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.

sunspots

Today’s question What information about the sun can we gather from sunspots?

Galileo’s Observations

Sunspot in UV light

What is a Sunspot? temporary dark spots on the photosphere caused by intense magnetic activity. This slows down convection and forms areas of reduced surface temperature. have two poles (like magnets) temperatures of roughly 3000–4500 K (2727–4227 °C), the contrast with the surrounding material at about 5,780 K leaves them clearly visible as dark spots

What is a Sunspot? Sunspots expand and contract as they move across the surface of the Sun and can be as large as 80,000 kilometers (50,000 mi) in diameter, making the larger ones visible from Earth without the aid of a telescope.  They may also travel at relative speeds up to a few hundred m/s when they first emerge onto the solar photosphere.

What do Sunspots do? solar flares Prominences (coronal loops) sunspots are usually the origin point for several other sun events, such as:   solar flares  Prominences (coronal loops) coronal mass ejections

Graphing Sunspots Complete graph to determine sunspot cycles. Set up graph with time on x and sunspots on y Graph a point at every year Each group member should graph a different set of data. Each member of a group of 4 should do ~80 years. Look at your maximum number and minimum number to determine the scale 1: 1700-1780 2: 1781-1860 3: 1861-1940 4: 1941-2015 2010: 16.5 2011: 56 2012: 57 2013: 65 2014: 79.3 2015: 69.7
