Matter
The three primary states of matter
(Solid, Liquid, Gas)
Potential Energy
Energy stored in an object due to its position or height
The force that pulls all objects toward the center of the Earth
(Gravity)
The process plants use to turn sunlight into food
(Photosynthesis)
The layer of the Earth located directly below the crust.
(Mantle)
Physical vs. Chemical changes
(e.g., melting ice vs. burning wood)
Sound
This type of energy travels in longitudinal waves and requires a medium to move
A force that opposes motion between two surfaces that are touching
(Friction)
Newton's First Law is also known as the Law of ______
(Inertia)
The planet in our solar system known for its prominent rings
(Saturn)
Subatomic particles
(Protons, Neutrons, and Electrons)

(Chemical Energy)
A push or a pull on an object
Forces
This occurs when the Moon passes between the Sun and Earth
(Solar Eclipse)
A biological community of interacting organisms and their physical environment.
(What is an ecosystem?)
A change in matter that does not create a new substance, like melting ice
Physical Change
The law stating that energy cannot be created or destroyed, only transformed
Law of Conservation of Energy
The rate at which an object changes its position; speed in a specific direction.
(What is velocity?)
Animals that eat both plants and meat
Omnivore
The variable in an experiment that is intentionally changed by the scientist
(Independent Variable)
Negatively charged subatomic particles that orbit the nucleus
