There are many connections to science concepts and some to design and build challenges as well.

This lesson, from Engage New York, has students investigating:the forces involved in constructing a stone archadd and subtract vectors given in magnitude and direction formsolving problems that can be represented by vectorsThis lesson has teacher and studnet versions in both PDF and Word form. In this lesson, students will investigate the forces involved in constructing a stone arch utilizing the web app GeoGebra. This investigation also use a PBS Learning/NOVA site to enhance the learning so the students have context. There are structured questions for opening and discussion of possible impacts on stone arches. Students will work on GeoGebra to find resultant vectors. Then there is a structed exploratory activity for students to calculate magnitude and direction of force vectors. This lesson also provides an optional Exit Ticket to determine if students have achieved the learning goals of the lesson.
