SCIENCE LESSON IN GRADE III QUARTER 1 THINGS IN THE SURROUNDINGS AND THEIR IMPORTANCE A LESSON IN SCIENCE III You depend on each other and need the nonliving things in your home, like food, water, air, and furniture. Living things need nonliving things to survive. Without food, water, and air, living things die. Sunlight, shelter, and soil are also important f or living things. Living things need nonliving things to survive. Without food, water, and air, living things die. Sunlight, shelter, and soil are also important for living things. Living things meet their needs from living and nonliving things in ecosystems. Plants are important in ecosystems. They are food for many animals. Plants use water from the soil, carbon dioxide from the air, and energy from sunlight to make their own food. This is called photosynthesis. Plants give off oxygen when they make food. Animals need oxygen to breathe, and they give off carbon dioxide. Can you see how plants and animals need each other? Animals and plants depend on each other for other things, too. Birds, lizards, and insects build their homes in trees. Deer and small animals sleep and hide in thick brush. Some plants need animals to spread their seeds. What role does weather play in plant growth? Soil is important in ecosystems too. It is made from broken-down stones and materials like dead leaves, twigs, and roots. There are living things in soil. Bacteria, fungi, insects, and worms all live here. In many ways soil might be considered an ecosystem. It’s a place that has living and nonliving things which need and use each other. Ecosystems are always changing. Living things are born; they grow and die too. Nonliving things can break down. They can also build up. The living fungus in this photo is breaking down the dead wood in a log. Things like wind, fi re, and disease can cause big changes. Do ecosystems ever stay the same? Sand particles Silt particles Clay particles Loam Farms are ecosystems. Farmers work with crops, animals, soils, and the weather to grow our food. Some animals on farms are visitors from nearby forest or water ecosystems. Can you think of any that might like to eat this alfalfa? There are four textures of soil: sand, clay, silt, and loam. Sand texture is like the sand on a beach. Clay texture is like modeling clay. Silt is in between sand and clay. Loam is a soil made up of equal amounts of sand, silt, and clay. Silt is often found along river banks. Loam makes good farm fi elds and gardens. Notice how water moves diff erently through each soil texture. The forest is an ecosystem. Forests are full of living and nonliving things that depend on each other. Trees, ferns, and shrubs grow in Ponds, lakes, streams, wetlands, and oceans are ecosystems too. They are water ecosystems. They are home to things like algae, insects, fi sh, and turtles. These living things depend on nonliving things like stones, sunlight, and soil, as well as water. All living things in ecosystems are part of

2. OBJECTIVES:
Relate the importance of surroundings to people
and other living things (S3ES-IVc-d-2).
• distinguish the characteristics of each

• create concept map showing the importance
and ways to protect the things in the
surroundings; and
• value the importance of the things in the
surroundings.

23. There are many things that
surround us. Earth has materials
that we all need to survive.
There are things that come
directly from the earth, such as
soil, water, and minerals.

24. Landforms

25. volcano
“bulkan”

26. A volcano is a mountain that has
opening. It ejects magma,
volcanic ashes, and gases.
Volcanic eruptions can cause a
serious impact on living things,
the economy, and the
environment.

27. Example of
Volcanoes in
the
Philippines

28. Mayon Volcano

29. Taal Volcano

30. mountain
“bundok”

31. Mountains are higher than their
surrounding areas. They have
steep slopes and they serve as
habitats for different kinds of
wild animals. Mountains serve as
protection from harsh weather
conditions.

32. Example of
Mountains
in the
Philippines

33. Mount Apo

35. hills
“burol”

36. Hills are lower and
less steep than
mountains.

37. Example of
Hills in the
Philippines

38. Chocolate Hills

39. plain
“kapatagan”

40. Plains are the low, flat areas of
Earth. Some plains are created
from the soil that are carried
by floods over time or by
flowing lava after a volcanic
eruption.

41. Example of
Plains in
the
Philippines

43. valley
“lambak”

44. Valleys are flatlands between
hills and mountains. Some
valleys have water forms in
them. The soil in valleys is
fertile which make them
excellent farmlands.

45. Example of
Valleys in
the
Philippines

46. Cagayan Valley

47. plateau
“talampas”

48. Plateaus are high flatlands.
They are separated from the
other areas by steep slopes.
Many towns, cities, and
agricultural areas are located
on plateaus.

49. Example of
Plateau in
the
Philippines

50. Bukidnon

51. island
“pulo”

52. An island is a landform
surrounded by water.

53. Example of
Islands in
the
Philippines

54. Bukidnon

55. Uses of Soil

56. 1. Plants grow in soil.
2. Soil is also habitat for many
animals.
3. People use sand, gravel, and
clay for the construction of
houses, buildings, and railroads.

57. 4. Clay is used to make different
pots for plants, earthen jars for
storing water, and even
decorative jars for home use.

58. Caring for and
Conservation
of Soil

59. • Plant more trees.
• Do not throw garbage
everywhere.

60. Water Forms

61. river
“ilog”

62. Rivers are flowing bodies
of water. They are in
between lands and are
usually crossed by bridges.
River water comes from a
highland.

63. Example of
River in the
Philippines

64. Bugang River

65. Cagayan River

Seas in the
Philippines

69. Sibuyan Sea

70. South China Sea

71. ground
water

72. Groundwater may be found
everywhere. It may be found in
a deep or shallow part of the
ground. It is a safe source of
household and drinking water. It
is considered the cleanest water.

73. spring
“bukal”

74. Spring is a water that
comes from the
underground and return to
the surface.

75. Example of
Springs in
the
Philippines

78. lake
“lawa”

79. Lake is a body of water
that surrounded by land.
The water of the lake
comes from a river. It is
usually bigger than a
pond.

80. Example of
Lakes in the
Philippines

81. Taal Lake

83. pond
“palatubigan”

water that is smaller than a
lake. It may contain
shallow water with aquatic
plants and animals.

87. waterfall
“talon”

88. Waterfall is a water that
rushes down a
mountain and falls off.

89. Example of
Waterfalls
in the
Philippines

91. Maria
Christina Falls

“karagatan”

93. Ocean is a body of
saltwater. It is the largest
body of water. Most of the
water that covers the
earth’s surface is ocean
water.

95. Uses of Water

96. 1. Clean water is used for
drinking, cleaning, cooking and
even taking a bath.
2. Big bodies of water are used
for transporting people and
goods from one place to
another.

97. 3. Other water forms are used
for recreational purposes such as
boating and swimming.
4. Water may also be used in
industries for making products
and in watering farms.

98. 5. Many water forms are habitat
for fishes, other sea animals and
plants.
