2. 1 Structures & Geometry The project to get you started thinking geometrically! Nancy Powell – Bloomington High School

3. 2 What have these structures have in common? the Panama Canal Mt. Rushmore, the Sears Tower, and the Great Wall of China All are memorable human achievements in structure building!

4. 3 Structure Project Goals Learn & write about structures and the geometric qualities that make them strong Look at types of materials and their geometric designs and strengths Work as a TEAM to design and build a file folder structure Measure its height Test the structure for its strength

5. 4 Procedure: Complete the Internet investigation and research. http://www.teachersnetwork.org/dcs /math/structures/index.html

6. 5 Procedure: Learn about tension and compression via experiments. San Francisco, California_ October 17, 1989 Kobe, Japan - January 17, 1995 http://www.teachersnetwork.org/dcs/math/struc tures/tenscomp.htm

7. 6 Procedure: Interview people that will be helpful in understanding buildings, architecture, and/or structural engineering. http://www.teachersnetwork.org/dcs/math/structures/journal.htm

8. 7 Procedure: Your TEAM will Design and Build a file folder structure & test it for weight held and measure the height of your structure for points!

9. 8 Team/Resources You will be put in teams of 4-5 students. Materials 25 manilla file folders (provided) Elmer’s white glue Paper clips to hold the structure together while it is drying (they MUST be removed before the structure is tested).

10. 9 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 or web page to illustrate the geometry you used.

11. 10 Analysis of Your Design Design your structure Architectural and geometric features Strengths Your strengths relative to geometric design Weaknesses Your weaknesses relative to geometric design

12. 11 Competitive – Yes! Competitors – Other Teams Strengths – Record is 1557 lbs Heights – Record is 26.5 inches We’ll measure and test your structure in the weight room on the due date! Grades will be assigned as indicated on the evaluation sheet. the evaluation sheet

13. 12 Schedule – Days 1 & 2 First two classes and for homework - complete research

14. 13 Schedule – Days 3, 4, 5, & 6 These four days are to be used to design and build your structure while working on your paper or web page as homework! Use a weekend to allow structures to dry.

15. 14 Schedule – Day 7 Test structures and turn in papers

16. 15 Schedule – Day 8 Evaluate your process and success!

17. 16 Celebrate!
