ANIMALS and NATUREANIMALS and NATURE 4th gradeCANADA -ANIMALS AND NATUREWonders of Nature Introduction. The world is full of interesting animals. Some animals look strange or have special skills. Let's look at some of these wonders of nature. Archerfish. Archerfish spit water at bugs. The bugs fall into the water, where the archerfish catch and eat them. Trap-Door Spider. The trap-door spider lives in a tunnel in the ground. Its home has a hidden door made of silk and dirt. The spider hides in its tunnel to hunt. Beaver. Beavers chew through tree trunks. They make dams out of trees, mud, and stones. Chameleon. Chameleons change color to hide themselves. They even change color to show how they feel. Flying Dragon. Flying dragons have skin on their sides that opens like wings. They jump and glide from tree to tree. Leaf Insect. The body parts of leaf insects look just like leaves. These animals blend in well with real leaves on trees. Leaf-Rolling Weevil. The female leaf-rolling weevil rolls a leaf into a cone. She lays her eggs inside the cone. The leaf hides and protects her eggs. Praying Mantis. The praying mantis holds its front legs in a praying position. A mantis has five eyes to help it hunt for food. Mole. Moles dig tunnels to find and eat worms. These animals have tiny eyes, but they are not blind. Sea Dragon. Sea dragons are small fish. They look like ocean plants. Their leafy parts help them catch food and hide from enemies. Conclusion. Interesting animals come in many shapes and sizes. They are all wonders of nature.Nature Stinks! Stinky Nature. If you've ever smelled a skunk, you know it is not a nice odor. In fact, it's terrible! Did you know that both plants and animals can smell bad? Stinky plants smell bad to get helpful insects to come near. Stinky animals often smell bad to keep enemies away. Smelling bad helps both plants and animals stay alive. Stinky Furry Animals Skunks are well-known smelly animals. When enemies get close, skunks lift their tail and spray a stinky liquid. Striped polecats are cousins of skunks. They stink even worse! Lesser anteaters are at least four times as stinky as a skunk! They shoot a smelly liquid at their enemies. Opossums pretend to be dead if an enemy is near. They stay still and let out stinky green slime. Wolverines make a smelly liquid to keep other animals away from their home. They also pee on food they don't eat right away. The smell may help them find the food later. It may also keep other animals from eating it. Male musk oxen fight each other for females. Males use their stinky pee to tell other males to keep away. The pee sticks to their long belly hair and makes them smell terrible. Stinky Birds. The stinkbird mainly eats leaves. Food goes to its crop (the area under its throat) before the stomach. Tiny living things there break down the leaves. This way of eating makes the stinkbird smell terrible. Vultures eat animals that are dead and often rotten. When vultures are in danger, they throw up! The stuff they throw up is very smelly. Stinky Bugs. A type of beetle sprays a hot, stinky liquid from the back of its body. The spray can kill many enemies and burn people. Millipedes (MILL-ih-peedz) can't move fast. If an enemy bothers them, they curl up and give off a stinky liquid. Some millipedes can even shoot the smelly stuff! Other Stinky Animals. The common musk turtle has another namestinkpot! It smells bad when other animals disturb it. A stinky yellow liquid comes out of the back of its body. Musk turtle A female mink frog can lay 500 to 4,000 eggs at once. 14 A musk turtle can live forty to sixty years. Mink frog The mink frog also uses smell to stay safe from enemies. It smells like rotten onions. Good and Stinky. Being stinky helps many plants and animals stay alive. For plants, the bad smell brings helpful insects. For animals, the bad smell may keep enemies away or help in other ways. Stinky steam, spray, throw-up, slime, and pee all help living things stay alive.BIOMOLECULES CARBOHYDRATES Carbohydrates CARBOHYDRATES THE MOST ABUNDANT ORGANIC MOLECULES IN NATURE HYDRATE DE CARBON i.e. HYDRATE OF CARBON or Cn(H2O)n Main source of ENERGY Provide some STRUCTUR PRECURSORs of many organic compounds – FATS, AMINO ACIDS STORAGE FORM of ENERGY (Glycogen Animals) (Starch Plants) 3 CARBOHYDRATES SIMPLE MONOSACCHARIDE – GLUCOSE, FRUCTOSE, GALACTOSE DISACCHARIDE – MALTOSE, SUCROSE, LACTOSE COMPLEX POLYSACCHARIDE – STARCH, GLYCOGEN, CELLULOSE, lmnbh 4 MONOSACCHARIDES BASED ON No OF C ATOMS BASED ON FNCTIONAL GROUP TRIOSES (C3H6O3) –GLYCERALDEHYDE, ALDOSE-GLECEALDEHY, DIHYDROXYACETONE GLUCOSE TETROSE (C4H8O4) – ERYTHROSE, THREOSE PENTOSE (C5H10O5) – RIBULOSE, ARABINOSE HEXOSES (C6H12O6) – GLUCOSE, KETOSE – DIHYDROXYACETONE, FRUCTOSE, FRUCTOSE GALACTOSE HEPTOSES (C7H14O7) – GLUCOHEPTOSE SO ON……… 5 SOME STRUCTURE OF MONOSACCHARIDE GLYCERALDEHYDE DIHYDROXYACETONE ERYTHROSE RIBULOSE GLUCOSE FRUCTOSE GALACTOSE 6 DISACCHARIDES : 2 MONOSACCHARIDE UNITS ( SIMILAR OR DISSIMILAR ) CRYSTALLINE, WATER SOLUBLE, SWEET IN TASTE MALTOSE : MALT SUGAR , SUCROSE : CANE SUGAR LACTOSE : MILK SUGAR DISACCHARIDES 7 POLYSACCHARIDES ALMOST INSOLUBLE NOT SWEET IDEAL STORAGE AND STRUCTURAL COMPONENTS STARCH, GLYCOGEN, CELLULOSE PEPTIDOGLYCAN, HYALURONIC ACID, AGAR, CHITIN POLYSACCHARIDES 8 STRUCTURAL POLYSACCHARIDES CELLULOSE MOST ABUNDANT ORGANIC SUBSTANCE IN PLANT KINGDOM PREDOMINANT CONSTITUENT OF PLANT CELL WALL TOTALLY ABSENT IN ANIMALS CHITIN FOUND IN INSECTS ,PROVIDE STRENTH AND ELASTICITY 9 THANK YOU……… 10A Prairie Guard Dog I am on a journey. My trip is to a prairie. It is in the outdoor world called nature. Many animals live in a prairie habitat. This place has what prairie dogs need to survive. A prairie has a lot of grasses but few trees. Without places to hide, a prairie can be dangerous for some animals. Good Morning! It is early in the morning. First, I see a prairie dog. I name him Pete. He peeks his head out of his burrow underground. He looks around. Then Pete calls loudly to his family, "Yip!" He lets them know it is safe to come out. Soon four prairie dogs come out. Pete is the guard and he is restless. He cannot rest because he is always looking around for danger. This allows the other prairie dogs to safely munch on grasses and seeds. They can also groom each other or work on their burrow. A Scare Oh no! Pete spies a large badger! When he sees it, he gives a loud bark, "Yap! Yap!" His family recognizes the warning. Some hide in tall grasses, and some jump into the burrow. The badger runs at Pete, but the watchful guard is able to escape into the burrow. I am glad he is able to get away from danger. After a few minutes, Pete peeks his head out again and he is back on the job. Break Time The sun gets higher, and it is hot now. The prairie dogs slip into their deep burrow where it is cooler. Even Pete goes in. Tunnels, like hallways, lead to different areas. There is a sleeping room. There is a room used like a bathroom. The prairie dogs cover up roots and seeds in one room. Later, they eat the buried food there. Second Shift I keep watching the burrow. Finally, the sun begins to set and a different prairie dog peeks its head out. I name him Gary. Pete must be off duty. "Yip," Gary calls. The other prairie dogs come back out. The prairie dogs eat and play until the moon is high in the sky. Then they go to sleep in their burrows. I wonder if Pete will be back on duty. I will see in the morning. Conservation means prevention of loss or damage to something. Conservation of natural resources means keeping or managing and preventing our natural resources from being wasted, damaged or going into extinction, that is disappearing. Natural resources are nature’s gifts to human beings. Therefore, we should keep and manage them well. WHY NATURAL RESOURCES SHOULD BE CONSERVED(MANAGED): The following are the reasons why natural resources should be conserved(managed): 1. To prevent waste of our resources. 2. To preserve them for future use, For examples Land, trees etc. 3. To generate more income and develop our economy. For example, Zoological gardens, mineral resources and tourist centres like Ikogosi warm and cold-water spring. 4. To prevent some rare birds and animals from going into extinction (stop existing). 5. To prevent erosion. This is because these trees help to hold the soil and prevent it from being washed away easily by erosion. HOW TO MANAGE (CONSERVE) OUR NATURAL RESOURCES. The following are ways to manage our natural resources: 1. Avoiding bush burning. 2. Tree planting should be encouraged. 3. Creation of more games reserves like Yankari Game Reserve. 4. Avoiding of oil spillage and dumping of wastes into drains. 5. Adding of manures and fertilizers to enrich our soil.
