Is it possible to construct a ceiling in a shape of a dome that expands over 20, 50, 80 feet in diameter without structural support within the radius of a circular space?

**OBJECTIVE: (part 1 of 2)**

To learn how domes are constructed using mathematical and geometric proportions and how they were used in the past.

**PRODUCT:**

By the end of the lesson, you will have the general knowledge of how domes are constructed through a means of mathematical equations through geometry. Math plays a critical role in architecture, especially in structure and design. After exploring the components that build a dome, you will then explore how domes were constructed in the past in places such as Rome, Italy.

A good definition in explaining what a dome is can be expressed from National Geographic:

*"A dome is a curved formation or structure. It is shaped like half of a sphere. Imagine cutting an orange in half, and placing it cut-side-down on a table. This is the shape of a dome, although most domes in nature are not perfectly rounded.*"

Calculate the volume of a sphere. Theoretically, you will calculate a sphere but then divide your answer by 2 to get the volume of a dome.

From Kahn Academy, watch and learn how to calculate the volume of a sphere. Remember, this is the calculation process of a sphere. To get the volume of a dome, simply divide the volume of a sphere by 2.

Calculate the Surface Area of a sphere. Remember that this is a sphere, to get the SURFACE AREA of a dome, simply divide your answer by half.

**Below are images of difference construction types of domes that can be built using a similar structure methodology. Look at each dome type, examine its structural components, and explain in a few short words, on a separate sheet of paper, how each dome might be constructed. At the end of this lesson, turn in your responses to your teacher. **
