Why does it seems that the sun move
The document discusses the motion of the Earth and how it causes day and night as well as apparent motion of the sun. It explains that the Earth rotates on its axis every 24 hours, which causes one side of the Earth to face the sun while the other side faces away, creating day and night. It also discusses how the Earth revolves around the sun over the course of 365 days.

All living things go through life cycles that involve different stages of development. The butterfly's life cycle has four main stages: egg, caterpillar, pupa, and adult butterfly. As a caterpillar, it eats leaves and grows quickly before forming a pupa and undergoing transformation inside until emerging as a young butterfly and finally a mature adult butterfly that can lay new eggs.
How can a simple machine reduce force
Simple machines make work easier by changing the amount or direction of force needed. There are six basic types of simple machines: the lever, pulley, wheel and axle, inclined plane, screw, and wedge. Compound machines combine two or more simple machines; examples include scissors, bicycles, and wheelbarrows.
Push and pull
This document discusses how forces like pushes and pulls cause motion by either moving things away (push) or bringing them closer (pull). It defines any push or pull that moves an object as a force. The document encourages the reader to have a wonderful day.
How does soil affect living things
The document discusses the formation and composition of soil. It explains that soil is formed over long periods of time through the weathering and breakdown of rocks and the decomposition of dead plants and animals. The soil is made up of weathered rocks, humus from decomposed materials, and minerals. It has distinct layers with varying properties including the topsoil, subsoil, and bedrock below. Different types of soil like sand, silt, and clay are determined by the size of particles. Loam is an ideal soil made of a mixture of these. The document emphasizes the importance of protecting soil as a vital natural resource.
How do we use air & water
This document discusses different types of water resources and how water is treated and distributed for human use. It explains that there are two main types of water - fresh water found in rivers, lakes, glaciers etc. and salt water found in oceans. It then outlines several key steps in treating water from rivers and lakes, such as allowing solids to settle, filtering through layers of sand and gravel, adding chemicals to kill harmful organisms, and pumping the clean water for distribution.

Natural disasters and diseases can change environments and affect living organisms. Floods occur when heavy rain falls in a short period, covering land with water, while droughts are long periods without rain that can dry up rivers and lakes, increasing wildfire risks that damage plant and animal habitats. Diseases from mold, bacteria, and mildew also easily spread in environments and harm living things, with one infected tree having the potential to destroy an entire forest.
Plants needs
Plants need five things to survive and grow: oxygen from the air, water, nutrients found in soil, space to grow freely, and sunlight. Fruits were once living parts of plants but become non-living when picked after ripening.
Adaptation
Organisms adapt traits that help them survive in their environments. Some examples of adaptations include camouflage, mimicry, nocturnal behavior, hibernation, and migration. Camouflage allows animals to blend into their surroundings and hide from predators or to ambush prey. Mimicry enables some animals to resemble other organisms for protection. Nocturnal habits, hibernation, and migration are ways animals adapt to changes or shortages in their environments like weather changes or lack of food sources. Plants also exhibit adaptations like deep roots that help them survive in difficult conditions.
Volume
Liquids and gases take the shape of their container, unlike solids which do not. Volume is defined as the space occupied by matter, and can be measured using tools like measuring cups. Common units for measuring volume include liters and milliliters.
How do ecosystems compare
The document compares different ecosystems by describing their climates and key characteristics. Tropical rainforests have hot, wet climates all year and contain the greatest diversity of plants and animals. Temperate forests' climates change with warm summers and cold winters, and they receive less rain than rainforests. Wetlands are covered in water most of the year, found along rivers and coasts, and help absorb flood waters and cleanse dirty water. Oceans are the largest ecosystem and most living things inhabit the sunlit, shallow areas near the surface.
Food chains and food webs
Food chains and food webs show how energy passes from one organism to another as they eat each other. A food chain tracks the flow of energy starting with a plant that gets its energy from the sun, then to an animal that eats the plant, then another animal that eats the first animal. A food web is more complex, showing that organisms can be part of multiple food chains as some animals eat different plants and other animals.
Herbivores, carnivores and omnivores
This document discusses three categories of animals based on their diets: herbivores, which eat only plants; carnivores, which eat only meat; and omnivores, which eat both plants and meat. Herbivores include deer, rabbits, elephants, turtles, monkeys and giraffes. Carnivores include lions, crocodiles, snakes and eagles. Omnivores include bears, raccoons, pigs, and humans.
Ecosystem
An ecosystem is a place where living and non-living things interact, and can exist in various environments from wet to dry and small to large. In an ecosystem, living things depend on each other and non-living things like water, soil and sunlight. Producers like plants make their own food through photosynthesis, while consumers like animals obtain food by eating other organisms, and decomposers like worms break down dead plants and animals and return nutrients to the soil.
Habitat 180115095217
This document discusses habitats and the different animals that live in each one. It explains that a habitat provides all the needs for animals to survive, including food, water and shelter. It then identifies the five main habitats as ocean, forest, desert, grasslands, and Antarctica, and provides some example animals for each one. The habitats differ in their characteristics such as being wet or dry, hot or cold, containing trees, grass or snow.
Frog life cycle
The frog life cycle consists of 5 stages - eggs are laid in water, tadpoles hatch with gills and swim, tadpoles grow legs and lungs and become young frogs, young frogs resemble adult frogs and live on land, frogs undergo complete metamorphosis as each stage looks physically different.

