Objectives
The students will be able to…
Differentiate between an abiotic factor and biotic factor
Describe some of the abiotic and biotic factors of each level of organization
Recognize the differences (similarities) among the levels of organization
Predict how limiting factors can affect organisms
Explain the importance of biodiversity with relationship to abiotic and biotic factors (at a level of organization)
Interpret the connections throughout the environment with regards to extinction/survival of species as well as negative impacts to the abiotic factors.
Lesson Essential Question(s)
- How do organisms interact and depend on each other and their environment for survival?
- How is the survival of species and their ability to adapt affected by natural and human induced environmental changes?
Duration

Suggested Instructional Strategies
W-Students will have the essential questions posted on the board. Use humans as the example through the varied levels of organization (also show how “we” differ from other forms of life). Refer to other general forms of categorizing which leads to organization. (for example a file cabinet used to organize bills, documents, receipts, and records.) Student involvement with the activities, discussion and exit “requests.”
H-“Variety is the spice of life!” where have you heard this and what does it mean? **make connection for the student!
E-Via the computer, the students will study/research their organism and its levels of organization. The Lorax connection to our world.
R-When students examine the 3rd column of their environmental resistance chart, they will have the opportunity to reflect on the impact various limiting factors will have on life. Considering human induced limiting factors, students will have the opportunity to provide feedback on how we cause this to happen and what we can do to “start” to change these actions. The Lorax review with sticky notes. With their thoughts from The Lorax, completion of the word UNLESS.
E-Dr. Seuss intended for The Lorax to end with individual ideas expressed using …”Unless…” …this should lend itself to student evaluation if they feel comfortable enough to know that their opinion/idea counts!
T-a. providing handouts, access to various environmental science books for Day 1. b. allowing Open ended/student input for Day 2.
O-By using very broad questioning at the end of this lesson (Day 2) to have students consider their daily actions and how these actions can impact their surroundings. Stimulate student understanding to the connectedness of our planet. This would be a good starting point for a weekly reflection journal.
Instructional Procedures
Independent Activity (BDA, Do Now, KWL, Guided Reading, Word Splash, Expert Jigsaw, etc.) DAY 1: Introduction to the lesson…KWL chart…What do you know about biodiversity? What do you want to know about biodiversity? What have you learned about biodiversity? (individual work). Also, write down the first thing that comes to mind when I say “variety is the spice of life.” Does your answer have any connection to biodiversity? On the board, make the connections with the students.
DAY 2: Continuation of yesterday’s lesson will begin with the students engaged in a DO NOW…”list two examples of how yesterday’s lesson showed our planet is a model of connections. (3 minute time frame) Random Reporting by the students to express their answers and begin discussion. At this point, students will place their creative concentric circle form on their desk for all students to observe as the class will do a GALLERY WALK. Students are free to express the positive things they see on the work of their peers.
|
Pair Share (Peer Revising, Text Rendering, Document Review, etc.) DAY 1: Using their KWL charts, each student will be randomly grouped with three other students to “elbow” share with two of the members of their group their charts. Focus will be on what the students already know about biodiversity.
|
Whole Class, Mini Lesson (Whip, Literature Circle, Guided Lecture, etc.) DAY 1: Using Whip, an overall list will be generated on the board via teacher instructions. Any information that does NOT directly fit into the KWL chart, but may impact the “results” of biodiversity will be added. Connections may be made at this point or at the end of the class discussion. Further topic information will be given to the students via a study guide complete with diagrams and examples. Review. **Within the discussion, Students will take a few minutes and pair-share a list of factors (ENVIRONMENTAL RESISTANCE) that affect man’s everyday existence. Beside this list, each pair of students will list “similar” factors that affect all other life. Noting similar and identical “factors.” Once these two columns are complete, the students will create a third column explaining How these factors affect either or both man and all other life. Lastly, the students will go through the first two columns noting abiotic and biotic factors (** for abiotic and * for biotic). The chart layout may look like the following: ---------------------------------------------- ENVIRONMENTAL RESISTANCE Factors affecting Factors affecting How Factors MAN All other LIFE affect MAN/LIFE
Note…students should think of examples of plants, animals, microorganisms, fungi in order to complete the middle column
** note abiotic factor * notes biotic factor -------------------------------------------------- Again, pair share their charts followed by class discussion. This chart should lead to questions from the students (if not, teacher directed)…Are predators considered an example of environmental resistance? Is man responsible for many of these environmental resistance factors? Can disease be both natural and “human induced?” Do some factors have both biotic and biotic components?
Hand out a blank worksheet with several drawn circles…Six…concentric circles. Give students a few minutes to label each circle using the following terms…species, population, community, ecosystem, biome, biosphere. *Mix-up words on the board. Make sure that students know there is a definite connection with these words. Check for understanding by randomly calling on some students. At this point, the students will create their own vocabulary guide by completing the worksheet with coordinating definitions, possible pictures and/or examples. *Each each level of organization/definition must show a connection to the previous level (smaller circle). Lastly, each student’s worksheet must have an organism in the very center of all circles! This organism can not be a human. If possible, provide students with computer access …only to fulfill the details/pictures of the specific example…sloth, three-toed sloth (species), three-toed sloth with community of poison arrow frogs, morpho butterfly, boa constrictor…, ecosystem…rainforest of Brazil, biome…South and Central American Rainforests, fits into the Big Biosphere. Computer access is given to the students who have shown an understanding of the connections…set up their examples/definitions first!
Day 2: The focus of the lesson today will be on human induced environmental changes. Why and how do we impact every level of ecological organization?...brief group discussion that should lead to values, greed, overconsumption etc. Show the video The Lorax. –brief guide to fill out/outline -sticky notes…students are to write down one value or feeling per sticky note (positive or negative) as to why the environment changes in throughout the movie. These values are taken from the perspective of the main character (one color sticky notes). ALSO, use a different color of sticky notes and do the same for the Lorax character. The third color of sticky note is to list individually all the noticeable limiting factors to the Environment. Fourth color…survival “tactics” or “adaptations.” After the movie, students will post all their notes on one of 3 pieces of bulletin board paper….main character, the Lorax, the environment’s limiting factors. *Eliminate duplicate answers. Do the negatives outweigh the positives? What was Dr. Seuss trying to get across to his audience? Did the music or background have an effect on the positive or negative parts of the movie? **These are all good questions to discuss in a whole group setting. Point out how animal “adapt” to survive. After discussion and checking for completion of the study guide, students have one final reflection. Hand out a paper with the word UNLESS written across it. What does the Lorax mean when he says “unless” at the end of the movie? How can we learn from this word? …UNLESS what?... *finish this paper, make it creative, relate the word to our surroundings, give examples! |

Whole Class Discussion, Reflection (Ticket Out the Door, Response Sheet, KWL, 3-2-1, etc.)
DAY 1: 3-2-1 form…based on today’s topic: “In general, 3 limiting factors, 2 levels of organization, 1 question you have about this topic…form to be turned in. This can be used as part of Day 2 introduction.
DAY 2: Completion of the phrasing “UNLESS…..” is the student’s Ticket Out the Door! Completion means relating the Lorax’s world to our world! (via words and/or drawings).

Formative Assessment
Observation and Evaluation of groups as they a) discuss the common threads with their KWL Charts b) complete the environmental resistance assignment. Check for understanding of the last column of the chart (HOW factors affect man and other living things). It is here that students must have specific examples. Active engagement with The Lorax sticky note activity/discussion will also be noted for assessment. If possible, a teacher generated check list will be used to assess student involvement/checking for understanding.
The concentric circle worksheet, designed by the student, will be assigned a formative assessment numerical grade.
