Simple Paper HelicopterĪ simple paper helicopter can be made easily at home or school. The Physics of Paper Helicopters – Autorotation ( 4:53)įraming the analysis in terms of Newton’s Third Law of Motion, a pair of equal and opposite forces acting horizontally under each blade and on the body of the paper helicopter cause rotation. This high pressure results in equal and opposite opposing forces that cause the spin. The helicopter descends due to unbalanced forces: The weight of the helicopters is greater than the lift force of air.ĢBrokeScientists studied the airflow around a helicopter and found that there were high-pressure areas under the blades. As a result of the horizontal equal, opposite, and offset forces, the helicopter spins around as it descends. The lift force of the air pushes on each of the blades equally but in opposite directions, horizontally and vertically. When dropped, the helicopter’s mass experiences gravity, and it naturally falls to the floor which causes paper blades to bend slightly upward due to lift. Paper helicopters spin because of the earth’s gravity, lift, and configuration of the rotors. These models are typically created with two blades and dropped from a fixed height and spin as they descend. Traditional paper helicopters do not use a power source to spin their blades and create lift. The physics of paper helicopters are different from real helicopters. These rotor blades are sometimes referred to as simply rotors or blades. In basic terms, an actual helicopter is a type of aircraft that creates lift (an upward force of air) with horizontally spinning rotor blades. MS-ETS1-2 Engineering Design – Evaluate competing design solutions using a systematic process to determine how well they meet the criteria and constraints of the problem.3-5-ETS1-3 Engineering Design – Plan and conduct an investigation collaboratively to produce data to serve as the basis for evidence, using fair tests in which variables are controlled and the number of trials considered.This paper helicopter experiment is a simple introduction to experimental design and will target this testable science question:ĭoes changing the blade length of a paper helicopter affect how long it stays in the air? (Keep reading, however, this question needs a bit of clarification.) This lesson covers methods of data gathering and provides teachers with easy-to-use activity resources. It can be extended above and below these grade levels as well. The specific paper helicopter lesson outlined in this blog post targets students in upper elementary and middle school. Teachers of all experience levels can take advantage of the learning opportunities provided by experimenting with paper helicopters. More open assignments are suitable for independent students at the higher grade levels where the teacher acts as a facilitator. Paper helicopter lessons with more structure would generally target lower grade levels. These levels of investigation range from more structured to less structured which suits various grade levels and abilities. The ASTC Science World Society concisely explains the many levels of inquiry teachers can offer students when conducting paper helicopter experiments. Paper helicopters provide educators with easy-to-do experiments to help students learn the scientific method. Simple quantifiable scenarios can be examined and several criteria for success can be defined and explored. In fact, there are so many paper helicopter materials, lessons, and instructions online, it’s hard to know where to start! Paper Helicopter – 3D Model and 2D Template These models offer teachers easy STEM activities with paper and generate authentic data in the classroom. Thank you for your support!Ī paper helicopter experiment is a fantastic hands-on, and low-budget way for students to explore cause and effect relationships in experimental design.
