1. What kinds of materials do people use to build structures?

       There are two sorts of building materials: natural substances like stones, rocks, wood, sand and clay and man-made products such as bricks, cement, foam, glas, plastics and metals.

2. Why are some materials better for projects than others?

       Some materials are much better because of economical and ecological reasons. If the materials are especially repairable, with long lifespan and the increased levels of fire-safety, they are better for projects.

1. How do shapes relate to engineering?

       Shapes are used in most fields of engineering. Engineers use them to understand how to design and build everything.

2. What different shapes do engineers use to construct buildings

       Much earlier they used only a few basic shapes such as circle, rectangle and triangle. Nowadays they use all geometric shapes to construct buildings.
