LESSON 2: THE WATER PARTS OF THE EARTH DO AND LEARN A map is a picture of the Earth. A map is flat, not round like a globe. The biggest water part is called ocean. There are 5 oceans namely: Arctic Ocean, Atlantic Ocean, Pacific Ocean, Indian Ocean and Antartic Ocean. READ AND LEARN The ocean is the biggest body of salt water. The salt water of the ocean near the land is the sea. The sea is the smallest part of the ocean. The beach is the land part where sea water flows. Rivers are water parts of the Earth. Rivers begins in mountains. The rainwaters come together. The rainwaters get bigger and bigger. The rainwaters flow down the mountain sides. They flow through the land. They go out to the sea. Rivers are named by the land where they flow. A waterfall is part of a river. The water falls down from a high place. Our biggest waterfall is Maria Cristina Falls in Mindanao. People find waterfalls beautiful. Many enjoyed the rapids of Pagsanjan Falls, Laguna. A spring is rainwater stored underground. The water comes out on the hole in a ground. The water flows out. Many people use the spring water in drinking and cooking. Springs are usually found in thick wooded places. A resort has been built in Hidden Valley in AlamiĂąos, Laguna. Lakes are water parts of the Earth. A lake is a very low place filled with water. It is surrounded by land. The water in the lakes comes from rain. Some rivers flow into a lake. Our biggest lake is Laguna de Bay. LEARN THE SCIENCE WORD waterfall- water flows vertically coming from a high place ocean- biggest body of salt water spring-water coming out from the underground and flows into a body of water sea- a body of water which is part of the ocean nearest land lake- body of fresh water surrounded by land river- permanent natural flow of water larger than a stream YOUNG JI INTERNATIONAL SCHOOL/COLLEGE

REMEMBER
There are several kinds of water parts of earth. These water parts maybe made of fresh or salt water. These water parts maybe different from each other in some ways. The Earth is made up of more water than land.

LESSON 3: TAKING CARE OF THE EARTH DO AND LEARN The earth is home to all people. It is our only home. We have to take care of the Earth. READ AND LEARN How shall we take care of the earth? How do you take care of your own home. Keep it clean Throw garbage properly Rivers are not garbage cans. No waste must be thrown into rivers. Rivers “die” if they are used as garbage cans. The water stops flowing. Trees around die too. The rivers smells bad. Marine life dies. Fish, shrimps, crabs and seashells die. The water YOUNG JI INTERNATIONAL SCHOOL/COLLEGE

smells bad. There will be no food for the people if the rivers die. Garbage thrown everywhere make the earth dirty. Black smoke from cars makes the Earth dirty. Smoke from factories makes the earth dirty. All of our bad doings make our earth dirty. How can we help clean the earth? Plant! Plant at home. Plant in school. Join planting activities on roadsides. The leaves of the plants take in the gas given off by cars. The plants use the gas. The more plants they are, the more gas are taken in. the more gas taken in, the cleaner the Earth becomes. Save water! Use a basin in washing dishes. Close the faucet when not in use. Use a glass when brushing your teeth. Use a sprinkler in watering plants. Fix leaks. Avoid playing and wasting water. LEARN THE SCIENCE WORD marine life-animals and plants living in water space-area outside of the Earth REMEMBER The Earth is our only home. We must care of it.

REMEMBER The sun shines and the wind is calm on a fine weather day. The wind blows strong and there is much rain on a rainy weather. The wind is strong, there is thunder and lightning, rain pours on a stormy weather. The kind of weather affects our activities of the day.
