The TASK Part 1

Scientists are studying the different animals on the planet Rhomaar. The scientists have collected data for the first twelve years of each animal’s life and they have found out that, unlike humans on Earth, every animal on Rhomaar grows the same amount of centimeters every year. And since Rhomaar is a magical place, all of the animals are born with zero height.


The scientists have only been able to study the animals listed below:

Animals
· Flickerbill: It is 24 centimeters tall when it is 4 years old.
· Diggysee: It is 39 centimeters tall when it is 12 years old.
· Tonypen: It is 30 centimeters tall when it is 5 years old.
· Chucky: It is 45 centimeters tall when it is 10 years old.
· Lightchee: It is 27 centimeters tall when it is 6 years old.
· Stargazer: It is 26 centimeters tall when it is 8 years old.

PART 1
You have been assigned to study the Stargazer. 

a) What is the unit rate for the Stargazer's height?

b) What is the Stargazer's height at 2 years?

c) What is the Stargazer's height at 5 years?

d) Write an equation to represent the relationship between the Stargazer’s age in years (a) and its height in centimeters (h).

e) The animals on Rhomaar live until they reach a height of 90 cm. How many years will the Stargazer be alive? Show your work and explain to support your answer.

The TASK Part 2

PART 2
You have been assigned to study the Stargazer.

· Stargazer: It is 26 centimeters tall when it is 8 years old.

f) Fill in the blanks for the Stargazer's height at each year of its life. (Enter decimals only)

At 1 year old, the Stargazer is _______  centimeters tall. 
At 2 years old, the Stargazer is _______  centimeters tall. 
At 3 years old, the Stargazer is _______  centimeters tall. 
At 4 years old, the Stargazer is _______  centimeters tall. 
At 5 years old, the Stargazer is _______  centimeters tall. 
At 6 years old, the Stargazer is _______  centimeters tall. 
At 7 years old, the Stargazer is _______  centimeters tall. 
At 8 years old, the Stargazer is _______  centimeters tall. 
At 9 years old, the Stargazer is _______  centimeters tall. 
At 10 years old, the Stargazer is _______  centimeters tall. 

g) Use the information from your table in question f) to plot the age and height of the Stargazer on the graph. Plot at least 3 points.
If it is easier for you to graph on paper, you may.

h) The scientists suspect that some animals on the planet Rhomaar grow at the exact same rate.
Match the animals together that grow at the same rate.
Explain or show calculations to support your claims.

Draggable item		Corresponding Item
Stargazer		Same rate as Flickerbill
Lightchee		Same rate as Diggysee
