The students and teacher will go on a walk to look for and record the different types of structures they see in their community. Discussion will revolve around what a structure is, what makes it strong and stable, and what forces act on it. An investigation of structures can result from this shared experience. After gaining knowledge of structures, students will be asked to design and build a structure, such as a longhouse or a pioneer house, which is strong, stable, and can withstand forces applied to it.
