GeometryHonorsBuilding Project

Objective:

To reinforce and apply students’ knowledge of ratio, volume, unit conversions, and solving algebraically while fostering students’ geometrical creativity and imagination.

Project Overview:

Each student is responsible to build a house miniature within a set of parameters. This is an individual, independent, out-of-class project. Therefore, each student is responsible for planning and finding the time to build the project outside class. Planning ahead and time management arepart of this project.This project is worth two test grades. A 10% deduction will be applied to the final grade for each day the project is submitted late (including non-school days).

Requirements:

1.Thebox volumeV(length x width x height) of the whole thing including the base board to the highest point of the project should be1000V1500 in3.

The size of the floor base areaA of the house (the foot print from the farthest end of each side to the opposite side – not of individual rooms area) should be 120 < A < 150 in2.

The area of the base board to support the house must not exceed225 in2.

The height of the house including the roof should be5 < H < 10 in.

2.To receive a full credit, the project must have the following:

Part I:Written presentation

a.A floor plan on a 8½ x 11 graph paper (includes scale).

b.A scaled drawing of the front view of the house on a 8½ x 11 graph paper (includes scale).

c.A scaled drawing of the side view of the house on a 8½ x 11 graph paper (includes scale).

d.Typed calculation of the volume and the floor area.

e.All of the above should be stapled together with a title page and honor code statement in the front.

f.For the scaled drawings, students may use any scale as long as they fit onto the 8½ x 11 graph paper.

Note: Students are not allowed to use a computerized program or software to draw any of the above scaled drawing. However, students are allowed to refer to the online resources for samples of drawing of the floor plan, the front, and the side view of the house.

Part II:Visual presentation

a.For the model, calculate the cubic feet by using the following scale: 0.25 in : 1 ft or 0.125 in : 1 ft.

b.The house must includeat least a living room, a dining room/kitchen, a bedroom, a bathroom, a garage, windows, doors, and a porch.

c.One of the rooms must be a polygon whose sides are greater than four (e.g. pentagon, hexagon, etc.).

d.The roof must be able to be moved for a look at the interior.

e.Extras can be incorporated but they are not required.

Due Dates:

1.Draft of the written presentationMonday, Jan. 3, 2011

2.Picture of project in progress (at least 1/2 completed)Monday, Jan. 31, 2011

3.Final project (written and visual presentation)Tuesday, Feb.22, 2011

Bring the house model to the Science and Arts Student Gallery and place it on the provided tables.Bring the written presentation (the scaled drawings) to class.Write your name on the bottom of your house and scale somewhere on the base board (not on the bottom so that people can see the scale you are using).

Building Materials:

There are two types of materials that student may use:

1. The foam board (can be obtained at Dollar Tree or Michael’s for about $3 per poster-size board)

2. The regular mat board (can be obtained at Michael’s or Hobby Lobby for about $5 per 32x40 sheet).

To produce a good quality of a cut, you must use a good (sharp) knife/blade. Do not cut yourself though!A student suggested using “Acid-free Book Binding Glue” (cost about $20) for gluing the material together.
