1) List Three Forms of Water. What Controls the Different Forms of Water?

1)  List three forms of water. What controls the different forms of water?

·  Three forms of water are solid, liquid, and gas.

·  Temperature controls the different forms of water.

2)  What temperature is water’s freezing point? (List both °F and °C)

·  32°F and 0°C

3)  What temperature is water’s boiling point? (List both °F and °C)

·  212°F and 100 °C

4)  Water is found in 3 places on the earth. Where are they and what is the percentage of them? Please give one example of each.

5)  What is water collection? Where is water collected? (Three places)

·  Water collection is where water is collected/gathered.

·  Examples are ocean, lake, river, pond, stream, etc.

6)  What is evaporation? Does evaporation only occur at the boiling point? Give example to support your idea. (Answers may vary)

·  Evaporation is the change of a substance from a liquid to a gas vapor.

·  Evaporation does NOT only occur at the boiling point.

·  Ponds dried out.

7)  What is condensation? Give an example of where condensation occurs in the water cycle. (Answers may vary)

·  Condensation is when water vapor cools, it changes back into a liquid.

·  Form a cloud/ Dew.

8)  What is precipitation? List 4 types of precipitation. Please also indicate at what temperature or around what temperature you will see this type of precipitation.

·  Precipitation is any from of water that falls from clouds.

·  The four types of precipitations are:

1)  Snow----32 degrees or below.

2)  Rain----32 degrees or above.

3)  Sleet----around 32 degrees.

4)  Hail---Could happen in any temperature. But “Ice” is formed below 32 degrees.

9)  On which kind of day would you expect the most evaporation from the surface of lake? (What kinds of weather or what temperature?)

·  When it is a sunny day or when the temperature is high, there would be most evaporation from the surface of lake.

10)  What source of energy evaporates the most water from Earth’s surface?

·  Sun

11)  Many Utah towns use water from wells for drinking. Can you explain how the water cycle gets water into the wells?

·  Water falls to the ground due to precipitation and sinks down through soil. It saturates pores or cracks in soils and rocks and gathered in aquifers from which groundwater can be extracted through a water well.

12)  What is A, B, C, ad D called?

·  A: Evaporation B: Condensation

·  C: Precipitation D: run-off

13)  Give three examples of what can happen to a drop of water after it falls as rain on the ground. (Answers may vary)

·  It evaporates.

·  It sinks through the ground.

·  It becomes run-off and flows to river/ocean/lake/pond and becomes a part of them.

14)  List five places where we can find water on the earth.

·  Ocean/stream/pond/lake/cloud/snow/icecaps/groundwater/air

15)  A teacher assigned her class to research how the water cycle affects a town’s water supply.

Student A found information on a City Water Management Internet Site.

Student B visited a waste water treatment plant.

Student C interviewed a town’s mayor.

Student D listened to a weather forecast.

Which student used the best source of information? Please explain WHY next to your answer.

A. Student A City Water Management has information on how water is used. When there is not enough water, it affects all people living in the city. (Talk to your child about the water shortage in California. That will help them understand the value of water)

B. Student B

C. Student C

D. Student D

16)  If you are a farmer, what rainfall do you want? Please explain WHY next to your answer.

·  Rainfall that slowly soaks into the soil. The plants will have time to absorb water to help them grow.

17)  Predict what might happen to a river when heavy rains soak the soil near it. The river will

A. sink

B. rise

C. freeze

D. not change

18)  A student wanted to locate a picture of the water cycle.

Which of the following would be the best source of information?

A. a mystery novel

B. a science textbook (Textbook will have a picture and information on water cycle)

C. an atlas

D. a thesaurus

19)  On a hot, sunny day, a student noticed a cold can of pop had water droplets running down the sides. Can you explain why droplets are found outside of the pop?

·  Because the surface of the pop is a lot cooler than the surrounding air. So the water vapor normally found in air condenses onto the surface of the pop. This is called condensation.

20)  What is run-off?

·  Precipitation that is not absorbed by the soil and flows over the surface of the ground.

21)  Dew is an example of evaporation, condensation, precipitation, or water collection? Why? Please explain to support your answer.

·  Dew is an example of condensation.

·  Dew is a type of condensation that occurs outdoors due to warmer air striking a colder surface.

22)  Why is it important to conserve water?

·  Answers may vary. Students need to know we need water in our everyday life. We can’t live without water.
