| Term | Definition |
|---|---|
| Water | A molecule made of two hydrogen atoms and one oxygen atom. It is essential for life and has unique properties. |
| Capillary action | The ability of water to move upward through narrow spaces. It happens because of cohesion and adhesion |
| Cohesion | Water molecules sticking to other water molecules. This creates surface tension. |
| Adhesion | Water molecules sticking to other surfaces. It helps water climb materials like plant stems. |
| Polarity | Water has a positive and negative end, like a magnet. This lets it dissolve many substances. |
| Transfer | Moving something from one place to another. Energy, heat, or matter can all be transferred. |
| Energy | The ability to do work or cause change. It exists in many forms like heat, light, or motion. |
| Atmosphere | The layer of gases around Earth. It protects life and helps regulate temperature. |
| Hydrosphere | All the water on Earth, including oceans, lakes, rivers, and groundwater. |
| Climate | The long-term weather patterns of a region. It includes temperature, rainfall, and wind. |
| Convection | Heat transfer through the movement of fluids like air or water. Warm materials rise and cool materials sink. |
| Freeze | When a liquid turns into a solid. Water freezes at 0°C (32°F). |
| Dissolve | When a substance breaks apart and mixes evenly into a liquid. The result is a solution. |
| Specific Heat Capacity | The amount of heat needed to raise the temperature of a substance. Water has a high specific heat capacity, so it warms slowly. |
| Solid | A state of matter with a fixed shape and volume. |
| Liquid | A state of matter with a set volume but no fixed shape. |
| Gas | A state of matter with no fixed shape or volume. |
| Solute | The substance being dissolved in a solution. |
| Solvent | The substance that does the dissolving. Water is the most common solvent. |
| Solution | A mixture where the solute is evenly dissolved in the solvent. |
| Surface Tension | The tight “skin” on the surface of water caused by cohesion. |
| Water Cycle | The continuous movement of water through evaporation, condensation, and precipitation. |
| Kevin Scale | A temperature scale starting at absolute zero. It is used mainly in science. |
| Absolute Scale | A temperature scale that begins at absolute zero, where no heat energy remains. |
| Universal Solvent | A nickname for water because it dissolves more substances than any other liquid. |
| Homogenous solution | A mixture that is the same throughout, with evenly spread particles. |
| Examples Of Heterogenous Solutions | Sand and water, oil and water, and cereal in milk. |
| Example Of Cohesion | Water droplets sticking together on a window. |
| Example Of Adhesion | Water sticking to the sides of a glass. |
| Example Of Surface Tension | An insect standing on top of a pond. |
| Example Of Capillary Action | Water climbing up a paper towel or up a plant’s stem. |
