RecapRevolve/Rotate Visual VocabRelate the following words
to Revolve or Rotate:
*Spin*Orbit
*365 Days
*Day/Night*Seasons
*Year*24 hours
Direct vs Indirect Light
Investigating Earth’s Seasons:Pre-Investigation
1. Identify the equator and the Earth’s axis on your model. 2. Identify the sun in your model3. Make sure the Earth’s axis is tilted at a 23 degree angle in the cup4. Make sure your Earth’s North Pole is pointed towards Polaris, the North Star
Seasons on a Plate
Procedure:
1. Place the foam ball at Position A.
2. Shine the flashlight towards the Earth.
3. In your journal, record your observations about the area of Earth that receives the most direct energy.
4. Move the area counterclockwise through Positions B, C, & D.

Teacher Demos and Explanation
Seasons
Day and Night
*The angle at which the sun’s rays strike the Earth‘s surface is very important. The more direct the rays, the more energy each square unit of the surface receives and absorbs.
*The Equator receives the most consistent direct light. (the length of day and night does not change over the year)
*The North and South Pole receive the most inconsistent and indirect light (the length of day and night changes drastically over the year).

your thinking.
Seasons Practice: I Do-
Season’s Independent Practice
1. Create a diagram of Earth and Sun, illustrating how seasons occur.
2. Label: Sun, each season, and the movement of Earth.
3. Explain the motion of the objects and any additional information that is important to understanding why we have seasons.
We have seasons because...

Exit TicketIf Earth’s tilt were to increase from 23.5 degrees to 33.5 degrees the result would be
A) shorter days and longer nights at the EquatorB) less difference between winter and summer
temperatures in TexasC) colder winters and warmer summers in the Northern
HemisphereD) an increase in the amount of solar radiation received by
Earth

Model and Illustrate Earth’s Seasons
A student is given a volleyball, a flashlight, and some paint. Using all or some of the materials given, how could he best model the cause of seasons upon the Earth?
A. Spin the ball in front of the flashlightB. Tilt the ball in one direction while moving it around the
flashlightC. Paint the top half of the ball red and the other half blueD. Shine a bright light on either the top or bottom half of the
ball.
Shade in the Earth to show where the Sun’s light is hitting the surface of the Earth. You will shade the areas that the Sun’s light is NOT hitting.
