Hey, Dr. Binocs! Hey there. Hello, Dr. Binocs. Hello. Oh, hello! Friends, did you spot any kinda difference between these two? I'll give you 10 points if you do! No? Well, don't worry. I'll tell you how they are different from each other. But for that I need to tell you all about the Animal Kingdom! Come with me! Zoom in! The Animal Kingdom is divided into two groups. Invertebrates and Vertebrates. And today, we will talk about the invertebrates. Animals without a backbone are called Invertebrates. Which are further classified into.. Worms! Sea Jellies! Mollusks! Anthropods! And Sponges! Now, let us explore a little into their worlds! Worms! They have long, soft bodies with no legs. Oh, and two body openings. You've seen earthworms, right? If you haven't, rush to your nearest garden! Sea Jellies! Jellyfish is a good example here. They have soft and long stinging bodies. Stinging because they use their stingers to stun their prey.. ..before pulling them into their stomach. Mollusks! They have soft and warm bodies. Many of them have hard shells, like the snail. Other examples are Octopus and Squid. Anthropods! These animals form the largest group of the Invertebrates. They have their skeleton on the outside of their bodies. Creepy crawlies such as cockroaches, spiders are anthropods. Sponges! They generally live in saltwater and don't move from place to place. They filter nutrients and tiny organisms out of water, for food. TRIVIA TIME! The Invertebrates will eat almost anything that was or is alive. 97% of all animal species are invertebrates. Well, that keeps a very tiny space for the vertebrates. So do one thing, check this video out, to know more about them! So this is me zoooming out! Tune in next time, for more fun facts.Lesson 2: USES OF SOIL PRETEST Color the pictures that show how we can use soil. SOMETHING TO READ Soil is very useful to us. We can use it in many ways. Let us find out the different uses of soil one by one. Uses of soil a. Sand is used in making our houses. It is also used in making hollow blocks. OBJECTIVES: - Enumerates things that we can with soil - Demonstrates ways for making play things out of soil SCIENCE 2 – MODULE 7 SEIBO COLLEGE 9 b. Soil is made up of minerals, nutrients, water and air that support growing plants. It also keeps the plant’s roots on the ground. c. Animals like earthworm and ants lives in the soil. They create tunnels in it to allow air and water to pass through it. d. Clay soil is used in making pots and vases. We can play with it. We can make different objects that we can use to play with. e. When we are at the shore of the beach, we can play with sand and build sand castles. SOMETHING TO DO ACTIVITY 1 Creating Things I Like Objective: In this activity, children will learn that they can create things out of clay. What you need: SCIENCE 2 – MODULE 7 SEIBO COLLEGE 10 2 bars of clay (any color) 1 pc. 1/8 illustration board or any hard board What to do: 1. Using the bars of clay, create things that you like then place them on the illustration board. 2. Show your work to your facilitator. Observation: 1. Is it easy for you to create things that you like out of clay? __________________________________________________ 2. What is the texture of the clay? ________________________ 3. Did you have fun dong this activity? _____________________ Conclusion: I therefore conclude that _Wiggly Worms Small Animals, Big Changes. Do you know about earthworms? These small animals change the soil in big ways. Earthworm Bodies. An earthworm's body is shaped like one tube inside another. On the outside is a tube of muscle. On the inside is a tube that breaks down food. The body of an earthworm is made up of many parts. Each part is shaped like a ring and can bend and stretch. Earthworms move by stretching out their bodies and pulling themselves forward. Short, tough hairs on their bellies help them hold onto the ground. Slimy Worms! Earthworms are slimy. The slime helps keep earthworms cool and wet. It also helps earthworms slide through soil. After worms mate, a ball of slime forms. The slime dries into a cocoon. Baby worms come out of the cocoon. Earthworm Behavior. Earthworms build long tunnels underground. The tunnels protect worms from heat and sunlight. They also help earthworms hide from hungry animals. Earthworms are sometimes called night crawlers because they come out at night to feed. They use their mouths to pull dead leaves and plants into their tunnels. Earthworms Are Good for the Soil. Farmers love earthworms! When earthworms dig tunnels, they make space in the soil. The space helps plants get what they need to grow. Some people raise earthworms on worm farms. The earthworms eat food scraps, turning them into rich soil. Earthworm waste helps plants grow big and strong. Wanted: Earthworms! Farmers aren't the only ones who love earthworms. Moles, rats, and toads love juicy night crawlers. They love to eat them! Worms make good fishing bait because fish think earthworms are tasty, too. Earthworms are important food for these and other animals. Earthworms may be small, but they have a big job. Earthworms help plants grow!In a single domesticated grain seed, one might see the bud of great civilizations. The birth of agriculture was a turning point in humans' social development, as stable food supplies enabled people to transcend the constraints of food gained by hunting and gathering. After that, people were able to settle down and experience population booms. As one of the major areas around the globe where agriculture originated, China has contributed to the world's domesticated rice, millet, buckwheat and soybeans. Archaeological studies have unveiled that the planting of rice originated around 10,000 years ago in the lower reaches of the Yangtze River, leading to the eventual replacement there of hunting and gathering practices dating back 5,000 to 6,000 years. "It marked the formation of a rice-based agricultural society in the area," said Zhao Zhijun, an archaeologist at the Chinese Academy of Social Sciences. Archaeological studies of the origins of rice-based agriculture are an important part of a national project tracing the origins of Chinese civilization itself. President Xi Jinping has greatly valued the project. At a group study session of the Political Bureau of the Communist Party of China Central Committee on May 27, 2022, Xi, who is also general secretary of the CPC Central Committee, emphasized the significance of the project and the role that archaeological studies play in better understanding Chinese civilization. The project to trace the origins of Chinese civilization, in addition to finding signs of human activity more than 1 million years ago, has also proved that China's history includes 10,000 years of culture and more than 5,000 years of civilization. The project has provided clear knowledge of the origins and formation of Chinese civilization, the history of its development, the