This exploration had 7 weeks long and we make our own meaning of PBL.
Project-based learning is an educational method that involves inspiring students in problem solving and investigative activities to gain deeper knowledge, skills, and experiences; giving students the opportunity to actively explore challenging questions and real-world problems outside of the classroom resulting in realistic products, solutions or other outcomes.
We went to see the students presentation in Kratie and it was good. We had big experience at their because we not sleep in other people’s house we camping it was great the first night but the second night had a big problem but great. It was rain and we run around singing under the rain and it was great. All the students presentation and acting are great. They said they want to continue PBL learning style.
How do airplane fly?
The airplane wing is shaped like an airfoil with a curve along the top. So when the airplane move faster and faster the air pressure on the bottom of the wing is higher than the top so it creates lift force that makes the airplane fly. To overcome the gravity the airplane need have thrust force acting on it which are the engines of the airplane that make the airplane move forward. The engine also has a shape like an airfoil so it can create lift. Drag is like friction that makes the action of the airplane not smooth. 2 types of engines one is the jet engine and another one is the wing. If you in a car and if you put your hand outside of the window horizontally you don’t feel a lot of drag but if you put it as vertically you will feel more drag.
Wing has flap, slat, and aileron during the takeoff flap and slat move downward make the shape of an airfoil. During flight flap and slat go to the original position. To descend an airplane just need to lower the elevator so it produces lift force and if want to climb up just do the reverse. If the to navigate just change make one aileron go up and another down so it will produce lift force and turn.
