher hands back your geography test, he smiles which makes you think that you did very well. When you step outside in the morning, you notice it is very cloudy. You have a feeling it will rain, so you decide to carry your umbrella in your backpack. You have used two very important science process skills used by all scientists. These skills are called inferring and predicting.

When scientists infer, they draw conclusions, interpret, and try to explain their observations. For example, if a scientist observes that Plant A has a higher rate of growth when it is placed on the counter than when it is on the window sill, the scientist might infer that this plant grows better in the shade than in the sun. Inferences can also be made from recorded data. One example would be when students examine results from an experiment on bounce height of three different types of balls. Students would examine the bounce height of ping-pong balls, marbles, and rubber balls. Based on the data, students could explain whether the height at which the balls were dropped would affect the height the ball would bounce. Scientists also make inferences from data that is received indirectly. There are many places scientists cannot visit due to safety or lack of access. When scientists study volcanoes, they use evidence from the area surrounding the volcano to make inferences about the qualities of materials inside the volcano. This type of inferential thinking also leads to another science process skill called prediction.

Inferring about scientific data also leads to predicting. Scientists use current observations about events to help forecast or make generalizations about future events. These predictions usually follow after numerous testing situations and observations based on these situations. An example would be when scientists study the migration habits of Canadian geese. After observing year after year how gaggles of geese invade your town's beautiful park, scientists may be able to predict the time of year the gaggles arrive and when they will depart. They may also predict if the numbers of geese within these gaggles will increase or decrease based on environmental conditions. Two other parts of predicting are interpolating and extrapolating. When scientists interpolate, they take observation data and make predictions within the range of the present data. For example, if you collected data on the growth rate of plants in five inch, eight inch, and ten inch wide pots, you could use this data to make a prediction about plant growth in a seven inch pot. If you wanted to extrapolate this data, you might try to predict the growth rate of plants in twenty or thirty inch pots. When you extrapolate data, you use current collected data to make predictions about amounts outside of that range of data. Remember, predicting is not absolute or the answer to scientific questions. It is one of the processes, along with inferring, that helps scientists to make sense of scientific mysteries. Name: edHelper Infer or Not To Infer Questions

Life can be messy, and accidents happen all the time. It's easy to get stains on your clothes. It isn't always easy to get those stains out. There are some things you can do to save your favorite clothes.

One of the best tips to get rid of any stain is to take care of it right away. If you can, wash the stained item right after the stain happens. Check the stain before you put the clothing in the dryer. If the stain didn't come out, wash it again.

A lot of people get gum on their clothes. It's easy to do. People don't always throw their gum in the garbage. They leave it in places where people can step in it or even sit in it. If you get gum on your clothes, you should be able to get it out. The first thing you want to do is get the gum really cold. Take an ice cube and hold it over the gum until it is almost frozen. Then take a knife and scrape as much of the gum off the clothing as you can. Rub dish soap or liquid laundry detergent into the cloth where the gum was. Then wash the item in hot water. If that doesn't get the gum out, treat the spot with a stain remover. You may have to wash the clothing two or three times to get rid of the stain completely.

It is also easy to get ink on your clothes. Hairspray works well to get rid of ink. Spray it on the stain, and then use a tissue to soak up the dissolved ink. Use more hairspray and a clean tissue until all the ink has dissolved. Rinse the spot with cold water. Then throw the clothing in the wash. Hot water works best on most kinds of stains. Some types of fabrics shouldn't be washed in hot water, though. Read the label on the clothing to see what water temperature should be used.

Blood is also something that can get on clothing. It can be hard to get out, but try this tip. Put hydrogen peroxide on the spot and then soak the item in cold water for ten minutes. If you still see a stain, use more peroxide. After a few minutes, rinse it with cold water. Rub some dish soap or detergent on the spot, and then put the item into the washer and wash as usual. Always use cold water for blood stains.

Grass stains on the knees of pants seem to happen quite a bit. For grass stains, treat the stain as soon as you can. Soak the pants in warm water with some laundry detergent for thirty minutes. Then treat the stain with a stain stick or liquid stain remover or make a paste of baking soda and water and put it on the stain. Then put the pants into the washing machine and wash as usual. If you can't get the stain out, use the pants for playing outside. Then it won't matter if they get more grass stains on the knees.

Following these tips will help you get some stains out. Others will never go away. Just do the best that you can. If some clothes are ruined, you can use them when working around the house or in your yard. Then you won't have to Name: edHelper worry so much about any new stains that you happen to get.

COMIC-E

? can't So, you want to think like a scientist . Well, you cant buy scientific thinking . at the "Science Market ". However, everyone has the ability to think like scientists.

