Plan de Clase: Impact of Climate Change on Local and Global Ecosystems

Objective of Learning (SMART)

By the end of this lesson, students will be able to describe at least three effects of climate change on ecosystems, explain these effects using simple cause-effect models, and propose basic actions to help protect their local environment, demonstrating understanding through group presentations and a collaborative poster activity.

Materials and Resources

• Projector and slides with images and simple phrases in English
• Printed cards with pictures and keywords about ecosystems and climate effects (e.g., animals, plants, temperature, rain, pollution)
• Large paper sheets or poster boards for group work
• Colored markers, crayons, and glue sticks
• Simple worksheets for reflection and drawing
• Plastic containers, leaves, soil, water, ice cubes (for a simple manipulable ecosystem model)
• Timer or clock to manage activity times

Evaluation Criteria

• Indagación (Inquiry): Student asks questions and identifies relevant information about climate change effects.
• Explanation of Phenomena: Student explains cause-effect relationships with support from examples and visuals.
• Use of Scientific Knowledge: Student applies learned concepts to suggest possible solutions for protecting ecosystems.
• Collaboration and Communication: Student actively participates in group work and communicates ideas clearly in simple English.

Class Structure

1. Inicio (Start) - 15 minutes

Goal: Motivate students and activate prior knowledge about ecosystems and climate change.

• Teacher: Begin with a warm greeting. Show simple images of local and global ecosystems (forest, river, ocean, animals). Use short and clear English phrases: “Look! This is a forest. This is a river.”
• Teacher: Ask simple questions to activate prior knowledge:
  • “What is an ecosystem?”
  • “What do animals and plants need to live?”
  • “What is climate?”
  • “Have you heard about climate change?”
• Students: Respond orally or by raising hands. Respond in short phrases or gestures.
• Teacher: Show a short short video or animation (2-3 minutes) with simple narration about climate change affecting animals and plants.

2. Desarrollo (Development) - 40 minutes

Activity 1: Manipulative Ecosystem Model (20 minutes)

• Teacher: Divide students into small groups (4-5 students) and give each group plastic containers with soil, leaves, water, and ice cubes.
• Teacher: Explain in simple English: “This is a small ecosystem. Soil, water, plants, animals live here. Ice is cold weather.”
• Teacher: Ask students to observe what happens when the ice melts. “What changes? What do you see?”
• Students: Manipulate materials, discuss within group, note observations.
• Teacher: Guide students to understand that temperature changes affect ecosystems (melting ice = warmer climate).

Activity 2: Group Poster - Effects of Climate Change (20 minutes)

• Teacher: Provide poster boards, markers, and printed cards with keywords and pictures (heat, rain, animals, plants, pollution).
• Teacher: Ask groups to create a poster showing 3 effects of climate change on ecosystems using drawings and cards.
• Teacher: Use guiding questions to support students: “What happens if it is very hot? What happens if little rain? How do animals feel?”
• Students: Collaborate to organize ideas, draw, and paste cards on posters.
• Teacher: Monitor groups, support students with language and content (using simple English), help those with special needs by adjusting instructions or giving extra time.

3. Cierre (Closure) - 15 minutes

• Teacher: Invite each group to briefly present their poster in simple English: “Our poster shows...”, “Climate change makes...”, “We can help by...”
• Teacher: Summarize key points about how climate change affects ecosystems locally and globally, repeating simple phrases.
• Teacher: Facilitate a metacognitive reflection: “What did you learn today? What surprised you? How can we help our environment?”
• Students: Share answers orally or by drawing on a worksheet.
• Teacher: Conduct a quick formative evaluation with a simple quiz or thumbs-up/down gestures to check understanding.

Strategies for DUA and PIAR

• Multiple means of representation: Use images, manipulatives, spoken and written words, and videos to reach diverse learners.
• Multiple means of action and expression: Allow students to respond verbally, by drawing, or by physical manipulation.
• Multiple means of engagement: Use group work, hands-on materials, and simple gamified elements (poster creation, presentations).
• Adjustments for PIAR: Provide extra time, simplified instructions, one-on-one support during activities, and peer helpers.
• Language support: Use simple English vocabulary and repeat key words with visuals; encourage native language explanations if needed within groups.

Summary

This lesson uses collaborative, hands-on activities and simple English to teach primary students about the impact of climate change on ecosystems. It promotes scientific inquiry, critical explanation of phenomena, and application of knowledge through group poster creation and ecosystem modeling. The class integrates DUA and PIAR principles to support diverse learners and prepares students to appreciate the environment and their role in protecting it.
