Why do we have day and night?. Earth’s rotation  The Earth rotates on its axis (imaginary vertical line around which Earth spins) every 23 hours & 56.

What causes seasons? The tilt of the Earth on its axis The 23.5° tilt is caused by the interaction between the Moon and the Earth.

Seasons on Earth Two reasons the Earth has seasons: 23.5 degree tilt

Seasons. Seasons happen because of Earth’s tilt on its axis AND revolution around the Sun. Axis- imaginary line drawn from the north to the south pole.

Axis: imaginary line that passes through Earth’s center and the North & South Poles Earth’s axis tilt = 23.5° causes Earth’s seasons causes ‘length’ of.

Schedule for the Week Today- The Seasons Tuesday- Moon Phases Wednesday- Eclipses Thursday- Mrs. Pietrocini Friday-Projects & Presentations

Question of the Day At which diagram will Ohio experience the season of Summer?

The Earth Moon Sun Relationship Part 1

How are the sun, moon, and Earth related? By their movements. 1. Rotation- the spinning of Earth on its axis 2. Revolution- the movement of the Earth & moon around the sun. the movement of the moon around Earth Explore a model of Earth's daily rotation. Explore a model of Earth's yearly revolution around the sun.

Spring Summer Fall Winter

The Seasons of Earth Q. Why does Earth have different seasons? A. Earth has different seasons because its axis is tilted as it revolves around the sun. Earth’s axis is always tilted at 23.5 degrees. Seasons_Interactive.swf Earth-Sun Relations

Solstice Twice each year the sun reaches its greatest distance north or south of the equator. Summer solstice- the day when the sun is farthest north of the equator. June 21 Winter solstice- the day when the sun is farthest south of the equator. December 21

Equinox Halfway between the solstices. Twice a year. Means “equal night” 12 hours of day 12 hours of night Vernal equinox- start of spring. March 21 Autumnal equinox- start of fall. Sept. 21

The Midnight Sun or Noon Moon What do you think happens at the poles during the solstices? Areas around the poles experience 24 hours of daylight during the summer months. http://science.sbcc. Seasons_Interactive.swf

Skills Lab Earth experiences changing seasons because of the tilt of Earth’s axis and its revolution. Objective: Create a model using clay that represents the relationship between the Earth, sun, and the changing seasons. Procedure: 1. Chose 1 color and create a model of the sun. Remember: The sun is much larger than Earth. 2. a. Use the 2nd color and create 4 models of Earth b. Take the skewers and insert them through the Earth’s so that Earth’s axis is tilted roughly at 23° 3. Create a model in which the Earths circle the sun and are in the proper position according to the seasons.
