Structure Project Goals

Learn & write about structures and thegeometric qualities that make them

strong Look at types of materials and their

geometric designs and strengths

Work as a TEAM to design and build afile folder structure Measure its height Test the structure for its strength

Did you know? Winds blowing at

the top of a 100-

story skyscraper are

more powerful tanthose halfway down.

Procedure: Complete the Internet

investigation and research.

What effect does shape have onthe strength of a structure?

How does nature influencedesign?

What is structural engineering? What is corrugation?

Did you know? Lower buildings are made from

lightweight materials to minimize

damage to the surrounding area if theycollapse in an earthquake.

Taller buildings have flexible internal

supports, allowing them to move withthe force of an earthquake withoutbreaking.

What do you think of this

building?This 6-story NunotaniOffice Building in Tokyo is

sturdier than it looks. Itssloping walls, ceilings, &floors are designed towithstand destruction by

earthquake.

Procedure: Interview people

that will be helpful

in understandingbuildings,architecture, and/or

structuralengineering.

Did you know? An architectarchitect is a person who designs buildings. What are the three things that an architect

considers when designing a building? FunctionFunction every building has a purpose AppearanceAppearance the look should relate back to its

function, the choice of materials, & the climate DurabilityDurability building must survive the effects of

weather and be easy to repair.

You cant believe that file folders can

be strong enough to hold weight suchas a 25-pound weight?

Structural engineers have some ideas.

Check out this movie! Engineer YsraelSeinuk talks about Structural Engineering:

Team/ResourcesYou will be put in teams of 4-5

students. Materials

10 manilla file folders (provided) Elmers white glue Paper clips and rubber bands to hold the

structure together while it is drying (theyMUST be removed before the structure istested).

Technology Use the phone and/or the Internet email to contact

people that might be of help in your design.

Use the Internet for research & design ideas Use the Computer to write your paper or create a

web page. Use the Digital camera to document your design

and building process and final structure. Insert your photos into your paper, web page, or

video to illustrate the geometry you used.

Well measure and test your structure in

the weight room on the due date! Grades will be assigned as indicated on

the evaluation sheet.
