Name:
Geometry Polyhedron Project
Due May17, 2010
This sheet must be submitted with you project.
If you are absent due to a school activity, the project is due before May 17. If you are ill on May 17, your project is due the day you return to school.
- Construct a platonic solid, icosahedron or dodecahedron.
- Make a cohesive, colorful design that covers your platonic solid. Preprinted paper or computer generated images are not acceptable.
- Calculate the surface area of your Platonic Solid. Be sure to clearly list each step in your calculation process showing all of your work.
Specifications:
- Material: poster board(s)
- Each edge must measure more than 10 centimeters. (All edges will be congruent.)
- Your polyhedron may be bound with glue. If tape is used, it must not be visible.
Be prepared to present a brief description of your project to the class. Maximum one minute.
Place your calculations for surface area on a separate sheet of paper and attach to the back of this paper. Enter your final answer for surface area below.
Dodecahedron with side lengths of ______or Icosahedron with side lengths of ______
Surface Area ______cm2
Your project will not be graded without this rubric.
CATEGORY / 20points / 16points / 12points / 10pointsQuality of Construction / The polyhedron shows considerable attention to construction. The edges are straight.
No gaps long the edges. No tape or glue showing. / The polyhedron shows attention to construction. Most edges are straight. One or two gaps in the edges. No tape or glue showing. / The polyhedron shows some attention to construction. Some edges are straight. Several gaps between edges. / The polyhedron was put together sloppily. Many gaps between edges. Tape showing.
Accuracy of Faces / The faces are congruent and regular. / Most faces are regular and congruent. / Some faces are congruent and/or regular. / Faces are not congruent and/or regular.
Creativity / Faces reflect an exceptional degree of student creativity with use of color and design in their creation. / Faces used in the polyhedron reflect some student creativity. / Use of color or design is average in nature. / Very little time and/or consideration is apparent in design.
Accuracy of Construction / The polyhedron is regular. / Polyhedron was not quite symmetrical. / Polyhedron was not symmetrical. / Material could not support the weight of the faces.
Accuracy of Computations / All computations are correct. / One error was made in the computation of the surface area. / Two errors occurred in computing surface area. / More than two errors were evident in the surface area calculations.
