In Straws We Truss

Topic: In Straws We Truss day 3
Time Duration: 2 hours and 30 minutes
Grades: 1st-6th

Building upon the lesson plan It takes Two to Topple, the lesson will use trusses to explain the concepts of tension and compression of structures from different forces. The applet will be used once again to provide a visual of structures. The applet will be used to show how forces affect different parts of the structures. The students will then build a structure using straight pin and straws. The structures will then be put under stress from marbles, and the students will have to explain why their structure failed.
