Project Study Guide The Water Cycle Vocabulary: 1. Evaporation-liquid water is heated and changes to a gas. 2. Condensation- gas is cooled and changes back to a liquid. 3. Precipitation- a liquid or a solid falls to the ground. 4. Water Cycle- the movement of water from the ground to the air and back to the ground by evaporation, precipitation and condensation. 5. Water Sources- rivers, reservoirs, wells. Concepts: 1. The sun is the source of energy for the water cycle. 2. Our water supply is limited on Earth; therefore, we need to keep it clean. 3. The same amount of water has always been on Earth. 4. During the water cycle a liquid is heated and changed to a gas. The gas is cooled and changes back…show more content…
All living things need water to survive. Living cells are mostly water. Cycles in Nature Vocabulary: 1. Cycle- a repeated pattern. 2. Phase- one of the stages or changes in the moon as it moves around the Earth. 3. Revolution- the movement of Earth one time around the sun; to move around a fixed point or object. 4. Rotation- the turning of Earth on its axis; spinning. Concepts: 1. Seasons, day and night, phases of the moon, tides and life cycles are cycles that occur in nature. 2. The Earth’s rotation on its axis causes day and night. 3. One complete rotation occurs every 24 hours. 4. The Earth takes 365 days, or one year to revolve around the sun. 5. The seasons change because the Earth’s axis (imaginary line through the middle of the Earth from north to south) is tilted towards or away from the sun. 6. The tides follow a pattern of 2 high and 2 low tides every 24 hours. 7. The pattern of the tides is caused by the moon’s gravitational pull. 8. It takes 28 days for the moon to orbit the Earth, or go through one complete cycle. 9. Plants have a life cycle in which a seed grows into a new plant and forms more seeds. * Seed- Sprout Seedling Plant 10. Animals have a life
