In the space provided at the bottom of the page summarize what the unit is going to be about. Finally, look back over the statements and correct the ones you got wrong.

Agree Disagree

_____ _____ 1. The hydrologic cycle is another name for the water

cycle.

_____ _____ 2. Most of the water on Earth is found in the polar ice

caps.

_____ _____ 3. Our surface water flows into river basins from

watersheds.

_____ _____ 4. Local government determines the availability of

water in an area.

Overview

Water is one of the most common substances on Earth. It is circulated on Earth by a process known as the hydrologic, or water cycle. Most of the water on the Earth is found in the oceans. This is salty water. Most of our freshwater on Earth is found in the polar ice caps, glaciers, and aquifers. The availability of water changes with the local geography of an area and allows humans to use this water as a resource.

Name three ways you use water every day:

Lesson 1

Essential Question: Why is the hydrologic cycle important to life on earth?

The movement of water in and out of the atmosphere plays an important

role in determining climate patterns. Water evaporates from the surface of

the earth, rises and cools, condenses into rain or snow, and falls again to the

surface. The water falling on land collects in rivers and lakes, soil, and

porous rock; but most of it flows back into the oceans.

Sneak Peek

Copy each statement below. Place a “T” on the blank of true statements and a “O” on statements that are untrue in the “B” column. We will correct your answers at the end of the lesson in the “A” column.

B A

____ ____ 1. The hydrologic cycle moves through living and non-living parts

of the earth.

____ ____ 2. Evaporation is the change of a solid to a liquid.

____ ____ 3. Infiltration occurs underground.

____ ____ 4. Transpiration happens when water escapes from the roots of

plants.

Lesson Vocabulary

Use what you learned in the lesson scaffolding and the definitions below as a guide for writing your own definition of each word below.

1. condensation – occurs when water vapor cools and changes into liquid water droplets that form clouds in the atmosphere.

2. evaporation – is the change of a liquid water to a gas (water vapor).

3. hydrologic cycle – is a model for the storage and movement of water on earth.

4. infiltration - water that fills the cracks and pores in underground soil and rock layers.

5. precipitation – water that falls to the earth as rain, sleet, snow, or hail.

6. runoff – water that flows across land and collects in rivers, streams, and eventually the ocean.

7. transpiration – the release of water from the leaves of plants.

Notes Framework 1

Use what you read in Section 3 “The Water Cycle” on pages 32-35 to complete this framework with the important points of the reading assignment.

(1.) Water is naturally ________________________ through the water cycle.

The water cycle is the continuous process by which water moves through the ________________________ and __________________________ parts of the environment. The source of the energy that drives the water cycle is the ____________. (2.) The water cycle has no real _________________________ or _______________. When a water molecule absorbs enough heat energy to change state it _____________________________ and become _______________________________ ( 2 words). Even though this water came from the ocean, evaporation turns it into ____________________ water. This is because salt is a solid and cannot evaporate so it remains in the ocean. (3.) Large amounts of water evaporate from ______________________ and ___________________________(2 words). Small amounts evaporate from _________________________, _________________________, and your _____________________.

(4.) Plants draw in water from the soil through their ____________________. Eventually this water is given off through the leaves as water vapor in a process called ______________________________. (5.) Small amounts of water vapor are released by animals when they ______________________. (6.) Warm air carries water molecules high into the air where it is much colder. This causes the water molecule to ______________________. This is called condensation.

(7.) Eventually the drops of water in a cloud become too heavy and they fall back to earth in the form of _____________________, _______________________, _____________________, or ____________________. This is called _______________________________.

What Happened to It?

List four things that might happen to a drop of water once it falls to the earth as precipitation.

Page 2

The Hydrologic Cycle

Part I

Using the six terms on the Hydrologic Cycle graphic organizer in your notebook, draw an illustration of the cycle. You should have an illustration for each term. Use arrows to show that it is a circular cycle.

Part II

You will create a pie graph that shows the percentage of earth’s water found in each of the following locations:

a. oceans

b. icecaps & glaciers

c. groundwater

d. lakes

1. To calculate the number of degrees to be represented by each location you must multiply the decimal in the percentage column by 360 (the number of degrees in a circle). Your total degrees should equal 360.

2. Use the protractor you have been given to draw a 360° circle. Put a dot in the center of your circle and draw a radius from the center to the left side of the circle. You will start measuring here.

