- The students are asked to speculate on possible causes and effects of these situations, priming them for the upcoming lesson on El Niño and La Niña.
- The teacher then presents two hypothetical scenarios:
-
Real-world Applications (2 - 3 minutes)
- The teacher explains the real-world significance of understanding El Niño and La Niña:
- The teacher highlights the impact of these phenomena on global weather patterns, including the potential for extreme weather events.
- The students are informed about the effects on agriculture, fishing, and even global economy, illustrating the broad implications of these oceanic events.
- The teacher explains the real-world significance of understanding El Niño and La Niña:
-
Topic Introduction and Engagement (2 - 3 minutes)
- To capture the students' attention, the teacher introduces the topic with two intriguing facts:
- The fact that El Niño and La Niña events are part of a cycle known as the El Niño-Southern Oscillation (ENSO) cycle, which is the most important climatic phenomenon on the planet.
- The origin of the names: El Niño, meaning "The Child" in Spanish, was named by South American fishermen who noticed the phenomenon around Christmas, hence associating it with the Christ child. La Niña, meaning "The Girl", was named as a counter to El Niño.
- The teacher prompts students to think about other possible effects these phenomena might have on their local environment, fostering curiosity and setting the stage for the lesson ahead.
- To capture the students' attention, the teacher introduces the topic with two intriguing facts:
Development (25 - 30 minutes)
-
Activity One: Effects of Rising Temperature Simulation (10 - 12 minutes)
- The teacher divides the class into small groups. Each group is given a large transparent container half-filled with water (representing the ocean), a heating element (a lamp or heating pad), and several ice cubes dyed with food coloring (representing cold currents).
- First, students are instructed to drop the ice cubes into the water, observing and discussing the movement and effects of the 'cold currents' within the water.
- Then, they place the heating element near one side of the container to simulate a warm current and observe the changes.
- Using a thermometer, students are asked to measure and record the temperature at both sides of the container throughout the activity.
- As a group, they will discuss their observations and summarize how heat changes the behavior of the currents.
-
Activity Two: Droughts and Flooding Discussion (6 - 8 minutes)
- Keeping the same groups, the teacher presents each with two case studies – one about prolonged drought and another about severe flooding, both attributed to El Niño or La Niña. The case studies are real but simplified accounts of past events.
- Students are asked to discuss the impacts of these weather abnormalities within their groups. List out the problems that arose in the case studies due to these extreme weather events.
- Each group must jot down possible solutions or preventative measures society could take to mitigate these issues.
-
Activity Three: El Niño and La Niña Board Game (8 - 10 minutes)
- Lastly, the class comes together to participate in the El Niño/La Niña board game. The game is designed to have cards with multiple-choice questions related to El Niño and La Niña, which teams must answer correctly to move their pieces forward.
- The teacher divides the class into two large teams and explains the rules of the game.
- The game is designed to test the students' comprehension of the concepts while keeping the atmosphere fun and light.
During these activities, the teacher will monitor the student groups, assisting as needed, answering any questions that arise, and ensuring the students apply their knowledge accurately. The teacher ensures students reiterate the main points of the lesson before moving on.
Feedback (8 - 10 minutes)
-
Group Discussion and Reflection (3 - 4 minutes):
- The teacher brings the class together for a group discussion. Each group presents their observations from the temperature simulation, their thoughts on the case studies, and the solutions or preventative measures they proposed.
- The teacher facilitates discussion, asking probing questions to encourage deeper thinking and understanding.
- The aim of this discussion is to allow students to learn from each other's observations and ideas, demonstrating the diverse effects and impacts of El Niño and La Niña.
-
Connection to Theory (2 - 3 minutes):
- The teacher then helps students link their practical activities and discussions back to the theoretical knowledge imparted at the beginning of the lesson.
- The teacher asks leading questions such as, "How does the temperature simulation relate to the occurrence of El Niño and La Niña?" or "How do the case studies reflect the real-world impacts of these phenomena?"
- The teacher makes sure to highlight the key concepts and facts about El Niño and La Niña, reinforcing the learning objectives of the lesson.
-
Reflection and Unanswered Questions (2 - 3 minutes):
- The teacher then asks the students to reflect individually for a few minutes on what they have learned. They should consider questions such as:
- What was the most important concept learned today?
- Which questions have not yet been answered?
- After reflecting, students are encouraged to share their thoughts with the class. This step allows the teacher to gauge the students' understanding and identify any areas that may need to be revisited in future lessons.
