Readers’ Theater

A Family Gathering

SETTING: Gathering of the Johnson, Kwan, and Ortiz families

CHARACTERS: Grandfather Ortiz, Lin Kwan, Teresa Ortiz, Gary Johnson

Grandfather Ortiz: Children, it’s so good to see you again. It’s nice to have a meal together

but I haven’t heard about school this year. Tell me, how do you like it so far?

Lin: It’s great! I’m trying out for the baseball team later this year.

Teresa: It’s OK, I guess. I’m not crazy about my history class, but English and math are

good.

Gary: I like most of my classes, but I’m kind of worried about science. I love studying about

the body, plants, and animals, but this year we have to learn about the periodic table. I took

one look at it in the back of my science book and thought I was looking at something in a

language that I don’t understand! How are you supposed to keep track of what’s a metal

and what’s a nonmetal?

Lin: I know what you mean. When Mr. Mendoza started talking about groups, periods, and

properties, he lost me.

Teresa: I understood those things, but all that talk about lanthanide and actinide, confused

me. I was completely mixed up when he finished with that.

Grandfather Ortiz: Children, slow down a minute. Let me try to help. Whenever I’m

confused about something, I try to think about it in terms of something I understand.

Lin, Teresa, and Gary: Like what?

Grandfather Ortiz: Think about it like this. Did you notice all the beautiful place cards on

the table today? Tell me, what was printed on them?

Gary: Our names. Mine said “Gary Johnson.”

Teresa: And mine said “Teresa Ortiz,” and Lin’s said “Lin Kwan.”

Grandfather Ortiz: That’s right. Your first names are different from each other and usually

from others in your family. First names usually don’t tell anything about your family as a

group. But your last name is your family name. Other family members also share the same

last name. These family members might share the same address, the same house, and

maybe even the same hair or eye color.

Lin: I get it! So in the periodic table, the periods or rows of the table are like our first

names. They don’t really have anything in common.

The Periodic Table 51

Name Date Class

Reader’s Theater continued

Teresa: And the groups, or columns of the table, are like our family names. The members

of a group share similar chemical and physical properties.

Gary: This is beginning to make sense. And I think I see how the lanthanide and actinide

series fit in. Just like there wasn’t room at the table for everyone to sit and we had to set up

some smaller tables, the lanthanide and actinide series are just sitting at the bottom of the

table to save space.

Grandfather Ortiz: That’s correct, Gary. The periodic table would be really wide if they put

rows six and seven where they belong. Let’s see if you can help each other with the three

regions of the periodic table. Teresa, you go first.

Teresa: OK. What region contains elements that have luster, are malleable, ductile, and are

good conductors of electricity?

Lin: I know. It’s the metals. They’re used to make things like aluminum foil, cars,

machinery, and jewelry. In the periodic table, they’re on the left side. Now it’s my turn to

ask a question. What region has elements that are brittle, have no luster, and aren’t very

good conductors of electricity?

Gary: That’s easy. Those are the nonmetals. They’re used to make plastics and lasers and are

in all plants and animals and even in the air we breathe. They’re on the right side of the

periodic table. Teresa, it’s your turn to answer. What region contains elements that have

properties of metals and nonmetals?

Grandfather Ortiz: Hold on there, Gary. First I want to ask you a question. Can you tell me

something about a special group of nonmetals, the noble gases?

Gary: Are they the kings and queens of the periodic table?

Lin: Very funny, Gary. The noble gases are gases that are stable, so they don’t exist naturally

in compounds. They’re elements like helium, xenon, and krypton.

Teresa: Hey you guys, it’s my turn. The answer to your question, Gary, is the metalloids.

They conduct electricity at high temperatures, but not at low temperatures. Where would

we be without a metalloid like silicon for our computer chips?

Gary: Thanks Señor Ortiz, this has really helped. I’m not worried about the periodic table

anymore.

Grandfather Ortiz: I think I hear the call for dessert. Is everyone ready?

Lin, Teresa, Gary: Let’s go!

Nonmetals and Metalloids

Directions: Use your textbook to answer each question.

1. Nonmetals are the elements on the periodic table that have no metallic

properties.

Many homebuilders use cellulose to insulate attics and walls. The insulation helps

homes stay cool in summer and warm in winter. Cellulose is a plant fiber largely made

of carbon. Based on the properties of cellulose, would you expect carbon to be a metal,

a nonmetal, or a metalloid? Why?

2. Groups 14, 15, and 16 on the periodic table contain metals, nonmetals, and

metalloids.

How are the elements in these groups alike? How are they different?

3. Electronics manufacturers use metalloids such as silicon in their products.

Why do you think manufacturers use metalloids instead of metals for some electronic

devices?

Enrichment LESSON 3

Radon

You can’t see radon, and you can’t smell

it or taste it, but it is present in all areas of

the United States, as shown on the map.

Where is radon?

Radon is a gas produced by the

radioactive decay of the element radium.

Radioactive decay is a spontaneous process

in which an atom of one element decays or

breaks down to form another element by

losing atomic particles (protons, neutrons,

and electrons).

Radon is present throughout the United

States. It enters the air from the natural

radioactive breakdown of uranium in soil,

rock, and water.

Radon travels shorter distances in wet

soils than in dry soils before it decays. It

can get into any type of building—homes,

offices, and schools—and can produce high

indoor radon levels. The gas typically

moves through the ground to the air above

and into homes through cracks and other

holes in the foundations. The buildings

trap radon inside, where it can build up.

About one out of every 15 U.S. homes is

estimated to have elevated radon levels.

Why is radon a problem?

Levels of radioactivity are commonly

measured in picocuries (pCi), a unit of

measure named to honor Marie Curie, the

physicist who discovered radium. A 115 m2

house that has 4 pCi of radon per liter of

air (4 pCi/L) has about 2 million radon

atoms decaying in it every minute. The

Environmental Protection Agency (EPA)

estimates that high levels of radon cause

about 21,000 deaths per year.

The EPA recommends that

• all homes should be tested for radon

because it’s easy and inexpensive;

• homes should be treated if the radon

level is 4 pCi/L or higher;

• radon levels less than 4 pCi/L should

also be reduced, because they might

increase the risk of cancer.

Applying Critical-Thinking Skills

Directions: Respond to each statement.

1. Study the map. Identify the largest areas of low radon potential.

2. Hypothesize about why those areas have a low radon potential compared to the areas

of high potential.

3. Evaluate whether the third EPA recommendation is helpful, in light of the other two.

Challenge LESSON 3

Radon Information Campaign

All citizens should know about the properties, effects, and incidence of radon and about

methods for detecting and protecting themselves from indoor radon.

Develop a plan for a three-year nationwide radon information campaign that will inform

citizens of the radon problem and how to alleviate it. Use reference materials such as U.S.

and state radon maps that are available from the U.S. Geological Survey and the EPA.

Include the following in your plan for the campaign:

• a list of information sources

• a project time line

• a description of the target populations for years 1, 2, and 3

• samples of informational materials to be developed

• what to tell the citizen populations

• how to reach citizens

• how to determine the success of the campaign
