COTERC Grade 2 - Educational Resource

  1. 1. Welcome to the rainforest Today, we are going to go deep inside the rainforest and learn about some of the amazing animals that live there.
  2. 2. Animals such as…
  3. 3. Animals such as… Mammals
  4. 4. Animals such as… Mammals Amphibians
  5. 5. Animals such as… Birds Mammals Amphibians
  6. 6. Animals such as… Reptiles Birds Mammals Amphibians
  7. 7. Animals such as… Insects Reptiles Birds Mammals Amphibians
  8. 8. As you can guess, rainforests can be very wet places. A rainforest may receive from 400 to 1000 centimetres of rain each year. 1000 cm By comparison, Toronto receives 500 cm about 75 centimetres of rain each year. 75 cm 0 cm 0 cm
  9. 9. Rainforests are also warm places. The temperature stays between 25 – 30 Celsius all year. Now you know that rainforests are wet and warm. The rainforest makes a wonderful home for many different kinds of animals because they all need water to survive. It is also easier for animals to survive where it is warm all year.
  10. 10. Rainforests can be divided into three layers. The top layer is made up of the tops of all the rainforest trees. This layer is called the canopy. This part of the rainforest receives the most amount of sunlight and rain. Trees and plants need this sunlight and water to grow.
  11. 11. The layer below the canopy is called the understorey Notice that there is not a lot of light here. The leaves in the canopy stop most of the sunlight. Many animals call the understorey their home. In fact, this is where you can find the most number of insects in the rainforest.
  12. 12. If we move even further below the canopy and below the understorey, we will reach the forest floor. Very few plants actually grow at this level because it is too dark. The forest floor is mostly covered in dead leaves. Can you see an animal in this picture?
  13. 13. This bird is called a Night Hawk and it blends in very well with the dead leaves on the forest floor. Many animals in the rainforest blend in with their homes to help them hide and stay safe. Are you ready to meet some of them?
  14. 14. Most of the animals we find in the rainforest are insects. The insects in this picture are weaver ants. See how they hold onto each other to make a living bridge between the leaves.
  15. 15. There are many different types of insects, but they all have characteristics that show us they are insects. All insects have six legs. Let’s count them.
  16. 16. 6 5 1 2 4 3
  17. 17. 3. Abdomen 2. Thorax 1. Head Insects also have three main body segments.
  18. 18. Katydids are insects that are related to grasshoppers. Can you see the katydid in this picture?
  19. 19. Katydids are well known for their camouflage. They can look like sticks, flowers, and leaves. This one looks like a leaf.
  20. 20. Here is another animal that lives on a leaf. This one is not an insect though. It only has four legs. The red-eyed leaf frog is an amphibian and amphibians have different characteristics than insects.
  21. 21. All amphibians have moist skin. This means that the skin is always just a little bit wet. You know that the rainforest is a wet place, so it is a great place for animals that like to have wet skin.
  22. 22. Amphibians also have a backbone. Animals with backbones are called vertebrates. Insects do not have a backbone. Animals without a backbone are called invertebrates.
  23. 23. This poison dart frog is a very colourful amphibian. Most animals use their colour to camouflage but the poison dart frog is different.
  24. 24. Poison dart frogs use their bright colours to give a warning. The bright red colour tells animals to stop and leave the frog alone. If they eat it, the frog’s poisonous skin will make them sick.
  25. 25. Some people that live in the rainforest use the poison from this frog’s skin. They put the poison on their hunting darts. When they shoot the dart into an animal, the poison quickly kills it.
  26. 26. This snake is called a boa constrictor and it is a reptile. Reptiles have dry scales on their skin. Another characteristic of reptiles is that they do not make heat inside their body.
  27. 27. Mammals, like the jaguar, make heat inside their body just like you. Animals that make their own heat are called endothermic. Endo means inside and thermic means heat. Endothermic animals make heat inside their bodies.
  28. 28. Reptiles, insects and amphibians, like this frog, are ectothermic. Ecto means outside and thermic means heat. Ectothermic animals get heat from outside their bodies. They do not make their own body heat.
  29. 29. Many different types of birds make the rainforest their home. This little hummingbird flies from flower to flower drinking sweet nectar with its tongue. You already know that insects have six legs, amphibians have moist skin, and reptiles are scaly. Can you think of one characteristic of birds?
  30. 30. You can probably think of many characteristics. Birds have beaks… feathers… and wings. Birds, like mammals, also make heat inside their body. They are endothermic.
  31. 31. The jaguar is a mammal. You are a mammal too. Remember that mammals make their own body heat. They are endothermic. Mammals also have fur or hair all over their body.
  32. 32. The eyelash viper is a type of snake found in the rainforest. When it is born, this snake looks just like its parents. Do all animals look just like their parents when they are born?
  33. 33. Actually, most animals do not look like their parents when they are born. Just look at this little ant larva. It does not look anything like the ant that is carrying it. Insects and amphibians usually look very different when compared to their parents.
  34. 34. Mammals, birds, and reptiles are not like insects and amphibians. When mammals, birds, and reptiles are born they look a lot like their parents. This bat had two eyes, two ears, a mouth, two wings, and two feet just like its mother and father.
  35. 35. Now we can review all the characteristics of the animals we have seen
  36. 36. Now we can review all the characteristics of the animals we have seen Mammals •Backbone •Fur or Hair •Endothermic
  37. 37. Now we can review all the characteristics of the animals we have seen Mammals Amphibians •Backbone •Backbone •Fur or Hair •No scales, hair, •Endothermic or feathers •Ectothermic
  38. 38. Now we can review all the characteristics of the animals we have seen Birds •Backbone •Feathers, beaks, and wings •Endothermic Mammals Amphibians •Backbone •Backbone •Fur or Hair •No scales, hair, •Endothermic or feathers •Ectothermic
  39. 39. Now we can review all the characteristics of the animals we have seen Birds Reptiles •Backbone •Backbone •Feathers, beaks, •Dry scales and wings •Ectothermic •Endothermic Mammals Amphibians •Backbone •Backbone •Fur or Hair •No scales, hair, •Endothermic or feathers •Ectothermic

  41. 41. You have learned a lot about rainforests and the animals that live there. The rainforest is an important home for millions of species of plants and animals and they are an important part of our Earth.
  42. 42. But rainforests are disappearing and so are the animals that live there.
  43. 43. The trees are being cut down to be used for wood. One tree is a home for hundreds of animals. Destroying one tree is like destroying a whole neighborhood in your city.
  44. 44. Farmers cut down the forest to raise cattle and grow crops.
  45. 45. The roots of trees and plants are like hands that hold the soil together. When the forest is cut down,…
  46. 46. …the rain washes away the soil. This is called erosion. After the rain is gone and the sun comes out,…
  47. 47. …the ground dries up and very few plants can grow.
  48. 48. We need to protect the rainforest. •It provides a home for millions of plants and animals. •Rainforest plants produce oxygen so we can breathe. •The rainforest fruits provide food so we can eat. •Some plants can be used for medicine to keep us healthy.
  49. 49. Although rainforests cover only a small part of the world, far away from our homes, they have an effect on all of us.
  50. 50. Once rainforests are destroyed, they will be gone forever. You can do something about it. Your home provides many chances to help the rainforest: • Reduce, reuse, and recycle • Use products from the rainforest without destroying it. • Encourage local and national organizations, like COTERC to help save the rainforest.
