Open up your laptops, go to MrHyatt.rocks, and do today’s bellwork Scale Scale Description 4 Through independent work beyond what was taught in class, you could: investigate the location of seasonal constellations in the local sky. predict location of constellations at future times. determine the celestial equator, latitude and position of the Pole Star for a given position on the Earth. determine the distances of stars in a given constellation to each other and to Earth. 3 You will be able to: describe and apply the coordinate system used to locate objects in the sky. distinguish the various methods of measuring astronomical distances and apply each in appropriate situations. 2 determine the meaning of symbols, key terms, and other astronomy specific words and phrases as they are used in context to relevant topics label diagrams with degree measurements describe how or why different units of measurement are needed for distances in space 1 You will be able to list the different units of measurement needed to measure distances in space

Which diagram best represents the SIZE of the Sun, Earth and Moon?

Reminder….

your assignment… Create a model Create a model that shows the relationship between the size and distance of the earth and moon (sun won’t fit, so add the information, but don’t draw it) Create a model

With the people at your table…fill in this chart using information from the back of this textbook Then draw the earth and the moon to scale in your science journals (using a pushpin from my desk) A pushpin has a diameter of roughly 10mm (Please don’t steal my pushpins) Be mindful of your units! Diameter of Earth Diameter of Moon Earth-Moon Distance Earth to Sun Diameter of Sun Actual (appendix in back of book) km (page 185 ) km (page 184) km (yesterday’s notes) km (appendix) km Scale 10mm Did I mention there was going to be math this year???

To Receive points for today: Answer these five questions in Canvas Was your result what you expected? Why or why not? How many meters away would the sun be? What object would you have to use to trace the sun? How many pages would you need in order to draw the Sun and Earth to scale? Why are models useful in science? Why are they useful for astronomy in particular?
