CARDBOARD CHAIR

RIVER VALLEY HIGH SCHOOL – MRS DENYEROPTIONAL ACTIVITY

CARDBOARD CHAIR

THE PROJECT:You will research, design, construct and test a full-sized, usable chair of cardboard, masking tape and glue that is capable of holding 200 pounds.

RATIONALE:1. Design is an endless process of solving problems

in a creative way. When people solve problems, they need to:

Identify the problem by stating it clearly Collect information Develop possible solutions Choose the best solution Implement the solution And then evaluate the solution

It sometimes takes many tries before people get a solution to work effectively. There may also be more than one good solution to a problem. New information and events often make better solutions possible, and the whole problem-solving process starts up again.

Every design uses a system, which is a group of parts that work together to achieve a goal. These parts include Input Process Output Feedback

Every design also considers two very important aspects: Form Function

You have the option of using your creative talents to earn lots of extra credit and express your own creativity through this project where you will design and build a cardboard chair.

CARDBOARD CHAIR

CHAIR PROJECT SPECIFICATIONS:The chair must conform to the following specifications:

It must be made completely of cardboard, masking tape and/or glue.

o NO OTHER MATERIAL IS ACCEPTABLE FOR THE STRUCTURAL COMPONENT. No wood, metal, plastic, paper or other material than the cardboard, tape and/or glue is acceptable.

o However, it is acceptable to paint or otherwise decorate the chair after the structure is developed. It is possible to put paper or cloth on the surface for decorative purposes.

o It is also possible to use foam rubber, paper or other padding on the seat and seating portion of the back of the chair for aesthetics and comfort. The limit for this padding is four inches (4"). The padding can in no way affect the structural form of the chair.

It must have both a seat and back. The seat must be between 16” and 18” from the floor. The top of the back must be no less than 30” from the floor.

A person sitting in the chair must be able to sit in a relaxed, comfortable, healthy, and safe position.

It must support 200 pounds for at least three (3) minutes. It should be as attractive as possible.

EXTRA CREDIT PROJECTThis project is a fully optional, extra credit project. Each section of the project will be graded individually on the basis of time lines, content, completion and workmanship. This is a very good way to express yourself and bank quite a few extra credit points.

GATHERING THE MATERIALSEach student is responsible for locating the materials required for building the model and the chair. The construction of the chair will be done outside of the classroom as a homework assignment. Some time will be provided in class to complete the required sketches/drawings.

DESCRIPTION OF ACTIVITIES:

Task #1: Research existing chair designs Study the designs of chairs you see around you. Look up chairs on the Internet and learn what designs have

been used in the past.
