Secondary Objective:

• Promoting Environmental Awareness: Through the study of invasive species and their impacts, students will develop a greater sense of environmental awareness and the need for conservation.

Introduction (10 - 12 minutes)

1. Recap of Previous Knowledge: The teacher starts the lesson by reminding the students about the concept of biodiversity and the importance of native species in an ecosystem. They also review the concept of ecosystems, emphasizing the delicate balance that exists between all the organisms and their environment.

2. Problem Situations: The teacher presents two hypothetical scenarios to the students. The first scenario involves a pond in their local park being overrun by a type of aquatic plant that has been introduced from another region. The second scenario involves a bird species that has been introduced to their area and is now outcompeting the local bird species for resources.

3. Real-World Context: The teacher explains to the students that these scenarios are not uncommon and that such situations can have serious consequences for the local ecosystem. They can also have economic impacts, such as reducing the value of property near the affected areas. The teacher can use real-world examples, such as the spread of zebra mussels in the Great Lakes or the impact of the cane toad in Australia, to illustrate the point.

4. Topic Introduction: The teacher introduces the topic of invasive species, explaining that these are non-native species that can cause harm to the environment, economy, or human health. They can outcompete native species for resources, disrupt natural processes, and reduce biodiversity.

5. Attention-Grabbing Facts: To pique the students' interest, the teacher shares two interesting facts. The first is about the kudzu vine, a plant introduced to the United States in the late 1800s, which now covers over 7 million acres of land in the southeastern part of the country. The second is about the brown tree snake, which was accidentally introduced to the island of Guam and has since decimated the native bird population.

6. Topic Relevance: The teacher explains that understanding invasive species is not just an academic exercise. It's a real-world issue that requires action. By learning how to identify and manage invasive species, students can play an active role in protecting their local environment.

Development (20 - 25 minutes)

Activity 1: Invasive Species Classification Game (10 - 12 minutes)

1. Setup: The teacher prepares a series of cards, each featuring a picture and a brief description of a species. The cards include examples of both invasive and non-invasive species that are commonly found in the local area.

2. Group Formation: The students are divided into small groups of 4 to 5. Each group is given a set of these cards.

3. Game Rules: The teacher explains that the groups' task is to sort the cards into two categories: invasive and non-invasive species. The groups are encouraged to discuss and debate before agreeing on their classifications.

4. Discussion and Decision: Each group discusses the characteristics and impacts of the species on their cards. They then decide as a group whether each species is invasive or not.

5. Card Placement: The groups place the cards into two separate piles based on their classification decision.

6. Feedback: After all groups have finished, the teacher goes through the classifications with the class, explaining the correct categorization and discussing the characteristics of invasive species that the groups might have missed.

Activity 2: Invasive Species Impact Role Play (10 - 12 minutes)

1. Setting the Scene: The teacher explains that the students will be acting out a scenario where a new species has been introduced to their local ecosystem. The teacher chooses a common invasive species from the local area and introduces it into the scenario.

2. Role Assignments: The students are divided into groups of 5 or 6. Each group is given a role card describing a different local species, such as a native bird, a local fish, a type of plant, etc.

3. Species Discussion: Within their groups, students discuss how the introduction of the invasive species might affect their assigned species. They consider factors such as competition for resources, predation, and changes to the habitat.

4. Role Play: Each group acts out a short scene where the invasive species is introduced and the impacts on the local species are observed.

5. Discussion and Reflection: After each role play, the class discusses the potential effects of the invasive species on the local ecosystem. The teacher guides the discussion, making sure to touch on points such as changes in biodiversity and the disruption of natural processes.

These hands-on activities provide students with an engaging and interactive way to understand the characteristics and impacts of invasive species. They also encourage teamwork, critical thinking, and problem-solving, which are important skills in environmental science and beyond.

Feedback (8 - 10 minutes)

1. Group Discussion: The teacher brings the class back together for a group discussion. Each group is given a chance to share their solutions or conclusions from the activities. The teacher facilitates this discussion, ensuring that all students have a chance to participate and that the conversation remains focused on the topic of invasive species. (3 - 4 minutes)

2. Connecting Theory and Practice: The teacher then asks the students to reflect on how the activities connect with the theory they have learned about invasive species. They discuss how the characteristics they identified in the classification game and the impacts they observed in the role play align with the definition and effects of invasive species. The teacher emphasizes that the real-world examples they explored in these activities are not just hypotheticals - they are based on real situations that have occurred due to the introduction of invasive species. (2 - 3 minutes)

3. Reflective Questions: The teacher provides a moment for individual reflection and asks the students to consider the following questions:

   • What was the most important concept you learned today about invasive species?
   • How can you apply what you have learned to real-world situations?
   • Are there any questions or concepts you are still unsure about?

   The teacher can write these questions on the board or display them on a slide to help the students focus their thoughts. After a minute or two, the teacher invites the students to share their reflections with the class. This provides an opportunity for the students to process what they have learned and to identify any areas where they may need further clarification. (2 - 3 minutes)

4. Summarizing the Lesson: The teacher ends the feedback session by summarizing the key points of the lesson. They reiterate the definition of invasive species, the characteristics that make them successful invaders, and the impacts they can have on the environment, economy, and human health. They also remind the students of the real-world examples they discussed and the importance of being able to identify and manage invasive species. The teacher encourages the students to continue thinking about these concepts and to be aware of the potential for invasive species in their local area. (1 minute)
