Chapter 5: Pluto is not a Planet

Read the passage. Then answer questions about the passage below.

 


Proyecto Salón Hogar

 

 

 

  Many people are saying that Pluto is no longer a planet. Are they right? Is Pluto no longer a planet? There's debate in the scientific world about this issue.  

   National Geographic News says that, according to the International Astronomical Union, a full-fledged planet is an object that orbits the sun and is large enough to have become round due to the force of its own gravity.      

    Because Pluto doesn't meet these standards, the IAU classifies Pluto as a dwarf planet. Not everyone agrees that this is a good way to decide, though. Andy Cheng, is a planetary scientist at Johns Hopkins University.

   He says that the new rules aren't clear enough and asks the question "how round is round? ...I'll still continue to maintain that Pluto is a planet," he said.

   Owen Gingerich is an astronomer and historian at Harvard University in Cambridge, Massachusetts, and head of the IAU committee proposing the definition. He favored a special distinction for Pluto.

   Gingerich supported a proposal to call the big eight planets classical planets—as opposed to just plain "planets"—and Pluto and the others dwarf planets, so there would be two classes of planets.

   He believes that reclassifying Pluto as a dwarf planet is not "sensitive to the historical and cultural role that Pluto has played." The argument continues.

   In the meantime, however, many people are correct—new textbooks will list Pluto as being a dwarf planet.

   What do you think it is?

Clocks

 

 Clocks are used to measure time. Clocks are used to show the time. Clocks are used so that people can agree on the time.

   People use clocks to measure units of time that are shorter than natural units. Natural units are the day, the month, and the year. The sun rises at the beginning of each day.

   The moon is new at the beginning of each month. The sun appears at the same place in the sky at the beginning of each year. The clock is a very old invention. Sundials were used in ancient times.

   Sundials work by measuring shadows that are cast by the sun. Candle clocks were used a very long time ago. Candle clocks work by measuring the time it takes for the wax to melt.   

   Hourglasses are similar to candle clocks because they also measure the time it takes for something to happen. Hourglasses work by measuring the time it takes for sand to pour through a small opening into a glass.

   Mechanical clocks appeared in the 13th century in Europe. They work with a system of moving gears. The gears always move at the same speed. Pendulum clocks work with a swinging weight.

    The swinging weight is called a pendulum. The pendulum makes the clock parts move. Now people typically use mechanical clocks or digital clocks. Digital clocks show numbers on a screen.

   The numbers represent the time. Some people use auditory clocks. Auditory clocks use language to tell the time aloud.

   Computers also use clocks. Computers use internal clocks in order to work properly. In today’s world, clocks are every-where –– in homes, schools, offices, and public places. Many people live their lives according to the clock.

   People go to work and return home according to the clock. School days start and end according to the clock. Airplanes take off and land according to the clock. It is fun to imagine a world without clocks!

Literature: The Conflict of a Story

 

   The term conflict refers to the events that result from the struggle between two opposing forces in a story. In most stories, the main character is involved in this struggle.

 

Typically, there are four kinds of conflicts:

   -The main character struggles against another person.

   -The main character struggles against nature.

   -The main character struggles with society.

   -The main character struggles with him or herself.

    

   Example: He is struggling against a group of people (society).

                     Ralph is deciding whether to work with Charles or not.

                     Since it is a decision he has to make alone, he is struggling with himself.

 

 

There are two additional categories of conflicts:

 

An internal conflict is a struggle that takes place in a character's mind.

 

An external conflict is a struggle between a character and an outside force.

Classify the conflicts below, according to the four basic kinds of conflicts.

 

Write IC if the conflict is internal or EC if it is external.          

   1. A child wants to go out and play, but he has to study.                         ___

   2. A man is struggling to walk home against the fierce winds.               ___

   3. A community is struggling with the government to prevent floods.     ___

   4. A little boy cries because he is afraid of the dark.                               ___

 

 

Literature: The Plot of a Story

 

 

 

   1. Rising Action: Two boys ride to school on their bikes.

   2. Conflict: It is raining cats and dogs! They can hardly see where they're going.

   3. Climax: A car drives by at an excessive speed. The boys and the car crash!

   4. Falling Action: The boys lie on the street crying. They have not been harmed.

   5. Resolution: The boys decide to never ever ride their bikes in stormy weather again.

Most stories revolve around a storyline, which is called the plot.

The plot is composed of the order in which the main events of a story take place.

The plot forms the backbone of a story, play, or narrative poem.

 

The following elements are part of every plot: 

   The rising action, or exposition, includes the introduction of the characters, and setting.

   The conflict of the story presents the main struggle of the characters in the story.

   The climax, or turning point, is the highest point of suspense in the story.

 

This point in the story determines the conclusion, or outcome, of the story.

   The falling action presents the consequences of the turning point.

   The resolution, or outcome, of the story is the conclusion, or ending.

 

At this point, the tension in the story may have disappeared, the characters may have changed, or the conflict may have been solved. Think of an adventure for Ralph and Charley. Write down the plot in five sentences that describe the rising action, conflict, climax, falling action, and resolution.

 

   1. Rising action: _____________________________________________________________________________

   __________________________________________________________________________________________

   2. Conflict:  _________________________________________________________________________________   

   __________________________________________________________________________________________

   3. Climax:   _________________________________________________________________________________

   __________________________________________________________________________________________

   4. Falling action: _____________________________________________________________________________

   __________________________________________________________________________________________

   5. Resolution: _______________________________________________________________________________
