4. 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)?

5.

6. 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**

7. Start Planning and Building!! https://youtu.be/b9niGbPG qs8 https://youtu.be/b9niGbPG qs8 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.
