Students explore the life cycles of a variety of common materials from the acquisition of raw materials through to the end of the product’s useful life. After learning about the basic building blocks of matter, elements, and the periodic table, students model the structures of several common compounds. Moving from the atomic level to the material level, students investigate what conservation of matter means in light of the product life cycle and how this can affect manufacturing decisions. In the culminating set of investigations, students draw upon their understanding of the atomic nature and conservation of matter to determine a way to improve the life cycle of a computer circuit board.
Students will be able to..
Define problems that arise when properties of materials may act as constraints relating to product design.
Develop and use models representing atoms, elements, molecules, and compounds. (System and system models)
Plan and carry out investigations to demonstrate conservation of matter. (Stability and Change)
Analyze and interpret data to identify the properties of materials and determine the material’s best use based on its properties. (Structure and function)
Use mathematics and computational thinking to calculate and compare masses of reactants and products as evidence of the law of conservation of matter.
Design solutions to minimize the potential negative consequences that result from a given recent technological advance. (e.g., disposal of cell phones, etc.)
Engage in argument from evidence to engage in a debate about the best way to dispose of hazardous materials
Obtain, evaluate, and communicate information about how the characteristic properties of substances are used to group them.
