What kind of tower can support a ball with a set number of straws?

In G4 English class, students were divided into three to four groups to create a straw tower as a study to express their own opinions, listen to others, and summarize their ideas.

The purpose of this activity is not to see if the tower will be successful or not, but rather to “exchange and summarize opinions.” All of the groups got excited when they demonstrated the tower they had built by placing a ball on it!
