Water, Water, Everywhere?

Date Session # Activity Page # Warm Up: Designate 2-3 pages of your notebook for the 2nd Quarter table of contents. Draw the water cycle on page 1 of your notebook. Label the following processes of the water cycle: evaporation, condensation, precipitation, run off, percolation, infiltration, ground water movement, transpiration, recharge Date Session # Activity Page # 12/4-5 1 Water Cycle Review All the Water on Earth notes 2 Watershed Model – Analysis and Reflection Water on Earth Webquest 3 My Water Footprint (homework) Homework: Complete Conservation of Mass Study Guide (due 12/7 for Bday, 1/28 A Day) Visit the website: https://www.watercalculator.org/ Complete the survey and: Record your water footprint results on page 3 of your notebook. (you can print your results page and glue it to your notebook if you prefer.) Which water fact in the survey most surprised you? Test Review Session: Thursday 12/7 after school, Friday 12/8 before school Test 12/11 B Day, 12/12 A Day

8.E.1 Understand the hydrosphere and the impact of humans on local systems and the effects of the hydrosphere on humans. 8.E.1.1 Explain the structure of the hydrosphere including: • Water distribution on earth • Local river basins and water availability

TLW explain how water moves and is distributed by analyzing a modeling activity and completing a webquest.

The water cycle moves water around the planet 1. On the top half of page ___ in your notebook: Draw the water cycle.(include arrows showing direction and processes) Label the following processes of the water cycle: evaporation, condensation, precipitation, run off, percolation, infiltration, ground water movement, transpiration, recharge The water cycle moves water around the planet The energy that drives the cycle is provided by the sun.

What is the hydrosphere? All the Water On Earth Notes p2 What is the hydrosphere? The hydrosphere is ALL of the water on Earth Obvious Examples: Oceans, lakes, rivers, streams, creeks, seas, ponds, swamps/wetlands Not So Obvious Examples: clouds, underground reservoirs, glaciers, icecaps water in your body, water within plants

Salt Water Why is the ocean salty? Salt water is water that contains dissolved salts and other minerals Example – ocean, seas, Great Salt Lake Why is the ocean salty?

Fresh Water Fresh water is water that is not salty and has little or no taste, color, or smell Examples – river, lakes, glaciers, icebergs, icecaps, ground water

Water Distribution on Earth About how much of the Earth is covered by water? About 71%

Water Distribution on Earth: The Facts! 97% is salt water 3% is fresh water So, out of all the fresh water… 68% is frozen 30% is groundwater 2% is on the surface/free flowing

Water: Where Does It Come From, Where Does it Go? The Water Cycle

Evaporation When water changes from a liquid to a gas (water vapor) What makes the water evaporate?

Condensation When water changes from a gas (water vapor) to a liquid Give me an example of condensation…

Precipitation When water falls from clouds What are forms of precipitation?

Run-off/Accumulation When water moves from one location to another… and then gathers there What else can water do?

Infiltration Percolation Water soaking into the soil Percolation Water moving through the soil and accumulating in an aquifer (ground water)

Transpiration Water vapor coming from trees and plants

Water Drainage Patterns River Basins are areas of land that drain water into a large river. Watersheds are smaller areas of land that drain water into streams, lake or wetland. You may have several watersheds in a river basin. Divide = high ridge of land that determines the flow of water.

Questions???

Where do we find water? How does it move and stored? Crumple the paper on your desk, then un crumple the paper…you need high and low spots on the paper Trace where you think streams, rivers and lakes would be. Think about how water collects Mark the tops of ridges of the landscape Mark areas with exposed soil Put a few dots where you think you might find pesticides, agricultural waste, etc

How does water move? What does water move? Take a picture of your model before and after it rains. On page 3 of your notebook, describe: How the water moved In what type of areas did it accumulate? Where were different parts of the water cycle modeled? What was in the water.
