Title: Rainforests


1
Rainforests
  • An outline for upper elementary students

2
Rainforest Facts
  • There are two types of Rainforests Temperate
    and Tropical
  • Tropical Rainforests
  • These types are found in 85 countries around the
    world
  • They are located in the area around the Equator,
    where temperatures stay above 80 degrees
  • Temperate Rainforests
  • The soil in these rainforests have a lot more
    nutrients in it.
  • Temperate rainforests arent as common as
    Tropical.

3
More Facts about Rainforests
  • Many of the animals found in rainforests are
    found no where else on Earth.
  • Some humans also live in rainforests, today,
    there are under 200,000 people living in the
    rainforests.
  • Rainforests cover about 2 of the Earths
    surface, but over half the plant and animals on
    Earth live in the rainforest.
  • Nearly half of the worlds plants, animals, and
    microorganisms will be destroyed or threatened in
    the next 25 years due to deforestation.
  • There are about 3,000 fruits found in the
    rainforests.
  • About 2000 trees a minute are cut down in a
    rainforest.

The 3 layers of a rainforest
  • The Forest Floor
  • This layer has poor soil.
  • Most of the insects live in this layer.
  • The Understory
  • Many small scrubs and trees are found here.
  • Smaller animals (lemurs, tree kangaroos) live
    here as well.
  • The Canopy
  • Made up of the tops of trees.
  • Tropical birds, monkeys and apes are found here.

5
Birds in the rainforest
  • In a small area in Costa Rica, there are over 500
    different kinds of birds!
  • Most of the birds that live in the rainforest are
    big, colorful and loud.

6
Other animals in the rainforest
  • Monkeys, gorillas and chimpanzees are some
    animals that are commonly found in rainforests.
  • There are also many different kinds of frogs,
    insects and cats that live there.

7
Plants in the rainforest
  • Most tropical plants are exotic and very
    beautiful.
  • Canopy trees are common in rainforests, and
    many of them can stand up to 100 feet tall!
  • Many foods come from rainforest plants, such as
  • Pineapples
  • Bananas
  • Coconut
  • Chocolate!

8
Types of plants in the rainforest
  • Lianes
  • The roots of these plants are on the forest
    floor, but they rely on trees for support.
  • Epiphytes
  • These also get their nutrients from other sources
    but are grounded with roots. Where the nutrients
    come from depends on the species of plant.
  • Stranglers
  • These start out as Epiphytes but eventually
    produce roots that wrap around the trees they
    live on.

9
Where are Rainforests located?
Rainforests are located in a band around the
Equator. This area is called the Tropics.
10
Why are rainforests important?
  • Plants in the forest create carbon dioxide, which
    helps keep the air we breathe clean.
  • The plants and animals in the rainforest provide
    us with food, fuel wood, shelter, jobs and
    medicine.

11
Deforestation
  • Thousands of rainforests are being cut down.
  • Every second, an area of rainforest the size of a
    football field is destroyed.
  • When the trees are cut down, it makes it easier
    for rain to wash away the land.
  • Without the trees and other plants, floods happen
    in the areas where there used to be trees.

12
Deforestation through the years
  • Scientists say the rate of deforestation will
    continue for the next 10 to 15 years, then there
    wont be enough forest left to sustain the
    cutting.

13
What happens when forests are destroyed?
  • Song birds, which help farmers by eating insects,
    cant migrate to Tropical Rainforests
  • The people who live in the forests lose their
    homes, culture, and sometimes their lives.
  • Some plants that may have medicines in them and
    arent discovered yet, will never be discovered.
  • The climate will change because the lack of trees
    will cause the wind to change directions.
  • Thousands of species of plants and animals will
    be destroyed forever.
  • Floods and drought will become more common
    because the rainforests cant soak up the water
    if they dont exist.

14
A cool experiment
  • To show how the cutting down of rainforests
    really effects the soil, here is an experiment to
    try
  • Put a mound of dry soil in each of two shallow
    containers (like pie pans). Place a sponge
    securely on top of one mound of soil. Slowly pour
    water from a measuring cup onto the sponge until
    the sponge is completely soaked and the soil is
    partly wet too. Pour exactly the same amount of
    water on the soil in the other container. What
    happens to the soil in each container when you
    pour the water? Which soil dries out first?

15
Things YOU can do
  • Use less paper- most of the paper you write on
    comes from trees that were in rain-forests.
  • Use less gas and plastic- These things come from
    oil, which is found in rainforests
  • Eat less red meat- After the rainforests are
    slashed and burned, the land is used for pastures
    for cows.
  • Fundraise for the rainforest- raising money is
    important to help save the rainforest. Find an
    organization to donate to.
  • Write a letter- writing letters to presidents of
    companies that destroy rainforests.
  • Educate yourself and others- learn about why they
    are so important

Some fun Rainforest games
  • Memory Game
  • Rainforest Word Search
