These core ideas can be applied to explain and predict a wide variety of phenomena that occur in people’s everyday lives, such as the evaporation of a puddle of water, the transmission of sound, the digital storage and transmission of information, the tarnishing of metals, and photosynthesis. Matter can be understood in terms of the types of atoms present and the interactions both between and within them.
Within matter, atoms and their constituents are constantly in motion.
Modern communication, information, and imaging technologies are applications of scientific understandings of light and sound and their interactions with matter.
They are pervasive in our lives today and are also critical tools without which much of modern science could not be done.
The three core ideas are PS1: Matter and Its Interactions, PS2: Motion and Stability: Forces and Interactions, and PS3: Energy.
We also introduce a fourth core idea: PS4: Waves and Their Applications in Technologies for Information Transfer—which introduces students to the ways in which advances in the physical sciences during the 20th century underlie all sophisticated technologies available today.
