Coliseum Model by Butch Tumlos I. Objectives: - to be able to use Conic Sections in practical applications for architectural structures II. Description: Coliseum Model - Height: 8.2 cm - Total Circumference: 48 pie cm - Total Area: 576 pie cm2 III. Materials: - 2 illustration boards (1/2 in each size), 4 long folders, glue gel/glue gun, scissors, cutter, mechanical pencil, eraser, compass, ruler, protractor, and poster color(silver & green) IV. Procedure: 1. Draw the sketch of the top view of the Coliseum Model on each of the 2 illustration boards. Cut the first illustration board following all the lines being drawn on it. Reserve the second illustration board for procedure #8. 2. Using the 2 long folders cut the following: a. 4 strips; h=2 cm, l=27 cm b. 4 strips; h=2 cm, l=30 cm c. 4 strips; h=2 cm, l=33 cm d. 4 strips; h=2 cm, l=18 cm e. 4 strips; h=2 cm, l=21 cm 3. Connect the first 4 strips (a) then attach to the innermost circle drawn on the base of the coliseum. 4. Connect the second 4 strips (b) then attach to the second innermost circle drawn on the base of the coliseum. Continue the same procedure for the other batches of strips (c), (d), & (e) to be able to assemble the model. 5. Assemble the entrance based from the sketch. 6. Draw 23 stands using the remains of the first illustration board, then cut. 7. Place the stands in their respective positions. 8. Make the sides of the coliseum using the 2 remaining long folders, then place it in its position. 9. Then place the initially formed model on the second illustration board following the lines followed the lines drawn. 10. Paint the model using the silver poster color and the background using the green poster color. V. Applications/Uses: To show how accurate measurements can be used in developing architectural models, which can be eventually used as basis for the construction of actual architectural structures. In this model, the use of parabola and circles contribute to the exactness of the dimensions. VI.
