-What do you think are the 3 most important things we have learned about static electricity?
1.The laws of static electricity is important because it taught me what charges do to other charges, the law is: like charges repel from each other, opposite charges attract to each other, neutral charges attract to charged object.
2. Negative charges are called electrons, positive charges are protons and neutral charges are neutron. This was important because i got to know what each charges are called and what they are made up of. Objects with negative charges have more electrons than protons, objects with positive charges have more protons than electrons. Neutral objects have equal amounts of protons and electrons.
3.Objects can become charged in two different ways: conduction and induction.
Conduction is when two objects are rubbed against each other, like friction. Induction is when objects get charged by placing it close to a charged object. Objects that are conductors can hold charges and allows electrons to move freely rom one atom to another. For example:copper and other metals. Objects that are insulators do not allow electrons to move freely. For example: plastic, balloon, hair, wood, wool, fur.
– What lab did you find the most helpful in understanding static? Explain how it was helpful.
The Static Discovery Lab was the most helpful because it showed me what objects are conductors and insulators. That lab included most things we learned, like conductors and insulators, attraction or repel of charges. And i learned two ways of knowing if objects carry charges or not: the electroscope and the pop can. When you rub two things together and touch the electroscope with it, and if the leaves inside the electroscope spreads, it means the object carries charges. And if the pop can attract to the object, it means the object carries charges. I also found out what combinations of materials carry the most charges, for example: balloon and hair or fur, Styrofoam and fur.
