Critical Load

Lesson Focus 
Lesson focuses on issues civil engineers face, including critical load and how to reinforce the design of a structure to hold more weight.

Age Levels:

8 - 14
  • Learn about civil engineering and the testing of building structure.
  • Learn about efficiency ratings and critical load.
  • Learn about teamwork and the engineering problem solving.
Lesson Activities 

Students learn about how to test structures for maximum load by designing prototypes of buildings out of cards. Topics examined include problem solving, teamwork, and the engineering design process. Students work first individually to build a structure, then combine materials in student teams to design the strongest structure, evaluate the load capacity and critical load, and discuss why the strongest design worked best. Students also learn about famous failed and successful building structures.
