Properties of Water
What about water molecules makes water have the ability to dissolve other substances?
What are the three states of water found in the water cycle?
What are solid, liquid, and gas?
What is the difference between weathering and erosion?
What is weathering is the breaking down of rocks, while erosion is the movement of those materials?
Why is careful management of water resources important?
What is to ensure sustainable use and protect ecosystems?
What is the state of water at 0 degrees Celsius?
What is solid (ice)?
Describe the two forces that contribute to cohesion and adhesion in water.
What are hydrogen bonds and attraction to other molecules?
What do you call the process of water changing from a liquid to a gas?
What is evaporation?
Provide an example of physical weathering.
What is ice wedging?
Name one way to conserve water at home.
What is fixing leaks or using water-efficient appliances?
Describe what happens to water molecules when they heat up.
What is they move faster and spread apart, changing from liquid to gas?
Identify an example of cohesion or an example of adhesion in everyday life.
What is water forming droplets (cohesion) and water climbing up a straw (adhesion)?
What are the four (4) forms of precipitation?
What is when water falls from clouds as rain, snow, sleet, or hail?
How does acidified water affect building materials like concrete?
What is it can cause chemical weathering and deterioration of the materials?
Explain the role of water in power generation.
What is water can be used to generate hydroelectric power?
How does temperature affect the transition between solid, liquid, and gas states of water?
What is increasing temperature can cause melting and evaporation?
Explain why ice floats on water.
What is because ice is less dense than liquid water?
What role does the sun play in the water cycle?
What is the sun provides energy for evaporation and drives the cycle?
Explain how weathering contributes to the geography of Virginia.
What is weathering shapes landscapes and forms soil, affecting land use?
How does pollution affect water resources?
What is it can contaminate water supplies and harm wildlife?
Compare the properties of water in solid, liquid, and gas states.
What is solid has a fixed shape, liquid takes the shape of its container, and gas fills the entire space?
How does thermal energy affect the state of water?
What is adding thermal energy can turn ice into liquid water and then into vapor?
Compare the average winter temperatures in western Virginia to those along the Chesapeake Bay.
What is western Virginia tends to be colder than areas along the coast due to higher elevation/no large bodies of water?
Model the process of freezing water impacting rock structures.
What is freezing water can expand in cracks, causing rocks to break apart?
Plan an investigation to demonstrate the importance of clean water for human health.
What is testing local water sources for contaminants?
Explain how thermal energy changes the state of water during the water cycle.
What is as thermal energy increases, water transitions from solid to liquid to gas and vice versa?
