What is fusion and how is it a factor for the life on earth?
Open up your laptops, go to MrHyatt.rocks, and do today’s bell work Questions of the week: What is the sun responsible for in our solar system? What is fusion and how is it a factor for the life on earth? Scale Scale Description 4 Through independent work beyond what was taught in class, I can (examples include, but are not limited to): research current and past earth and sun conditions. investigate causes and possible solutions for global climate change. compare and contrast the patterns in the organization and distribution of matter in the sun, earth, moon system. compare and contrast different solar events and their impact on earth. 3 I can: identify patterns in the organization and distribution of matter in the universe and the forces that determine them. explain the physical properties of the Sun and its dynamic nature and connect them to conditions and events on Earth. identify, analyze, and relate the internal (Earth system) and external (astronomical) conditions that contribute to global climate change. describe heat as the energy transferred by convection, conduction, and radiation, and explain the connection of heat to change in temperature or states of matter. 2 determine the meaning of symbols, key terms, and other astronomy specific words and phrases as they are used in a specific technical context relevant to grades 9-12 texts and topics identify from a list the patterns of distribution of matter in the sun, earth, moon system. list the physical properties of the sun describe the key parts of the structure of earth and earth’s atmosphere. explain ways in which to measure temperature. 1 show the patterns of distribution of matter in the sun, earth, moon system. select from a list the physical properties of the sun, earth and moon. list the key parts of the structure of earth, sun and moon.

Homework: that was due today…
You need to look up the following information about each layer of the sun: Size What it’s made of Temperature One other fact These are the layers: Core Radiation Zone Convection Zone Photosphere Chromosphere Corona

Review from yesterday The gravitational force of the sun helps to keep all of the planets in the solar system in the correct orbit. The energy from the sun sustains life on earth. The sun contains 98% of all the mass in our solar system The sun is not solid, liquid or gas, it is plasma. Plasma is similar to gas, except the gas is ionized (charged).

Sun features – write these down, then talk with your neighbor and try to figure out what each one of them is Prominence/filament Flare Granule Sunspot Spicule Coronal Mass Ejections

Solar Prominence Sunspot Spicule Granule Flare Solar Magnetic Field
Coronal Mass Ejection (CME) Flare Solar Magnetic Field A Magnetic Field is the magnetic effect of electric currents and magnetic materials. In a star, it is generated by the motion of electrically conductive plasma inside its convection zone, where solar material is physically moving throughout the star. A coronal mass ejection is a massive burst of gas and magnetic field arising from the solarcorona and being released into the solar wind, as observed in a coronagraph. Gurgling plasma on the Sun produce periodic, supercharged jets of dense gas ejected from the edges of the Sun’s chromosphere where the magnetic fields are stronger. They rise at 12 miles/second up to a height of about 6,000 miles before they fall back to the Sun after about 15 minutes. They are thought to contribute to the solar wind by feeding material into the corona Sunspots are any of the dark cool patches, with a diameter of up to several thousand kilometers, that appear on the surface of the sun and last about a week. They occur in approximately 11-year cycles and possess a strong magnetic field Granules on the photosphere of the Sun are caused by convection currents (thermal columns, Bénard cells) of plasma within the Sun's convective zone. The grainy appearance of thesolar photosphere is produced by the tops of these convective cells and is called granulation A prominence is a large, bright, gaseous feature extending outward from the Sun's surface, often in a loop shape. Prominencesare anchored to the Sun's surface in the photosphere, and extend outwards into theSun's corona. A flare is a brief eruption of intense high-energy radiation from the sun's surface, associated with sunspots and causing electromagnetic disturbances on the earth, as with radio frequency communications and power line transmissions.

FUSION What is it? Combining atoms to make new ones
4.3 billion kg of mass are converted each second. Lots of mass lost, lots of energy released. (E=mc2) Iron (Fe) is the heaviest element that can be made How do we get heavier elements?
