Lesson applying problem-based learning
- 2. What are the things you usually consider whenever you plan to have a vacation/picnic? What is the difference between weather and climate? Why the climate of one country differs from that of others?
- 4. OBJECTIVES: At the end of the lesson, the students are expected 1. Identify the factors affecting the climate in a given situational problem; 2. Brainstorm to come up with one solution to a problem; 3. Infer that there are factors affecting the climate experienced by a certain place;
- 5. Unlocking of terms: Factors – one of the elements contributing to a particular result or situation (Thesaurus.com) Affect - to act on; produce an effect or change in; Climate - the general pattern of weather in a certain area over a long period of time ( Grade 9 LM) - the general prevailing weather conditions of a region, as temperature, air pressure, humidity, precipitation, sunlight intensity and winds throughout the year.
- 7. Group 1 “ When the sun rays strike” Ivy Aguas, 26 y/o an entrepreneur was based in Dubai which is located near the equator. As a businesswoman she travelled a lot. One of her clients wants her to come to his place in Alaska. Inside the airplane bound to Alaska, she reads “Trivia and Facts” magazine which is about the Earth’s tiltation and she quoted, “ The shape of the Earth resulted in uneven heating of the Earth’s surface”. When the airplane landed to an airport in Alaska, she observed that most of the places were covered by ice. On her way to her client’s house, she saw polar ice caps. She asked herself, “ Why is it this place was so cold and the day seems like a dawn?” Why Dubai is so hot while this place is so cold?”. Then, she got asleep.
- 8. Group 2 “ The higher, the colder? Diego Torillo, 28 y/o is a mountain climber from Bacolod City. He visited different countries like Africa which has the highest mountain ranges.On his way to Mt. Kilimanjaro, the highest mountain which stands 5,898 m above sea level, he was so amazed that the peak of the mountain was covered by ice. After the hike, he went back to the Philippines to share his experience with his friends. It was summer, when he decided to visit Baguio city and wondered, “Why people always visit this place during summer?” After the trip, he went back to Bacolod city and noticed that the temperature of his hometown is different from that of the two places. He found out that Bacolod is 10 m above sea level.
- 10. Group 1 1. What is the problem all about? 2. Why does the amount of heat received by places from the equator become less? 3. Why are the coldest places on Earth found near the poles? 4. What is the factor that affects the climate in given problem?
- 11. Group 2 1. What is the problem all about? 2. What is the difference among the places? 3. How altitude affects the climate of an area?
- 12. How is Problem-Based Learning used in the activity? Is it teacher-centered learning or student-centered learning? Explain why?
- 14. What are the factors affecting the climate? Latitude Altitude Bodies of water
- 15. How each factors affect the climate of an area? Latitude: As the latitude increases, the smaller the angle of the sun’s rays strike the surface. Therefore, when the area is farther from the equator, the air temperature is lower. When the place is closer to the equator, the air temperature is higher.
- 16. Altitude: As the altitude increases, the air temperature decreases. For every 1000 m, there is a of 6.5 ̊C. Ultimately, the decrease in temperature is due to the decrease in air pressure.
- 17. Distance from the ocean Places that are far from the bodies of water have extreme climates, as is no immediate bodies water that will help circulate the movement cold and warm air.
- 18. How is problem based used in delivering instruction? What is Problem-based learning all about?
- 20. Why are the coldest places found on Earth found at the poles? Why do mountain climbers wear thick jackets and thick clothes when they go up the mountain? Why do some areas that are far from the bodies of water have extreme climates?
- 21. What will you choose, “a life with problems” or “life without problems”? Why Problem-based learning is important as an emerging current trends in delivering instruction? How Problem-based develop problem solving and critical thinking skills?

Editor's Notes
- #15: The air temperature decreases as the altitude decreases. For every 1000 m, there is a drop of 6.5’C.
