1 Classwork #1 Earth s Water Name: There are 100 boxes in the table below. 1. Color 97 of them blue. This is how much of the water is in the ocean. 2. Color 2 and ½ of the boxes green. This is water in glaciers and deep underground. 3. Color the last half of a box yellow. This is the fresh water in lakes, rivers and rainfall that we can use. Why is it important to take care of Earth s water?

2 Homework #1 Earth s Water Name: Read the clues about the different bodies of water. Write the name on the line next to it. Draw a line to the picture that matches the name. lake ice cap pond ocean river A large, still body of freshwater surrounded by land. A covering of ice over a large area. A large, moving body of freshwater. A small, shallow body of freshwater. A large body of salt water that covers most of the Earth.

3 Classwork #2 The Use of Maps Name: 1. What does this map show? 2. What types of bodies of water do you see? 3. Color the bodies of water blue. 4. Color the mountains brown. 5. Color the plains (flat areas) yellow.

4 6. What state do you live in? Color it red. 7. Write 2 facts you can learn from this map:

5 Homework #2 The Use of Maps Name: Map Makers People have been making maps for nearly 8,000 years. Cave drawings show how prehistoric people made maps of hunting grounds. Early explores used maps to show what they had found. Maps are important tools to show a route or path. A person who draws maps is called a cartographer. They use art, math and science to design maps. In the past, maps were drawn by hand. Only one map was made at a time. Today cartographers make maps using special computer software. Google Street and Google Earth are examples of modern maps. Many maps can be made at a time. Some maps are digital. They can be viewed on a computer, GPS or phone. 1. What does a cartographer do?

6 2. What do cartographers use to design maps? 3. How are today s maps different from early maps?

7 Classwork #3 Water s Changing Forms Name: Water can be found as a solid (as ice), a liquid (as water), or a gas (as water vapor). Water changes form because of changes in temperature. Color the thermometers to show the temperature water changes states. Water becomes a solid at 32 degrees Fahrenheit. Water stays liquid between 33 Fahrenheit and 211 degrees Fahrenheit. Water becomes a gas at 212 degrees Fahrenheit.

8 Why does Ice Float? Water becomes a solid when the temperature is 32 degrees Fahrenheit. The solid form of water is called ice. Ice takes up more space than liquid water. It floats on liquid because it is lighter. Imagine what would happen to fish if the ice did not float. It would sink to the bottom and freeze all of the animals that live in the water. What causes liquid water to change to ice? Complete the Cause and Effect Chart explaining your answer. Cause Effect

9 Homework #3 Water s Changing Forms Name: The Climate of Antarctica When you think of a desert you probably think of a place that is extremely hot and dry. The last place you would think of is Antarctica. But, Antarctica is the largest desert on the Earth! Antarctica is the coldest, windiest, and driest place on Earth. It gets less than 10cm of snow each year. This is because evaporation does not happen. It is too cold. Without evaporation, precipitation does not happen. When it does snow, the snow does not melt. It becomes ice and it builds up over many years. The average winter temperature is -58 degrees

10 Fahrenheit. This is colder than your freezer! Over 98% of Antarctica is covered by ice. Most of the ice is over 1 mile thick. This ice is about 70% of the Earth s fresh water. Emperor penguins and seals live in Antarctica. Scientists go there to study the climate, weather and wildlife. 1. What is the weather like in Antarctica? 2. Why is Antarctica such a dry place?

11 3. Why is the ice so thick in Antarctica? 4. What do scientists study in Antarctica? 5. What kind of animals live in Antarctica?

12 Classwork #4 The Water Cycle Name: How Old Is Water? The water you drink today is the made up of the same tiny particles that have been on the Earth for billions of years. We drink the same water that dinosaurs drank! How is this possible? Water is constantly being recycled in the water cycle. Number the statements below to show the correct order of the water cycle. When water vapor rises, it cools. This changes the water vapor from a gas back to a liquid. The sun heats the water. This turns the liquid into water vapor that rises into the air. Droplets of liquid gather together to form clouds. The rain, snow or hail falls back into rivers, oceans, or lakes. Some of the water seeps underground. When the water droplets get to heavy, they fall. Clouds drop water as rain, snow, or hail.

13 Cut out the pictures. Glue them in the correct order. Add arrows to show the movement of water. Label the stages: evaporation, condensation, precipitation.

14 Homework # 4 The Water Cycle Name: The Science Behind Frosty the Snowman Frosty the Snowman was a jolly, happy soul. He knew the sun was hot that day. So he said, Let s run and we ll have fun before I melt away. What would have happened to Frosty if he hadn t hurried on his way? Use what you know about the water cycle to create a comic strip showing what would happen to Frosty if he stayed in the village. Use colorful illustrations and captions to explain your ideas clearly.

16 Unit Review Name: Directions: Write the answer to each question in the box. Use the letters to solve the riddle. 1. Most of the world s water is 6 2. The average weather conditions for an area is 2 3. This heats up the Earth s water to cause evaporation 1 4. Ice is the name water Rivers, oceans and lakes are of water. 3

17 6. Rain, sleet, snow and hail are types of 4 7. A large body of salt water that covers most of the Earth 9 8. This forms when new layers of old and new snow are pressed together When water vapor changes into liquid water 5 Riddle: What goes up when the rain goes down?

18 CW & HW Answer Key Classwork #1: There is very little water that we can use. That is why we must take care of Earth s water. Homework #1 1. Lake 2. Ice cap 3. River 4. Pond 5. ocean Classwork #2: 1. The United States 2. Students should recognize rivers, lakes, and ocean 3. n/a 4. n/a 5. n/a 6. Answers will vary. 7. Answers will vary. Homework #2: 1. A cartographer draws maps. 2. Cartographers use art, math, science and computer software to design maps. 3. Early maps were drawn by hand and were made one at a time. Today s maps can be digital and many maps can be made at one time. Classwork #3: Thermometers should be neatly colored based on the temperature in the box. Cause: temperature is 32 degrees or below Effect: water changes to ice Homework #3: 1. The weather is cold, windy and dry. 2. It is dry because it is too cold for evaporation. Without evaporation, precipitation doesn t happen. 3. The ice is thick because it doesn t melt. It builds up over many years. 4. Scientists study Antarctica to learn about climate, weather, and wildlife. 5. Emperor Penguins and seals live in Antarctica. Classwork #4: Order: 2, 1, 3, 5, 4; Pictures should be labeled and ordered correctly.
