WHAT I LEARNED ACTIVITY OBJECTIVES: • Determine how warm water and cold water moves during El Niño and La Niña. • Differentiate El Niño and La Niña. • Explain the climate being experienced by landmasses during the event. PROCEDURE: 1. Fill the tray with water to within 1" of the top. 2. Add blue food coloring to the water in until a nice "ocean blue". 3. Pour some mineral oil in a bowl and mix in some red oil-based paint until the oil is evenly colored. 4. Gently pour the oil over the surface of the water. 5. Put the container on the paper and mark East and West at either end. 6. Plug in hair dryer, being careful to keep it away from any water spills. SCENARIO A Turn on the hair dryer and blow wind gently across the oil-topped water from East to West. Guide Questions: 1. What happened to the warm water when the wind blew steadily westward? 2. What do you think is the climate experienced by the places located in the West? SCENARIO B Turn off the hair dryer. Observe what happens to the oil. Guide Questions: 3. What happened to the warm water when the wind stopped blowing westward? 4. What do you think is the climate experienced by the places located in the West? In the East? SCENARIO C Turn on the hair dryer again and blow wind vigorously across the oil-topped water from East to West. Guide Questions: 5. What happened to the warm water when the wind blew strongly westward? What happened to the cold water? 6. What do you think is the climate experienced by the places located in the West? In the East? Guide Questions: 7. Which of the three scenarios depicts El Niño phenomenon? Why do you think so? 8. Which of the three scenarios depicts La Niña phenomenon? Why do you think so? NORMAL CONDITIONS (SCENARIO A) Trade winds move warm water from the Eastern part of the Pacific ocean to the West. EL NIŇO (SCENARIO B) Trade winds weaken and warm water is pushed back to the Eastern part of the Pacific Ocean. LA NIŇA (SCENARIO C) Trade winds blow strongly westward which pushes more warm water to the Western part of the Pacific Ocean. This causes an upwelling of cold water in the Eastern part of the Pacific Ocean. KWL CHART Complete the chart by answering column “What I Learned”.
