Simple Snow Load Roof Model Demo: Which Roof Is Tops?

Type of Resource



When you walk or drive around your neighborhood, what do the roofs look like? What if you lived in an area with a different climate, how might that affect the style of roofs that you see? Through this introductory engineering activity, students explore the advantages of different roof shapes for different climates or situations. They observe and discuss what happens in a teacher demo when a "snow load" (sifted cups of flour) is placed on three model roof shapes.

Performance Expectations

K-2-ETS1-2   Develop a simple sketch, drawing, or physical model to illustrate how the shape of an object helps it function as needed to solve a given problem.

K-2-ETS1-3   Analyze data from tests of two objects designed to solve the same problem to compare the strengths and weaknesses of how each performs.
