Q2 Week 10
Day 1:

2. Let’s find out!
Where do we find the world’s tropical rainforest? Can you name any?

3. Let’s Watch and Learn!
Video 1: Video 2:
Take Note: Write down important details as you watch the video clip.

4. Let’s share!
1. Write something about a tropical rainforest based on your understanding 2. Share and discuss your answers to the class. 3. After the sharing, give some feedbacks.

5. Let’s work it together! Group 1 Group 2 Group 3 Group 4
Create a tropical rainforest layer/
canopy using
pupils themselves or use assorted
construction
papers (follow
the procedures
given in the
activity sheet)
Role play: pupils will show how
the Earth’s
exposure
to the Sun
affects the
temperature in
the tropical
rainforest.
(follow the
procedures
given in the a
ctivity sheet)
Create a creature: Let the pupils
design their own
rainforest creatures using potatoes as their body.
Then allow them to explain how
their creatures
adapt in the
tropical rainforest.
Create a tropical
rainforest rap using the physical
conditions as lyrics.

6. Big Concept!
Most rain forests are structured in four layers: emergent, canopy, understory, and forest floor. Each layer has unique characteristics based on differing levels of water, sunlight, and air circulation. While each layer is distinct, they exist in an interdependent system: processes and species in one layer influence those in another. 

7. Big Concept!
Emergent Layer The top layer of the rain forest is the emergent layer. Here, trees as tall as 60 meters (200 feet) dominate the skyline. Foliage is often sparse on tree trunks, but spreads wide as the trees reach the sunny upper layer, where they photosynthesize the sun’s rays. Small, waxy leaves help trees in the emergent layer retain water during long droughts or dry seasons. Lightweight seeds are carried away from the parent plant by strong winds

8. Big Concept!
Canopy Layer Beneath the emergent layer is the canopy, a deep layer of vegetationroughly 6 meters (20 feet) thick. The canopy’s dense network of leaves and branches forms a roof over the two remaining layers. The canopy blocks winds, rainfall, and sunlight, creating a humid, still, and dark environment below. Trees have adapted to this damp environment by producing glossy leaves with pointed tips that repel water.

9. Big Concept!
Understory Layer (Shrub layer) Located several meters below the canopy, the understory is an even darker, stiller, and more humid environment. Plants here, such as palms and philodendrons, are much shorter and have larger leaves than plants that dominate the canopy. Understory plants’ large leaves catch the minimal sunlight reaching beyond the dense canopy.

10. Big Concept!
Forest Floor Layer (Ground layer) The forest floor is the darkest of all rain forest layers, making it extremely difficult for plants to grow. Leaves that fall to the forest floor decay quickly.

11. Let’s evaluate!
DIRECTION: Write the letter that corresponds to your answer.
Which area has probably most rain? Why?
Forest, because there are plenty of trees that
will release moisture to the atmosphere.
b. Not forest, because there are no wild animals.
c. Grassy place because their roots help hold
water.
d. Bare areas, because it is good for planting
root crops.

12. Let’s evaluate!
DIRECTION: Write the letter that corresponds to your answer.
2. Where are the tallest trees in the rainforest found? a. In the emergent layer b. In the canopy c. In the shrub layer d. In the ground floor

13. Let’s evaluate!
DIRECTION: Write the letter that corresponds to your answer.
3. What is one reason why the rainforests are so important? a. They give out carbon dioxide. b. They provide us with oil. c. They are a source of medicines. d. They give warmth to living things.

14. Let’s evaluate!
DIRECTION: Write the letter that corresponds to your answer.
4. Why are vines creeping up to tall trees? a. To get food. b. To absorb oxygen. c. To receive a little amount of sunlight. d. To escape from the rainforest.

15. Let’s evaluate!
DIRECTION: Write the letter that corresponds to your answer.
5. What prevents plant growth beneath the trees in a thick forest?
A small amount of water reaches the ground under the trees.
b. The roots of the trees make it difficult for
plants to grow.
c. The trees limit the amount of sunlight that can
reach the ground.
d. The temperature of the soil under the trees
does not allow plants to grow.
