What makes a bridge strong? What features bring stability to bridges? Shapes? What materials do you have around the house that you could make your bridge out of?
Build your bridge! How can you combine/attach materials? Test your bridge. What modifications can you make? Bonus Challenge: Can something travel over it? A toy car? A remote-controlled car?
