Depending on the size of your family, split up into two or three teams. Give each family a box of spaghetti and a bag of mini-marshmallows and have them construct a tower as tall as they can within 10 minutes. Whichever team gets the tallest tower within that 10 minute time-frame wins.
Debriefing: Discuss the teamwork that took place. What was your plan for the activity? What could you change to improve? How can you apply what you learned from this activity in your life or at home?
