This integrated project should be taught at the end of the school year during both the science and social studies blocks. It is a culminating, integrated science and social studies project.

KEY STANDARD(S) Science (Each standard is a student performance expectation that includes all three dimensions of science.) Standard 2.3.2 Construct an explanation showing how the properties of materials influence their intended use and function. Examples could include using wood as a building material because it is lightweight and strong or the use of concrete, steel, or cotton due to their unique properties. (PS1.A) Standard 2.3.3 Develop and use a model to describe how an object, made of a small set of pieces, can be disassembled and reshaped into a new object with a different function. Emphasize that a great variety of objects can be built from a small set of pieces. Examples of pieces could include wooden blocks or building bricks.
