Lesson: Spaghetti Bridge Challenge
This lesson sets out to test students' ability to construct a bridge that can support a predetermined weight. Students will need:
-Half of the contents of a spaghetti box (per group of 2-3 students)
-Elmer's glue dispenser (1 per group)
Day 1: Students should be given ample time to design a bridge and draw blueprints.
Days 2-3 or 4: Students should construct their bridge
Final day: Test the bridges
Tips for implementing lesson:
Designate an area for students to dry their bridges. Two large folding tables in the back of the room should be good.
Groups of 2-3 students is recommended
On test day have several desks separated at 40cm ready to go. Then have several groups set up their bridges to test them. This will speed the testing process up.
Have a garbage can ready to place the broken bridges in
Have rubrics ready to go
Do not allow students to trade or borrow glue; these are the constraints on the challenge. Constraints are meant to add a degree of difficulty to promote their trouble-shooting skill development. Struggling to solve the challenge is part of the learning process in engineering and design activities!
Cleaning up glue can take some time, so allocate enough time at the end of class to wipe down desks and sweep up spaghetti pieces