3. Your completed pie graph should have four parts. Label each part with the location and the percentage, not the number of degrees.

|Reservoir |Time Stored |% |° |

|oceans |forever |.94 | |

|icecaps & glaciers |20 years |.03 | |

|groundwater |100 years |.02 | |

|lakes |50 years |.01 | |

|Total |*** |1.00 | |

Part III

You are to create a bar graph of the least amount of time water is stored in the reservoir locations listed in the chart (not counting oceans – water stays there forever). Your finished bar graph should have three (3) bars.

Earth’s Water Distribution Investigation

Background Information

Earth is called the water planet because so much of the planet is covered by oceans. But all of the water on Earth is not salty. There are several reservoirs that contain freshwater, including the clouds in the sky.

Purpose: Where is most of the freshwater on Earth found?

Hypothesis: I think most of the freshwater is found

_____________________________________

Procedure:

1. Label the five cups on your tray:

a. deep groundwater

b. lakes & rivers

c. polar ice

d. shallow groundwater

e. water vapor

These are the reservoirs of freshwater. One of them holds more than the others.

2. The graduated cylinder on your tray contains 200 mL of water. This represents all of the water on the Earth.

3. Use the eyedropper to fill each cup with the amount of freshwater each reservoir contains. The remaining water in the graduated cylinder is ocean water. Use this information to draw a conclusion.

a. deep groundwater 11 mL

b. lakes & rivers 1 mL

c. polar ice 76 mL

d. shallow groundwater 12 mL

e. water vapor 1 mL

Conclusion: Based on the data I gathered in this investigation the reservoir that

holds the most fresh water is _________________________

My hypothesis was ________________________ .

*** complete the Going Further questions on the back***

SRA Cards

Most lessons have SRA cards that you are to complete. This is an INDIVIDUAL activity. Cards are to be done alone at the round table. You are to use the answer sheet you will be given. These answer sheets will not be returned until all students have finished the assigned cards. This will discourage students from sharing answers, a nice way of saying CHEATING!!!

There are two SRA cards for each topic. There is an “A” card, and a “B” card, and each card has 19 questions to complete. The “A” card is a little easier to understand than the “B” card. Your 7th grade EOG scores will be used to assign you to the cards you are to complete. If you do not score at least a 60% on a “B” card you must complete the “A” card for that topic. If you score less than 60% on an “A” card you will be required to go back and redo every one you missed.

Because reading comprehension is SO important, you actually receive TWO grades for these cards. First, you receive points for these cards as a part of your lesson grade. You also receive an SRA grade for each unit. You can track your SRA progress on the chart. Stars are used to show how well you are mastering these reading comprehension cards.

The SRA cards you need to complete for this lesson are given below:

How Water Holds Heat

Pretend that you and your family are spending the weekend at the beach in Wilmington. In the chart below predict how you think the sand and water will feel at the time of day indicated in the chart. Use qualitative terms like cool, warm, hot, etc.

|Time of Day |Sand |Water |

|early morning | | |

|afternoon | | |

|night | | |

From this data we can hypothesize that:

Hypothesis: sand heats up and cools down quickly but water heats up and

cools down slowly.

This activity will test that hypothesis. The data below was collected when a team heated sand and water for ten minutes and then allowed them to cool for ten minutes. Use this data to draw a conclusion about the heating and cooling of sand and water. Use the graph you have been given to graph the results of this lab.

Heating Cooling

|Time |Sand |Water |Time |Sand |Water |

|1 min. |20 |20 |1 min. |60 |35 |

|2 min. |25 |20 |2 min. |55 |35 |

|9 min. |60 |30 |9 min. |20 |25 |

|10 min. |65 |35 |10 min. |15 |20 |

Conclusion:

_____ Yes sand does heat and cool quickly; water heats and cools slowly.

_____ No sand does not heat and cool quickly; water doesn’t heats and cools

slowly.

Your 7th grade EOG scores will be used to assign you to the cards you are to complete. If you do not score at least a 60% on a “B” card you must complete the “A” card for that topic. If you score less than 60% on an “A” card you will be required to go back and redo every one you missed.

Because reading comprehension is SO important, you actually receive TWO grades for these cards. First, you receive points for these cards as a part of your lesson grade. You also receive an SRA grade for each unit. You can track your SRA progress on the chart. Stars are used to show how well you are mastering these reading comprehension cards.

The SRA cards you need to complete for this lesson are given below:

Lesson Summary

Every lesson you will complete this year has a two part summary. These activities tie the concepts together and should help you to answer the essential question, which is why we did the lesson in the first place! The first part of the summary is “Remembering Your ABC’s”. In this activity you have to recall information that you learned. The second part is the “Summarizing Questions”. These questions are designed to extend what you have learned by taking what you learned and asking you to draw conclusions about how one thing affected something else.

Complete the summarizing activities below.
