|
|
Peel an orange and split it in two (without tearing up any of the pieces of orange).
Imagine that the orange is a mini model of the Sun.
|
Take a felt-tip pen and draw a little dot to mark the middle of it. About how far will you have to go outwards from the middle (the dot) for the temperature in the Sun to become 1 million ºC?
Draw a circle at that distance.
What about 10 million ºC? Draw a circle at this distance in another colour.
The temperature on the surface of the Sun is scarcely 6000 ºC.
Does it give you a good impression of how high the temperature really is in the Sun?
The table of the interior of the Sun also shows where the energy of the Sun is produced.
Draw a circle surrounding the part of the Sun where the greater part of the energy is produced.
Did it get a bit messy when using an orange? Perhaps you may make a model with plastic adhesive – or just draw circles on paper? |
