There are spheres (planets) other than earth, with gravities of different degree. You can tell that the moon, for instance, has a lower gravity, and that is why it does not pull objects to it as easily. You can show photos of astronauts floating near the moon and struggling to stay on its surface.
If The Earth Is A Round Ball, Why Don”t We Fall Off?
The round, round earth
Left to right, dancing in mirth,
We”re right there, rolling on top
But how come we don”t fall and drop?
The earth has a funny trick:
It has a magic to make us stick.
The name of the magic is gravity
it pulls on everything without disparity.
A wise scholar named Newton discovered long ago
that large objects to each other seek to go.
He found out that anything, even an apple
Will be drawn to the earth until it topples!
Thanks to that magic,
every person, beast and even a stick
become very heavy on the ground
and to the floor are drawn down.
And like the objects, children too
are affected by gravity”s special glue.
With every hop and skip, to earth return anew.
Activity suggestion:
Equipment: some object
Explain to your child that gravity affects every object that is close to earth. Demonstrate how objects that are not held fall to the ground, and emphasize that it is gravity that pulls them down.

In addition, there is the gravity of the sun. The sun projects it on all the planets that circle it, and all of these together are known as the Solar System, because they are moved by it and around it. The earth also rotates around the sun and is subject to its gravity.
