Part
1B: Static Electricity
Objectives
After participating in the program Electricity and Magnetism, Part 1B,
students will be able to:
| · relate static electricity to the parts of the atom |
| · express the difference between static electricity and electric current |
| · explain that electrons may be removed from an atom and transferred to another object, leaving that object charged |
| · describe how a discharge or spark is created when electrons jump from one object to another to re-establish charge neutrality |
| · recognize that like charges repel |
| · recognize that opposite charges attract |
| · name several types of static electricity |
Relevant
Vocabulary
| *electroscope | an instrument for detecting very small charges of electricity |
| *static electricity | stationary electrical charges, as those resulting from friction |
