We can work together to do the transplanting efficiently. We gather in a long row across one flooded paddy, standing in the water and each carrying a handful of rice seedlings.Everyone plants one seedling in the row, and then steps back one step and planted the next row. We can quickly plant one paddy field in neat, even rows, and then move on to the next paddy field.Transplanting is hard, backbreaking work, but it is also an occasion for singing and enjoying each other’s company as we work together. NotesTransplanting is done at 21-25 days after sowing (DAS. For seed production, straight row transplanting is recommended to attain optimum plant population, facilitate, and ease weeding and roguing operations.1. Transplant the proper number of seedlings. The prescribed number of seedlings per hill is 2-3 for inbred rice and 1-2 seedlings per hill for hybrid rice to obtain the required plant population for optimum yield.2. Transplant seedlings at a depth of 2 to 3 cm; deeper planting may cause late and poor tillering.3. Using planting wire with distance markers as guide, transplant inbred for seed production at a distance of 20 cm x 20 cm for wet and dry season.4. After transplanting, apply the recommended molluscicide if golden apple snail (GAS) is a serious problem.5. Replant not later than seven days after transplanting to avoid uneven maturity. For commercial production, increase the number of seedlings per hill by 1 for each week of delay in transplanting to compensate for the reduced tillering capacity of older seedlings.6. Keep water level at 2-3 cm deep after transplanting. 2.Catch the loachloach is the main representative of a small group of fish, which can be distinguished by an elongated（變長(zhǎng)的） body, covered with fine and smooth scales, small eyes, weakly isolated gill（腮） openings, as well as filamentous tendrils. According to the data, as well as some other signs of the structure of the body of the loach, belong to the family “Cobitidae”. Loach – are freshwater fish belonging to the order carps. The average length is from 15 to 18 cm, some species grow to 30 cm. Among the habitats, the loach prefers ditches（溝） and swampy（多沼澤的） rivers, with a bottom covered with silt. This preference is due to the fact that the loach practically lives in the silt extracting feed from it in the form of river mollusks（軟體動(dòng)物）, various larvae and worms. Often the loach can be found in reservoirs（水庫(kù)） where other freshwater species are completely absent. The loach often rises to the surface before a rainstorm or thunderstorm. How to catch1.Take off your shoes and put on rainshoes. Roll up tour sleeves.2. Enter the paddy（稻田）, walk in the water and watch, the loach will be swimming or hiding in the between the silt.3.Don't get to close or the Loach will flee out to the middle of the pond. 4.If the loach is in the silt, you should hold up a handful of mud. Filter the mud and see wheather the loach is in.If the loach stay still, catch it with one hand as fast as you cab.If the loach is swimming, you'd better use a fishing net to catch.5.Put the loach you caught in the bucket filled with clean water. 晚上把捉回的泥鰍做成了兩盤菜?? GamesPart1（Sam 媽媽）：拓展農(nóng)場(chǎng)建筑物、農(nóng)場(chǎng)主工作、農(nóng)場(chǎng)車輛1. Buildings on farmsome buildings are used as shelter for animals. Others are used for storing harvested crops. Farms also may have large fields for crops.game: build a farmToday we try together to build a modern farm.M: We are farmers. This is our farm. What animals will you keep on our farm?S: Cows, pigs, lambs, ducks... M: Look, there is a pond. I want to keep some fish and ducks. Can you take fish and ducks to the pond?M: We also need a barn. Can you build a barn?A barn is an agricultural building primarily located on farms and used for many purposes, notably for the housing of livestock and storage of crops.We have a barn. We can store crops in the barn.A stable is a building in which livestock, especially horses, are kept. It most commonly means a building that is divided into separate stalls for individual animals.We can put cows in the stable.We put the pigs and sheep in their own pen by standing up some short fence. 