What’s it about?
Even though some forces exist in nature that we are unable to see, we still are able to see what effect such forces, such as ‘gravity’ can have with some interesting science experiments. Gravity can be explained as the force with which the earth attracts bodies near its surface, which in turn affects the weight of an object. Try the following science experiment:

Procedure (Method)
Even though some forces exist in nature that we are unable to see, we still are able to see what effect such forces, such as ‘gravity’ can have with some interesting science experiments. Gravity can be explained as the force with which the earth attracts bodies near its surface, which in turn affects the weight of an object. Try the following science experiment:
- Go to the top floor of a building and weigh yourself with a sensitive bathroom scale – preferably a digital scale that is calibrated in hundred gram intervals. If you live in a town without any tall buildings, you may also use a high hill in this science experiment.
- Now, go down to the first floor of the building or base of the hill and weigh yourself again.
- Notice that according to the scale, you weigh slightly less at the top floor of the building or high hill!
How does it work?
Weight is the measurement of the amount of downward force or ‘gravity’ pulling on an object towards the earth’s surface. An object’s weight decreases the further away it moves from the earth’s surface and the earth’s gravitational pull is the most at the surface.
