What factors can you think of that affect the flight of a glider like a paper airplane? (Answer: Features such as rudders, a streamlined design, weight, ailerons, elevators on the rear ends of the back wings, etc., that affect the flight length, steering and flight distance.) Engineers consider all of these factors when designing airplanes for speed, distance and cargo. Have you made an airplane, only to have it make an immediate nosedive into the ground? Many factors affect airplane flight perrformance. Engineers run airplane models through thousands of tests before building the real thing. How many of you have ever made a paper airplane? How many of you have tried with a friend to see whose airplane can go the farthest or the highest? Did you know that engineers make small-scale models of things like airplanes to test their ideas in a laboratory setting before they build the real thing? Building a model enables engineers and inventors to test their ideas using less expensive materials before the "real thing" is built out of its final-and likely more expensive-material. ![]() International Technology and Engineering Educators Association - Technology Models of all kinds are important for testing solutions.Īlignment agreement: Thanks for your feedback! The iterative process of testing the most promising solutions and modifying what is proposed on the basis of the test results leads to greater refinement and ultimately to an optimal solution. ![]() This lesson focuses on the following Three Dimensional Learning aspects of NGSS:ĭevelop a model to generate data to test ideas about designed systems, including those representing inputs and outputs.Īlignment agreement: Thanks for your feedback!
