DAY & NIGHT Do you know what creates days, nights, years & seasons? Let’s see…..
Teaching Revolution at Coe • A clear distinction between revolution and rotation needs to be made. Stress this – clarify & question. • Notes here (illustrate):
What makes a year? • The complete Revolution of Earth around the sun takes a year. • Revolution is ellipsoidal, not circular, and Earth is actually closest to the sun in the northern hemisphere’s winter when it is coldest! • It takes 365.25 days for Earth to revolve around the sun. • http://www.classzone.com/books/earth_science/terc/content/visualizations/es0408/es0408page01.cfm?chapter_no=04
What creates day & night? • Rotation of Earth on its axis. • It takes 24 hours for Earth to make one rotation. • Earth rotates from east to west, so the sun rises in the east and sets in the west. • Notice Earth’s axis is at 23.5º from vertical. (This is important later.)
Teaching Day & Night at Coe • Stay in one position around the sun while you’re teaching day & night. • Rotate in the proper direction so that sunrise, morning, noon, afternoon, sunset and night at Coe Lake can be seen. • Put a 2nd & 3rd child in the Earth costume and go through this until you know they understand the concept. • Question the students for understanding.
What Creates Seasons? It's all about the direct rays & tilt! • Seasons are created because Earth is tilted 23.5º on its axis coupled with the different amounts of DIRECT sunlight the Earth receives throughout the year. • As Earth moves around the sun, the direct rays of the sun migrate from 23.5º N to 23.5º S of the equator within a year. • When the direct rays of the sun are at 23.5º N, our first day of summer begins. • When the direct rays of the sun are at 23.5º S, our first day of winter begins. • When the direct rays of the sun are at the equator (2x each year), our first day of spring and fall begin.
Teaching Seasons at Coe • Take out lesson plan for Coe Lake and review Part I. together. • Perform Part I. like you are teaching the lesson. • Class prep-time: 15 minutes • Then teach the rest of us in class! • Good luck preparing!
Constructive Criticism • Pros- Cons-
Part II. Cosmic Lab Investigation -Get out lesson plan, review Part II. together. -Complete the online activity for Part II. (link below). Become familiar with all the applications presented on site. -Each team should create an e-sheet to accompany the site and what it has to offer. -Each team will be given 45 minutes to create the e-sheet. -Each team will teach Part II. along with their e-sheet to the rest of the class and have them complete it along with the presentation. -The class will vote which e-sheet is the best for Coe Lake • http://www.sepuplhs.org/middle/iaes/students/simulations/sepup_seasons_interactive.html

New State Standard- 2015 • Regional Weather Patterns
Regional Weather Patterns – common weather patterns in certain parts of the world. EX: dry season, rainy season, monsoon season, lake effect snow A regional issue for us is: Lake Effect Snow (Video) Notes Here:
Real Time Satellite Photos of Earth- observe regional weather together! • NOAA Environmental Visualization Laboratory
Monsoons • Monsoon- changes in atmospheric circulation resulting in symmetric heating of land and sea -> rainy season AND dry season. • Region of world where this occurs: West African and Asia-Australian
Typhoons • Mature tropical cyclone in the northwest Pacific Ocean. Three different typhoons spinning over the western Pacific Ocean on August 7, 2006
