Introduction (10 - 12 minutes)

1. The teacher starts by reminding students of the basic concepts related to weather, climate, and oceanic currents that they have previously learned. This will include a brief recap of the central role of the oceans in influencing global weather patterns.

2. The teacher then presents two problem situations that serve as starters for the development of the theory.

   • The first situation could be a hypothetical scenario where a fishing community experiences a sudden drop in fish catch. The students are asked to think about possible causes for this, considering the impact of weather and oceanic conditions on marine life.
   • The second situation could be a real-world example where a coastal city experiences unusually warm weather during winter. Students are asked to reflect on why this could be happening, considering the influence of oceanic currents on local weather patterns.

3. The teacher contextualizes the importance of the topic by discussing its real-world applications and impacts. El Niño and La Niña phenomena have significant implications for weather prediction, disaster management, and even global food security. For instance, the teacher could highlight the severe droughts and floods that have been associated with these phenomena in different parts of the world.

4. To grab students' attention, the teacher shares two intriguing facts or stories related to El Niño and La Niña.

   • The first could be about the impacts of the 1997-1998 El Niño event, which was one of the strongest on record, causing widespread coral bleaching, forest fires, and disrupting global weather patterns.
   • The second could be about the name "El Niño", which comes from the Spanish term for "the boy child", as it was initially identified by fishermen in the Pacific who noticed that the warm current often arrived around Christmas, hence the name.

5. The teacher then introduces the topic formally, explaining that El Niño and La Niña are natural climate phenomena that result from interactions between the ocean and the atmosphere in the tropical Pacific. The teacher tells the students that they will be exploring these phenomena in more depth and learning about their causes, effects, and impacts in today's lesson.

Development

Pre-Class Activities (15 - 20 minutes)

1. Reading Assignment: The teacher provides students with an online article or a chapter from their environmental science textbook that explains the El Niño and La Niña phenomena in simple terms. The reading material should include information on the causes, effects, and impacts of these phenomena.

2. Video Watching: The teacher assigns a short (maximum 10 minutes) educational video that visually explains the El Niño and La Niña phenomena. The video should be engaging and use animations or graphics to illustrate the complex oceanic and atmospheric processes involved.

3. Note-Taking: Students are expected to take notes while reading and watching the video. They should focus on key terms, processes, and impacts of El Niño and La Niña.

In-Class Activities (20 - 25 minutes)

Activity 1: Weather Report Role Play

1. The teacher divides the class into groups of 4-5 students each. Each group is then assigned a specific region around the world (e.g., coastal areas of South America, Australia, or Asia) known for experiencing distinct El Niño or La Niña weather patterns.

2. The groups are given 10 minutes to research and understand the typical weather patterns of their assigned region during an El Niño or La Niña event. They should also look for real-world examples of the impacts of these phenomena on the region's environment, economy, and society.

3. Once the research phase is completed, each group is tasked to prepare a short "weather report" for their region. This report should include information about the expected changes in weather, possible impacts, and any necessary precautions that the local population or authorities might need to take.

4. Finally, each group presents their weather report to the class, explaining the potential effects of El Niño or La Niña on their assigned region in a clear and engaging manner. The teacher facilitates the presentations, provides feedback, and corrects any misconceptions.

Activity 2: Oceanic Currents and Weather Patterns Puzzle

1. The teacher prepares a puzzle with the basic concepts related to El Niño and La Niña phenomena. This could be a crossword, a word search, or a jigsaw puzzle.

2. The teacher explains the rules of the puzzle game to the students, emphasizing that they should work collaboratively in their groups to solve it.

3. Each group is given a puzzle and a set of clue cards. The clue cards contain statements related to the causes, effects, and impacts of El Niño and La Niña. The students have to match the correct clue with the corresponding spot on the puzzle.

4. As the groups complete their puzzles, the teacher circulates around the class, answering any questions and providing guidance as needed.

5. Once a group finishes their puzzle, they should raise their hand. The teacher then checks the group's answers and, if correct, the group receives a small prize (e.g., a sticker, a candy) as a reward for their efforts.

6. The first group to complete the puzzle correctly wins a bigger prize, like a class privilege (e.g., extra 5 minutes break time, first in line for lunch).

7. At the end of the activity, the teacher reviews the solved puzzle with the class, reinforcing the key concepts of El Niño and La Niña phenomena.

Through these activities, the students are not only engaging with the content but also developing research, collaboration, and problem-solving skills in a fun and interactive way.

Feedback (5 - 7 minutes)

1. The teacher initiates a group discussion by asking each group to share their solutions or conclusions from the activities. Each group is given up to 3 minutes to present their findings. The teacher ensures that the discussion is focused on the key concepts of El Niño and La Niña, their causes, effects, and impacts. This step allows for a comprehensive understanding of the topic as students learn from each other's perspectives.

2. The teacher then facilitates a reflection session, asking the students to connect what they have learned with the real-world examples they discussed during the activities. The teacher can ask questions like:

   • "How do the weather changes during El Niño or La Niña affect the lives of people in those regions?"
   • "Can you think of any other real-world examples where El Niño or La Niña have had significant impacts?"
   • "How does understanding these phenomena help us in predicting and preparing for extreme weather events?"

   This step encourages students to think critically about the topic and its relevance in their lives, promoting a deeper understanding of the subject matter.

3. The teacher then assesses the students' understanding of the topic by asking a few quick questions or conducting a brief quiz. This could be done orally or using online tools such as Kahoot or Quizizz. The questions should cover the main points of the lesson, such as the causes of El Niño and La Niña, their effects on weather and climate, and their global impacts.

4. After the assessment, the teacher provides immediate feedback on the students' performance, highlighting correct answers and explaining any misconceptions. The teacher also praises the students for their active participation and efforts during the activities.

5. To conclude the feedback stage, the teacher asks the students to reflect for a minute on the most important concept they learned today. This reflection can be done silently or shared with the class, depending on the teacher's preference. This final step helps to consolidate the learning and allows the students to appreciate their progress in understanding the topic.

6. The teacher wraps up the lesson by summarizing the main points about El Niño and La Niña, reinforcing the key concepts, and providing a brief overview of the next lesson topic. The teacher also encourages the students to continue exploring the topic on their own and to bring any further questions or insights to the next class.
