This week we learnt how planes fly by learning what the four forces are. The four forces are thrust, drag, lift and weight. Thrust pushes the plane. Lift lifts the plane in the air, weight pulls the plane down so the plane does not go high up, and drag is the resistance acting against thrust. In flying there is manmade and natural manmade is things such as drones, planes, helicopters, blimps. Natural is things such as bugs, bats, ducks and birds. I wonder if birds did not have wings could they still fly. I also wonder if plans did not have an engine. I think I am multistructural for inferring because I can make an inference but I'm not sure about my inference and gathering data because I can gather data but sometimes It's not always right.
