This experiential learning resource introduces students to the world of macroinvertebrates and the factors that negatively impact wetlands. A game approach is used to explore the effects of pollution on aquatic macroinvertebrate species. Then students visit a local wetland to search for, and identify the creatures that inhabit the marsh. During their investigation students consider the positive and negative impacts of human activity and learn how factors such as invasive species can affect the health of ecosystems. They also use scientific equipment and gain a deeper understanding of scientific vocabulary related to freshwater systems. Activities in two lessons include:
This resource would be particularly valuable as an accompaniment to any unit on habitats or interactions within ecosystems. After discussing the results of the "Macroinvertebrate Mayhem" game students could be presented with several different scenarios where the number of pollution tolerant and intolerant organisms varies. They could identify which scenarios demonstrate a healthy habitat compared to an unhealthy habitat. Students could then create their own wetland on paper and cut and paste pictures of various aquatic organisms onto their wetland to show their knowledge that a healthy ecosystem contains a large diversity of organisms.
From the invertebrates they collect in the wetland sampling activity students can categorize and sort the organisms by pollution tolerance. They can chart their data and compare results with each other. Then they can analyze their results and draw conclusions about the health of the wetland they sampled. Students could also brainstorm ways to keep the wetland healthy if the results indicate it is doing well, or if there is a problem then they can propose solutions. These activities could be expanded into an action project where students "adopt" a local wetland and develop strategies to inform the community about how to protect this valuable ecosystem.
The following tool will allow you to explore the relevant curriculum matches for this resource. To start, select a province listed below.
|Consideration of Alternative Perspectives||Good|
The "Marcroinvertebrate Mayhem" game has students considering the positive and negative impacts of humans on ecosystem health. The game also develops a deeper understanding of the dependence of humans on healthy wetlands. The activity is reinforced by the exploration of a local wetland where students can visualize their new learning.
|Consideration of Alternative Perspectives: |
|Multiple Dimensions of Problems & Solutions||Good|
As students consider how development can impact on ecosystem health they will also learn about the social and economic decisions that are a necessary component of protecting the environment.
|Multiple Dimensions of Problems & Solutions: |
Effectively addresses the environmental, economic and social dimensions of the issue(s) being explored.
A variety of experiences fosters deeper thinking about wetland ecosystems and students consider new information through presentation, observation and experiential learning.
|Respects Complexity: |
The complexity of the problems/issues being discussed is respected.
|Acting on Learning||Poor/Not considered|
Students will develop a deeper awareness of the value of wetlands but there are no specific wetland conservation action projects included with this resource.
|Acting on Learning: |
Learning moves from understanding issues to working towards positive change — in personal lifestyle, in school, in the community, or for the planet
Although there are no formal values clarification activities in this resource, students should experience an attachment to wetland habitats that they may not have had previously. This will translate into a more fully-developed concern for wetland conservation and protection.
|Values Education: |
Students are explicitly provided with opportunities to identify, clarify and express their own beliefs/values.
|Empathy & Respect for Humans||Poor/Not considered|
Not considered in this resource.
|Empathy & Respect for Humans: Empathy and respect are fostered for diverse groups of humans (including different genders, ethnic groups, sexual preferences, etc.).|
|Personal Affinity with Earth||Good|
Wetlands are among the most threatened types of ecosystems on our planet and it is imperative that young people develop respect for these habitats. This resource fosters an understanding of the importance of wetland conservation through an experiential approach that provides a meaningful experience to students.
|Personal Affinity with Earth: |
Encourages a personal affinity with -the natural world.
Wetlands are found everywhere and this resource is extremely relevant in all geographic regions & communities in Canada.
|Locally-Focused Learning: |
Includes learning experiences that take advantage of issues/elements within the local community.
|Past, Present & Future||Poor/Not considered|
Not considered in this resource.
|Past, Present & Future: Promotes an understanding of the past, a sense of the present, and a positive vision for the future.|
The hands-on, experiential learning that occurs in a wetland provides numerous opportunities for students to make meaningful connections between new information and what they already know.
Lessons are structured so that multiple/complex answers are possible; students are not steered toward one 'right' answer.
This resource is science based. However the game incorporates math outcomes when students tally the invertebrates at the end. ELA aspects are included in the assessment activity which requires students to write a reflection about their experience.
|Integrated Learning: |
Learning brings together content and skills from more than one subject area
Both activities in this resource are entirely hands-on and allow for exploration and discovery.
|Inquiry Learning: |
Learning is directed by questions, problems, or challenges that students work to address.
Although not formally identified, the hands-on approach in this resource will appeal to multiple learning styles and abilities.
|Differentiated Instruction: |
Activities address a range of student learning styles, abilities and readiness.
|Experiential Learning||Very Good|
Both of the lessons in this resource are learner centred and activity based. Students also participate in an authentic scientific investigation when they do the wetland dip netting activity.
|Experiential Learning: |
Authentic learning experiences are provided
There is an opportunity for some small group or pairs learning in the dip netting activity . Students can also support each other in the invertebrate identification tasks.
|Cooperative Learning: |
Group and cooperative learning strategies are a priority.
|Assessment & Evaluation||Satisfactory|
There is an assessment activity included with the resource which requires students to write a one page journal entry about their new learning. This assessment would be best used formatively to determine the level of students understanding. There are no other assessments included with the resource.
|Assessment & Evaluation: Tools are provided that help students and teachers to capture formative and summative information about students' learning and performance. These tools may include reflection questions, checklists, rubrics, etc.|
The activities encourage student consultation with each other as they learn about methods used to sort and classify aquatic invertebrates.
|Peer Teaching: |
Provides opportunities for students to actively present their knowledge and skills to peers and/or act as teachers and mentors.
The "Macroinvertebrate Mayhem" game presents students with authentic scenarios of how the health of a wetland can be impacted by pollution. Students carry this new learning into their own scientific investigation of an actual wetland and use their knowledge to make a decision about the relative health of that wetland.
|Case Studies: |
Relevant case studies are included. Case studies are thorough descriptions of real events from real situations that students use to explore concepts in an authentic context.
|Locus of Control||Satisfactory|
Students learn authentic skills such as aquatic invertebrate identification that can be used to further explore the issue of pollution and its impacts on the health of aquatic ecosystems.
|Locus of Control: Meaningful opportunities are provided for students to choose elements of program content, the medium in which they wish to work, and/or to go deeper into a chosen issue.|
