Stop the Stretching
Source Institutions
Learners work with plastic sheeting, masking tape, and string to design the perfect material for plastic chair webbing, and then construct their webbing.

Critical Load
Source Institutions
In this activity, learners explore the concepts of structural engineering and how to measure the critical load, or the maximum weight a structure can bear.

Sticky Structures
Source Institutions
In this engineering/design/arts and crafts activity, learners design and build "platforms" or "bridges" that can hold weight, and test which glue makes the strongest structure.

The Squeeze is On
Source Institutions
Each group of learners uses everyday materials, such as paper, toothpicks, and tape to design and construct a structure intended to support the weight of a cinder block for 30 seconds.
