The Reasons of the seasons

Hypothesis of activity : How does the tilt of Earth’s axis affect the light received around the sun

Today in science we did a fun experiment called “Reasons of the Seasons”.  We got a Styrofoam ball.   It represented the Earth.  We attached a toothpick at an angle above the middle of the ball and a pencil at the bottom to hold the ball up. Then we got a flashlight to represent the sun.  In a dark room, we used the flashlight to light up the Styrofoam ball in the same way the Sun lights the Earth.  What I noticed on the grid paper was that when light was shined on the table it looked the same but when you shined the light on the ball the shadow created on the grid paper was curved.  I think that this happened since the ball was sphere shaped.  

When it is winter in the Northern Hemisphere, the Southern Hemisphere gets the most light.  When it is summer in the Northern Hemisphere, the most sun light shines in the Northern Hemisphere.   Areas on the equator like Indonesia have a consistently warm temperature all year long because it is always closest to the Sun.  While the areas on the North and South poles are consistently the coolest on Earth since they are always the farthest from the Sun.  The seasons are caused by Earth’s tilt and how the Sun’s light hits the Earth as it rotates on its axis at a 23.5 degree angle.
