Popsicle Stick Bridge Building Popsicle Stick Bridge Building Arch or beam bridge to be made out of popsicle sticks and white glue. The bridge must span distance of 14 inches. The bridge must be able withstand a minimum of 25lbs weight without failing. Each group must use no more than 200 popsicle sticks for the construction of their bridge.

Forces Acting on Structures:
	Level 1 (N/A)	Level 2 (N/A)	Level 3 (N/A)	Level 4 (N/A)
Appearance	Level 1 Struggled with (shapes, patterns, etc.) Work is sloppy throughout. Design is unattractive and/or plain. 0 pts	Level 2 Limited (shapes, patterns, etc.) Design and use of glue is messy at times. Some visual appeal. glue use..messy 5 pts	Level 3 Overall, an attractive bridge (shapes, patterns, etc.) Tidy work most of the time. Visually appealing. 10pts	Level 4 Extremely aesthetic in design (shapes, patterns, colour, etc.) All constuction is clean and attractive. Visually appealing. 15 pts
Structure	Level 1 Basic beam bridge (no real design). Does not span a gap of 14in (unstable or incomplete). Does not meets the dimension requirement. Did not maximize use of materials. 0 pts	Level 2 Beam or arch bridge with limited creative design. Spans a gap of 14in, but remains unstable or incomplete in some way. Meets the dimension requirements. Limited use of materials 10 pts	Level 3 Beam or arch bridge designed with good creativity. Spans a gap of 14in, is complete and stable. Meets the dimension.Good use of materials. 20 pts	Level 4 Arch bridge designed with excellent creativity. Spans a gap of 14in complete and stable. Meets the dimension requirements. Excellent use of materials. 25 pts
Weight Held	Level 1 Failed at 15 pounds or lower. 0 pts	Level 2 Failed between 16-21 pounds of weight. 5 pts	Level 3 Failed between 22-27 pounds of weight. 10 pts	Level 4 Did not fail with 27 pounds of weight. 15 pts
Design & Reflection	Level 1 Bridge design does not match the design of the blueprint and changes were not explained. 0 pts	Level 2 Bridge design somewhat matches the design of the blueprint. If any changes were made during building, they were explained a little upon reflection. 10 pts	Level 3 Bridge blueprint mostly matches the design of the finished product. If any changes were made during building, they were sufficiently explained upon reflection. 15 pts	Level 4 Bridge blueprint matches the design of the finished product. If any changes were made during building, they were thoroughly explained upon reflection. 20 pts
