### Cross-Curricular Project Unit 3

 Lions, Tigers, and Bears, Oh My!

Introduction
Are you ready to join a team of animal experts? As part of your application to be the zoo's new coordinator, you must complete several challenging tasks. You'll make decisions about what animals to purchase for the zoo based on financial information provided to you. You'll gather specific data about the animals you choose, including their weight and expected lifespan. Finally, you'll present your findings to the hiring committee. So pack up your gear and don't forget your algebra tool kit. This adventure is going to be wild!

As you begin to go through the hiring process, we have briefly described each challenge that lies before you. The
Process section has a detailed description of each challenge. Also, the Guidance section has some helpful hints, and the Resource section has useful Web sites for you to use. So what are you waiting for? Let’s get started!

Zoo Challenge 1:
First, read a letter from the zoo Animals Inc. The letter is found in the Process section. Then, create a spreadsheet according to the request of the zoo.

Zoo Challenge 2:
Next, research the average weight, lifespan, and gestation and/or incubation period of each animal in your newly created zoo.

Zoo Challenge 3:
Last, create a presentation that explains why you chose each particular animal for the new zoo. You will give this presentation to your classmates, the board members of Animals Inc.

Zoo Challenge 1:
For your first challenge, Animals Inc. wants you to choose the animals you think should be in their zoo. First, you need to read the letter Animals Inc. sent to you. Within this letter, you will find all of the information you will need to construct your zoo.

Dear Applicant,

Hello. First, we would like to thank you for applying for the Zoo Coordinator position at Animals Inc. As part of your application process, we have created a challenge that we want you to tackle. Below is a description of the task.

Animals Inc. has \$1,000,000 to purchase animals for their new zoo. The animals you are allowed to purchase and their prices are listed below. You must be within \$1,000 of the \$1,000,000, and you must purchase at least 10 different animals. When purchasing an animal keep in mind the following:

• the gender of the animal (do you want all males, all females, or an even balance?);
• the number of each type of animal you would like to purchase; and
 Animal Price Animal Price Alligator \$14,000 Leopard \$30,000 Bearded Dragon \$9,550 Lion \$20,000 Boa Constrictor \$1,750 Manatee \$17,500 Camel \$17,000 Monkey \$5,000 Cheetah \$23,500 Panda Bear \$50,000 Crane \$8,550 Polar Bear \$32,500 Crocodile \$14,000 Pronghorn \$6,000 Elephant \$25,000 Python \$1,500 Emu \$11,500 Rabbit \$25 Giraffe \$18,500 Rhinoceros \$30,000 Goat \$125 Sea Lion \$22,500 Goose \$50 Snapping Turtle \$375 Grizzly Bear \$15,000 Tiger \$27,500 Guanaco \$6,550 Tortoise \$850 Hippopotamus \$25,000 Yak \$3,500 Iguana \$750 Zebra \$15,000

Next, write an expression for each type of animal purchased that represents the total amount of dollars spent purchasing that animal.

Good luck, be creative, but most of all, have fun!

With Sincere Gratitude,
Animals Inc. Hiring Staff

Zoo Challenge 2:
Once you have chosen the animals you want to purchase for your zoo, you will need to:

1. Use the Internet to research the average weight, the average lifespan, and the average gestation and/or incubation period for each chosen animal.
2. Create one chart that displays all of your collected data. Your chart should include the following:
• the name of each animal;
• the average weight of each animal;
• the average lifespan of each animal; and
• the average gestation and/or incubation period of each animal.
3. Create a frequency table for the average weight, the average life span, and the average gestation and/or incubation period. You will have a total of 3 tables.

1. What are the most and least common weight intervals of the animals purchased?
2. What are the most and least common intervals for lifespan of the animals?
3. What are the most and least common intervals for gestation period of the animals purchased?

Zoo Challenge 3:
Now it is time to put all of your information together and create a presentation. Your presentation should include:

• a listing of the animals you chose and an explanation of why you chose them;
• a picture of each animal you chose in your presentation; and

Keep in mind that you will be reporting your results to the Animals Inc. board (your peers and teacher), so be organized and creative! Remember that the Guidance section has helpful hints, and the Resource section has useful websites

Zoo Challenge 1:

• each type of animal purchased;
• the total amount spent on each category of purchased animals; and
• the total amount spent.

Remember, when writing expressions, you need a defined variable, numbers, and at least one operation. For example, an expression for the total amount spent on zebras might be \$15,000z, where z = total number of zebras purchased.

Zoo Challenge 2:

• An animal’s gestation period is the amount of time the animal carries the infant in the womb. If an animal hatches from an egg, the animal’s incubation period is the amount of time the animal spends in the egg before hatching.
• Refer to prerequisite skills, p. 715 in your textbook for a reminder on how to create a frequency table.

Zoo Challenge 3:
Some of the presentations that you could create are:

• a PowerPoint® presentation,
• a poster,
• a video,
• a newspaper/magazine article, or
• a professional portfolio.
