EXPLORE – Corn­a­Plenty, or Not Suggested Day 1 (continued) – 20 minutes

1. Ask students if they have ever noticed that some foods are scarce.

Give an example of one such as: sometimes if a certain food (like milk) is

scarce, it can cause other foods to cost more. For instance, milk is an

ingredient in ice cream, so the price of ice cream can go up. Explain to

students that they are going to research the food corn to find out if it is

abundant, or scarce. If it is abundant the price will be low, if it is scarce

the price will be high.

2. Read aloud to students the Teacher Resource: Corn Has Become Expensive.

3. Using the Internet and current events resources, students research, develop, and

record ideas about scarcity, supply and demand.

4. Guide student research of this year’s corn crops to discover:

Is corn abundant or scarce this year?

What factors affect the price of corn?

What are the products and by-products of corn?

before the students begin working on their flow

chart.

EXPLORE – Sorting Our Resources Suggested Day 2 – 20 minutes

1. Explain that some resources are renewable (can be used and recreated such as

wood) and some are not renewable (e.g., when the resource is used, it is

exhausted/consumed, like oil)

2. Students research to create a chart using the Handout: Renewable Resources

1. Choosing one renewable and one nonrenewable resource, students use arrows,

words, and shapes to create a chart explaining what they have learned about

renewable or non-renewable resources.

2. Students explain the final charts to another student.

3. The class chooses (by voting) the three best examples of charts to post in the

hallway for others to observe (or post all student work if space allows). Example

charts should be easy to understand and the best at explaining the differences of

renewable and nonrenewable resources.

TEKS: 3.7B; 3.17D; 3.18B

Scarcity Game Instructions

Object of the game: Students will experience trading and bartering for an item that is very scarce.

Supplies needed:

1 envelope per student

Tokens (printed or real) at least 10 per student The tokens can be printed, or real things that are of no real value such as paper clips, rubber bands, stickers, erasers, pencils (even used pencils), chalk, plus only one or two valuable things in only one or two of the envelopes…such as a small candy bar, or a quarter. You can even put in a penny, nickel, dime and quarter. Included are homework, water, bathroom, and front of line passes if you choose to use them. Consider using these or create other tokens that might be meaningful in your classroom.

Directions: Tell the students you are going to play a Scarcity Game. Tell students they may use the token in

their envelope to trade for tokens in other students’ envelopes that they would rather have. The other student

must agree to the trade. You must barter by trading things that you have for things that you want or need.

Explain that at the end of the game no matter what you have traded for, we will play a second time. At the end

of the second time we play the game, we will stop and find out “who has what.”

Tell the students the most scarce items in the game. (drink of water passes? Candy? Whatever you made

scarce.)

To play the Scarcity Game, the teacher gives students sets of tokens placed into envelopes. Give each student

an envelope of tokens and then set the rules for trading. The rules should be simple. The rules can be things

like: you can only trade with one person at a time, you cannot talk, or you can talk in a whisper. Also, SET A

TIME LIMIT using a timer.

Once everyone understands the rules, begin the game. Ready, set, go….and then say STOP! (After about 3-5

minutes.)

Debrief: Discuss with the students what happened in the game. Ask what happens when something is scarce?

What happened in the game when something was scarce?

Ask student to name things in real life that are scarce. (Gasoline? Water in a drought? Sometimes certain toys

at Christmas?)

Corn Has Become Expensive

Facilitate a discussion having students name products that use corn. Cereal, popcorn, bakery products, baby food, corn on the cob, corny dogs, corn syrup for sweetening drinks, candy, baked sweets, adhesive (sticky stuff), animal foods, an additive with gasoline

Read to students: It takes a great deal of water (irrigation or rain) to grow corn. More than most other

crops, corn takes lots of water to grow. When there is a drought (severe lack of rain,)

corn can be scarce that year.

Corn is needed for many things in our world. It is used as cattle feed, human food like

cereal, cornbread, corny dogs, corn syrup, corn oil, popcorn, and by-products like bath

powders, laundry starches, adhesives on stamps and envelopes, and corn starch that

keeps chewing gum from sticking to wrappers. More and more, corn is converted into a

liquid called ethanol that is combined with gasoline to make gasoline cheaper and

cleaner.

Years with droughts lead to smaller corn harvests causing corn prices to increase. Some

products using corn like sweetened drinks become more expensive until the drought is

over. When products are scarce, they become more expensive so the products they are

in become more expensive. Scarcity makes the price go up. The demand is more than

the supply. One result is that people who have money can afford to buy the higher

priced corn, so the amount of available corn is distributed to fewer people who still have

money to buy it.

Because corn during a drought is more expensive, and people want to buy corn products

(demand), if you want those products, you can expect to pay more money for products

such as popcorn at the movie theater, or beef and milk since corn feeds cattle that

produce beef and milk. Even some chickens and pigs are fed corn, and if corn is scarce

then those products will be more expensive, so fried chicken and hot dogs will cost

more money, too. The more people use these products and the more people demand

these products, the less that is available and the higher the price. As gas usage

increases, corn prices increase. The people who can afford to pay more money for corn

products will have them. Some nations that have difficulty feeding its population

Unit: 10 Lesson: 02

encounter even greater problems as corn prices rise. People may need to do without

other things so that they can eat.

Farmers who did not have a drought and who could grow lots of corn will be able to get

higher prices for their corn because the corn is scarce. People who could grow corn

during that year may make lots of money. During a rainy year, if many farmers can grow

corn, then lots of corn will be available and distributed. The price of corn will likely go

down. The supply will be closer to meeting the demand.

How can people help with the problem of scarcity when it comes to water? Research a

list of ways you can save water or use less water during a drought when rain and water are scarce.

Renewable Resources List KEY

Water as well as other products may be renewable or nonrenewable depending

on the location and rate of consumption. Carefully managed water and soil are

usually considered renewable. In the case of water, some communities remove it

from aquifers and other sources faster than it is replaced. Poor management of

water and soil in certain local areas can lead to water/soil being considered

nonrenewable.
