Split the group into teams of 4-5 people. Each team receives 20 spaghetti sticks and one paper tape. Instruct the teams to use the spaghetti and the paper tape to build the tallest structure. They have 18 minutes for this challenge.
While the teams work, observe how they work (do they have a strategy?, do they go directly into building?, how many times they try to build the structure?, how many ideas they try out?, etc.).
Once the time is up, reflect together with the teams on the process – what strategy they had, if they had one, how many ideas they had, how they tried out the ideas, how many times they built the structure, etc.
