Reasons For the Seasons

   
Summer
·         More light
·         More shadow because there is more light on the surface.
·         The North pole gets more heat
·         The South Pole gets less heat

Winter
·         Less light because the sun is further away
·         Less shadows because the light is further away
·         The poles are colder, because the surface is blocking the poles from the sun

1:When it is winter in the Northern Hemisphere,in the part which receives most sunlight, the Southern Hemisphere, receives summer.
2: In v the summer, there is less shadows because the light is mostly direct. The area gets a bit of the shade but not too much.
3: The heat will increase because the amount of the area that the heat covers will grow. There will now be heat on more of the surface than before.
4: The areas on which it is always cold are the poles. Or, the sides facing up and down on the ball. It is the warmest near the Ecuador or the centre of the ball. This is because the centre of the ball always receive direct light from the lamp, and the poles or the sides facing upward and downward receive the least amount of light because they are the furthest from the sun or the light.
7: The seasons are created by the different positioning of the sun. Where there is most heat and sunlight, it is summer. Where there is the least sunlight and is the coldest. It is winter there. Spring and fall are in between.

  1. Number 2: In the summer, the shadow of the toothpick is much longer than when it is winter because you are right, there is more direct light then.
    Number 3: The heat will decrease because the light is more distributed over a larger area.
    Number 4: EXACTLY!! :) Good explanation and evidence of your learning.
    What happened to 5 and 6?
    Seasons are created by the different positioning of the Earth...because...You explained this well after that. :)

    Overall, a good job. You understood that when the Earth is tilted towards the sun in the Northern hemisphere it would be summer because there is more direct light. Therefore, in the winter it is the opposite.

    How did this model help you?
