Commensalism Teacher Resources
Find Commensalism educational ideas and activities
Offering a comprehensive overview of symbiotic relationships, this presentation would be a great way to introduce or review material covered in a biology class. There are definitions, examples, and a quiz on the meaning of parasitism, mutualism and commensalism. In the quiz, there are a few pictures that teachers may want to swap for better illustrations.
As a result of this lesson, upper elementary ocean explorers will be able to describe several interrelationships: symbiosis, mutualism, commensalism, and parasitism. They learn that the biological richness is increased near seamounts and use this type of community to find examples of each of these relationships. After discussion of these concepts, learners work in groups to research an individual seamount community member. They prepare reports to share with the rest of the class.
The topic is symbiotic relationships, and in this case, we get to look at the relationship between the sea anemone and the hermit crab. They review log entries from a Northwestern Hawaiian Island expedition which occurred in 2002, paying close attention to the observations about hermit crabs and anemones. They discuss symbiosis and how two organisms can mutually benefit from living in close proximity. To assess student understanding the class prepares a role-play to summarize what they've learned.
Use background information and vocabulary to familiarize your students with the concept of symbiosis and the role agriculture plays in the shared relationship. They then write the vocabulary in their lab books or journals, and read the story, listing the symbiotic categories.
Learners investigate the interaction in an oceanic ecosystem. In this symbiotic relationship lesson, high schoolers investigate how ecological relationships evolve over long periods of time in order to maintain balance and stability of the ecosystem. This lesson includes Quicktime video and a rubric.
Eighth graders identify the basic elements of an ecosystem and their individual roles. In this life science lesson plan, 8th graders conduct a scavenger hunt in their local ecosystem. They collect evidence and explain how each component is interconnected with each other.
The activies here are designed to reinforce the differences between the three types of symbiotic relationships. Your high school students complete the included worksheet after reading external sources of information and discuss an imaginary symbiotic creature. The link here is to a wikipedia page, which is open for public editing, and therefore should be double-checked before providing.
In a series of lessons, examine the impact on humans by microcosms in the biosphere. Among the plans structured for students with different abilities and learning styles, are activities describing the symbiotic relationship, drawing the water cycle, identifying pollutants, describing hypozia and relating it to Long Island Sound.
Literature containing life cycle information is available from many sources. Several examples of this type of literature are listed below with a synopsis and sample questions for each. These examples have been taken from a variety of reading and interest levels in the hopes that there will be something for everyone here. This brief survey is not meant to be inclusive, but rather to serve as a starting point.
In this ecosystems instructional activity, students describe the types of community interactions and disturbances that can affect an ecosystem. Students compare the types of symbiosis - mutualism, commensalism, and parasitism. This instructional activity has 9 short answer questions.