2. Farmer's jobThey plant crops that provide food for people. They raise animals that produce food.Planting, shearing, transporting, harvesting, herding, picking, milking, collecting, feeding herd the pigsDaddies will be the pigs. Mommies will hold hands together as the pen.The pigs all get loose from the pen. Farmer has to gather up them and put them back in the pen. The dogs helps put the pigs into pens by running around them and chasing them.Shear the SheepLet's paste the double side tape and some cotton on dads' arms. Daddies are pretend sheep.Our little farmers help shear our sheep by pulling off all their wool and putting it in a sack. We use wool to make clothes.Gather the EggsOur chickens are laying eggs in the nest. Please help gather up all the eggs and put them in egg cartons.Chickens give us eggs for food.They lay eggs in the hen house. Then the farmer collects them for us.Milk the CowPlace a bucket underneath the udder.Wrap a hand around 2 of the 4 teats.Squeeze down to push out the milk.The bucket will catch the milk that you squeeze down from udder.The udder is empty, You have finished milking the cow. 3. MachinesMachines help farmers do a lot of their work.Tractors pull other heavy machines. Machines help to dig the soil. They help to plant seeds and harvest the crops.The tractor pulls a plough that digs to soil to break it up and make it ready for planting seeds. After ploughing, the seeds can then be planted by the farmer using the seed drill. The seed drill plants seeds in rows and covers them over with soil. It also adds fertiliser to the soil to feed the plants and help them grow.The seed drill is pulled by the tractor too. After the seeds have grown, the crops have to be harvested. A machine called a combine harvester helps to do this. The harvester cuts the top off the plants and separates the grains of corn, wheat, sunflowers, oats from the plants. Then the machine loads the grain into a tractor trailer. livestock transporterlivestock transport is the movement of farm animals via sea, road, rail or air. The term livestock itself is used as a combination for farm animals such as for cows, sheep, goats, pigs and horses. The purpose of transporting cattle can be for beef and other food products, dairy, breeding or simply relocation. Part2（Jaden 媽媽）：拓展食物鏈，農(nóng)場(chǎng)動(dòng)物 EnergyHello, kids! Can you jump? Can you crawl? Can you move? Yes, you are. We are living things. Can a rock jump? No, a rock is not a living thing. Is a flower living thing? Is a cow living thing? Yes, they can grow up. Plants and animals are other living things. Living things need air, sunlight, and water to stay alive. Living things also need energy. Energy is the power we need to move. We cannot do anything without energy!We need foodPlants need energy to grow and make new plants. Animals need energy to move, grow, find food, and stay safe. Where do we get our energy from? Food!Food gives plants, animals, and people the energy they need. The energy in food comes from the sun.It starts with plantsPeople and animals cannot use the energy from sunlight to make food. Only plants can make food with the sun's energy. Do you know why?Plants have a special green color in their leaves, called chlorophyll /?kl??r?f?l/. Chlorophyll catches sunlight.PhotosynthesisPlants use sunlight. air, and water to make food. A very long word describes how plants make food from sunlight.The word is photosynthesis /?fo?to??s?nθ?s?s/.Energy flowsAnimals and people cannot make food from sunlight. They have to get the sun's energy from plants. When an animal eats a plant, the sun's energy flows from the plant to the animal. When these bees eat the nectar in flowers, they are getting the energy of the sun.What is a herbivore?A herbivore is an animal that eats plants. Herbivores eat different kinds of plants. Some also eat different parts of plants. This squirrel is eating the seeds of a flower. It is getting the sun's energy from the seeds.What is a carnivore?Some animals do not eat plants. They eat other animals.Animals that eat other animals are called carnivores.What is a food chain?A food chain is the passing of the sun's energy from one living thing to another.Look at this picture. A food chain starts with plants.Next, the energy goes into the rabbit that eats the plants. When the lynx eats the rabbit, the sun's energy is passed along to the lynx.The plants, rabbit, and lynx make up the food chain. Game1：Act it outKids, come here, let’s play a game about food chain. Here are some cards, each one choose one card. OK, who are you? You are a grasshopper. You can hop, hop, hop. Please act like a grasshopper. You are a frog, you can hop, too. Please act like a frog. You are a fish. You can swim, please act like a fish. Oh, you are a bear. Please act like a bear, growl~Now I am grass. Who eat grass? Grasshopper. Grasshoppers eat plants, a grasshopper is a herbivore. The grasshopper eats the grass and grows bigger. Who eat grasshopper? Frog. A frog eats the grasshopper, and grows bigger. Use your hand to catch the grasshopper which means you eat it. The frog eats another animals, so frog is a carnivore. And then the fish eats the frogs, the fish grows bigger. Now the fish is swimming in the water. Oh, here comes the little bear. The little bear catch the fish and eat it. The bear grows bigger.Now kids come here. The grasshopper links the grass, the grasshopper links the frog, the frog links the fish, the fish links the bear. Look, this is a food chain, the food chain has five parts. The grass get energy from the sun, the grasshopper get energy from grass, the frog get energy from