Interdependence of Living Things – Lesson Plan

Class: (Customize to your use)
Date: (Customize to your use)
Standard(s): (Customize to your use)
Learning Activities and Timing: (Customize to your use. View this
concept’s “Additional Resources” for access to even more useful
materials.)
Key Objective(s):
Concept Objective(s):
Describe how living things interact
Language Objective(s):
Students will be able to analyze the structure of the relationships among concepts in a text,
including relationships among key terms.
Exit Criteria:
When students finish this lesson, they should be able understand interdependence by relating
how their own lives are interconnected with other species with a concept map. They will also
identify symbiotic relationships through a laboratory with anecdotes with supporting evidence.
Students will determine shark’s symbiotic and competitive relationships by watching a video and
answer questions.
1. What does Symbiosis mean?
2. Name an organism and state two things that are interdependent on it. With each
interdependent item, you must state WHY they are interdependent of each other.

3. Recall today’s content and language objective. Evaluate whether you have met these
objectives. Based on your own evaluation, put your paper in one of these categories;
“Clueless, More practice, Sort of got it, I totally understand.”
**To help the teacher gauge their student learning, you can have students evaluate themselves
on the content and language objective with their completed exit tickets. Have students place in
their papers into one of these four categories; “Clueless, More practice, Sort of got it, I totally
understand.”**
Teaching Strategies and Tips:
Introducing the Lesson:
Have students chorally read out loud the Concept and Language objective two times and
have them write it down in their notes.
Think Aloud & Concept Map
Concept map example is provided.
Start relating the concept “Interdependence” with the students by using yourself as an
example. Teach by introducing the lesson with a “Think Aloud” method. Address the question,
“Who/what do you depend on to survive?” Use yourself or a friend you know as an example.
Define your relationships as symbiotic or competitive or both. Take time to explain how you
have determined your relationships based on your reasoning.
Science Inquiry:
Laboratory
The following activity demonstrates and practices the three different types of symbiotic
relationships in agriculture. This also has six short stories to determine the type of relationship
between two species http://oklahoma4h.okstate.edu/aitc/lessons/upper/symbiosis.pdf

Video then Answer Questions
1. This video will display the various relationships sharks have with other species.
“Background:
Sharks and their biological cousins, the rays, are among the highest-profile denizens of the
deep. But sharks are not the solitary killing machines that popular movies and the press might
have us believe. In their marine environment, sharks coexist with numerous other species –
many of whom flock to be near the sharks, rather than running from them in fear. These
excerpts from the NATURE episode “The Secret World of Sharks and Rays” examine the
interrelationships between sharks and other marine species. In many of these cases, the
interaction between two different species mutually benefits each species. But humans, too,
have become an increasingly important player in the lives of sharks – and as they are
increasingly hunted for their fins, sharks are actually becoming more endangered than they are
dangerous. The impact on the marine ecosystem that would result from the disappearance of
sharks would be devastating, but there is still time to save these magnificent creatures, and the
ecosystems that depend on their existence.” - taken from

NATURE: The Secret World of Sharks and Rays, selected segments
Clip 1: “Shark and Turtle”
A battle between a loggerhead turtle and a shark.
Clip 2: “Unlikely travel companions”
A variety of symbiotic relationships exist between sharks and other marine species.
Clip 3: “Sharks and fishermen”
Sharks and fishermen compete for the same catch.
Clip 4: “Collapse of sharks”
This clip shows the destructiveness of the shark fin and shark cartilage industries.

Concept Map – “Relationships”
Each person in the partner has to make their own relationship concept map. Relationship map
has to include their lives, the people and their influence. Have students evaluate their
relationships with others; labeling the relationship as symbiotic, competitive or both. Students
have to give an example of the types by writing underneath each type of relationship.
Common Misconceptions:
None.
Enrichment:
Audio/Reading, then Answer Questions
1. Go to the following website http://sciencenetlinks.com/science-news/science-updates/threeway-symbiosis/
2. Listen and follow along the audio recording. Finish reading information on the three different
3. Go back and take notes
4. Answer the following questions
1. Describe the three-way symbiotic relationship that these researchers discovered.
2. How did the researchers prove that the relationship was beneficial to all three
organisms?
3. In one of the experiments you heard about, the researchers cured some fungus
samples of the virus, and then re-infected them. Suppose these re-infected fungi were
not heat-resistant, even when reintroduced to the grasses. What might this suggest?
4. Can you think of three-way symbiotic relationships in human society?

Concept Map – “Relationships”
This is an individual project. Have students choose a species and do research to find out what
other species do they have a competitive and three types of symbiotic relationship (mutualism,
commensalism and parasitism). Relationship map has to include the type of relationship, and a
short description. An additional illustration would be a bonus.

Review Questions:
