Explain how engineers have improved existing technologies to increase their benefits, to decrease known risks, and to meet societal demands (artificial limbs, seatbelts, cell phones).
In this unit, students explore the science phenomena of Earth systems by studying aquifers, comparing the ability of different Earth materials to hold water. In this lesson, they build on that knowledge to engineer permeable pavement that can solve the problems of urban flooding and water pollution. This page showcases key components of this lesson.
In this unit, students explore the science phenomena of how energy is transferred in a circuit to do work. In this lesson, students figure out the phenomena affecting the left and right movement of an electric car. This page is a high-level extract of this lesson.
In this unit, students build on what they know about the science phenomena of energy transfer to focus on information transfer and how different technologies use patterns of sound, light, or numbers to transmit information. This page showcases key components of this lesson.
