Term | Definition |
---|---|
Claim | A statement that answers your question |
Evidence | The scientific data or details to support your claim |
Reasoning | Explains "how" or "why" the evidence supports the claim |
Models | Examples drawn to show science concepts using labels, colors, and explanations |
Data | Facts and information collected (usually numbers shown in a graph or table) |
Variable | Anything that can be changed in an experiment |
Kinetic Energy | Moving energy |
Thermal Energy | Heat energy |
Molecule | The smallest unit of a substance |
Unit | Quanity/ amount |
Analyze | Look over/study something carefully |
Natural Hazards | An event that impacts human environment (Ex. tornado, hurricane, blizzard, earthquake) |
Air Pressure | The weight of air molecules pressing down on Earth |
Air Mass | A body of air that extends several miles wide and high with the same conditions of temperature and humidity |
Warm Front | Weather at this front includes steady showers followed by warm, wet and humid air; red half circle line pointing to the direction it is moving |
Cold Front | Weather at this front includes brief heavy thunderstorms, possibly strong winds (tornadoes/ blizzards) followed by cooler and drier air; blue triangle line pointing to the direction it is moving |
Stationary Front | When a cold front and warm front meet with no movement for severals days; red and blue line |
Occluded Front | When a warm air mass is trapped in between 2 cold air masses; purple triangle and half circle line |
High Pressure System | Causes clear, sunny days/ brings happy weather |
Low Pressure System | Causes cloudy rainy days/brings lousy weather |
Precipitation | Water that falls from the sky in the form of rain, snow, sleet or hail |
Water Cycle | The movement of water within the Earth and atmosphere where liquid water evaporates into water vapor, condenses to form clouds, then precipitates back to Earth through rain and snow |
Density | Amount of mass per volume; how tightly (or loosely) packed particles are; more dense sinks, less dense floats/ rises |
Convection | The process of transferring heat through air or liquid currents |
