Local print media may be willing to donate extra newspapers. Paper chairs may hold more than it seems. All weights used must be weighed and recorded. Once again, have students collect items in advance, and have an abundant supply. The seat of the chair must be a minimum of 25 cm off the ground.
Students have one hour to complete the project.
Have students test the amount of weight their chairs will hold. Using combinations, add weight on seat in increments. If desired, place plywood on seat to help stack weight. Do not overload. The chair may be strong enough to seat a classmate or teacher.
