Vocabulary of Science Vocabulary - 5th Grade
| Term | Definition |
|---|---|
| Deposition | the process where materials are added to a landform or land mass, often through the movement of water, ice, or wind. |
| Weathering | the breaking down of rocks and minerals into smaller pieces by natural forces such as wind, water, and temperature changes. |
| Erosion | the process by which soil and rock are removed from one location and transported to another, often caused by water, wind, or ice. |
| Constructive | related to processes that build up landforms, such as the accumulation of sediment that creates new land. |
| Destructive | related to processes that break down or wear away landforms, such as erosion or natural disasters like earthquakes. |
| Physical Changes | changes that affect one or more physical properties of a substance without altering its chemical composition, such as melting or freezing. |
| Chemical Changes | changes that result in the formation of new chemical substances, typically involving a reaction that alters the chemical structure. |
| Electricity | a form of energy resulting from the flow of electric charge, often used to power devices and appliances. |
| Static Electricity | a stationary electric charge that builds up on the surface of objects, often created by friction. |
| Circuits | closed paths through which electric current flows, consisting of a power source, conductors, and devices that use electricity. |
| Insulator | a material that does not allow electricity or heat to pass through easily, used to protect us from electric shock. |
| Conductors | materials that allow electricity or heat to flow through them easily, such as metals. |
| Electromagnet | a type of magnet that is created by electric current flowing through a wire, which can be turned on and off. |
| Vertebrate | animals that have a backbone or spinal column, including mammals, birds, reptiles, amphibians, and fish. |
| Invertebrate | animals that do not have a backbone, such as insects, arachnids, and mollusks. |
| Vascular Plants | plants that have specialized tissues (xylem and phloem) for transporting water, nutrients, and food throughout the plant. |
| Nonvascular Plants | plants that do not have vascular tissues, relying on diffusion to move water and nutrients, such as mosses. |
| Cell Membrane | the protective outer layer of a cell that controls what enters and leaves the cell. |
| Cytoplasm | the jelly-like substance within a cell that holds the organelles and is where many cellular processes occur. |
| Nucleus | the control center of a cell that contains the cell's genetic material (DNA) and regulates cell activities. |
| Cell Wall | a rigid outer layer surrounding the cell membrane in plant cells, providing structure and support. |
| Chloroplast | organelles found in plant cells that convert sunlight into energy through photosynthesis. |
| Hypothesis | a testable prediction or educated guess about the outcome of an experiment or observation. |
| Learned Behavior | behaviors that are acquired through experience and practice rather than being innate or instinctual. |
| Jetty | a structure built out into the water to protect a harbor or coastline from erosion and to control water flow. |
| Fault | a crack or fracture in the Earth's surface where blocks of land have moved, often associated with earthquakes. |
| Delta | a landform created at the mouth of a river where it meets a body of water, formed by the deposition of sediment. |
