The Milky Way and the Andromeda Galaxy are part of the Local Group of 50 closely bound galaxies within the larger Virgo Supercluster.
Dwarf Planets and Pluto / Kuiper Belt and Oort Cloud
Pluto is a dwarf planet located in the Kuiper Belt, a region beyond Neptune populated with small icy objects. While Pluto meets two of the three criteria to be considered a planet by orbiting the sun and having sufficient mass to be rounded, it has not cleared its orbit of other objects. Its highly elliptical orbit crosses Neptune's orbit and takes 248 Earth years to revolve around the sun. The Kuiper Belt contains remnants of unformed planets and extends past Neptune out to the distant Oort Cloud, which contains trillions of icy comets nearly a million times farther from Earth.
4 planet Mars
Mars is the fourth planet from the Sun and named after the Roman god of war. It has a thin atmosphere composed primarily of carbon dioxide. The surface is dry and cold, with temperatures ranging from about 80°F down to -207°F. Mars has two small moons called Phobos and Deimos that are irregularly shaped and may be captured asteroids. NASA has sent several orbiters and rovers to explore Mars, including Pathfinder, Spirit, Opportunity, and Curiosity. The rovers discovered evidence that Mars once had water on its surface.
Our solar system
There are 8 planets in our solar system. We live in the Milky Way galaxy. The planets in order from the sun are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Earth is the third planet from the sun and the only one with life. It is mostly made up of water and has oxygen needed for living organisms. The Earth rotates daily and revolves yearly around the sun, causing seasons and months.

1. Skeletal muscles contract when stimulated by nerve impulses, pulling on bones via tendons near joints to cause movement.
2. Joints are where bones meet, connected by ligaments which allow movement. Cartilage and synovial fluid act as shock absorbers and lubricants at joints to reduce friction between bones.
3. Antagonistic muscles like the biceps and triceps work in opposition to flex and extend joints, with actin and myosin fibers interacting in sarcomeres to power muscle contraction through ATP energy.
how bones move
Muscles and bones work together to enable movement in the human body. There are four main types of joints - ball and socket, pivot, hinge, and gliding - that connect bones and allow movement. Muscles contract and relax to cause bones to move at the joints, with cartilage providing cushioning and support.

8-2. Movement in humans
The document summarizes the key components of the human musculoskeletal system. It describes that the system consists of bones and muscles, with bones forming the skeleton and muscles enabling movement. The skeleton is made up of 206 bones that are classified into groups like the skull, vertebrae, ribs, and bones of the upper and lower limbs. The bones provide shape, protection, and sites for muscle attachment in the body. Muscles are able to contract and move the bones to enable bodily movement and functions.
YOUR BODY - BONES, MUSCLES AND JOINTS
The document discusses the human body's skeletal system and muscles. It describes some of the major bones in the skeleton including the skull, spine, ribs, pelvis, femur, tibia, fibula, humerus, and bones in the hands and feet. It notes that bones are hard and give the body shape and protection. The document also mentions some muscles like the biceps, triceps, and muscles in the face, abdomen, back, legs, and explains that muscles are soft, can contract and stretch, move the bones, and allow the body to move. Muscles also allow facial expressions.
Lesson 14 Bones and Muscles
The document discusses the skeletal and muscular systems of the human body. It describes the two main groups of bones - the axial skeleton (skull, vertebral column, ribs) and appendicular skeleton (shoulder, pelvis, arms, legs). It explains how bones are connected by joints, including movable joints like ball-and-socket and hinge joints. The document also outlines the functions of muscles in moving bones and protecting organs, describing voluntary, involuntary, and cardiac muscles. In under 3 sentences, the document provides an overview of the skeletal and muscular systems and their basic structures and functions.
Bones and muscles

It provides details on the number of bones kids and adults have, names the longest, heaviest, and strongest bone as well as the smallest bone. The document also specifies the number of teeth kids and adults have and describes how muscles can contract and relax.
ECGS Module 11
The skeletal, muscular, and integumentary systems work together to support the human body.
The skeletal system consists of 206 bones that provide structure, protect organs, allow for movement, produce blood cells, and store minerals. Bones are composed of compact and spongy bone tissues. The muscular system contains over 600 muscles that enable movement and other bodily functions through contraction. Muscles are categorized as voluntary or involuntary. The integumentary system includes the skin, hair, and nails, and forms a protective barrier against damage, disease, dehydration, and temperature changes.
Muscles & Bones Topic 11.2
The document discusses muscle structure and function, including:
1) Muscles contract through the sliding of actin and myosin filaments, powered by ATP hydrolysis in the myosin cross-bridges.
2) Calcium released from the sarcoplasmic reticulum binds to troponin, allowing myosin to bind to actin and the power stroke to occur.
3) Repeated binding and detachment of myosin cross-bridges causes the filaments to slide past each other, shortening the sarcomere and muscle.

Units 7 and 8, energy
This document discusses different forms of energy including light, sound, heat, and electricity. It describes renewable energy sources like solar, wind, and hydropower, as well as non-renewable sources like coal, oil, and natural gas. The document explains that light is a form of electromagnetic radiation that can be separated into a spectrum using a prism. It also discusses how electricity is produced from the movement of electrons in conductors like metals, and how insulators like rubber do not allow the flow of electricity.
Forces
Forces are pushes or pulls that allow objects to move or be moved. Forces can come from magnets, people pushing or pulling objects, wheels that lift things, screws that move themselves or other objects, or combinations of simple machines like wheels, axles, levers and screws working together. Forces are involved whenever an object's motion changes or an object is lifted.
Unit 7 Materials
Matter is anything that occupies space and has mass, with properties including size, shape, color, length, and volume. Matter can be definite or indefinite in volume and shape, and comes from both living and non-living things, including being found underground, coming from trees, animal skins, and plants, and being transformed into materials like oil into plastic, wood into paper, and sand into glass. Mixtures occur when two or more kinds of matter are combined but can be separated, unlike changes where a material is transformed into something different in a non-reversible process.
Human habitats
This document discusses where humans live and the key aspects that support life, including obtaining food and water, building shelters, transporting resources, and interacting with the natural environment both positively through activities like farming and negatively through pollution. Humans grow food, process and transport it from farms to cities, use irrigation to water plants, build houses for shelter, and must work to reduce pollution and protect the environment through activities such as reforestation.
Water
The document discusses the water cycle and the different states of water. It describes how water moves between oceans, atmosphere, land and underground as liquid, gas and solid through various processes like evaporation, condensation, precipitation and subsurface flow. Water continuously circulates between these different reservoirs through this hydrologic cycle driven by energy from the sun.
What is a natural landscape
This document defines and describes different types of landforms and bodies of water on Earth's surface. It explains that landforms are natural shapes found on land, and includes mountains, hills, valleys, plains, plateaus, rivers, lakes, cliffs, and glaciers as examples. It also defines oceans as the largest bodies of water, covering 70% of the planet, and influencing weather and temperature. Seas are described as smaller than oceans and partly enclosed by land.
Unit 5
The atmosphere is a blanket of air composed of nitrogen, oxygen, and other gases that covers and protects the Earth. It has 5 layers including the troposphere where weather occurs and planes fly, the stratosphere, mesosphere, thermosphere where astronauts orbit, and the outermost exosphere. Various instruments are used to measure elements of the atmosphere like temperature, wind, rainfall, and humidity.
