  2. Static electricity Static electricity occurs when an object that has negatively charged particles meets an object with positively charged particles . There are also objects that are electrically neutral , meaning that they have the same number of positive and negative charges . Rubbing is a way to create static electricity. For example, if you walk across your carpet rug and answer the door , the doorknob will give you a shock . This happens because you pick up negatively charged particles when you first had an overall positive charge, and now you have an overall negative charge from rubbing your feet on the carpet rug. The doorknob has an overall positivecharge, so that’s how you get a shock .

  3. Insulators/conductors • An insulator is an object that doesn’t let materials flow through easily. 4 examples of insulators are plastic, rubber, glass, and dry wood. A conductor is an object that lets materials pass through easily. 4 examples are water, gold, silver, and copper. ***Picture shows example of copper wire. • Insulator/ conductor

  4. Circuits • Every working circuit has at least 3 parts: a power source, which includes a battery, a conductor, {usually a wire}, and an object that uses electric current, such as a light bulb. If you open a circuit, it will not work because electric current can not flow. If you close a circuit, it will work because electric current can flow. The pathway that electric current follows is called an electric circuit. In a series circuit, the parts are connected so that electric current passes through each part, one after another , along a single pathway. In a parallel circuit, the parts are connected so that current passes along more than one pathway.

  5. Bar magnets and electromagnets • 3 similarities in bar magnets include: electromagnets and bar magnets are both magnets; both have a magnetic field; both produce magnetism. • 3 differences in bar magnets and electromagnets include :bar magnet has poles, but an electromagnet doesn’t; a bar magnet is permanent, and a electromagnet is temporary; and a bar magnet is made of magnetite, and an electromagnet is made up of wire, battery, and iron .
