Назви та деталі стандартів можуть залишатися англійською в неангломовних інтерфейсах.
Newton's third law and collisions (MS-PS2-1)
How two colliding objects push back on each other with equal and opposite force.
Core
Force, mass, and motion (MS-PS2-2)
How the total force on an object and its mass determine how its motion changes.
Core
Electric and magnetic force strength (MS-PS2-3)
What makes an electric or magnetic force stronger or weaker.
Core
Gravity between objects (MS-PS2-4)
Gravitational pull is always attractive and depends on the mass of the objects.
Core
Fields without contact (MS-PS2-5)
Objects can push or pull on each other without touching, through a field.
Core
Kinetic energy (MS-PS3-1)
How an object's kinetic energy depends on its mass and its speed.
Core
Stored (potential) energy (MS-PS3-2)
How the arrangement of objects changes how much energy is stored between them.
Core
Controlling heat transfer (MS-PS3-3)
Designing something that either traps heat in or lets heat escape faster.
Extension
Energy transfer between materials (MS-PS3-4)
How much energy moves between materials depends on what they're made of, how much there is, and how their temperature changes.
Core
Energy in, energy out (MS-PS3-5)
A change in an object's kinetic energy means energy moved into or out of it.
Core
Wave amplitude and energy (MS-PS4-1)
How the size (amplitude) of a wave relates to how much energy it carries.
Core
Waves meeting materials (MS-PS4-2)
What happens when a wave is reflected, absorbed, or passes through different materials.