process of the formation and development of its pluralistic and integrated pattern, and the characteristics of the civilization and why it was formed in such a way, he added. This was not the first time that Xi emphasized the importance of the origin-tracing project. Since the 18th National Congress of the CPC in 2012, Xi has toured more than 100 historical and cultural locations and issued many instructions related to archaeology and the origin-tracing project. During the 23rd group study session of the Political Bureau of the CPC Central Committee in 2020, Xi called for giving more attention to archaeological research and letting historical facts speak for themselves. "This will provide strong support for our efforts to carry forward the best of traditional Chinese culture and increase our cultural confidence," said Xi. The origin-tracing project has been carried out since 2002. Its ongoing fifth phase, which started in 2020, involves the participation of more than 500 researchers from 29 institutes across the country. It primarily centers on several ancient capital sites, including the Liangzhu site in Hangzhou, Zhejiang province, the Taosi site in Xiangfen county, Shanxi province, the Shimao site in Shenmu, Shaanxi province, and the Erlitou site in Luoyang, Henan province, from 3,500 to 5,500 years ago, as well as other settlements mainly along the basins of the Yellow, Yangtze and Liaohe rivers. The project has also expanded to a wider geographic and chronological framework to decode how Chinese civilization emerged and how its diverse elements formed a unity. Excavation of the Liangzhu site, which is over 5,000 years old and is one of the major sites covered in the origin-tracing project, has yielded an inner city covering 3 million square meters and an outer city of 6.3 million sq m, making it the world's largest capital at the time. It also had a giant water control system, which contributed to the formation of a rice-based agricultural society. By calculating the earthwork volume, archaeologists found that building the entire ancient city, the water control system and Mojiaoshan — a 10-meter-tall man-made terrace in the center of the city — required 10,000 people working daily for seven-and-a-half years. The discoveries show that Liangzhu had a kingship able to organize people for large-scale public construction, and its social differentiation, emergence of the city concept and existence of a kingship prove that it became a civilized society, said Wang Wei, a veteran archaeologist at the Chinese Academy of Social Sciences. Significant topic Wang said that tracing the origins of a civilization is a significant topic in the research of human history. Over the years, the Chinese project has provided China's answer to how to define civilizations. In 2022, Xi commended the efforts and stressed that the project has made creative contributions to the research on tracing the origins of the world's civilizations. Wang said: "International academia has proposed three indispensable elements for a civilized society based on features of Mesopotamian and Egyptian civilizations: written characters, metallurgy and the city concept. But we can find that some of the three elements were absent in many ancient civilizations. For example, the Mayan civilization had no metallurgy, while the Incan civilization didn't have written characters." Western scholars believe that Chinese civilization began with the Yinxu Ruins in Anyang, Henan province, a capital of the late Shang Dynasty (c.16th century-11th century BC), based on the discovery of inscribed oracle bones from that time. However, Chinese archaeologists don't agree. With continued archaeological research, international academia now believes that places around the world can propose criteria for civilization based on their own ancient social development. China's archaeological studies have shaped the nation's criteria in defining a civilization: the development of productivity, an increase in population, the appearance of cities, social differentiation and the emergence of kingship and state. "These criteria are suitable for identifying other civilizations as well," said Wang. "Civilizations have in common the appearance of kingship and state. They are only different in the ways of imposing kingship and the forms of state." In China, kingship and state "were shown by exquisite jade and bronze ritual artifacts, grand palaces and magnificent mausoleums imitating aboveground palaces", he added. "In Mesopotamia and ancient Egypt, they were demonstrated through superb stone temples, pyramids and large-scale tombs." Multidisciplinary subject President Xi said in 2020 that archaeologists should work closely with researchers from other fields to make an interpretive analysis of material remains. Zhang Chi, a professor of archaeology at Peking University, said that since material remains are often the research focus of archaeological studies, these should not only be observed with the eyes, but also studied using scientific and technological tools. Therefore, from the perspective of research methods, archaeology is by nature a multidisciplinary subject, Zhang added.1Choose the correct answer: 1.The...........of plant absorb water and nutrients from the soil.

Mineral matter • Provides nutrients such as zinc, nitrogen and potassium. •It comes from rocks that would have broken down to form soil. •It is the main component in soil. 2. Soil Organic matter • Provides nutrients to the plants/ increases soil fertility •Improves soil structure •Improves soil temperature •Improves water holding capacity •Improves aeration •Soil air is needed by roots for their respiration •It is needed by soil organisms like earthworms, fungi and bacteria •Is needed for germination of seeds Soil water •Provides plants with water for growth •Dissolves plant nutrients •Is needed for germination of seeds •Keeps the soil moist so that micro-organisms can workNot very musical What can music do? Music Helps Plants Grow Faster A study used 14 different classical pieces, including Beethoven's Moonlight Sonata, in rice fields. People found that the music helped the crops grow at a faster pace, and plants have genes which make them 'hear'. When listening to slow music, cows produce more milk. While cows that listened to rap showed no increase in milk production, those who listened to slow, soothing songs produced 3 percent more milk. That's because when a cow is stressed, it slows down the release of oxytocin(å‚¬äº§ç´ ), which is important for producing milk. So playing music relaxes them to help them produce more milk. A song that gets stuck in your head is called an earworm. An earworm refers to catchy music that continually repeats through a person's mind, even after it's not playing. A person's experiences may bring up a memory of a song, such as seeing a word will remind you of the song.Earthworm response to water(Observation and conclusion)
