Benjamin Franklin is acknowledged to be the founder of the theory of atmospheric electricity. He was the first to prove that the lighting was an electrical phenomenon. Franklin developed a new theory of electricity that he called positive and negative. He finally invented a means of protection against the disastrous effects of lighting – the lighting rod. Franklin is known and respected all over the world not only as a scientist but also as a citizen who did as much as he could for the good of his country. Coming out in defence of the Afro-Americans, Franklin declared slavery to be not only an evil from the moral point of view, but also an obstacle to the social interests of America. He is thought to be one of the broadest as well as one of the most creative minds of his time.

A molecule is a group of atoms joined together by chemical bonds. The molecules of an 1_______ are identical and contain atoms of one type only. Oxygen gas, for example, has 2_______ made up of two oxygen atoms. The molecules of a compound are also 3_______, but in this case each molecule 4_______ atoms of more than one type. In water, for example, each molecule is made up of two hydrogen atoms and one oxygen atom. All gases, most liquids, and many nonmetallic solids consist of molecules.

Everything in the world is in motion. Some forms of motion we can see clearly, such as the flight of an airplane. But even objects that seem still, such as rocks and buildings, contains atoms (tiny particles) that move minutely, or vibrate. The Earth itself is moving around the sun, and the entire universe is expanding. All motion requires force to start, to change speed or direction, or to stop.

Your weight is the force that you exert on the Earth. It is a result of gravity acting on your body. Weight differs from mass: your mass is constant whatever the force of gravity. Scientists measure mass in kilograms. This indicates the amount of matter in your body. Scientists measure weight in newtons (N), and 1 kg equals a force of 9.81 N. On the Moon your weight will be much less than it is on Earth because of the less gravity.
