Instructional Segment 1
Objects move and collide.

The fossil record documents the existence, diversity, extinction, and change of life forms throughout Earth’s history.

Newton’s Laws explain the forces and motions of objects on Earth and in space.

Velocity and mass determine the results of collisions between objects.

Instructional Segment 2
Noncontact forces influence phenomena locally and in the solar system.

Models explain lunar phases and eclipses of the Sun and Moon.

Gravity plays the major role in determining motions with the solar system and galaxies. 
Gravitational and electromagnetic fields are the basis of noncontact forces.

Changing the arrangement of objects in a system affects the potential energy stored in that system.

Instructional Segment 3
Evolution explains life's unity and diversity.

Mutations in genes affect organisms’ structures and functions.

Evidence from fossils, anatomy, and embryos support the theory of biological evolution.

Natural selection is the main mechanism that leads to evolution of species that are adapted to their environment.
The geologic time scale organizes Earth’s 4.6 billion year history based on evidence from rock layers. Chemical reactions make new substances.

Mass is conserved in physical changes and chemical reactions.
NOTE: May be incorrect.
Instructional Segment 4
Human activities help sustain biodiversity and ecosystem services in a changing world.
Changes to environments can affect probabilities of survival and reproduction of individual organisms, which can result in significant changes to populations and species.

Annual cycles in the amount of sunlight absorbed cause Earth’s seasons. 

Increases in human population and per-capita consumption impact Earth’s systems.
Waves are reflected, absorbed, or transmitted through various materials.

Wave-based digital technologies provide very reliable ways to encode and transmit information.