All it takes is practice and the COMIC-E. What is the COMIC-E? It is a mnemonic

device for the seven science process skills we use when we take on the role of

scientists. These skills are classifying, observing, measuring, inferring and predicting, communicating, and

experimenting.

Classifying happens when you put objects and events into groups based on certain properties. The most

common properties for classifying are shape, size, and color. However, there are many different ways to classify

objects and events. For example, you can classify animals into group such as mammals, amphibians, and reptiles.

You could also take some of those animals and classify them into groups titled "Mammals on Land" and

"Mammals In Water". Classifying and observing are great partners in science. Without observation, classification

becomes tough.

You have been observing your environment since you were a baby. Every time you used your senses to

explore, you were making observations about your environment. When you use your senses, you identify objects

and events based on their properties, notice changes in objects and events, and state differences and similarities of

object and events. Your senses help you to "make sense" of your world. Name: edHelper

When you think of measuring, you often think of math. Measuring also happens in science to compare

Objects and events. Scientists use time to measure how long it takes for a liquid to boil. They also usi temperature as a way to measure how hot the water becomes when boiled. Scientists measure lengths, volumes, and other dimensions. Standard tools and familiar objects can be used to measure or Find quantity. Just think, when you were counting how many steps it took to get up the stairs, you were measuring like a scientist.

Inferring and predicting are partners when it comes to scientific thinking. when you infer, you interpret or explain what you have observed. For example, you reach out to pet your friends' cat Fluffy, but she runs away.

You begin to feel sad because you think Fluffy does not like you. Your observation helped you to infer the reason for Fluffys reaction to you. Prediction happens when you try to say what will happen in the future by using your past observations. Maybe you have tried to pet Fluffy many times before, and she has run away each time. You may now hypothesize or question why Fluffy runs away from you. This may cause you to try again. You may also predict that if you try again, she will run away. Inferring and predicting is a huge part of what scientists do to solve scientific puzzles.

Communicating happens when scientists present the data or information they have learned. Scientists use charts, diagrams, models, and writing to share their observations. They also define words, describe objects or event, and record data to keep track of their work. It was the communication in Thomas Edisons' lab journals and his models that helped to show the world his light bulb.

Finally, we get to the skill of experimenting or the doing part of science. When scientists experiment, they change objects and events and compare them to the original objects and events. For example, if you were a "milk" Name: edHelper scientist, you may woont to see what happens if you leave the milk on the kitchen counter. After a certain amount of time, you can observe how that milk compares to milk left in the refrigerator. When you experiment, you must have a hypothesis or an idea to test. You must also compare objects or events that are changed with matching objicts or events that are unchanged. This is called controlling variables. You would then need to design a procedure or series of steps to test your hypothesis. Scientists may use all or some of the other six science process skills when they experiment.

At this point, you probable realize you have had the COMIC-E all of your life. Therefore, you have always been a scientist.

When you have a bologna sandwich, what do you put on it? How about on a hot dog or a hamburger? If you lived 200 years ago, you probably would have said mustard, mustard, mustard!

You may dislike it if you find the taste of mustard too zippy, but people throughout history might disagree with your opinion. Long before ketchup was ever thought of, mustard was in common use. It was appreciated not only for its taste but also for its medicinal qualities.

Mustard seed has a long history of use in the East and Middle East. The hot feeling you get from mustard in your mouth has the same action on the skin. It increases the circulation of blood wherever it is applied as a plaster. Do you remember the rhyme about Jack and Jill? The second verse tells of Jack putting a mustard plaster on his injured head. Even now, some people use it to get rid of a chest cold faster.

Mustard is also used to improve appetite and digestion. If you have a stuffy nose, you could use mustard powder to help clear it out. Some people say that it works as well as the medicines you get from the drug store.

The Romans learned about mustard from the Greeks. It was not as popular with them as it was later in Europe, because the Romans had a wide selection of spices and seasonings. After conquering Gaul (France), the Romans began planting mustard seed there. Since it grew especially well in cooler climates, it became a favored plant not only with the Romans but with the conquered Gauls as well.

During the Middle Ages, French monasteries began to grow mustard on a large scale. They did not just grow it to sell the seed. They made it into the mustard sauces that we are familiar with today. Those sauces were sold in towns and cities in the area.

Mustard sauce was prepared by soaking the seeds overnight in water or vinegar. The next morning, they were dried in an oven. Once dried, the seeds were ground or crushed, and the hulls were (usually) sifted out. The mustard powder could then be mixed with some kind of liquid - water or vinegar - and other seasonings to get the desired mustard sauce.

The humble mustard seed has many benefits for those who eat it. It is low in calories when prepared simply. It rarely causes an allergic reaction and contains high amounts of protein.

The seeds are not the only valuable part of the plant. If you live in the United States, you might have eaten mustard greens as part of your New Year's dinner. Name: edHelper
