Score: / 10

🌳 Terrestrial

Live primarily on land (forests, grasslands, deserts, underground). Breathe with lungs and walk with legs/paws.

🌊 Aquatic

Live in water (saltwater oceans, coral reefs, freshwater rivers/lakes). Breathe with gills or surface blowholes.

🪶 Aerial

Fly in air and nest high in trees. Possess lightweight hollow bones, wings (feathers/membranes), and keen vision.

🐸 Amphibious

Live both in water and on land. Have moist skin for breathing, lay eggs in water, and thrive near wetlands.

Part A: Habitat Match Write the correct habitat classification for each description (Terrestrial, Aquatic, Aerial, or Amphibious).

1 Animals that live in rivers, ponds, seas, and oceans, using fins or flippers to swim:

2 Animals that live on soil, mountains, prairies, and forests, walking on paws or hooves:

3 Animals that spend much of their active time flying in the sky or gliding between tree canopies:

4 Creatures capable of surviving both on dry land and in water bodies like marshes:

5 Underground burrowers like earthworms and mole crickets that tunnel through moist soil:

6 Coral reef fish that take in dissolved oxygen through gills and never leave the saltwater:

Part B: Habitat Riddles Read each clue carefully. Name the specific Animal and its Natural Habitat.

Habitat Riddle #1: The Gentle Ocean Giant

“I am the world's largest fish! You can visit me in Donsol, Sorsogon. I filter plankton through my gills in the warm sea.”

Animal & Habitat:

Habitat Riddle #2: The Forest Canopy Climber

“I have huge nocturnal eyes and can rotate my head almost 180 degrees. I cling to tree branches in the Bohol rainforest.”

Animal & Habitat:

Habitat Riddle #3: The Walking Fish

“I hop across muddy mangrove roots when the tide is low, breathing air through my skin and moist gill chambers!”

Animal & Habitat:

Habitat Riddle #4: The Ship of the Dunes

“I store fat in my humps, have wide padded hooves that don't sink in loose sand, and can travel for days without drinking water.”

Part C: Animal Habitat Table Identify the Primary Classification (Terrestrial, Aquatic, Aerial, Amphibious) and specific habitat for each animal.

Animal	Primary Category	Specific Habitat & Key Survival Trait
1. Bangus (Milkfish)		Saltwater & Brackish lagoons; streamlined body with caudal swimming fin.
2. Carabao (Water Buffalo)		Grasslands & rice fields; hooves for walking, wallows in mud to cool off.
3. Philippine Eagle		Tropical rainforest canopy; 7-foot wingspan and sharp talons for air hunting.
4. Green Sea Turtle (Pawikan)		Marine coral reefs & open ocean; paddle-shaped flippers for swimming.
5. Philippine Bullfrog		Wetland ponds & muddy banks; webbed feet and moist skin for gas exchange.
6. Fruit Bat (Flying Fox)		Night skies & forest trees; membranous winged hands for powered flight.
7. Dromedary Camel		Arid desert sands; fat-storing humps and wide non-sinking padded hooves.
8. Garden Earthworm		Underground topsoil; streamlined burrowing segments and moist skin.

Part D: Ecosystem Explorer Match each group of native animals to the Philippine ecosystem they naturally inhabit.

🪸 1. Tubbataha Coral Reef

Clownfish, sea anemones, giant clams, sea turtles, and colorful parrotfish navigating vibrant underwater coral gardens.

Ecosystem Type:

🌲 2. Sierra Madre Mountain Rainforest

Philippine eagles, flying lemurs (kagwang), wild boars, cloud rats, and hornbills dwelling in towering dipterocarp trees.

Ecosystem Type:

🦀 3. Coastal Mangrove Swamp (Bakawan)

Mudskippers, fiddler crabs, mangrove snappers, and herons thriving along intertidal muddy shorelines where rivers meet the sea.

Ecosystem Type:

🌾 4. Central Luzon Agricultural Plains

Carabaos, maya birds, field mice, dragonflies, and harmless garden garter snakes living across wide open agricultural farmlands.

Part E: Fact or Myth Circle TRUE if the habitat science statement is correct, or FALSE if it is incorrect.

1

Whales and dolphins are classified as fish because they spend their entire lives swimming in ocean water.

TRUE FALSE

2

Earthworms live in moist underground soil because direct sunlight dries out their skin and prevents them from breathing.

TRUE FALSE

3

All birds are exclusively aerial animals that spend most of their daily time flying in the sky.

TRUE FALSE

4

Amphibians like frogs require freshwater ponds or damp wetlands to lay their jelly-coated eggs safely.

TRUE FALSE

5

Animals with thick blubber and dense fur coats are naturally adapted to survive best in hot, sunny deserts.

TRUE FALSE

Part F: Habitat Protector Match each positive human conservation action to the endangered animal habitat it directly saves.

🌱

Planting mangrove propagules along sea coastlines

Protects:

🚫

Banning dynamite & cyanide fishing on reefs

Protects:

🪓

Enforcing strict anti-illegal logging forest laws

Protects:

🚯

Cleaning single-use plastics from riverbanks

Protects:

🌾

Part G: Science Inquiry & Critical Reflection 2 Points

Explain in 2 to 3 complete sentences: Why are wild animals (like the Philippine Eagle or Butanding whale shark) unable to simply adapt and survive if their natural forest or coral reef habitat is completely cut down or heavily polluted?

Diagnostic Performance Benchmarking (Total Score: 30 Points)

★ Master Level (27–30)

90% – 100% Score

Exemplary mastery of animal habitats, ecosystem classifications, and environmental adaptations. Ready for Grade 5 ecology.

✓ Proficient (22–26)

73% – 89% Score

Solid conceptual grasp of primary habitats. Review marine mammals (whales/dolphins vs fish) in Part E.

▲ Needs Reinforcement (<22)

Below 73% Score

Struggles with differentiating terrestrial vs amphibious animals. Recommended for a targeted PERSONALIZED diagnostic review.

Pedagogical Insight for Tutors & Parents: Grade 4 students frequently classify whales and dolphins as "fish" because they swim in the ocean. Clarify that habitat alone does not determine animal group: whales have lungs, give live birth, and nurse their young with milk, making them marine mammals! Emphasize the interdependence between animal adaptations and their habitat.
