Video: The Lorax (Youtube)


1.What natural resource did the Once-ler find?

2.What happened to them?

3.The Once-ler used these natural resources to start a business which made and sold a product. What was the name of the product?

4.Why was the Once-ler so determined to make them?

5.How many people and animals were helped by efforts of the Once-ler?

6.The Once-ler said to himself, “If I didn’t do it, someone else would.” Does this justify his actions?

7.The Once-ler was feeling sorry for the Truffula trees, until some event occurred. What happened to change his mind back to being greedy?

8.At the pleading of the Lorax, the Once-ler sarcastically commented, “Shut does the factories? Is that good economics?” What did the Once-ler mean by that statement?

9.One song in The Lorax has the lyrics, “Everybody DO need a thneed.” Why was that not true?

10.How did the Once-ler create a “demand” for his thneeds?

11.How was the thneed used by buyers?

12.The thneed is a mythical item. However, what do you think the thneed represents?

13.What was the symbolism of the last truffula seed and the sign saying “UNLESS?”
A.The next generation has the hope and power to reverse the damage done.
B.The boy can now make lots of money growing more trees and creating more thneeds.
C.The Once-ler turned the factories over to the boy to manage.
D.The boy was to go to a faraway land and start the process all over again there.

The Lorax is an allegory. An allegory is a tale in which objects and actions in the story have meanings outside the story. Characters often stand for abstract ideas like charity, greed, or envy. An allegory is a story with two meanings: a literal one and a symbolic one.

14.Why do you think we never see the Once-ler’s face? Who or what does he represent?

15.Who or what does the Lorax represent?

16.What technology did the Once-ler invent to increase the production of thneeds?

18.Is business growth and development of resources good or bad? Explain.

19.According to the cartoon, what is the result of “progress” and “improved technology?” Give two examples from the cartoon: (Hint: It can be positive or negative)

20.The Lorax thought his views might be considered “old fashioned” and that “progress progresses too fast.” Do you think progress in our modern society is occurring too quickly, or not quickly enough?

21.Why is it important to restore land after such damage has been done?

22.How can we restore the environment after damage is done?

23.Who should pay for such repairing of the environment?

“Sustainable development” is defined as meeting the needs of the present without reducing the ability of people to meet their needs in the future. You might say we can “use it, but don’t abuse it, or we’ll lose it.”

24.Did the Once-ler practice “sustainable development?” How or how not?

25.What mental change occurred in the first half of the 1900s to help Missourians practice sustainable development of forests?

26.Think of an example in our community or area in which we currently do or should practice sustainable development. Are we doing a good or bad job at “using it without abusing it?” What should be done differently?

27.Which do you believe our society most resembles: the Lorax or the Once-ler? Why?

28.The Once-ler learned that he had made a serious mistake. What was his mistake, in your opinion?

29.Many human economic activities are planned for the short-term, perhaps from several to ten or fifteen years. Why is long-term planning that spans several human generations more necessary?

11) How many planets does it take to support YOUR lifestyle if everyone on Earth consumed as much as you?

I hope this opened your eyes to a few environmental problems which we face. One person makes choices which can affect everyone. Think about what you do before you act.

12) Read through the links on the website below. It will help explain galls. And if you don't know what that is, it will come in handy on your test next week.

Click HERE to see the website on Galls.


Due Friday: Rough sketch of your poster project. For details, scroll to the links provided from last week.

Also due Friday: Pages 31 - 33 homework questions (Page 31#1-14, page32 #15-17, page 33 #31, 32, 33, and# 1, 2, 3).

What makes a good Poster?

Go through the powerpoint here



Read through the rules for this contest and start researching about the topic to get background for ideas to use in creating YOUR poster. You are NOT to use the logo for the contest, and material must be original work. (Originality is a plus - the more different your poster while addressing the topic, the better!) Posterboard will be supplied, and the poster handed in by early November; I would like a rough draft (on notebook paper is fine) of what you will be making by Friday, August 22nd.

2015 Poster Contest

Pay attention to the links near the page bottom.("Other Useful Tools and Information for participants to design their posters.) Read through the links for tips about how to draw your poster.



You are NOT to go to any website other than the ones found as links from this page!!!
Doing so may be cause for being removed from computer lab access.

# 4-8 are due today.

1) Due Monday:

Careers exercise

2) Remember, there is the probability of the class going outside in the next week, weather permitting. Make sure to dress appropriately.

3) New Assignment: Your leaf project consists of the following:
A) Collect leaves from 20 different trees (there must be no two leaves from the same species of tree)
B) Press them: this may be done by placing a paper towel or newspaper onto a flat surface, laying the leaves on top, then placing something like magazines or books on top of the leaves for a couple of days. The leaf will dry out and will have been pressed flat.
C) Mount the leaves on paper, one leaf per sheet unless the leaves are small enough not to be crowded - construction paper or notebook paper will suffice - using tape. If the leaf happens to be too large or long for one sheet, tape two together and then mount the leaf onto the paper.
D) Include the following next to the leaf:
Date collected
Location collected (address or lat/long coordinates)
List ALL the identifying characteristics used to identify the tree.
Your Name

*You need to place them in a folder - NOT a binder, unless it just takes up too much room.

4) From this point - Due at the end of the period TODAY.

Go to the following website for a tutorial on tree identification and click on "Click here to Launch the animation":


5) Proceed through the exercise on tree identification which pops up when you click the link above. It's simple, but it may save you some grief when identifying your tree leaves. Taking notes would be good.

6) The link which follows has a nice online tree identification application. Click through it, and see what you can do with it using the following information: Broadleaf, with the leaves being rough on top; Red to Dark purple fruit; Simple; Alternate; Not fan shaped; Toothed; both lobed and unlobed on the same tree. What is your answer?

What Tree Is This?

7)Here is a different tree guide:

The Basics of Tree Identification

Click on each of the links listed under "Clues that you will need to examine", and review each. Make sure you click through each page for each link too - the leaf link has 5 pages. It would be a good idea to take notes on each characteristic while you are looking at the page - it may prove to be the difference between getting a leaf identified correctly, or incorrectly. Note that there is an app for smart phones available on this website.

8) Click on the "Leaf Key" link, and try to identify the tree I'm describing: Simple, lobed, pointed broadleaves with a finely cerrated margin are shaped like a 5 pointed star. It has long leaf stems, arranged alternately on the twigs. The fruit is a spiny ball, and the tree generally grows in low, wet woods.

Use the characteristics listed above with the following key. Did you get the same answer?

What Tree Is It?

Here is one from Butler University - I think you will recognize it!
