|---|---|
| Salinity | The concentration of dissolved salts (usually sodium chloride) in a body of water. |
| Sand dune | A mound of sand that is deposited by the wind. |
| Satellite | An object that moves around Earth or some other object rather than falling onto it. |
| Scavenger | An organism that feeds on dead organic matter. |
| Sea floor spreading | Process by which new ocean floor is formed by lava erupting from a rift valley, pushing the existent floor outward from the rift. |
| Seasons | Changes in temperature and the length of day and night over the course of a year. |
| Sediment | Small pieces of rock, shell, and plant and animal matter that is moved and deposited by water, wind, or ice. |
| Sedimentary rock | Rock formed from sedimentation. |
| Sedimentation | The settling out of fragments of weathered rock or remains of living things that are carried and deposited by wind, water, or ice. |
| Selective breeding | Selection for specific traits imposed by humans, either deliberately or otherwise, upon wild or domesticated plants and animals. |
| Series circuit | An electric circuit in which the current passes through only one pathway. |
| Sexual reproduction | Mode of reproduction involving two parents, usually involving meiosis, gamete formation, and fertilization. |
| Solar energy | Energy from the Sun in the form of light and heat energy. |
| Solar System | The Sun with the group of celestial bodies that revolve around it. |
| Solid | The state in which a substance has a definite volume and shape and resists forces which try to change these. |
| Solubility | Ability of a substance to dissolve in another substance. |
| Solution | Mixture in which the molecules of one substance (solute) are dissolved in another substance (solvent). |
| Sound | Longitudinal wave produced by the vibration of a material. |
| Species | Organisms whose members are alike and successfully reproduce among themselves. |
| Speed | A scalar quantity that describes the change in position in a certain period of time (how fast something is moving). (Compare with velocity.) |
| Spring scale | Tool that is calibrated in Newton's and is used to measure the weight of an object. |
| Spring tide | Tide that occurs during the full and new moon phases in which the water level is higher than normal. |
| Standard unit | Inches, feet, yard, centimeters, meters, grams, ounces, pounds, Celsius degrees, Fahrenheit degrees, hours and minutes and non-standard units (i.e. paper clips). |
| Star | A natural, luminous, celestial body. |
| State of matter | The forms matter can take, as in liquid, solid, or gas. |
| Static electric charge | Potential energy in the form of a stationary electric charge. |
| Streak | The color of the powder that a mineral leaves when it is rubbed on a hard, rough surface. |
| Substance | Matter of a particular kind, or chemical makeup. |
| Sun | The star around which Earth and the other planets revolve that provides the main source of energy for living things on Earth. |
| Symbolic equation | Represents the relationship between two or more physical quantities expressed as symbols which represent the quantities. |
| System | A group of organs that work together to perform a specific job. |
| Temperature | The measure of the average energy of motion of the particles of a substance. |
| Thunderstorm | A storm with heavy rainfall, lightning, and thunder produced by cumulonimbus clouds formed when a cold front collides with a warm front. |
| Tide | The alternate rising and falling of the surface of the ocean and of water bodies connected with the ocean. It occurs twice a day and is caused by the gravitational attraction of the moon and the sun occurring unequally on different parts of the Earth. |
| Tilt | The angle between the Earth's axis and the line perpendicular to the plane of the Earth's orbit. |
| Tilting | Rock layers that move or shift at a slanted angle. |
| Tissue | A group of similar cells working together to perform a specific job. |
| Tornado | A destructive, whirling, funnel-shaped cloud that has extremely low air pressure. |
| Toxic | Harmful (adjective). (Compare with toxin - a harmful chemical produced by living things). |
| Trait | A characteristic which is passed on to offspring through heredity. |
| Transverse wave | A wave in which the vibration is moving in a direction perpendicular as that in which the wave is traveling. |
| Trend | The general drift, tendency, or direction of a set of data. |
| Tsunami | Large sea wave produced by submarine earth movement or volcanic eruption. |
| Unicellular | Organisms composed of one cell only. |
| Uplift | The raising of an area of land due to horizontal forces that slowly push on the area. |
