Towers have been a part of developed society for centuries, serving a variety of purposes, from watch towers to modern cell towers. In this activity, student groups design and build three types of towers, engineering them to meet the requirements that they hold an egg one foot high for 15 seconds.

Engineering designs are subject to requirements and constraints, often including limitations on time and budget, and specifications for size, materials, capacity, etc. Engineers design different types of towers to best suit different purposes. Follow the steps of the engineering design process to create an egg holder at the top of tower.Parts of a structure.Types of towers and comparisons.Safe usage of tools and machines.Forces that must be taken into consideration when building structures.1.75460TeachEngineering.orghttp://www.teachengineering.org/collection/wpi_/activities/wpi_tower_investigation/student_worksheet.dochttp://www.teachengineering.org/collection/wpi_/activities/wpi_tower_investigation/student_worksheet.pdfhttp://www.teachengineering.org/collection/wpi_/activities/wpi_tower_investigation/assessment_worksheet.dochttp://www.teachengineering.org/collection/wpi_/activities/wpi_tower_investigation/assessment_worksheet.pdfhttp://www.angelfire.com/me/blkstrpra/aug98.htmlhttp://www.pre-engineering.com/resources/towers.htmS1012153MassachusettsScience2.1 Identify and explain the steps of the engineering design process, i.e., identify the need or problem, research the problem, develop possible solutions, select the best possible solution(s), construct a prototype, test and evaluate, communicate the solution(s), and redesign.68S1009558MassachusettsScience2.2 Demonstrate methods of representing solutions to a design problem, e.g., sketches, orthographic projections, multiview drawings.68S1010C69MassachusettsScience2.4 Identify appropriate materials, tools, and machines needed to construct a prototype of a given engineering design.68S1004F28MassachusettsScience2.5 Explain how such design features as size, shape, weight, function, and cost limitations would affect the construction of a given prototype.68S10257A9MassachusettsScience5.1 Describe and explain parts of a structure, e.g., foundation, flooring, decking, wall, roofing systems.68S100DB96MassachusettsScience5.3 Explain how the forces of tension, compression, torsion, bending, and shear affect the performance of bridges.68United StatesCopyright 2012 - Center for Engineering Educational Outreach, Tufts Universityhttp://www.teachengineering.org/policy_ipp.phphttp://www.teachengineering.org/2011-10-257Teacher
