The document discusses static electricity through an experiment. It introduces key terms like electrons, insulators, and conductors. The experiment has students work in groups to observe how rubbing materials like a plastic cup or stick with a handkerchief causes a transfer of electrons, leaving one material positively charged and the other negatively charged. Through pouring water and using other materials, the students can see the effects of this transfer of static charge. The purpose is to demonstrate how static electricity works and which materials more easily allow electron movement.

- 11. Protons have whatwe call a "positive" (+) charge. Electrons have a "negative" (-) charge. Neutrons have no charge, they are neutral. The charge of one proton is equal in strength to the charge of one electron. When the number of protons in an atom equals the number of
- 12. ELECTRONS CAN MOVE Theprotons and neutrons in the nucleus are held together very tightly. Normally the nucleus does not change. But some of the outer electrons are
- 13. They can movefrom one atom to another. An atom that loses electrons has more positive charges (protons) than negative charges (electrons). It is positively charged. An atom that gains electrons has more negative than positive
- 15. Some materials holdtheir electrons very tightly. Electrons do not move through them very well. These things are called insulators. Plastic, cloth, glass and dry air are good insulators. Other materials have some loosely held
- 16. How can wemove electrons from one place to another? One very common way is to rub two objects together. If they are made of different materials, and are both insulators, electrons may be transferred (or moved) from
- 17. The more rubbing,the more electrons move, and the larger the static charge that builds up. (Scientists believe that it is not the rubbing or friction that causes electrons to move. It is
