Although no charge or fee is required for using TeachEngineering curricular materials in your classroom, the lessons and activities often require material supplies. The expendable cost is the estimated cost of supplies needed for each group of students involved in the activity. Most curricular materials in TeachEngineering are hierarchically organized; i.

Some activities or lessons, however, were developed to stand alone, and hence, they might not conform to this strict hierarchy. Related Curriculum shows how the document you are currently viewing fits into this hierarchy of curricular materials. Typical truss bridge components. Civil engineers design buildings, bridges and towers using basic shapes such as triangles and squares. To make sure the structures are stable and safe, they design them to be able to withstand the anticipated loads without any deformation or bending.

They make precise and accurate specifications and measurements, and then double-check their plans by making estimates to verify that the calculations are reasonable. Through this activity, students come to see trusses from an engineering point of view—as unique compositions of polygon shapes that are further broken down into triangle shapes, which serve as the strongest and least deformable shapes.

Each TeachEngineering lesson or activity is correlated to one or more K science, technology, engineering or math STEM educational standards. In the ASN, standards are hierarchically structured: first by source; e. View aligned curriculum. Do you agree with this alignment?

## Sum Of Interior Angles In Triangles

Thanks for your feedback! Simulating a real-world civil engineering challenge, student teams are tasked to create strong and unique truss structures for a local bridge. They design to address project constraints, including the requirement to incorporate three different polygon shapes, and follow the steps of the engineering Working as engineering teams, students design and create model beam bridges using plastic drinking straws and tape as their construction materials.

Their goal is to build the strongest bridge with a truss pattern of their own design, while meeting the design criteria and constraints. First they review fundamental geometrical and trigonometric concepts. Then, they estimate the height of various objects by using simple trigonometry.

When you look at buildings and structures, what geometric shapes do you notice? What shapes do you see in bridges? What shapes make up a truss? After each of these questions, listen to student answers. Expect them to suggest shapes such as triangles, squares, pentagons, semicircles, arches, etc. As evidenced by all your answers, it is clear that the human-made structures around us are composed of many different shapes.

Today we are going to specifically talk about triangles and trusses. First, what is a truss? Listen to student definitions.
