Bridge Building Parallel and Transversal lines

Link to Real-World

Jacksonville Florida Dames Point Bridge

A Local Favorite!1. Can you locate where the parallel lines and

transversals are?

2. How does bridge building relate to the geometry ‐we have been studying (Parallel lines cut by a transversal)?

• The student will explore angle relationships formed when lines are cut by a transversal in city planning models, specifically bridge building. • Grab computers for your research

• Complete Group Research on Bridges. Turn in your Student Research Worksheet. This is due at the end of the period. (20 pts)• Hint if you are having trouble finding information:

• Google the questions• Google the word Bridges• Find a video to watch

• When your group is done with the Research: Complete the Collaborative Work Rubric (20 points) Be Honest!!• Journal Writing Exit Slip

• Discuss the connection between building strong bridges and geometry. In particular, discuss the use of parallel lines and transversals. You can create a diagram to help with your explanation. (8 points)

**If you finish early, you and your group may begin building your bridge. Ask for a a copy of the Bridge Building Rubric from me**

Start Planning and Building!!• https://

youtu.be/b9niGbPGqs8• work in teams to design

and build your own bridge out of popsicle sticks and hot glue.

• Bridges must have a span of at least 18 inches and be able to hold a five pound weight.

• On Friday every student evaluate the effectiveness of their own bridge designs and those of other teams, and present their findings to the class.

Bridge Building Rubric (25 points)*To earn full credit in each area you must have

the following*• Plan – Plan is neat with clear measurements

and labeling for all components• Bridge Building Materials – Materials were

selected and modified appropriately• Construction-Care Taken – Great care was

taken in the construction process so that the bridge is neat, attractive and follows the submitted plans accurately.

• Function – Structure functions extraordinarily well, holding up under atypical stresses.

• Quality of work – Provides work of the highest quality that the group could produce.
