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):

Earth's Revolution Skit with Costumes and short movie.

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.

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.

The Four Seasons

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!

Pros- Cons-

Part II. Cosmic Lab Investigation

http://www.sepuplhs.org/middle/iaes/students/simulations/sepup_seasons_interactive.html

-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

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