grasshopper, the fish get energy from frog, the bear get energy from fish. The food chain show how each living thing gets food, and how energy are passed from creature to creature. Game2：A simple food chainFood chains begin with plant-life, and end with animal-life. Some animals eat plants, some animals eat other animals.A simple food chain could start with grass, which is eaten by rabbits. Then the rabbits are eaten by foxes.Game3：Bigger Food ChainsHere's another food chain, with a few more animals. It starts with acorns, which are eaten by mice. The mice are eaten by snakes, and then finally the snakes are eaten by hawks. At each link in the chain, energy is being transferred from one animal to another.There can be even more links to any food chain. Here another animal is added. It goes Grass to grasshopper to mouse to snake to hawk.Game4：The Full Food ChainsThere is actually even more to this chain. After a hawk dies, fungi /?f??ɡi/（真菌） (like mushrooms) and other decomposers /,dik?m'poz?r/ （分解者） break down the dead hawk, and turn the remains of the hawk into nutrients/?nu?tri?nt/ (營(yíng)養(yǎng)物）, which are released into the soil. The nutrients (plus sun and water) then cause the grass to grow. It's a full circle of life and energy!!So food chains make a full circle, and energy is passed from plant to animal to animal to decomposer and back to plant! There can be many links in food chains but not TOO many. If there are too many links, then the animal at the end would not get enough energy.4.Parts of the Food ChainThe Sunis usually the beginning of most food chains. Nearly all of the energy used by living things on earth to survive originally/??r?d??n?li/ came from the sun.Producers, which are plants, produce their own food from sun, water, air (carbon dioxide), and soil.Consumers, which are usually animals, because they cannot make their own food, so they need to consume (eat) other plants and animals.There are 3 groups of consumers.Herbivore /?h??rb?v??r/Animals that eat maily plants.This includes leaves, grass, flowers, seeds, roots, fruits, bark, pollen and much more.Some herbivores are deer, horses, rabbits, cows, bees, sheep, greasshoppers.Carnivore/?kɑ?rn?v??r/Animals that eat maily animals.This includes insects and all animals.Some canivores are lions, tigers, all cats, eagles, hawks, owls, sharks, frogs, spiders.Omnivore/?ɑ?mn?v??r/：Animals that eat both animals and plants.Humans are also omnivores!Some ominvores are humans, most bears, racoon, apes and monkeys, eagulls and other birdsDecomposers, which include fungi, bacteria, and worms, eat decaying plants and animals, and decompose them back into soil. The soil can then be used by plants to grow.Fungi and bacteria play an important role in nature. They break down the unused dead material and turn them into nutrients in the soil, which plants use to grow. They are an important part of the food chain.Game5: A food webMany FOOD CHAINS make up a FOOD WEB.（1）simple chain starts with flower, which is eaten by caterpillar. Then the catepillar is eaten by bird.（2）Here's bigger food chain, with a few more animals. It starts with acorns, which are eaten by mice. The mice are eaten by snakes, and then finally the snakes are eaten by hawks. At each link in the chain, energy is being transferred from one animal to another.（3）This a bigger food chain in marine. It starts with algae, which are eaten by small fish. The small fish is eaten by big fish, and then finally the big fish is eaten by dolphin.（4）This is a mixed food chain, there are five parts in the food chain. It starts with flower, which are eaten by insect. The insect is eaten by small fish, small fish is eaten by big fish, and then finally the big fish is eaten by seagull.（5）This is a full chain. It starts with plants, which are eaten by grasshopper. The grasshopper is eaten by lizard, lizard is eaten by eagle, and then finally the eagle dies, fungi (like mushrooms) and other decomposers break down the dead eagle, and turn the remains of the hawk into nutrients, which are released into the soil. The nutrients (plus sun and water) then cause the grass to grow. It's a full circle of life and energy! So food chains make a full circle, and energy is passed from plant to animal to animal to decomposer and back to plant!（6）This is a full marine chain. It starts with plankton, which are eaten by fish. The fish is eaten by jellyfish, jellyfish is eaten by turtle. The turtle is eaten by shark, and then finally the shark dies, bacteria break down the dead shark, and turn it into nutrients, which can help plankton to grow.The energy is passed from plant to animal to animal to decomposer and back to plant!（7）This is a chain with human. It starts with plankton, which are eaten by mussel. The mussle is eaten by small fish, small fish is eaten by big fish. And then the human uses a fishing rod to catch the big fish, and then eat it.