All living things go through life cycles with different stages of growth and development. A life cycle can involve complete or incomplete metamorphosis. The butterfly undergoes complete metamorphosis through four stages - egg, larva (caterpillar), pupa, and adult butterfly - with the caterpillar eating leaves and the pupa undergoing transformation inactive inside its casing before emerging as a butterfly.
Presentation1 180422081713
The document describes the life cycles of humans, animals, plants, and butterflies. It explains that humans progress through stages from baby to boy/girl to man/woman to older. The butterfly life cycle has 4 stages - egg, larva/caterpillar, pupa, and adult butterfly. The caterpillar hatches from the egg and eats voraciously to grow, then forms a pupa where it undergoes transformation before emerging as an adult butterfly.
Graduated cylinder
Sally's new shoes did not fit because they were too big. To find the correct size, she needs to measure her feet with a ruler to know her exact shoe size. A ruler can also be used by Sam and Adam to determine who has the longer pencil case. However, a ruler cannot measure the volume of water in a cup, for that a graduated cylinder is needed. Charlie can use a balance at the grocery store to accurately measure 1 kilo of apples and 2 kilos of bananas. A digital balance is also used in labs to precisely determine the weight of objects.
Lab tools riddle
Safety goggles are needed to protect eyes in the lab. A thermometer will be used by Sam's mother to check if he has a fever. Sally will use a timer to measure how long it takes ice to melt during her experiment.
Magnets
Magnets can attract objects made of iron, steel, or nickel without touching them by pulling the objects through solid, liquid, or gas. Magnets have two poles, a North and a South, that either attract or repel each other or other magnets depending on whether the poles are the same or different. Strong magnets can attract objects from farther away than weaker magnets.
Recycle
The document discusses how to save natural resources using the three Rs: reduce, reuse, and recycle. It provides examples of reusing food jars and plastic wrap instead of throwing them out, reducing the use of plastic bags by bringing cloth bags to the market, and recycling old newspapers by making them into plant pots. Practicing the three Rs helps conserve natural resources for future use since they cannot be replaced once depleted.
Flowering plant life cycle
Plants reproduce through a life cycle where a seed germinates when it receives water, air, and the proper temperature, sprouting a seedling. The seedling grows into an adult plant with roots, stems, leaves, and flowers. The flowers then produce fruits containing new seeds, which when released can start the cycle again by germinating into new plants.
Pollution
Pollution occurs when harmful substances affect land, water, or air. Land pollution involves trash improperly disposed of on the ground. Water pollution is caused by dumping rubbish and other harmful materials directly into bodies of water. Air pollution results from emissions from vehicles, large factories, and bonfires that introduce smoke and gases into the atmosphere, negatively impacting human health and the environment. It is important to reduce pollution and keep the Earth clean for current and future inhabitants.

Candidate young stellar objects in the S-cluster: Kinematic analysis of a sub...
Context. The observation of several L-band emission sources in the S cluster has led to a rich discussion of their nature. However, a definitive answer to the classification of the dusty objects requires an explanation for the detection of compact Doppler-shifted Brγ emission. The ionized hydrogen in combination with the observation of mid-infrared L-band continuum emission suggests that most of these sources are embedded in a dusty envelope. These embedded sources are part of the S-cluster, and their relationship to the S-stars is still under debate. To date, the question of the origin of these two populations has been vague, although all explanations favor migration processes for the individual cluster members. Aims. This work revisits the S-cluster and its dusty members orbiting the supermassive black hole SgrA* on bound Keplerian orbits from a kinematic perspective. The aim is to explore the Keplerian parameters for patterns that might imply a nonrandom distribution of the sample. Additionally, various analytical aspects are considered to address the nature of the dusty sources. Methods. Based on the photometric analysis, we estimated the individual H−K and K−L colors for the source sample and compared the results to known cluster members. The classification revealed a noticeable contrast between the S-stars and the dusty sources. To fit the flux-density distribution, we utilized the radiative transfer code HYPERION and implemented a young stellar object Class I model. We obtained the position angle from the Keplerian fit results; additionally, we analyzed the distribution of the inclinations and the longitudes of the ascending node. Results. The colors of the dusty sources suggest a stellar nature consistent with the spectral energy distribution in the near and midinfrared domains. Furthermore, the evaporation timescales of dusty and gaseous clumps in the vicinity of SgrA* are much shorter ( 2yr) than the epochs covered by the observations (≈15yr). In addition to the strong evidence for the stellar classification of the D-sources, we also find a clear disk-like pattern following the arrangements of S-stars proposed in the literature. Furthermore, we find a global intrinsic inclination for all dusty sources of 60 ± 20◦, implying a common formation process. Conclusions. The pattern of the dusty sources manifested in the distribution of the position angles, inclinations, and longitudes of the ascending node strongly suggests two different scenarios: the main-sequence stars and the dusty stellar S-cluster sources share a common formation history or migrated with a similar formation channel in the vicinity of SgrA*. Alternatively, the gravitational influence of SgrA* in combination with a massive perturber, such as a putative intermediate mass black hole in the IRS 13 cluster, forces the dusty objects and S-stars to follow a particular orbital arrangement. Key words. stars: black holes– stars: formation– Galaxy: center– galaxies: star formation

Photometric and spectroscopic followup with NIRCam and NIRSpec, respectively, confirm the redshift and yield UV-NIR light-curve, NIR color, and spectroscopic information all consistent with a Type Ia classification. Despite its classification as a likely SN Ia, SN 2023adsy is both fairly red (
