JiJi has left Chile and headed to the country of South Africa. Here JiJi found round homes called rondavels. Rondavels are made with materials such as mud, grass, and sand and resemble a cylinder with a cone-shaped roof. Unlike the standard rectangular shape of some houses, the round shape of rondavels allows high winds to go around the home without causing damage. The round shape also makes the home perfect for families and communities to sit in a circle, often around a warm fire.
Rondavels and similar round structures have been used as housing in many parts of the world. The simple and abundant building materials, ease of construction, and flexibility in size have made the rondavel popular, especially in Africa. The length of the radius determines the overall area of the rondavel. ,
- What is the largest possible radius of a rondavel that could fit in your classroom?
- Are there round buildings where you live?
TEACHER NOTE: Help students to discover the strength of the cylinder! Brainstorm places in their world that they see cylinders (parking garage columns, silos, electric poles, etc.) and then have them test a cylinder’s strength. Have students fold three sheets of paper to create different shaped columns: a cylinder, a square column and a triangle column. Have students test each column to see which one can hold the most notebooks or chapter books.
