Lesson Plan Course Title: Concepts of Engineering and Technology Session Title: Rubber Band Airplane Performance Objective: After completing this lesson, students will be able to design and construct a rubber band airplane, test the planes to determine which designs are most efficient, analyze the relationship between distance and variables of the plane (wings, weight, fins, center of gravity, etc.) and document the results on the Airplane Design Test Report. Specific Objectives: Design a rubber band plane using set materials. Apply cause and effect relationships of size, air resistance, shape, and balance that affect the plane's flight. Create their own unique rubber band airplane. Apply critical thinking on how to build the airplane. Preparation TEKS Correlations: This lesson, as published, correlates to the following TEKS. Any changes/alterations to the activities may result in the elimination of any or all of the TEKS listed. Concepts of Engineering and Technology: 130.362 (c)(6)(A)(C)(D)(E) ...identify and describe the fundamental processes needed for a project, including design and prototype development; ...use problem-solving techniques to develop technological solutions; ...use consistent units for all measurements and computations; ...assess risks and benefits of a design solution. Interdisciplinary Correlations: English: 110.44 (b)(6)(A)(B) …expand vocabulary through wide reading, listening and discussing; …rely on context to determine meanings of words and phrases such as figurative language, connotation and denotation of words, analogies, idioms, and technical vocabulary. 110.44 (b)(7)(H) …use study strategies such as note taking, outlining, and using study-guide questions to better understand texts; Copyright © Texas Education Agency, 2012. All rights reserved. 1 Mathematical Models with Applications: 111.36 (c)(M.1)(A)(B)(C) ...compare and analyze various methods for solving a real-life problem; ...select a method to solve a problem, defend the method, and justify the reasonableness of the results. Physics: 112.39 (c)(2)(B)(C)(D)(E) ...know that scientific hypotheses are tentative and testable statements that must be capable of being supported or not supported by observational evidence. Hypotheses of durable explanatory power which have been tested over a wide variety of conditions are incorporated into theories; ...know that scientific theories are based on natural and physical phenomena and are capable of being tested by multiple independent researchers. Unlike hypotheses, scientific theories are well-established and highly-reliable explanations, but may be subject to change as new areas of science and new technologies are developed; ...distinguish between scientific hypotheses and scientific theories; ...design and implement investigative procedures, including making observations, asking well-defined questions, formulating testable hypotheses, identifying variables, selecting appropriate equipment and technology, and evaluating numerical answers for reasonableness; 112.39 (c)(3)(A) ...in all fields of science, analyze, evaluate, and critique scientific explanations by using empirical evidence, logical reasoning, and experimental and observational testing, including examining all sides of scientific evidence of those scientific explanations, so as to encourage critical thinking by the student; Teacher Preparation: Understand how to build a rubber band airplane and the factors that will ultimately affect its performance. This project relates design, drafting, and physics since students will be considering basic physic’s principles.

SHOW: Once stude ents have finished their planes, p allow w them to tesst them. Reccord which p plane went the farthest and d which one had the mos st stable flig ht. SAY: This plane (bes st performing plane) went the farthe est because (and let the class discusss this before you answ wer).

Summary S Review (LSI ( Quadra ants I and IV V): Question n: Why did your y plane perform p the way w it did? Answer: Answers will vary. One e possible an nswer: Our p plane was to oo heavy and d because o of that, it did not fly a desirab ble distance. Question n: Why did the t best plan ne fly so nice ely? Answer: Again, answ wers will varry. Should be e similar to g good balancce, little air re esistance, ce enter of gravity y was close to t center of pressure, ettc.

Compete against your fellow classmates! Test your airplanes in a hallway or open area (Test 1). Modify your airplane based on problems seen in your initial test flight and test again (Test 2). 1. Did it fly straight? 2. Did it stall? 3. Did it dive? 4. How far did it travel?
