Bridge Building Straw Bridge Building All bridges must be made out of straws, Popsicle sticks and tape and spans 30-50 cm across the gap. Rubric Code: RX7A75W By HHAPOT Ready to use Public Rubric Subject: Science Type: Project Grade Levels: K-5, 6-8

Forces Acting on Structures: Straw Bridge
	Level 1 (N/A)	Level 2 (N/A)	Level 3 (N/A)	Level 4 (N/A)
Appearance	Level 1 Not aesthetically pleasing (shapes, patterns, etc.) Work is sloppy throughout. Design is unattractive and/or plain.	Level 2 Limited aesthetics (shapes, patterns,, etc.) Design and use of tape is messy at times. Some visual appeal.	Level 3 Overall, an attractive bridge (shapes, patterns, etc.) Tidy work most of the time. Visually appealing.	Level 4 Extremely aesthetic in design (shapes, patterns, etc.) All constuction is clean and attractive Visually appealing.
Structure	Level 1 Bridge with no real design. Does not span a gap of 30-50 centimeters (unstable or incomplete). Did not maximize use of materials. Design doesn't show triangles. The bridge doesn't hold any weight.	Level 2 Bridge with limited creative design.<BR> <BR> Spans a gap of 30-50 centimeters, but remains unstable or incomplete in some way. Limited use of materials. Design has few triangles and squares. The bridges hold some weight.	Level 3 Bridge designed with good creativity. Spans a gap of 30-50 centimeters, is complete and stable. Good use of materials. The design has triangles or squares. The bridge holds weight steadily.	Level 4 Bridge designed with excellent creativity. Spans a gap of more than 30-50 centimeters is complete and stable. Excellent use of materials. The design has triangles and squares. The bridge holds weight for more than 5 minutes.
Diagrams	Level 1 The diagrams are not precise, accurate and/or labelled.	Level 2 The diagrams are somewhat precise, accurate and/or labelled.	Level 3 The diagrams are generally precise, accurate and/or labelled.	Level 4 The diagrams are precise, accurate and well-labelled.
Explanation	Level 1 Does not describe the forces acting on the bridge Limited description of why you designed your bridge the way you did. No explanation as to how it will support the test weight.	Level 2 Describes some the forces acting on the bridge A brief description of why you designed your bridge the way you did. Limited explanation as to how it will support the test weight.	Level 3 Describes the forces acting on the bridge Good description of why you designed your bridge the way you did. Clear explanation as to how it will support the test weight.	Level 4 Thoroughly describes the forces acting on the bridge Clearly describes why you designed your bridge the way you did. Expert explanation as to how it will support the test weight.
