PRINCIPLES OF FLIGHT CHALLENGE - Grade Level 3-8 - Paper Airplane Engineering Design

Aug 22, 2026

PRINCIPLES OF FLIGHT CHALLENGE is a 50-minute STEM activity for Grade 3–8 focused on learning the physics of flight through experimentation and iterative engineering design. Youth design, test, and redesign paper airplanes to achieve a distance goal while adding up to 10 paper clips. The lesson builds understanding of lift, weight (gravity), thrust, and drag using demonstrations, guided questioning, and reflection on performance and design changes.

PRINCIPLES OF FLIGHT CHALLENGE GRADE LEVEL: 3-8 OBJECTIVES: To increase ability to: • design and redesign • generate creative solutions to problems • make sound judgments and form conclusions • understand the physics principles involved in flight TIME: 50 minutes MATERIALS: • Plain white paper – 5 sheets per participant, 3 for instructor • 1 pre-made paper airplane • Paper clips – Up to 10 per youth • Pencil – 1 per youth Submitted by: YMCA of Northern Utah IMPLEMENTATION NOTES: • This activity is designed to help youth learn about the physics of flight through experimentation and engineering design. Youth will be expected to design, test, andredesign their projects in order to meet different criteria. • Youth will be learning concepts through demonstration, and then solidifying their understanding of those concepts through inquiry based learning experimentation. PREPARATION (before the session): 1. Separate paper and paper clips into groups of five sheets and ten paperclips. 2. Set materials in a place that is equally accessible for all youth. 3. Ensure facilitator has sheets of paper on hand for demonstration purposes. At the Y, we believe in a holistic approach to youth development so that all children reach their full potential and become competent and healthy adults. PROCEDURE: 1. ENGAGE AND CONNECT 2 MINUTES Ask: • Who has been on an airplane or something that flies? This could be a helicopter, blimp, or paraglider. Who is able to describe that particular aircraft? Does anyone know why these devices are able to fly? • Have several youth come to the front and draw airplanes. When the youth have finished, ask: What is the same about these drawings of airplanes? What is different? Today we will be talking about the principles scientists and engineers have to consider when designing aircraft! 2. INTRODUCTION AND SET UP 8 MINUTES Communicate the following: • The first principle of flight we will be talking about today is lift. Introduce and demonstrate the concept by doing the following: Hold up paper airplane. Ask youth if they can guess what lifts the paper airplane into the air. Brainstorm ideas, guiding discussion to the wings. The wings on an airplane create lift – lift is created when the wings cut through the air. Some of the air flows underneath the wings, and some flows over the wing and this causes the plane to lift itself into the air. • The second principle of flight is weight (or gravity). Introduce and demonstrate the concept by doing the following: Weight is what counteracts drag. Crumple up a piece of paper and ask youths what direction the paper will go when dropped (youths should answer “down”). Drop the paper – it falls down because the object has mass and weight, and is therefore affected by gravity! We will be giving our planes more weight by adding paperclips to our plane designs. In order to fly, the lift needs to be greater than or equal to the weight! • The third principle of flight is thrust. Introduce and demonstrate the concept by doing the following: Thrust is what moves the airplane forward. Thrust in an airplane is usually generated by jet engines, or by a propeller. In paper airplanes, thrust is commonly generated by the person throwing the plane! Have a youth move to the front and throw the pre-made paper airplane with alot of force, and then with a little bit of force. Ask youths which throw generated more thrust (the more forceful throw). • The fourth principle of flight is drag (or air resistance). Demonstrate drag by doing the following: Have two youths come to the front of the class. Give each youth a piece of paper and tell them to hold it to their chest. Instruct them to run across the room, and let go of the paper when they are halfway to the other side. When the youth lets go, the paper will stay on the youth’s chest even though they are not holding it. This phenomenon is due to the principle of drag. • In

FAQs

What are the four key principles of flight taught in this challenge?

Lift, weight (gravity), thrust, and drag are introduced and demonstrated. Youth connect each principle to behaviors of their paper airplanes.

What is the main challenge goal for students?

Create a paper plane that can fly from one end of the room to the other while holding as much weight (paper clips) as possible.

How do students improve their designs during the activity?

They sketch an initial design, test with attached paper clips, answer questions about results, make final adjustments, and then redesign or retest based on performance.
